Trekking Nepal with Pre-Existing Health Conditions: Complete Medical Guide

Having a pre-existing health condition does not automatically disqualify you from trekking in Nepal. Every year, thousands of trekkers with asthma, diabetes, heart conditions, knee problems, anxiety, allergies, and other medical conditions successfully complete treks ranging from the moderate Poon Hill circuit to the demanding Everest Base Camp route. The key is honest preparation, medical consultation, appropriate trek selection, and smart management strategies on the trail.

That said, trekking in Nepal is not a casual walk in a park. You are hiking at altitude in remote locations, hours or days from proper medical facilities, in conditions that test even perfectly healthy individuals. A pre-existing condition adds an additional layer of complexity that requires careful planning. The altitude itself affects how your body responds to medication, how your condition behaves, and what risks you face. The remoteness means that if something goes wrong, help may be far away.

This guide covers the most common pre-existing conditions that trekkers bring to Nepal's mountains. For each condition, we address: can you still trek? What precautions should you take? Which treks are most appropriate? And what should you discuss with your doctor before booking your trip?

The Universal Preparation Checklist

Regardless of your specific condition, every trekker with a pre-existing health condition should complete these steps before trekking in Nepal.

Before You Book

1. Schedule a dedicated pre-trek medical consultation with your doctor. Bring your intended itinerary, including altitudes, daily distances, and duration
2. Get a written medical clearance letter stating you are fit to trek at altitude (specify the maximum altitude). This is useful for insurance and for your own peace of mind
3. Review your medications with your doctor, specifically asking about altitude interactions and effects
4. Discuss emergency scenarios -- what should you do if your condition worsens on the trail?
5. Purchase travel insurance that covers pre-existing conditions. Many standard policies exclude them. See our travel insurance guide
6. Create a medical information card listing your conditions, medications, allergies, and emergency contacts. Carry it on your person and give a copy to your guide

Before You Depart

7. Carry sufficient medication for the entire trip plus 5-7 extra days (in case of delays)
8. Split medications between your day pack and main bag (in case one is lost)
9. Carry medications in original labeled packaging (important for customs and for identification)
10. Get a doctor's letter for any controlled medications or injectable medications (for airport security)
11. Research medical facilities along your route and in Kathmandu
12. Inform your trekking guide about your condition, medications, and emergency plan

Asthma at Altitude

Can You Trek with Asthma?

Yes, most people with well-controlled asthma can trek successfully in Nepal. In fact, many asthma sufferers report that their symptoms improve at altitude because the air is cleaner, less polluted, and has fewer allergens (especially above treeline where dust, pollen, and mold are minimal).

However, there are important caveats: cold dry air at altitude can trigger exercise-induced bronchoconstriction, the reduced oxygen at altitude means less margin if your breathing is already compromised, and some asthma medications interact with altitude physiology.

How Altitude Affects Asthma

Potentially Helpful:

• Less air pollution than Kathmandu (which has significant pollution)
• Fewer allergens at high altitude (less pollen, mold, dust mites above 2,500m)
• Cleaner air in mountain environments

Potentially Harmful:

• Cold, dry air is a known asthma trigger -- and air gets colder and drier with altitude
• Exercise intensity increases at altitude (you are working harder for the same pace)
• Respiratory infections are more common on treks (shared tea houses, close quarters)
• Smoke from cooking fires and kerosene heaters in tea houses can trigger symptoms

Precautions for Asthmatic Trekkers

| Precaution | Details | |-----------|---------| | Carry rescue inhaler at ALL times | In your jacket pocket, not buried in your pack. Altitude does not affect inhaler effectiveness | | Bring adequate supply | Two rescue inhalers minimum; preventer inhaler for full trip plus 7 days extra | | Use preventer inhaler consistently | Do not skip doses, even if you feel better at altitude | | Pre-treat before cold exposure | Use rescue inhaler 15-20 minutes before cold morning starts | | Cover mouth and nose | A buff or balaclava warms and humidifies inhaled air | | Monitor peak flow if possible | Bring a mini peak flow meter for objective lung function monitoring | | Avoid smoke exposure | Request non-smoking dining areas; ventilate rooms with heaters | | Hydrate aggressively | 3-4 liters per day; hydrated airways produce less mucus | | Carry a short course of oral prednisolone | For severe attacks; discuss with doctor pre-trip |

Appropriate Treks for Asthma

| Trek | Max Altitude | Suitability | Notes | |------|-------------|-------------|-------| | Poon Hill | 3,210m | Excellent | Lower altitude, shorter duration | | Annapurna Base Camp | 4,130m | Good | Moderate altitude, sheltered valley | | Langtang Valley | 4,984m | Good | Gradual ascent, tea houses throughout | | Everest Base Camp | 5,364m | Good with precautions | Standard itinerary allows good acclimatization | | Annapurna Circuit | 5,416m | Good with precautions | Thorong La is the main challenge | | Three Passes Trek | 5,535m | Caution | Multiple high passes; consult doctor |

Diabetes Management on Trek

Can You Trek with Diabetes?

