NUTRITION AND HYGIENE

A high-altitude expedition is a demanding test not only for your fitness but also for your palate and entire digestive system.

 

The altitude itself and the change:

 

➤ quality of food

➤ quantity of meals

➤ type of products

➤ flavors and preparation methods

 

can lead to a decrease in appetite.

 

 

 

 

ENERGY REQUIREMENTS IN THE MOUNTAINS

 

During climbing, the body uses huge amounts of energy. Therefore, it is important to provide high-energy foods, mainly based on carbohydrates.

 

A carbohydrate-rich diet helps:

 

➤ reduce body weight loss

➤ decrease muscle mass loss

➤ maintain endurance during exertion

 

 

 

 

At extreme altitudes (6000–8000 m), the situation becomes even more challenging. Oxygen-deprived intestines do not fully digest the consumed food, so nutrient absorption is limited.

 

 

ENERGY DURING CLIMBING

 

In the mountains, you burn a lot of calories, so it's important to regularly provide easily digestible energy.

 

The best options are:

 

➤ energy bars

➤ energy gels

➤ other quick sources of carbohydrates

 

A good habit is also to provide an additional approximately 500 kcal per day, even when you feel full.

 

 

 

 

HYGIENE IN THE CAMP

 

One of the most important rules in the mountains is hand hygiene.

 

They should be washed:

 

➤ before every meal

➤ after every visit to the latrine

 

Organizing a shared sanitation area is nothing new — even in Napoleon's army, building latrines was a fundamental principle of camp functioning.

 

Mountains are not a festival of flying toilet paper.

 

 

 

 

TRAVELERS' DIARRHEA

 

Travelers' diarrhea is a common issue in the first days of the expedition when the body is getting used to new food and local conditions.

 

The risk of its occurrence can be reduced through prevention.

 

Dietitians recommend taking probiotics containing Saccharomyces boulardii:

 

➤ even up to 4 weeks before departure

➤ and in the first two weeks of the expedition

 

 

MANAGEMENT IN CASE OF DIARRHEA

 

If diarrhea occurs:

 

➤ drink plenty of fluids

➤ preferably use electrolyte solutions

 

Helpful may be products used in sports and travel medicine, e.g.:

 

➤ Gastrolit – 1 sachet dissolved in 200 ml of warm water after each bowel movement

 

If symptoms persist longer, stronger medications can be used, such as:

 

➤ Loperamide

➤ Xifaxan
