An anal fissure is a minute split which looks like a paper cut in the inside layer of the anus. A solid, dried up bowel movement can result in the rupture in the lining. However, attacks of diarrhoea, childbirth and mistreatment of laxatives may also lead to such fissures.

A fistula is a minute canal that builds up in the occurrence of inflammation and illness. It may or may not be linked with an abscess, but similar to abscesses, some illnesses such as Crohn's disease can develop fistulas.

Colon cancer begins as a polyp which is a developed in the lining of colon. If these polyps can be noticed before time and separated then colon cancer can be effortlessly be prevented.

Crohn's disease is a chronic, recurring inflammatory infection of the intestinal tract. The two most important sites for Crohn's disease are the ileum that is the final segment of the small bowel and the colon (Crohn's colitis). The inside layer of the bowel can become swollen, ulcerated and the bowel wall gets condense. Ultimately, the bowel may become lessened or blocked.

The gallbladder preserves and concentrates the bile formed by the liver and discharges into intestine when required for digestion. Bile is made up of a mixture of chemicals with cholesterol, salts, and particular pigments. In few people, small crystals form from the cholesterol and pigment which eventfully turn into big gall stones.

Lactose intolerance takes place when the body has intricacy absorbing and digesting whole and skimmed milk and other dairy products. Lactose is a milk sugar and similar to most of the sugars, it is broken down by enzymes in the intestinal tract so it can be absorbed as a source for energy. The enzyme that breaks down lactose is called as lactase. When the intestine does not holds lactase, and then lactose intolerance can happen. It is a bothersome and irritating problem, but it is never a severe one.

When ulcers or sores build up in stomach or duodenum (in the starting of intestine), is known as peptic ulcer disease (PUD. The stomach generates a very strong acid. This acid assists in digesting and breaking down food previous to it enters the small intestine. The lining of the stomach is enclosed by a wide protecting mucous layer which stops the acid from damaging the wall of the stomach. When this mucous blockade is prevailed over by the acid or bacteria such as H. pylori or medications such as aspirin or parallel non steroidal anti-inflammatory drugs (NSAIDS), ulcers build up in stomach or duodenum. Ulcers also increase in tumours such as gastrinomas when patients develop huge quantity of acid...

The immune system comprises of diverse forms of white blood cells that help out to fight infections. Several of these cells create antibodies. Antibodies act as fighters. They protect the body by wiping out bacteria, viruses and other unfamiliar materials. There are different types of antibodies, each combating against a precise foreign material. Therefore, the immune system defends the body against external attack by germs. But occasionally, the immune system wrongly recognizes the body's own organs as unfamiliar. It can build up antibodies against these organs. This can cause various illnesses, such as rheumatoid arthritis and lupus. These illnesses are called as autoimmune disorders because the body is exactly struggling against itself.

When the immune system attacks the liver in this way, it is described as autoimmune hepatitis. Autoimmune hepatitis is not originated by a virus or bacteria, so it is not a infectious disease. Precisely what start the immune system against the liver is unidentified. The inflammation is typically chronic, and with no treatment it can cause severe damage to the liver.

Numerous kinds of chronic injuries to the liver can effect in scar tissue. This scarring deforms the usual structure and regrowth of liver cells. The blood flow through the liver from the intestine is blocked-up and the work done by the liver, such as dealing out drugs or manufacturing proteins, is delayed.
