1.] This disease was first discovered in the year 1932.
2.] Crohn’s disease is a chronic inflammatory bowel disease (IBD) characterized by inflammation of the digestive or gastrointestinal (GI) tract. It can affect any part of the GI tract, from the mouth to the anus, but it is more commonly found at the end of the small intestine (the ileum) where it joins the beginning of the large intestine (or colon). There is no known medical cure for Crohn’s disease. However, therapies are available that may greatly reduce the symptoms of Crohn’s disease and possibly bring about a long-term remission.
The signs and symptoms are from mild to severe and may develop gradually or come suddenly without warning.
- Abdominal pain and cramping
- Bloody stools
- Reduced appetite and weight loss
- Fever and fatigue
- Digestive tract problems
The inflammation in the walls of the digestive tract leads to pain, malabsorption of nutrients and poor osmosis so water stays in the digestive system causing diarrhoea. It also causes damage to the tissue in mucosal lining. The digestive system contains 70% of the immune system and provides a physical barrier against the outside world. It is selectively permeable, which means that only small particles of food and water should be able to pass through the walls. The damage to the walls is commonly known as “Leaky Gut”. When the substances that should not be in the blood stream are found by the immune system, which is on surveillance all the time, it mounts an attack on them. This is where antibodies may be created to new foods or substances. If the problem goes unchecked overtime the immune system becomes over alert and starts to attack the digestive tissues causes more inflammation and more leaky gut.
It involves drug therapy or surgery. Several drugs which control inflammation are anti-inflammatory drugs Sulfasalazine, Mesalamine and Corticosteroid.
- Immune system suppressors- Azathioprine and 6-mercaptopurine and infliximab works by neutralizing a protein produced by the immune system known as tumour necrosis factor (TNF). Ciclosporin and antibiotic Metronidazole is used to heal Crohn’s related fistulas.
- Other medication- Antidiarrheals relieve signs and symptoms of mild to moderate diarrhoea. Acetaminophen is used to for relieving pain.
- Iron supplements
- Vitamin B12 injections
