Crohn’s disease, also known as ileitis or enteritis is a long-term inflammatory bowel disease (IBD) that causes inflammation in the lining of the digestive system. This disease can affect any part of the gastrointestinal tract, comprising of the mouth, oesophagus, stomach, small and large intestines, and anus. In majority of the people, however, the lower part of the small intestine, i.e. the ileum, is affected.
This inflammatory bowel disease should not be confused with Irritable Bowel Syndrome (IBS).
The damaging inflammation of Crohn’s may cause abdominal pain, frequent diarrhoea and other symptoms which vary from mild to severe. In certain cases, it can also be life-threatening.
In Crohn’s disease, the immune system of the body attacks the harmless or the good virus, bacteria, or food in the gut that causes inflammation leading to bowel injury.
Since the immune system is involved, Crohn’s is medically classified as an autoimmune disorder. It has not been substantiated as to why the immune system suddenly begins to attack the gut bacteria, and the food. Due to the attack white blood cells accumulate in the lining of the gut, which triggers inflammation. This inflammation leads to ulcerations and bowel injury.
Since the exact cause of the malfunctioning immune system has not yet been found, scientists now believe that genetic factors may contribute in causing this disease. Furthermore, links have been discovered between this disease and mutations in genes located on chromosomes 5 and 10. These genetic variants affect the bacteria in the digestive system. Changes in the gut bacteria can cause the intestinal cells to respond to it abnormally, which in turn can cause inflammation and digestive issues that are associated with Crohn’s disease.
Though the exact causes of Crohn’s disease are not known, researchers believe a number of factors can contribute to this disease such as:
Some people are more prone to Crohn’s disease than others, such as:
The symptoms of Crohn’s disease include:

The complications of Crohn’s disease include:
There is currently no cure for Crohn's disease, and there is no one treatment that works for everyone. The goal of the treatment is to reduce your symptoms.
Your doctor can prescribe anti-inflammatory drugs, immune system suppressors, antibiotics, pain relievers, antidiarrheals, and vitamin supplements. In severe cases, the doctor may prescribe nutrition therapy, (wherein a special diet given via a feeding tube, or nutrients injected into a vein to treat your Crohn's disease), and also surgery.
India has over 12 lakh cases of 'inflammatory bowel disease' or IBD annually but very few people are even aware of the seriousness and symptoms of the disease.
About 50 lakh people have IBD across the world.