Yes, both Type 1 and Type 2 diabetes can be managed on Nepal treks, but it requires significantly more planning and monitoring than for non-diabetic trekkers. The combination of extreme exercise, variable diet, altitude effects on metabolism, and distance from medical care creates a complex management challenge.

How Altitude and Trekking Affect Diabetes

Blood sugar effects:

• Intense sustained exercise (trekking 6-8 hours daily) generally lowers blood sugar
• Altitude itself may affect blood sugar readings in both directions (studies show variable results)
• Stress and altitude hormones can raise blood sugar
• Appetite loss at altitude may reduce food intake, risking hypoglycemia
• Food timing is less predictable (meals depend on reaching tea houses)
• The type of food available (high carbohydrate, dal bhat-heavy) differs from your normal diet

Insulin-specific concerns:

• Insulin can freeze at altitude if not kept warm (freezing destroys insulin)
• Some glucose meters give inaccurate readings at altitude or in cold temperatures
• Insulin absorption rates may change with altitude and temperature
• Insulin needs may change significantly with the extreme daily exercise

Diabetes Management Checklist for Nepal Treks

| Item | Quantity | Notes | |------|----------|-------| | Insulin (if applicable) | Full trip supply plus 50% extra | Split between two insulated cases | | Insulated insulin case | Two (backup in case one fails) | Frio cooling wallets or similar | | Glucose meter | Two (primary and backup) | Test altitude accuracy before trek | | Test strips | Triple your normal usage | Cold and altitude increase checking frequency | | Lancets | Triple normal supply | Hygiene is harder on trek; change more often | | Glucose tablets/gel | 15-20 treatments minimum | Fast-acting hypoglycemia treatment | | Glucagon emergency kit | One | Ensure trekking partner and guide know how to use it | | Snacks | Ample supply | Granola bars, dried fruit, nuts for between meals | | Medical ID bracelet | Worn at all times | In English and Nepali if possible | | Doctor's letter | Carried on person | For customs (needles/insulin) and emergency care |

Blood Sugar Monitoring at Altitude

• Check more frequently than at home: before and after meals, before and after trekking, before bed, and during the night if concerned
• Be aware that some meters are affected by altitude and cold. The Contour Next and Freestyle Libre systems are generally considered more reliable at altitude, but test your specific meter before the trek
• Carry a written record of your readings and share with your guide
• Know that symptoms of hypoglycemia and altitude sickness overlap: dizziness, confusion, fatigue, nausea. If in doubt, check your blood sugar before assuming it is altitude sickness

Appropriate Treks for Diabetic Trekkers

Lower altitude treks with shorter daily distances, reliable tea house meals, and easier evacuation options are generally more appropriate for diabetic trekkers, especially those on insulin.

• Best options: Poon Hill (3,210m), Ghorepani-Ghandruk loop, lower Annapurna approaches
• Moderate options: Annapurna Base Camp (4,130m), Langtang Valley, shorter EBC itineraries with extra rest days
• Possible with extensive planning: Full EBC, Annapurna Circuit (discuss thoroughly with your endocrinologist)

Heart Conditions

Can You Trek with a Heart Condition?

It depends entirely on the specific condition, its severity, and its current management. This is one area where you absolutely must get specialist clearance before even considering a Nepal trek.

Conditions that generally allow trekking (with clearance and appropriate trek selection):

• Well-controlled hypertension (high blood pressure)
• History of resolved cardiac events with full cardiac rehabilitation
• Mild valvular heart disease (assessed by a cardiologist)
• Well-controlled arrhythmias
• Stable coronary artery disease with good exercise tolerance

Conditions that generally preclude high-altitude trekking:

• Uncontrolled or poorly controlled hypertension
• Recent heart attack (within 6-12 months, depending on severity)
• Severe heart failure (NYHA Class III-IV)
• Unstable angina
• Uncontrolled arrhythmias
• Severe valvular disease
• Pulmonary hypertension

How Altitude Affects the Heart

At altitude, your cardiovascular system works harder to compensate for reduced oxygen:

• Heart rate increases (10-20% higher than sea level)
• Blood pressure may rise at altitude, particularly in the first few days
• Cardiac output increases to deliver more oxygen-carrying blood
• Blood viscosity increases (the body produces more red blood cells at altitude, thickening the blood)
• Pulmonary artery pressure increases (relevant for those with pulmonary hypertension)

For a healthy heart, these adaptations are well-tolerated. For a heart with existing limitations, they can push it past its capacity.

