Trekking in Nepal after ostomy surgery can be an exciting adventure, especially if you're feeling healthy and active. If you're planning a trip like this, here are some helpful tips and advice to ensure you're well-prepared for your journey:

1. Hydration
- Make sure to carry plenty of water while on the trail. Adding electrolyte powders or drops can help keep you hydrated.
- Consider using products like H2ORS oral rehydration powder or general hydration salt sachets.

2. Medical Preparation and Safety
- Schedule a minor check-up with your doctor before you leave.
- Take photos of your prescription labels and pack all your regular medications. It's also wise to bring antihistamines, anti-diarrhea tablets like loperamide, and pain relievers such as Tylenol.
- Identify the nearest hospitals or clinics along your trekking route in case of emergencies.
- Teach your trekking partner, like your son, how to change or empty your pouch if necessary.
- Be aware that some people feel the remote nature of the region might pose risks.

3. Ostomy Supplies and Packing
- Bring more pouches, wafers, and accessories than you think you'll need.
- Split your supplies between your carry-on and checked luggage to ensure you have what you need if one bag is lost.
- Consider alternative support garments, such as Ostomy Secrets wraps, in addition to your Stealth Belt.

4. In-flight Management (Long-haul Tips)
- Avoid solid food for about six hours before your flight to reduce output.
- Be prepared to empty your pouch twice on a 12-hour flight. Airplane lavatories are cramped, so sitting high on the seat can make emptying easier and less messy.
- Pack disposable bags pre-loaded with a bit of toilet paper and an absorption sachet for discreet emptying and disposal.

5. Trekking-specific Pointers
- Always carry extra water and sports drinks while hiking.
- Keep small "ready kits" with pouch-change items and waste bags in your daypack.
- Having someone who knows your routine can be helpful if you injure an arm or need assistance.

By following these tips, you can focus on enjoying your trekking adventure in Nepal with peace of mind.
