You can actually have a serious medical condition that may lead to Diverticulitis, which will then lead to other issues. At least you are letting the gas out, which is a good sign.
I suggest seeking medical attention and logging your diet, including alcoholic beverages. Bacterial growth in the intestine is normal, but if there is an imbalance you may be harvesting a yeast farm, which will also produce more gasses.
Good luck, anon.
