Anti-Histamine Interference on the Digestive Process

There are two types of antihistamines they are H1-receptor (Histamine) antagonists and H2-receptor antagonist. Both of these antihistamines prevent the release of Histamine. Histamine is a hormone that is released by the body when an allergic reaction occurs. Histamine stimulates the release of gastric secretions, to counteract allergens that enter the body, dilates blood vessels, and contracts smooth muscles. Antihistamines stop the stomachs parietal cell from producing sufficiently strong Hydrochloric acid (HCL). HCL is absolutely necessary in maintaining a sterile environment in the stomach, neutralizing bacteria, pathogens, and fungus that may enter the stomach with nutrients. HCL is also responsible for breaking down and converting proteins into proteoses and peptones, the building blocks for the amino acids. Many proteins are allergens and will cause allergic reactions, if they are not broken down and converted by the HCL and peptic enzymes. Antihistamines will affect the natural pH balance of the digestive process.
