A frequent occurrence of inflammation in the digestive tract can happen in some people. This is a form of inflammatory bowel disease. This disease is called Crohn’s disease. This is very discomforting and usually causes the digestive tract to swell up and irritates it. Crohn’s disease is a chronic illness. It causes major symptoms of discomfort in the digestive system of the patient. Starting from the mouth to the anus, any part of the digestive tract can get affected by it. Apart from just the digestive tract, it can also affect other parts of the body like the skin, bones, joints, and major organs like the liver, kidney, and eyes. This condition is also called an autoimmune-mediated inflammatory condition. 

Types and their symptoms

Now depending on which part of the digestive tract is affected by the disease, Crohn’s disease is further divided into various types. Each type has a specific region where the disease occurs and has specific symptoms associated with it. Even the treatment to be given for the suppression of the symptoms is based on the type of Crohn’s disease. Now let us have look at each type of Crohn’s disease.


The most common type of Crohn’s disease that affects the majority of people is Ileocolitis. In this type of condition, the inflammation and irritation take place in the last section of the small intestine. Mostly colon, the large intestine or the ileum, the lower part of the small intestine are affected by this. Some of the symptoms that you can except due to the development of this kind of Crohn’s disease are listed below.

  • Sudden and extreme weight loss in a short period of time.
  • Diarrhea
  • Aching in the abdomen, especially in the middle and the lower parts


When a patient with Crohn’s disease suffers from inflammation in the ileum, they are said to be affected by Ileitis. The symptoms suffered during this kind of the disease are almost the same as that of Ileocolitis. But one specific symptom that develops during this kind of the disease, is gastrointestinal fistulas. These fistulas are actually the pathways by the small intestine walls that produce inflammation. These channels act as a bridge or connecting path between the small intestine and the other body parts including the skin. Usually, through these inflammatory channels, digestive juices can leak out to surrounding tissues and organs and hence, resulting in various major health issues. Some of the complications associated with fistulas are dehydration, malnutrition, and extreme weight loss. 

Gastroduodenal Crohn’s

This is the kind of Crohn’s disease that occurs in the initial or first part of the small intestine. The major affected areas are the esophagus, stomach, and duodenum.

Some of the common symptoms found in the patients with jejunoileitis are mentioned below.

  • Intense abdominal pains
  • Severe  stomach cramps after every meal
  • Fistulas in the jejunum
  • Diarrhea

Crohn’s colitis

When the last part of the large intestine suffers from inflammation then the condition is called Crohn’s colitis. This occurs in the colon and hence is its name. Due to the development of this condition, there develops ulcers, fistulas, and abscesses around the anus and hence causing severe pain and discomfort. Some of the common symptoms of this disease include the

Besides these, your doctor may prescribe you certain dietary supplements. These are usually given when the patient is suffering from major malnourishment. This happens due to indigestion and inflammation in the digestive tract. So, to fulfill the nutritional needs of the patient, the doctor prescribes him some supplements.

Suggesting for surgery

This helps in reducing inflammation and discomfort, but it can’t treat the condition. Even after successful surgery, the condition may develop in nearby parts of the digestive tract. Usually, surgery is preferred as the last option while treating patients with Crohn’s disease. This is because firstly treatment with medicines and management methods is started. But when the condition worsens over time and fistulas, abscesses and hemorrhages start to develop and the discomfort rises manifolds, then the patient is made to undergo surgery.
