Antibiotics impact on digestion

[GKT1969]

hello, I have posted here many times and I am grateful for then advise and suggestions from fellow IBS sufferers. I have over 15 bowel movements daily, they are muddy and substantial. I exist in two states; on the toilet or thinking about going to the toilet. It’s horrible. As you can imaging 8 have had every test and procedure known to man and nothing has ever been found. Until now. I sent samples to an affiliated of the CDC and the tests showed I have mycobacterium Avium complex (MAC] a bacteria that primarily infects the lungs. My wife primary care doctor believes this infection is the root cause of my digestive issues. He prescribed 3 antibiotics taken 7 times every other day for a year. Yikes! I don’t not exhibit any of the primary symptoms caused by MAC so I am concerned this is not related to my IBS. I followed the prescription for a couple of weeks and in this time my stools went from thick and muddy to watery with food particles clearly visible. And the bowel movements are much more difficult to control. My question is has anyone had positive or negative reactions to antibiotics or share my concern about the frequency and length of time for the prescription. Or if my reaction to the antibiotic might actually provides some clues on whether my overall symptoms might indeed be caused by a bacterial infection. Thanks as always for taking the time to read and to respond to my posts
