I am discovering that I may have low stomach acid, a condition called Hypochlorydia. It can be very dangerous to your help over time. I now have a pacemaker, and a hypothyroid condition so I am on natural antithyroid medicine, Naturethroid. My father always complained of stomach problems and was never diagnosed of anything which is normally what happens today with traditional ALLOPATHIC(chemical based) doctors. They are the one 150 years ago that claimed their gadgets healed and many died. Today they do not treat you but give pills. If you do not research and think for yourself then you will not survive. Search until you find a doctor that will give you a test kit or something to find out if you have parasites. Best wishes and persevere.