Precautions for Cardiac Trekkers

1. Get a cardiac stress test before your trek. Your doctor needs to know your exercise capacity at sea level to estimate how you will perform at altitude
2. Carry a complete list of medications with generic names (brand names vary by country)
3. Bring extra blood pressure medication -- blood pressure often increases at altitude
4. Discuss aspirin and blood thinners with your cardiologist (altitude increases blood viscosity; your anticoagulation plan may need adjustment)
5. Know your limits. Choose a trek that stays within your tested exercise capacity
6. Never push through chest pain or unusual breathlessness. These symptoms at altitude demand rest and potential descent
7. Stay extra hydrated -- dehydration at altitude worsens blood viscosity
8. Ascend slowly -- add extra rest days to standard itineraries

Appropriate Treks for Cardiac Conditions

| Condition (Well-Controlled) | Maximum Recommended Altitude | Best Trek Options | |----------------------------|------------------------------|-------------------| | Hypertension | Discuss with cardiologist; often up to 5,000m | Any, with clearance and monitoring | | Post-cardiac event (fully recovered) | Usually up to 3,500-4,500m | Poon Hill, lower Annapurna, Langtang (partial) | | Mild valvular disease | Discuss with cardiologist | Lower altitude treks; Poon Hill, Helambu | | Stable coronary artery disease | Usually up to 3,500-4,000m | Poon Hill, Ghandruk, lower routes | | Controlled arrhythmias | Discuss with cardiologist | Depends on type and control |

Knee and Joint Issues

The Most Common Trek-Limiting Condition

Knee and joint problems are the single most common pre-existing condition that affects Nepal trekkers. The prolonged descents -- hundreds of stone steps, steep downhill sections for hours at a time -- are brutal on knees, even healthy ones. For trekkers with existing knee issues (previous ACL injuries, meniscus tears, osteoarthritis, runner's knee, IT band syndrome), the descents can be the trip-defining challenge.

The Nepal Descent Problem

What makes Nepal treks particularly hard on knees is not the ascents -- it is the descents. Consider the Everest Base Camp trek: after reaching EBC at 5,364m, you descend approximately 2,500 vertical meters back to Lukla over 3-4 days, much of it on stone steps. The Annapurna Circuit descent from Thorong La (5,416m) to Muktinath (3,800m) drops 1,600m in a single day. These are knee-destroying distances for unprepared joints.

Prevention and Management Strategies

| Strategy | Details | When to Start | |----------|---------|---------------| | Trekking poles | Reduce knee impact by 25-30% on descents | Use from Day 1; practice before trek | | Knee braces or supports | Compression sleeves or hinged braces | Wear on descent days | | Strengthen quads and hamstrings | Strong leg muscles protect knee joints | 3-6 months before trek | | Anti-inflammatory medication | Ibuprofen for inflammation (not just pain) | As needed on trek | | Glucosamine supplements | May support joint health (evidence mixed) | 2-3 months before trek | | Descend slowly | Take small, controlled steps on stairs | Every descent | | Zigzag on steep descents | Reduces direct impact on knees | Steep sections | | Regular stretching | Quad, hamstring, and IT band stretches daily | Daily on trek | | Ice packs (if available) | Reduce swelling after long descent days | Evening after trekking | | Consider helicopter return | Flying Lukla-Kathmandu or similar saves major descent | Plan in advance |

Appropriate Treks for Knee Issues

The key factors are: how much descent is involved, how steep the descents are, and whether alternatives exist (helicopter options, shorter routes).

Better Options (Less Descent):

• Poon Hill: Moderate descents, stone steps but manageable distance
• Mardi Himal: Less descent than ABC; newer trail with less stone step infrastructure
• EBC with helicopter return from Lukla: Eliminates the Lukla-Kathmandu descent via Jiri
• Upper Mustang: Relatively gentle terrain, jeep road available as backup

More Challenging (Significant Descent):

• EBC standard: The descent from EBC to Lukla is demanding on knees
• Annapurna Circuit: The Thorong La descent is very steep; 1,600m in one day
• Three Passes Trek: Multiple steep pass descents

Mental Health: Anxiety and Depression

The Overlooked Category

Mental health conditions are rarely discussed in trekking preparation, but they are surprisingly common among trekkers and can significantly impact the experience. Anxiety, depression, panic disorder, and PTSD all present unique challenges in the trekking environment.

