Dehydration
When you suffer from constant diarrhea or if you don’t drink enough water because the disorder makes you feel nauseous, dehydration can be a problem. One of the first signs is thirst; others include a dry mouth, headache, feeling weak when you stand up, and energy shortage. Try to keep a bottle of fresh water handy. Ice pops can help beat dehydration if drinking feels more than your belly can handle.
