Hi. Thanks for your query., Noted the history recurring colitis, diagnosed as microscopic colitis on colonoscopy and the rest of the reports are normal. You have given up coffee, wine, alcohol, dairy products, cut down on red meat; takes chicken, fish, fruits, cooked vegetables, rice, oatmeal, bananas. When in attack there is tiredness, awful back ache, wants to know whether this is colitis or something else. Since colonoscopy has already been done showing microscopic colitis, the diagnosis is obvious but since other reports are normal we can think of added IBS, that is irritable bowel syndrome or can have intolerance to the products that you have to stop. Only a keen observation will be show the factors that instigate or enhance the problems. You have to stop all these factors. This includes the stress and or anxiety which needs proper control.