How the Trekking Environment Affects Mental Health

Potential Triggers:

• Isolation and remoteness: Being days from roads and hospitals can trigger anxiety
• Physical discomfort: Cold, fatigue, and altitude symptoms can worsen depression or trigger panic
• Altitude itself: Mild cognitive effects of altitude (poor concentration, irritability, sleep disruption) can mimic or worsen anxiety and depression symptoms
• Sleep disruption: Poor sleep at altitude (common) destabilizes mood and increases anxiety
• Loss of routine: Regular sleep, exercise, and eating patterns are disrupted
• Group dynamics: Trekking with unfamiliar people in challenging conditions can be stressful
• Health anxiety: Monitoring for altitude sickness symptoms can trigger health-anxious individuals into hypervigilance

Potential Benefits:

• Nature therapy: Immersion in natural environments has documented positive effects on mental health
• Physical exercise: Regular exercise is a proven mood enhancer
• Achievement and purpose: Completing a challenging trek builds self-efficacy and confidence
• Disconnection from digital life: Being offline can be profoundly restorative
• Community: Shared challenges create meaningful connections with fellow trekkers

Medication Considerations

| Medication Type | Altitude Considerations | Notes | |----------------|------------------------|-------| | SSRIs (sertraline, fluoxetine, etc.) | Generally safe at altitude | Continue normal dose; altitude may slightly affect absorption | | SNRIs (venlafaxine, duloxetine) | Generally safe at altitude | Do not stop suddenly; carry extra supply | | Benzodiazepines (diazepam, alprazolam) | Caution at altitude | Can suppress breathing, which is dangerous when oxygen is already low; discuss with doctor | | Beta-blockers (propranolol for anxiety) | Caution at altitude | May impair altitude acclimatization; discuss alternatives | | Sleep medications | Caution at altitude | Sleeping pills that suppress breathing are dangerous at altitude | | Buspirone | Generally safe at altitude | Limited data; consult doctor |

Strategies for Trekking with Anxiety

• Choose a guided trek rather than independent trekking. Having an experienced guide reduces uncertainty and provides a safety net
• Select a trek within your comfort zone. This is not the time for your first-ever high-altitude experience if your anxiety is severe. Start with a lower, shorter trek
• Bring comfort items -- a favorite book, music player, photos, anything that grounds you
• Practice breathing techniques before the trek. Box breathing and 4-7-8 breathing are effective for acute anxiety
• Inform your guide and trekking partner about your condition so they can provide support without judgment
• Set realistic expectations. Some discomfort is normal. Not every headache is altitude sickness. Not every moment will be enjoyable
• Have an exit strategy. Knowing you can turn back or arrange helicopter evacuation at any point reduces the feeling of being trapped

Allergies on Trek

Food Allergies

Managing food allergies on Nepal treks requires preparation because:

• Language barriers make communicating allergies to kitchen staff challenging
• Cross-contamination is common in basic tea house kitchens
• Ingredient knowledge varies among tea house cooks
• Limited menu options mean fewer alternatives if you cannot eat the standard dishes

Preparation strategies:

• Learn key allergy phrases in Nepali. "Malaai [allergen] bata allergy chha" (I am allergic to [allergen])
• Carry allergy translation cards in Nepali (available online or create with your guide's help)
• Bring your own safe snacks and backup food
• If you have a severe (anaphylactic) allergy, carry two epinephrine auto-injectors and ensure your guide knows how to use them
• Consider carrying a portable meals supply (freeze-dried meals) as emergency backup

Common allergens in Nepali trekking food:

• Peanuts/tree nuts: Used in some Nepali dishes and snacks
• Dairy: Dal bhat is usually dairy-free, but many other dishes contain milk, butter, or cheese
• Gluten: Rice-based dal bhat is naturally gluten-free, but noodle dishes, bread, and Tibetan bread contain wheat
• Eggs: Used in many tea house breakfast options

Environmental Allergies

• Pollen: Spring treks (March-May) may be challenging for pollen-sensitive trekkers, particularly through rhododendron forests
• Dust: Lower altitude trails, especially those shared with pack animals, can be dusty
• Mold: Older tea houses with damp conditions may have mold
• Animal dander: Yaks, mules, and dogs are common on trekking routes

Carry: Antihistamines (cetirizine or loratadine), nasal corticosteroid spray, and any prescribed allergy medications

Medications at Altitude: General Considerations

Altitude affects how your body absorbs, distributes, metabolizes, and excretes medications. While most medications work normally at trekking altitudes (up to 5,500m), some important interactions exist.

