A chronic inflammatory bowel disease that affects the lining of the digestive tract. Crohn’s disease can sometimes cause life-threatening complications. Crohn’s disease can cause abdominal pain, diarrhoea, weight loss, anaemia and fatigue. Some people may be symptom-free most of their lives, while others can have severe chronic symptoms that never go away. Crohn’s disease cannot be cured. Medications such as steroids and immunosuppressants are used to slow the progression of disease. If these aren’t effective, a patient may require surgery. Additionally, patients with Crohn’s disease may need to receive regular screening for colorectal cancer due to increased risk.
