World IBD Day is the international day of awareness for Crohn's and ulcerative colitis, taking place each year on 19 May.
It exists to give visibility to one of the most misunderstood chronic illnesses in modern medicine, an illness that affects around 10 million people worldwide and more than 500,000 in the UK alone.
I'm Manny, and I was diagnosed with Crohn's at age 11. For 16 years it shaped every part of my life.
World IBD Day matters to me because it forces a conversation most people would rather avoid, and for one day a year, those of us living with the illness are seen.
In this article you will learn what World IBD Day is, what the 2026 theme means, the difference between Crohn's and ulcerative colitis, the reality of living with IBD, and how you can show support.
What Is World IBD Day?
World IBD Day is the international awareness day for people living with inflammatory bowel disease, and it happens every year on 19 May.
It was launched in 2010 and is coordinated internationally by the European Federation of Crohn's and Ulcerative Colitis Associations (EFCCA). The campaign now reaches more than 50 countries across five continents.
The official colour is purple. Wearing it on 19 May is a way of saying to anyone living with Crohn's or colitis, "I see you, and you are not alone."
2026 Theme: IBD Has No Borders
The 2026 theme for World IBD Day is "IBD Has No Borders: Access to IBD Care."
The focus this year is on the inequality of diagnosis, specialist treatment, and ongoing support across different countries and regions. IBD does not discriminate by country, income, or culture. The care a patient receives often does.
In some regions there are no IBD specialists at all, and biologic medications are unaffordable. Even within the UK, access varies between regions, and diagnostic delays of several years remain common.
The NHS does brilliant work, and I owe my own life to the surgical team that operated on me on Christmas Day 2016. Waiting lists, specialist nurse shortages, and postcode lotteries are real barriers that this year's theme aims to address.
Understanding Inflammatory Bowel Disease
IBD is an umbrella term for chronic autoimmune conditions that cause inflammation in the digestive tract. The immune system mistakenly attacks the lining of the gut, leading to ulcers, bleeding, pain, and disruption to digestion.
IBD is lifelong, and it differs from IBS, which is a functional disorder rather than an inflammatory one.
Crohn's disease
Crohn's can affect any part of the digestive tract, from the mouth to the anus, though it most often shows up in the small intestine. It causes inflammation through the full thickness of the bowel wall, which is why complications like strictures, fistulas, and perforations are common.
Symptoms include abdominal pain, diarrhoea, fatigue, and weight loss. In my case it stunted my growth, kept me out of school, and eventually perforated my bowel.
Ulcerative colitis
Ulcerative colitis is limited to the large intestine and rectum. It affects only the innermost lining of the bowel and is continuous rather than patchy.
Common symptoms include bloody diarrhoea, urgent bowel movements, cramping, and tiredness. Flares can be severe enough to require hospitalisation, though remission can also last for years.
How IBD differs from IBS
IBS and IBD share surface symptoms, which is why patients are often misdiagnosed for years. IBS does not cause inflammation, ulcers, or tissue damage. IBD does. If you have blood in your stool, persistent diarrhoea, or unexplained weight loss, please see your GP.
The Reality of Living With IBD
Around 10 million people worldwide live with IBD, with prevalence rising steadily across both Western and newly industrialised countries.
Crohn's & Colitis UK estimates that roughly one in 123 people in the UK now lives with one of these conditions.
IBD is often called an invisible illness because most patients look completely fine from the outside, even when they are running to the bathroom 15 times a day, surviving on three hours of sleep, or quietly crying in a work toilet at 11am.
The fatigue alone can be disabling, and the social isolation, cancelled plans, and hidden shame do not show up on a blood test.
If someone you love has IBD, the day they "seem fine" is often the day they are working hardest to seem fine.
My Own Journey With Crohn's Disease
I was diagnosed in 2001, the year before I started high school. At the worst point I was taking 14 tablets a day, and my weight had dropped to 5 stone (33.6 kg).
On Christmas Day 2016, my bowel perforated. I was rushed in for emergency surgery and had 30 cm of diseased intestine removed. I woke up with an ileostomy bag. Two months later I was back in hospital for six weeks, fed intravenously for 12 hours a day so my body could rebuild.
When I finally got home, I made a decision. I would keep working with my medical team, and I would take ownership of my own healing alongside them. I began studying plant medicine and filled my kitchen with more than 30 different herbs.
Eight months after my ileostomy was reversed, I entered a powerlifting competition and broke two national records. Today I am medication-free and symptom-free. You can read my full journey here.
This is also why I built Cosmic Hue, the daily plant tea I wish I had during those 16 years. It is not a treatment for IBD and does not replace medical care. It is a gentle daily ritual that supports a calmer gut, alongside the rest of your routine.
How to Mark World IBD Day 2026
A few simple ways to show your support.
Wear purple on 19 May. A jumper, a ribbon, a pair of socks, anything that starts a conversation.
Share patient stories using #WorldIBDDay2026 and #IBDHasNoBorders. Your post might be the one that helps someone realise their symptoms are not normal.
If you are able, please consider supporting Crohn's & Colitis UK, a lovely charity doing great work for patients and research.
Frequently Asked Questions
What day is IBD awareness day?
World IBD Day is observed annually on 19 May. It has been recognised internationally since 2010 and is now marked in more than 50 countries across five continents.
What are the five types of colitis?
The five most commonly referenced types are ulcerative colitis, Crohn's colitis, microscopic colitis, ischaemic colitis, and infectious colitis. Only the first two fall under the umbrella of IBD.
Is IBD the same as IBS?
No. IBD involves chronic inflammation and tissue damage in the gut. IBS is a functional condition that affects how the bowel works without causing inflammation or visible damage. Symptoms can overlap, which is why proper testing matters.
What treatments are available for IBD in the UK?
NHS treatment typically involves anti-inflammatory medications, immunosuppressants, biologics such as infliximab and adalimumab, and in some cases surgery. Treatment plans depend on disease type, severity, and location, and should be guided by a gastroenterology specialist.
Conclusion
World IBD Day is a chance for the rest of the world to learn a little about what people with Crohn's or colitis carry day to day.
If that's you, you're not on your own, and your story is worth sharing.
Wear purple on 19 May, pass this along to someone who might find it useful, and be kind to anyone in your life managing something you can't see.
