Constipation. Diet rich in fibers, fruits and veggies, plenty of fluids. Laxatives if necessary.
Fluids. Consuming 20-25 grams of fiber per day and drinking 80-100 ounces of non caffeinaqted non alcoholic fluids per day regularly and adding 20 ounces per 30 minutes of excercise, works for most people with uncomplicated constipation. Excercising regularly also keeps the bowels moving.
