<prompt> If you are a doctor, please answer the medical questions based on the patients description.Why am I having green stools for three weeks?? Medical background I ve been suffering with IBS-like symptoms my whole life, but have never gone to a gastroenterologist for finacial reasons and I was also recently diagnosed with NAFLD and I have been taking macrobid for 6 months. I have also recently noticed that I am getting chills. I also have noticed the new appearance of 2 tiny red dots moles? on my left breast. Although my father has many red moles, so it may be nothing. I m a 20 year old female. 5 feet tall, around 98 lbs. I eat a relatively normalhealthy diet. I don t eat a lot of fast food or anything. I ve actually been eating a gluten free diet for months hoping for relief. I do know I have severe allergies and several food allergies as well, including peanuts, soy, shellfish, and who knows what else. I was referred by my GP to go to both a Gastrointerologist and and allergist, but I was hoping maybe you could give me some insight on what may be wrong in the mean time.  <response>: HiP lease be more clear on why are you continuously taking macro bid for 6 months?? Macro bid is used to treat Urinary tract infection for a maximum period of 7-10 days. The green colored stools you are experiencing may be due to use of macro bid over a long period. It could be due to colitis caused by colostrum difficile. You need stop Caroline and take a course of pre-probiotics to improve intestinal flora. As far as NAFLD is concerned, you need to concentrate on losing weight, exercising and having a healthy diet rich in fruits and veggies
