So the backstory is that I need to gain a few pounds because I'm underweight right now and really lacking in energy. The problem is that my digestive system is "bad". I get a lot of stomach pain, constipation/diarrhea, indigestion, gas and bloating (sorry TMI). I've had the investigation where they put a camera down your throat before, and nothing was ever found. Plus its not a new condition, I've been like it my whole life, though its definitely gotten worse in the last few years. I would say my diet is mostly healthy though I do drink too much coffee. I very very rarely drink alcohol nowadays, simply because the stomach pain isn't worth it!
So my next avenue to try is probiotics. They're expensive, particularly if you stay on them, but if they give relief I'm willing to throw money at the problem. Can anyone reccomend any? (or conversely, are they a waste of money in your opinion?)
