I had a colostomy reversal 5 weeks ago, I had 6 inches of my colon removed due to diverticulitis and had a temp colosotmy, my doctor said what ever I do do not get constapated, I took milk of magnesia yesterday morning, which seem to work fine, but then started having diarrea about noon time, now every time I drink anything, water or decafinnated ice tea, I am going to the bathroom. Should I worry about dehaydration, what should I eat and when should I seek medical treatment for this?
