Crohn’s disease and ulcerative colitis don’t just affect the bowels. Ahead of World IBD Day on May 19, gut health blogger Jenna Farmer highlights some of the less obvious effects of these conditions

WHAT springs to mind when you hear the words inflammatory bowel disease or IBD? Dodgy bellies, toilet troubles? The two most common forms of IBD are Crohn's disease and ulcerative colitis. Yes, both are digestive conditions, but there's a lot more to them than that.

About 300,000 people in the UK are known to be living with IBD, though the actual figure is believed to be much higher; it can take years to get a proper diagnosis for these types of conditions because symptoms can be vague and similar to more common problems, such as irritable bowel syndrome, and lots of people could be suffering in silence. Lifestyle and dietary changes, along with medication, can help manage the disease and reduce inflammation, but sometimes surgery's required.

Jenna Farmer was diagnosed with Crohn's disease in 2012 and is now a nutritional therapist who writes about gut health on her blog, A Balanced Belly ( She recently published her first book, Managing IBD: A Balanced Guide To Inflammatory Bowel Disease, in which she points out that symptoms of these conditions can extend far beyond the bowels.

Here, she shares nine symptoms you might not be aware can be linked to IBD.

1. Eye inflammation. IBD can affect all parts of the body, even our eyes. Episcleritis is the most common eye condition for those with IBD. It affects the layer of tissue that covers the white outer coating of our eyes and causes it to become inflamed and sore.

2. Erythema nodosum. This is a sore and painful skin condition that causes painful lumps on the arms and legs. It's estimated up to 10% of those with ulcerative colitis and up to 15% of those with Crohn's disease may experience this.

3. Loss of menstrual cycle. Women with IBD may suffer from irregular cycles or the absence of periods altogether. This is thought to be due to various factors, such as nutritional deficiencies, disease activity or weight loss.

4. Night sweats. This is often worse during flare-ups and can also be the side effect of several medications prescribed for IBD.

5. Constipation. We always associated diarrhoea as a classic IBD symptom, but many patients can suffer from constipation, too. This is usually due to inflammation or an obstruction.

6. Fatigue. Crohn's and Colitis UK estimate that up to 75 per cent of IBD patients struggle with fatigue and many complain about constantly low energy levels. Fatigue often improves when patients are in remission, but some find it never goes away completely.

7. Vitamin D deficiency. It's well known that those with IBD may be low in iron and B12, but it's likely they'll suffer with low vitamin D levels, too. Recent research suggests about 30 per cent of people with IBD are also deficient in the sunshine vitamin.

8. Joint pain. Inflammation of the joints is a common complication of IBD. It's estimated one in three patients experience it and symptoms are often worse during a flare-up.

9. Mouth ulcers. These are another common symptom and the first obvious sign of IBD in some individuals.

Mental health awareness

With about one in four people in the UK experiencing mental health problems each year - and many more feeling the effects of stressful workloads and ever-demanding 'modern lives' - it's little wonder that in a recent poll, 97 per cent of people said they know someone who's suffered from a mental health condition. Nightingale Hospital, London's leading private mental health hospital, polled 200 members of the general public, but the findings suggest there's still some way to go to raise awareness and ensure everybody has access to mental health support. Some 39 per cent also said they wouldn't know how or where to access mental health treatment, and 92 per cent think there needs to be more information on how to access mental health services.
