Microscopic colitis

I have had fat malabsorption for over two years now. I have lost 30 lbs and can't gain anything back.They have ruled out celiac, crohn's, cf, pancreas.My GI doctor now wants to test for Microscopic Colitis. I do sometimes have watery bm's but most of the time they are just loose. Ballpark 2 to 3 times a day if I watch what I eat, several more if I eat whatever. Does This sound like Microscopic Colitis? What other conditions cause Fat malabsorption that have not already been mentioned. I do have a white cell count that is a little low as well as blood platelets that are a little low.Vitamin and mineral def. Sometimes night sweats. I have Hyperparatyhroidism as well as familial Hypercalcemia but the levels for both have been fine over the past 2 yrs.

Hi Jimmy583,
Most of the cases of microscopic colitis are associated with intake of NSAID medications ( are you taking any NSAID) - but not in all cases.
Microscopic colitis can cause weight loss. Diarrhea usually stops with fasting.
A biopsy  alone from the colon can confirm the diagnosis.

But since you have problems like vitamin and mineral deficiency as well, small intestinal problem is more probable than microscopic colitis.

The list of causes of fat malabsorption is very long and all cannot be mentioned here
