GERD is one of the most misdiagnosed conditions in this country and other countries. The symptoms associated with GERD are common in people that are over producing Hydrochloric acid (Hyperchlorhydria) and common in people that are not producing strong enough acid (Hypochlorhydria). Hypochlorhydria and Hyperchlorhydria will cause reflux, nausea, gas, belching, bloating, abdominal pain, gurgling, irregular stools, diarrhea and/or constipation, etc... The end result of the misdiagnosis, is that the patient is usually prescribed an acid reducing medication, or Proton Pump Inhibitor (PPI). When a person that is not producing strong enough acid is place on a proton pump inhibitor (PPI), he/she will develop Achlorhydria. Achlorhydria is the complete absence of hydrochloric acid, in the digestive process. There is no sterilization, or conversion, of the nutrients consumed. Hypochlorhydria and Achlorhydria will allow bacteria and pathogens to enter the small bowel, causing allergies and other serious conditions, not normally considers as allergies. Before taking any type of acid reducing medication for GERD, have your doctor give you an Heidelberg pH diagnostic test, or something similar, to find out exactly how your digestive systems is processing what you eat. Chances are, if you have GERD, you will not need an acid reducing medication, or PPI. There is a lot of information on the web, check out www.digestiveblog.com, or search for pH diagnostic test, pH capsule test, or pH gastrogram.
