What Are Different Types of Colitis?

Colitis is caused by inflammation of colon and there are several different types of this disease.

Inflammatory bowel disease (IBD) – is a group of inflammatory conditions of colon and small intestine and are considered as autoimmune disease, in which the body’s own immune system attacks portions of digestive tract.  There are two major types of IBD:

  • Ulcerative colitis – typically affects just the innermost lining of your large intestine (colon) and rectum. It takes place just through continuous stretches of your colon.   Ulcerative colitis may be incapacitating and in some cases can result in life-threatening complications. It is a chronic illness so symptoms usually progress gradually, instead of suddenly. There isn’t any known cure for ulcerative colitis, however there are treatments  that could significantly lower the symptoms and perhaps result in a long-term remission.  Click here to learn more about Ulcerative colitis.
  • Crohn’s disease – type that often leads to Colitis and it can happen anywhere in the digestive tract and often spreads deeply into the affected tissues.

Microscopic colitis – inflammation of the colon that triggers prolonged watery diarrhea. The condition is diagnosed by microscopic study of colonic tissue and that is how it gets its name.  There are 2 types of microscopic colitis:

  • Collagenous colitis – Thick coating of protein (collagen) develops in the walls of colon.
  • Lymphocytic colitis –  lymphocytes (type of white blood cells) accumulates in the layers of the wall of colon.

It isn’t known whether collagenous & lymphocytic colitis are two distinct conditions or different levels of the identical illness. Nonetheless, signs and symptoms of both are the same as well as testing and treatment.

Ischemic colitis – the symptoms of microscopic colitis may appear and go frequently. Sometimes the symptoms clear up automatically.  Otherwise, there are number of drugs and medications that can be effective in treating this type of colitis.

Ischemic colitis happens blood circulation to section of the colon is decreased because of narrowed or clogged arteries. The reduced blood flow supplies inadequate oxygen for the cells in the digestive tract. It may cause discomfort and can harm your intestinal tract. Ischemic colitis can impact any area of the colon, but many experience pain on the left side of the abdomen.

Ischemic colitis is most typical among people over the age of 60. It may be wrongly diagnosed since it could be mistaken for other gastrointestinal conditions. Ischemic colitis may heal by itself.  However you may require medicine to address or avoid infection, or surgery in case your colon has been damaged.   For more information click here.

Pseudomembranous colitis – This happens in some individuals who have taken antibiotics and is almost always connected with overgrowth of bacteria called Clostridium Difficile also know as C. Diff.    C. Diff is the bacteria that causes colitis and happens when a person takes antibiotics or is hospitalized.  It is found in the large intestine and exists with other regular harmless bacteria.  Once the antibiotic is taken and vulnerable bacteria are eliminated, the C. Diff over grows and causes colitis.  C. Diff also exists in many areas of hospitals and it is contagious.  Because of the spread of this bacteria, people can also get this type of colitis without taking any antibiotics or being in a hospital or clinics.
