I want to see if anyone knows what's causing these symptoms; bloating from gas buildup, difficulty passing gas, constipation, urinating frequently, dr?

Hard to guess but...: If no bladder infection, then constipation or lactose intolerance could cause symptoms. A constipated person needs to be sure there is no disease causing it. If constipation is just due to slow movement of food and poop through the gut, then things to try are vegetables, water, prune juice, prunes, fiber+water (but excess fiber causes gas!), Miralax, (polyethylene glycol) Senokot, milk of magnesia, other laxatives...
