Gut issues

For the last year I’ve had problems with stomach gurgling, bloating, gas, brain fog, face puffiness, burping, not solid or consistently normal looking stools. I got a blood test and my vitamin levels were normal as well as my inflammation markers. Ive tried betaine hcl and digestive enzymes and ginger and artichoke but these don’t seem to help my digestion. I eat diversely with good fruits, veggies, fats, protein but try to stay away from dairy and gluten as much as possible but still have these symptoms. I’m wondering what could help in this situation or what are some possible root causes.
