Iron Supplementation for Inflammatory bowel disease
Inflammatory bowel disease (IBD) is the name for a group of chronic conditions where sections of your gastrointestinal tract becomes inflamed.
The two most common forms of IBD are Crohn’s disease and ulcerative colitis. 1 If you have IBD, your risk of also having iron deficiency (ID) and iron deficiency anaemia (IDA) increases.2
In patients with IBD, 36-76 % experience IDA.3 The main reasons why you may experience ID or IDA with IBD are:1
Anaemia is a frequently occurring problem in patients with IBD, and IDA is the most common cause. 1 Other causes of anaemia in IBD patients include:1
- Anaemia of chronic disease (inflammation)
- Anaemia due to decreased absorption of Vitamin B12 and folate in inflamed regions of the gastrointestinal tract
- Drug-induced anaemia
Anaemia affects the majority of patients with IBD, with the average IBD patient being anaemic one out of every five months. 4 It is important that anaemia, whether due to ID or any of the other reasons mentioned, is treated. ID can lead to a reduced work capacity, and if symptoms are severe, can cause an extended hospital stay. 2 If you think you may have signs of ID, it is important that you talk to your doctor.
