bloat after fasting is always inefficient digestion which is the main reason why fasters re-feed *very slowly*. bloat is also the main symptom people with irritable bowel syndrome have IF they persist in eating foods their stomach doesn't make the right amount or type of digestive enzymes for. to make matters worse, the walls of the small intestine and large intestine have hypersensitive nerve cells that send excruciating pain signals thru the CNS (central nervous system) whenever there is any undue pressure, like gas, in there and the pain signals don't quit, till it's OUT. good luck.
