What is the normal function of histamine in the stomach and how does it help hyperacidity?
Histamine in the stomach primarily stimulates the secretion of gastric acid by binding to H2 receptors on parietal cells, promoting the production of hydrochloric acid. This process aids digestion by breaking down food and activating digestive enzymes. In cases of hyperacidity, medications like H2 blockers can inhibit histamine's action, reducing acid production and alleviating symptoms such as heartburn and gastric discomfort. Thus, while histamine plays a crucial role in normal digestion, its modulation can help manage excessive acid levels.

What is the source and normal function of acid in the stomach and what regulates its production?
The primary source of acid in the stomach is parietal cells, which secrete hydrochloric acid (HCl). This acid plays a crucial role in the digestive process by breaking down food, activating digestive enzymes, and providing an acidic environment that helps kill harmful bacteria. The production of stomach acid is primarily regulated by the hormone gastrin, which is released in response to food intake, along with neural signals and other factors like histamine.
What are anti-histamines?
According to the Cleveland Clinic web site, "Antihistamines help relieve symptoms by blocking the action of histamine. Histamine is a naturally occurring substance that is released by the immune system after being exposed to an allergen. When you inhale an allergen, mast cells located in the nose and sinus membranes release histamine. Histamine then attaches to receptors on nearby blood vessels, causing them to enlarge (dilate). Histamine also binds to other receptors located in nasal tissues, causing redness, swelling, itching, and changes in the secretions. By blocking histamine receptors, antihistamines prevent symptoms" (Cleveland Clinic web site 11/10/2008). So in essence what is occurring is an antihistamine blocks the ability of the body's histamine to attach to the normal receptor to tell the body to have a runny nose, itchy eyes, swelling, etc. They do not inhibit the release of histamine, as this would affect a wide array of other vital body functions that rely on histamine to work properly (such as acid production in the stomach).
