Hello, I have been having digestion problems for almost a month now and I'm getting fed up. It all started by me drinking a bottle of soda which had a funny taste, from that day till now i have rumbling sounds in my stomach and intestines, and diarrhea (not watery, rather loose and soft) and constipation at the same time. I've seen a doctor, snd she wants me to get tested for celiac disease and gluten intolerance, and suggested feces test too. The thing now is that I'm not sure about being gluten intolerant since we don't have it running in our family. Also, yesterday i finally used the restroom after 4 days of constipation, there was mucus in the stool and a tiny bit of blood. I'm confused and anxious at the same time, what could I be having. p.s: I'm taking medication that gets rid of diarrhea caused by bacteria, so i don't have diarrhea no more. And I've already done a regular blood test 2 months ago and it came back normal. Thanks for answering in advance !
