I have been diagnosed with microscopic colitis. I have not had tests to check for malabsorption syndrome, but I have lost 40 pounds in a year and a half since this diarrhea started. I also have fecal incontinence at times. My diet now consists of rice, chicken and fish, mostly fatty fish, like salmon. I also take Kefir and probiotics (bifidobacterium and rhamnosus), along with beets. I stopped taking pectins and fiber because they exacerbated the watery diarrhea. Budesonide has no effect except constipation/more diarrhea. I have an antispasmodic, chlordiazopoxide/clidinium, and loperamide as my agents of relief. Would mesalamine or sulfosalazine help? I have Rheumatoid arthritis, and also take methotrexate and injectable Humira.
