Bloating/ gas constant over last month. diangosis gastroenteritis. still uncomfortable. could it be something more? ibs? celiac? taking lots of simethicone

Many causes: Abdominal bloating can have many causes including ibs, celiac, small bowel bacterial overgrowth, c. Difficile or other pathogen, lactose intolerance, gallstones, ovarian cancer, pancreatic problems, an obstructive problem w/ the colon, inflammation anywhere in the abdomen or urinary tract leading to an ileus(slow down in the contractility of the colon), etc..Go back to ur doc for a more thorough evaluation.

IBS is possible: Acute gastroenteritis (age) does not last one month. We often see post infectious irritable bowel syndrome following age, which can last weeks-months. Post infectious ibs is best treated with dietary adjustments. I recommend the low fodmap diet for 5 weeks. Celiac is uikely, but lab testing for this is quick and easy and should be done.
