Hi I often have gas in my stomach what causes this? And how can I get rid of it it makes stupid noises

Food intolerance. Excess gas can be a sign your body is having difficulty digesting what you ate. This can be genetic; lactose is a common food intolerance. It can also be related to an imbalance of the bacteria in your gut, so I usually recommend taking some probiotics for a few weeks to see if symptoms improve. If your symptoms include weight loss, bleeding in GI tract or pain, get full workup right away.
