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.

Digestive System Disorders

The function of the digestive system is the living and fluids, which we put in our mouths and then either in the energy and nutrients needed, the cells of our body, turning what the body does not absorb the waste products to be expelled from our body as chair. Disorders of the gastrointestinal system happen if there is a faulty during the digestive function prevents the part of the digestive system from functioning as it should. There are many common digestive system and Rectal disorders.

Colon cancer is a malignant cell in large bowel, which consists of the colon and rectum. Colon and rectum cancer types shares so many common features that they like cancer, the same as the name of colon cancer came from. Colorectal cancer is the second leading cause of death by cancer in the United States, if you experience symptoms of colon cancer, you should ask your doctor immediately.

Stomach cancer, stomach cancer or concerned about 21700 Americans in the 60s and 70s in 2001. The risk factors for the development of gastric cancer, a diet consists of eating that large quantities of food, smoked, salted fish and meat, food, the high and low in fiber strength, pickled vegetables, and food and beverage industry, the nitrates and Nitrites .

diarrhea, or watery stool is an increased frequency in the faeces, or both, compared to the normal amount of stool by the individual. Diarrhoea can short-term, which is associated with a bacterial or viral infection, or it may be long term, which are usually associated with a functional bowel disorder or disease.

Diverticulitis is an inflammation or infection occurs in small bags, the camber in the colon. There is a tendency for these patches to catch and trap foods particles, which can cause infection.

Gas in your stomach and intestinal content is often caused by air or swallowing complaints during the process of allocating certain foods by the bacteria, in the colon. Everyone has gas, but if you have a gas problem can certainly be unpleasant and embarrassing that the gas.

Heartburn is what most of us from time to time. Chronic heartburn problem is a digestive disorder called gastro-intestinal tract oesophagus reflux disease (GERD). GERD is supported by stomach acid, from the back and stomach into the esophagus, where it can burn delicate tissues, and can cause cancer.

There are different diseases under the category of Inflammatory Bowel Disease (IBD), all, The one doctor for treatment. Ulcerative colitis and Crohns disease are two of these diseases. Ulcerative colitis can be difficult to diagnose because the symptoms are similar to other intestinal disorders and Crohns disease. Crohns disease is different because it deeper causes inflammation in the intestinal wall and can occur in other parts of the digestive system, including the small intestine, mouth, esophagus and stomach. Crohns disease symptoms can be different for each person. The most common symptoms of Crohns disease are abdominal pain and diarrhea. Some people have bleeding in the rectum, which is at the lower end of the GI tract, just before the anus, which is serious and can not stop without medical help. Bleeding can lead to anemia, the loss of too many red blood cells. Anemia is a person to feel tired. You can also weight loss, skin problems and fever. Children with Crohns disease develop and grow slower than most other children, or they can not expect to reach its full height.

Irritable bowel syndrome (IBS, spastic colon, irritable colon, nervous or stomach) is a condition in which the colon muscle contracts lighter than for people without IBS. A number of factors can lead to IBS, including certain foods, medicines and emotional stress. Symptoms of IBS, abdominal pain and cramps, excess gas, bloating, and a change in bowel habits, such as severe illnesses, easier, or more urgent than normal stool. Often people with IBS alternating constipation and diarrhea. The primary causes of IBS: Eating a diet low in fiber, not drink enough water or other fluids, not enough movement, travel or other changes in routine, eating large quantities of milk products, stresses resisting the urge to have stools that a laxative that, over time, weaken the intestinal muscles, the medicines antacids, calcium or aluminum, under certain medications (especially antidepressants, iron pills, medicines and narcotic pain), and intolerance is a pregnancy.

Lactose a condition caused by the lack of an enzyme lactase, which is necessary for the body to digest lactose (sugar in milk products). Adults and children can be affected by this intolerance. Gastro-intestinal illnesses or injuries to the small intestine can lead to such intolerance. Individuals can be different symptoms, but the common are: cramps, bloating, gas, diarrhea and nausea. The symptoms worsen when dairy products are consumed.

