Yellow Stool in Related Issues & Disorders Posted July 19, 2010 · Report to Admin Yep. I've been having this problem since January. Sometimes it is just loose but many times I have D, there is undigested fat and and very malodorous. There has been times I have barely made it to the bathroom. In Feb. I had a gallbladder ultrasound (normal) and Hida scan (suboptimal but above the sugical thrrshold), some stool testing in March for parasites/pathogens (normal), and a repeat EGD and biopsy in April (esophagitis, gastritis, stomach ulcer but normal small biopsy this time). I went dairy free thinking it was causing my symptoms and also cracked down on potential CC. I got worse. I definately am not digesting fats well. Avocados and the almond milk will really set me off as well as anything greasy or fried. On my last visit I tried a trial of welchol to control the diarrhea. It helped some but not enough to care. The GI also suggested that I may have a pancreas problem because of the fat in the stool. I'm supposed to call back and let him know about the welchol. I also decided on my own to try some digestive enzymes. They helped more than the welchol (although I was not able to take it exactly as prescribed because of the drug interacting with my thyroid meds), but I ran out and I'm waiting on them in the mail. I think the reason I'm not digesting fats is because of my dysfunctional gallbladder. However the doctor said he thinks I would be hard pressed to find a surgeon to take it out when it is working at 48% when the threshold for surgery is 35%. He did say he likes to see the function at least 50%. I do have RUQ discomfort, but never severe pain. It's more of a pinching/pulling sensation that is very annoying. I'm going to go really low fat for awhile and see how I react. If I still have problems I may go in for more testing/surgical consult. I'm getting very discouraged by all this, tired and a sore butt! what digestive enzymes are you taking?
