Overview

A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. A compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and the particular organism. For example, ascorbic acid functions as vitamin C for some animals but not others, and vitamins D and K are required in the human diet only in certain circumstances.

Vitamins are classified by their biological and chemical activity, not their structure. Thus, each "vitamin" actually refers to a number of vitamer compounds, which form a set of distinct chemical compounds that show the biological activity of a particular vitamin. Such a set of chemicals are grouped under an alphabetized vitamin "generic descriptor" title, such as "vitamin A," which (for example) includes retinal, retinol, and many carotenoids. Vitamers are often inter-convertible in the body. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but are otherwise required less often.

Heartburn is Most Common After Overeating

Heartburn is not a malfunction, but the heart results nervous tension or overindulgence in food or drink. The sensation is of spasmodic narrowing of the esophagus or accompanied by the regurgitation of stomach acids, which are top in the neck, and can cause regurgitation or vomiting. Heartburn is an unpleasant, but the feeling of warmth or burning in the chest. Although the pain of heartburn is also in the chest, heartburn has nothing to do with the heart. The spectrum of diseases associated with GERD and reflux esophagitis, Barrett's esophagus and nonerosive reflux disease.

It is due to acid reflux disease needs strong heartburn medication. Instead of a searing pain, some people have a sour taste in the throat (acid regurgitation). Heartburn occurs when the acid contents of the stomach pass back into the esophagus (called the esophagus, or gullet). This is also known as stomach acid reflux.

It is also one of the causes of chronic cough, and can even mimic asthma. Despite its name, heartburn actually has nothing to do with the heart. It has nothing to do with the heart. It occurs when acid from the stomach regurgitates, or back in the lower esophagus, the tube connecting the mouth and stomach.

pregnancy, stress and certain foods can also worsen heartburn. There is even during pregnancy, with about 1 in 4 women reporting it daily at some point during their pregnancy. Statistics on acid indigestion are hard to find, because the definition is vague, but it is probably almost as often as heartburn. It happens when acid has been in the wrong direction, since it makes the esophagus into the stomach instead.

eating smaller meals, controlling your weight, avoid tight-fitting clothing, and avoiding heavy lifting /debited are all possibilities for reducing heartburn. Do not lie down after meals, because that makes it easier for stomach contents (including acid) to back into the esophagus.
