What is Crohn’s Disease?


Chron’s Disease, Types, and Symptoms

Crohn’s disease is a chronic disease of inflammation that affects the bowel or gastrointestinal tract. It falls under the group of inflammatory bowel diseases (IBD).

Chron’s disease is known to cause inflammation of the digestive tract. This disease can result in abdominal pain, fatigue, severe diarrhea, loss of weight, and malnutrition. The inflammation that it causes may vary in different people’s digestive tract areas and usually goes deep into the affected bowel tissue’s layers.

Crohn’s disease can be severe and sometimes may result in deadly complications. Sadly, it has no known cure; however, therapies can significantly lessen the signs and symptoms, as well as help patients achieve long-term relief.

Types of Crohn’s Disease

While different patients may experience varied symptoms of Crohn’s disease, the symptoms you may experience depends on the Crohn’s disease type you have.


Ileocolitis is the most prevalent type of Crohn’s disease. It affects the terminal ileum (end of the small intestine) and the colon (large intestine). Common symptoms include diarrhea and cramping, pain in the middle or lower region of the abdomen, and weight loss.


This form of Crohn’s disease affects the ileum alone. Patients may experience similar symptoms as with Ileocolitis.

Gastroduodenal Crohn’s Disease

This type affects the stomach and the duodenum (beginning of the small intestine). Vomiting, nausea, loss of appetite, and weight loss are common symptoms.


Patchy areas of inflammation in the jejunum (upper half of the small intestine) identify with this type of Chron’s disease. Symptoms may include mild to severe stomach pain, diarrhea, and cramping after meals.

Crohn’s (Granulomatous) Colitis

This type affects only the colon (large intestine). Symptoms may include diarrhea, rectal bleeding, anal cracks, abscess, ulcers, skin lesions, and joint pains.

Symptoms of Chron’s Disease

The effect of Crohn’s disease may slightly vary in different patients. But with this post, we’ll highlight the most common signs and symptoms. The symptoms experienced by a patient depend on the part of the affected gastrointestinal tract.

The chronic nature of Crohn’s disease means that patients are likely to experience flares periods (when symptoms are active), followed by remission periods (when you may not feel any symptoms at all).

While recognizing the signs of Crohn’s disease is essential, only a qualified doctor can confirm a diagnosis. Thus if you suspect you may have IBD, it is advisable to meet with your doctor for diagnosis and treatment plan.
