Misdiagnosis and a lack of understanding around how to diagnose microscopic colitis may lead to underreporting, with many people remaining undiagnosed. Symptoms can include severe watery diarrhea, nocturnal symptoms, and unpredictable flare-ups. Effective treatment is available, however, diagnosis rates need to improve.

Are you experiencing chronic diarrhea and abdominal pain? You may be wondering if you have microscopic colitis. Microscopic colitis is a type of inflammation that affects the colon and it is becoming increasingly common. In this article, we will explore what microscopic colitis is, its symptoms, and its causes. We will also look at who is at risk for developing this condition and how it is diagnosed and treated.


Microscopic colitis, an inflammatory bowel disease that affects around 17,000 people in the UK each year, may be vastly underdiagnosed due to difficulties in detecting the condition, according to Guts UK. Unlike other inflammatory bowel diseases, microscopic colitis is not visible on a camera and requires a tissue sample. Guts UK says many patients are left without a diagnosis, and misdiagnosis with irritable bowel syndrome (IBS) is common. Once diagnosed, however, the condition can be treated effectively. Symptoms of the disease include severe watery diarrhea, nocturnal symptoms such as waking up needing to open bowels, unpredictability of flare-ups and anxiety around incontinence. Fatigue, nausea, stomach cramps and weight loss can also occur. The disease is not fully understood, but an interplay of genetics, immunological factors and the microbiome is suspected. People with coeliac disease and autoimmune diseases are more likely to develop it. Though microscopic colitis is not directly associated with life-threatening complications, symptoms can be severely debilitating with impacts felt across work, social lives, relationships and mental wellbeing. The rates of microscopic colitis are increasing, particularly among aging populations, and Guts UK is calling for greater awareness, investment and research into diagnosis and treatment. Chris Probert of the University of Liverpool warns that undiagnosed microscopic colitis can lead to years of unnecessary suffering, but that effective treatments are available.


In conclusion, microscopic colitis is a lesser-known condition that can cause severe discomfort for those who have it. It is often overlooked due to its similar symptoms to other digestive conditions, but it is vital to get a proper diagnosis to receive effective treatment. If you are experiencing chronic diarrhea, abdominal pain, and weight loss, it’s essential to talk to your doctor about the possibility of microscopic colitis. With proper diagnosis and treatment, it is possible to manage the symptoms and improve your quality of life. Remember, if you suspect you may have microscopic colitis, don’t hesitate to seek medical attention. Taking care of your digestive health is important, and knowing what to look out for can help you get the treatment you need.