Stomach ulcers or stomach ulcers, duodenal ulcers, open wounds or skin changes in the mucous membranes of areas of the body. Lifestyle, diet and stress may play a role in the formation ulcer, but they are unlikely to lead to the most important of them. Scientists now know that ulcers are hydrochloric acid and pepsin, which in our stomach and duodenum parts of our system and digestive acids that contribute to ulcer formation, many stomach ulcers are caused by the bacterium H. pylori, and can be cured Antibiotics.

Constipation is difficult with the passage of the chairs or the rare (less than three times per week) or incomplete passage of the chairs. Constipation is usually insufficient roughage, or glass fiber in the diet or an interruption of regelmaigen routine or diet. Constipation leads to a person in charges for a bowel movement. It sometimes causes problems, such as anal fissures and hemorrhoids. The body needs two kinds of fiber: soluble fiber (dissolves and acts like a sponge) and insoluble (not dissolve and acts like a wisk brooms). We have recently identified the need for a third type of fiber, macrofiber; macrofiber is not only insoluble, it is indigestible, and it carries water through the digestive tract with your food. We are still many macrofiber 100 years old, and we called it chaff, and a bit of dirt from the garden, and bug parts ....

Structural diseases are those in which the intestine is abnormal and does not function properly. Sometimes, the structural anomaly must be surgically removed. The most common diseases are the structural impact on the anus, and Diverticulitis and cancer.

Hemorrhoids are swollen Blutgefae the anal opening, through the exertion of pressure on a stool, persistent diarrhea or pregnancy. There are two kinds of hemorrhoids: internal and external. Internal hemorrhoids are normal structures cushioning the lower rectum and protects them from damage caused by stool. If they are not in the anus as a consequence of the burden, they are irritated and start to bleed. Ultimately, the internal hemorrhoids may fall enough to sink or protrude from the anus. External hemorrhoids are veins, which is just under the skin on the outside of the anus. Sometimes, after the effort, the external hemorrhoidal veins burst and a blood clot forms in the skin. This condition is very painful than pile.

Anal cracks are splits or cracks in the lining of the anal opening. The most common reason for an anal column is the transition from very hard or watery stools. The crack in the lining anal exposes the underlying muscles, the passage of stool through the anus and from the body. An anal column is one of the most painful problems exposed because the muscles are irritated from exposure to stool or in the air, and leads to intense burning pain, bleeding or bowel spasm after movements.

Colitis is a condition, an inflammation of the intestine. There are several species, including the infectious colitis (caused by bacteria), ischemic colitis (caused by inadequate blood supply to the colon), colitis radiation (radiation therapy), ulcerative colitis (cause unknown), and Crohns disease (CAUSE not known). Colitis causes diarrhea, rectal bleeding, abdominal cramps, and urgency (frequent and immediate need for the empty intestine) .

Celiac disease is a prerequisite for the intolerance to gluten, a protein in wheat, rye, barley, and in some medicines. In people with celiac disease, the body's immune system reacts to gluten by attacking and damaging the lining of the small intestine. Eating foods containing gluten can be severe abdominal pain. When the lining is damaged, the body does not need the nutrients. Over time, celiac disease can cause anemia, infertility, the bones weak and brittle, and other health problems. Celiac disease is usually run families.

Rapid gastric emptying or dumping syndrome, occurs when undigested food empties too quickly into the small intestine. Early rapid gastric emptying begin either during or immediately after a meal. The symptoms can be nausea, vomiting, bloating, cramps, diarrhea, dizziness and fatigue. Late rapid gastric emptying is 1 to 3 hours after meals. Symptoms include hypoglycemia, low blood sugar, weakness, sweating and dizziness. Experience both forms of gastric emptying is not uncommon.

Smoking may harm all parts of the digestive system, contributing to such common disorders as heartburn and stomach ulcers. Smoking increases the risk of Crohns disease and possibly gallstones, which form when liquid in the gall bladder stored and hardens into pieces of stone-like material. Smoking also damages the liver.

Many diseases of the colon and rectum cancer can be prevented or minimized by a healthy way of life and to practice good nutrition, exercise, and bowel habits:
