I have an ileo and dehydration is my constant battle. Just 2 days ago, I wound up in the ER AGAIN for 2 liters of fluid. Had just gotten fluid BOTH the previous 2 Thursdays. I can't keep up. The abdominal cramping and weakness eventually get too much and then I get incoherent. sigh. . .
I take codeine-30 mgs up to 4 times a day-- to thicken the output. Some days, I only need 2 tablets and some days, just immodium.
It took about 6 months for me to start really seeing thicker output. There aren't many foods that thicken my output: white rice, potatoes (NOT sweet potatoes), french fries (not spicy curl fries), peanut butter, potato chips (baked or regular), bread and honey, saltines. I have not tried popcorn--I'm too scared.
Items that help with my dehydration: chicken broth, popsicles, powerade, v8, water with fruit (let some grapefruit or oranges sit in the water in the fridge), jello with canned fruit, lemon ice, sorbet without pulp or seeds, smoothie (juice, sorbet, ice, fruit, agave nector, little yogurt).
You're not alone. Best of luck!!
