### input:
I have been diagnosed with h pylori. I m on triple therapy. It s my third day of taking this therapy. Problem started with a stitch like pain in my left side waist. Had some painful gas over the next week and took GasX. One week ago I had such bad and painful trapped gas in my stomach that I thought I was having a heart attack! Could not stand up straight and felt nauseous. After one hour the GasX worked and I did numerous huge burps which got rid of it. Nice! Gas kept coming back though at random times daily for the next few days until I went to the doctor. I also have a gallstone and am worried that my symptoms maybe related to that rather than the h pylori. How long does triple therapy take to start symptom relief? Should I carry on taking all these meds or have testing to determine the root cause of my symptoms? I m taking 1000mg amoxicillin, 20mg omeprezole and 500g clarithromycin twice daily. I have diarrhea (started today), original pain in left side waist still, and intermittent gas/bloating. I woke up with gas/indegestion this morning. Thanks.

### output:

Hi I read carefully all your concerns, and I am so sorry for your situation. In regard to you symptoms it seems to be related with the start of triple therapy. Antibiotics that you are using have side effects like gas, bloating etc. The antibiotics change your normal microbial flora of intestine. Diarrhea is another side effect of antibiotics (amoxicillin, claritromicine) therapy at this situation I would recommend you to start probiotics, take plenty of water, take Tibetan and HY Chat Doctor. The side effects of antibiotics can start even after the first dose. If this is not enough please consult gastroenterologist and perform other exams like abdominal ultrasound(related to your gallstone), blood work, and fecal analysis. Hope it is helpful
