Many people, as they age, develop allergies that they never had when they were younger. The reason for this is a condition called Hypochlorhydria.
As the body ages the acid producing cell (parietal cells) in the stomach begin to wane in their ability to produce sufficiently strong hydrochloric acid (HCL). Hypochlorhydria is the reduction in the strength of the Hydrochloric acid in the stomach.
Strong HCL is absolutely necessary for breaking down, sterilizing and converting the food you eat. The HCL maintains a sterile environment in the stomach.
Normally, nutrients entering the stomach are sterilized and broken down into a thick liquid mass called chyme. Bacteria and pathogen are destroyed by the strong HCL. The peptic enzymes, with the help of the strong acid, break down proteins into peptones.
Many proteins are allergens and will cause allergic reactions, if they are not broken down, by the HCL and peptic enzymes. Once this pre-digestion process is complete the nutrients migrate into the small bowel where maximum absorption occurs.
Hypochlorhydria, reduced acid strength, does not breakdown the nutrients completely. There is less sterilization, and less conversion of proteins. The nutrients are prematurely dumped into the small bowel and there is less absorption of the necessary vitamins and minerals required to keep the body and immune system healthy. Hypochlorhydria causes malabsorption.
Proteins containing allergens are allow to enter the small bowel, resulting in allergic reactions. Skin allergy test will not be able to determine, if the allergic reaction is caused by unconverted proteins or by malabsorption.
The cause of incomplete sterilization, and conversion can be easily diagnosed, with one of the following type tests: a pH diagnostic test, pH capsule test, or pH gastrogram test. There is a lot more info in the web, check out www.digestiveblog.com.