Medications That May Be Affected by Altitude

| Medication | Altitude Effect | Action | |-----------|----------------|--------| | Blood pressure medications | BP may rise at altitude; may need dose adjustment | Monitor BP if possible; consult doctor | | Insulin | Absorption may change; needs may vary with exercise | Monitor blood sugar more frequently | | Oral diabetes medications | Exercise at altitude may increase hypoglycemia risk | Monitor blood sugar; carry glucose | | Blood thinners (warfarin) | Altitude increases blood viscosity; may need adjustment | Discuss with hematologist before trek | | Diuretics | Dehydration risk amplified at altitude | Extra hydration; monitor closely | | Beta-blockers | May impair altitude acclimatization | Discuss with cardiologist | | Benzodiazepines/sedatives | Respiratory suppression dangerous at altitude | Avoid if possible; discuss alternatives | | Oral contraceptives | Theoretical increased DVT risk at altitude (unproven) | Stay hydrated; move regularly | | Corticosteroids | Can mask altitude sickness symptoms | Continue if prescribed; be aware of masking | | Thyroid medications | Altitude may affect thyroid function slightly | Continue normal dose; monitor symptoms |

General Medication Tips for Altitude

• Never stop prescribed medications for the trek without doctor's approval
• Carry all medications in carry-on luggage when flying (in case checked bags are lost)
• Bring medications in original, labeled packaging (important for customs)
• Carry a doctor's letter listing all medications with generic names and dosages
• Protect medications from extreme temperatures (cold at altitude, heat in sun)
• Set alarms for medication schedules -- altitude and trek exhaustion can make you forget

Practical Considerations for All Conditions

Choosing the Right Trek

When selecting a trek with a pre-existing condition, prioritize:

1. Lower maximum altitude (less physiological stress)
2. Gradual ascent profile (more time to acclimatize)
3. Shorter daily distances (less physical stress)
4. Good tea house infrastructure (comfortable rest, warm food)
5. Proximity to evacuation options (helicopter landing sites, roads)
6. Availability of medical facilities (HRA clinics, health posts)

Recommended Lower-Stress Treks

| Trek | Max Altitude | Days | Why It Works | |------|-------------|------|-------------| | Poon Hill/Ghorepani | 3,210m | 4-5 | Low altitude, short duration, excellent infrastructure | | Ghandruk Loop | 2,012m | 3-4 | Very low altitude; cultural experience | | Nagarkot to Dhulikhel | 2,175m | 2-3 | Close to Kathmandu; easy evacuation | | Mardi Himal (lower section) | 3,580m | 5-6 | Moderate altitude; beautiful views | | Helambu | 3,640m | 5-7 | Close to Kathmandu; gradual terrain | | Langtang Valley (to Kyanjin) | 3,830m | 7-9 | Moderate altitude; road access at start |

Communication and Emergency Planning

• Satellite communicator (Garmin inReach or similar) allows emergency messaging from anywhere
• Share your itinerary with family and your doctor at home
• Register with your embassy in Kathmandu
• Know helicopter evacuation procedures -- see our helicopter rescue guide
• Ensure your guide knows your condition and has your emergency contacts

Frequently Asked Questions

Do I need to disclose my health condition to my trekking agency?

You are not legally required to disclose health conditions to your trekking agency, but it is strongly recommended and arguably essential for your safety. Your guide needs to know about your condition so they can monitor you appropriately, carry relevant emergency supplies, and make informed decisions if something goes wrong. A guide who does not know about your insulin dependence, for example, cannot help you if you experience severe hypoglycemia. Most reputable agencies ask about health conditions on their booking forms and treat the information confidentially.

Will my pre-existing condition void my travel insurance?

It can, if you did not disclose it when purchasing the policy. Most travel insurance policies require you to declare pre-existing conditions. If you fail to declare a condition and then file a claim related to that condition, the claim will almost certainly be denied. Many insurers offer coverage for pre-existing conditions at additional cost. Always disclose; the extra premium is far cheaper than an uninsured emergency. See our travel insurance guide for providers that cover pre-existing conditions.

Can I get my regular medications in Kathmandu if I run out?

