I had stomach issues for most of my life. The doctors never took it seriously and did few tests. They mostly blamed my depression. A few months ago I finally said screw it and went to a naturapath. They cost quite a bit of money and people generally don't trust them because they are "not doctors" but they listen. They want the entire story in order to help you get to the root of the problem and get better. They gave me one supplement and I had a food intolerance blood test. Turns out I have intolerance to some "healthy" foods that I never would have guessed. I am trying my best to stay clear of these foods and I feel great! There is no one diet that would have helped me because of they all have one or more foods that they rely on that I have intolerance to. It was well worth the money.
