I have a leaky gut and have started taking a
Probably the Benefiber
The most likely cause of the full, uncomfortable feeling is the Benefiber. Benefiber and Metamucil and other fiber supplements can cause this problem if not started at a very small amount and increased slowly. It takes the body awhile to get used to it.
Another possibility is the probiotic itself. Some of the probiotic microorganisms are meant to be in the large intestine only and can cause some distention when in the wrong place.
However, I am suspecting it's due to the Benefiber. Maybe back off of that a bit so that you can control all of the variables to see what is going on.
Let me know if I can assist you further.