Kathmandu has well-stocked pharmacies, and many medications are available over the counter without prescription. However, brand names differ from Western countries, dosages may vary, and quality control is less stringent for some locally manufactured medications. For critical medications (insulin, cardiac medications, anti-seizure drugs), always bring more than enough from home. For common medications (antibiotics, anti-inflammatories, antihistamines), Kathmandu pharmacies are generally reliable.

I have asthma -- will the altitude make it worse or better?

It varies by individual. Many asthmatics find that their symptoms improve at altitude because the air is cleaner and has fewer allergens than at sea level (or in polluted Kathmandu). However, cold dry air is a known asthma trigger, and exercise at altitude demands more respiratory effort. The net effect depends on your specific triggers. If your asthma is primarily allergic, altitude may help. If cold air is a major trigger, altitude presents challenges. Carrying your rescue inhaler at all times and pre-treating before cold exposure are essential regardless.

How do I store insulin on a trek in freezing temperatures?

Keep insulin close to your body during the day -- an inside jacket pocket, in a pouch under your layers, or in a Frio cooling wallet (which prevents both overheating and freezing). At night, place insulin inside your sleeping bag with you. Never leave it in your main backpack overnight in a cold tea house room, and never leave it in direct sunlight during the day. The temperature range for insulin storage is 2-30°C. If insulin freezes, it is permanently damaged even if it thaws -- discard it and use a fresh supply.

I take blood pressure medication. Should I bring a portable blood pressure monitor?

It is a good idea if your hypertension requires close management. Small, portable wrist blood pressure monitors weigh very little and can provide valuable data. Blood pressure often increases during the first few days at altitude before stabilizing. If you notice consistently elevated readings (or symptoms like persistent headache, visual disturbances, or nose bleeds), you may need a medication adjustment -- discuss this scenario with your doctor before the trek so you have a plan.

Can I trek with a knee replacement?

Many people trek successfully after knee replacement, but timing and trek selection matter. Most orthopedic surgeons recommend waiting at least 6-12 months after surgery and completing full physical therapy. The artificial joint should have full range of motion and strength. Lower-altitude treks with moderate descents are most appropriate initially. Trekking poles are essential. The stone steps on many Nepal trails are the biggest challenge for replaced knees -- choose trails with more gradual terrain when possible.

I have anxiety about altitude sickness -- is this normal?

Completely normal. Altitude anxiety is one of the most common forms of pre-trek worry, and it is amplified by reading about altitude sickness dangers (including guides like this one). The key distinction is between healthy awareness (knowing the symptoms, having a plan, acclimatizing properly) and unhealthy obsession (constant symptom checking, catastrophizing, inability to enjoy the trek). If your anxiety about altitude is severe, consider: starting with a lower-altitude trek to build confidence, trekking with a guide who can provide reassurance, learning about altitude sickness so you feel informed rather than fearful, and speaking with a mental health professional before your trip.

Are there any health conditions that absolutely prevent trekking in Nepal?

Very few conditions are absolute contraindications for all Nepal trekking, because Nepal offers such a range of treks -- from easy lowland walks to extreme high-altitude expeditions. However, certain conditions may preclude high-altitude trekking specifically: uncontrolled serious cardiac conditions, severe or uncontrolled pulmonary hypertension, recent stroke or transient ischemic attack, unstable epilepsy, severe uncontrolled diabetes, and active psychosis. Even with these conditions, lower-altitude cultural walks and valley treks may still be possible. The determination must be made by your doctor with knowledge of your specific situation and the specific trek.

How do I manage celiac disease or gluten intolerance on a Nepal trek?

The good news is that Nepal's staple trekking meal -- dal bhat -- is naturally gluten-free (rice, lentil soup, vegetables, pickles). If you eat primarily dal bhat, you can manage gluten avoidance fairly well. The challenges are: noodle dishes (contain wheat), Tibetan bread, chapati, some soup thickeners, and soy sauce (used in some dishes). Carry a gluten allergy card in Nepali, ask your guide to communicate with kitchen staff, and when in doubt, stick to rice-based meals. Carrying gluten-free snacks from home provides a safety net.

Should I tell other trekkers about my health condition?

You are not obligated to, but telling at least your trekking partner is wise for safety reasons. If you have a condition that could cause a sudden emergency (severe allergy, insulin-dependent diabetes, seizure disorder, cardiac condition), having people around you who know what is happening and how to help could save your life. You do not need to announce it to the entire group, but your immediate trekking companions and your guide should know.
