This is correct but for those like myself who were checked and no answer was found, try a lifestyle change...diet, exercise, yoga as someone mentioned above. And as I've said repeatedly research everything...some diets aren't good for the body...ie low carb, high protein ( which are highly acidic and hard on the organs and can also trigger a potassium deficiency) etc.

We've been conditioned to eat to satisfy hunger but in actuality we eat to fuel the body's millions of metabolic processes. It requires certain nutrients to do an efficient job. Whatever the issue, I don't think you could ever go wrong by eating more vegetables, less meat, small quantities of fruit... maybe even a little egg, milk and cheese for vitamins AD&K, if your body responds favorably. Listen to what's right for you.
