Hydration with an ostomy

Staying hydrated with an ostomy is essential. Drink lots of fluids, choose hydrating foods, and monitor your output to ensure hydration.

Keep the fluids going

Dehydration is a risk with an ostomy because the large intestine now absorbs less fluid. Those with an ileostomy face an even higher dehydration risk.

It's important to drink plenty of fluids, especially on hot or active days. 

Suggested beverages for ostomates

Each person's tolerance for certain fluids may vary, so it's important to monitor how different fluids affect your ostomy output and overall hydration level.


Plain water is the best hydrator.

Sports drinks

Sports drinks can help replace lost sodium, potassium, and other essential electrolytes, but be wary of those with high sugar contents.

Diluted fruit juices

Fruit juices without added sugar provide hydration and some nutrients, but be cautious about sugar and the potential for increased output.

Coffee, tea, and ostomies

Coffee and tea are fine to drink with an ostomy, but caffeinated versions have the ability to dehydrate. Be careful not to use coffee or tea as a substitute for water.

What about alcohol and carbonated drinks?

Alcohol in moderation is fine but remember to keep your water going as well since alcohol is dehydrating. Note that beer may cause bloating and excess gas. Carbonated beverages should also be moderated for the same reason.

What are hydrating foods?

Adding hydrating foods — those with a high water content — to your diet is a good way to improve hydration. These include:

  • Fruits and vegetables
  • Broths and soups
  • Smoothies and juices
