I've had digestive problems since I was younger. It was not until recently (I am in my 20s) that these problems became quite severe: acid reflux, severe indigestion (food feeling like it was not even going into my stomach), heart burn (burning in my stomach as well), and stomach pain that transfers to the lumbar region of my back (which then makes it impossible to stand up) along with other symptoms due to lack of nutrition (fatigue, lack of focus, bloating, diarrhea, etc).
After a trip to the doctor, I realized that these symptoms were due to food intolerances and quickly reduced my diet to three things: yogurt, eggs and bread. While I am able to digest these, if I snack in between meals or eat too much at once (where too much, is actually too little), then I experience severe pains due to digestion problems as well as weight gain.
At one point I reduced my diet to just bread, crackers and soup. I lost around 15 pounds within a few weeks and barely experienced any digestion problems. So I have a feeling that this is what my diet must consist of from now on - since anything else I've tried increases my digestion problems.
Anyone else have these sorts of problems? And how do you deal with them? My doctor said that he's never heard of the stomach pain transfering to the back - however I've had this since I was in high school. Has anyone else heard of this?
