Ulcerative colitis, or ulcerative colitis, is a chronic, autoimmune disease that affects the colon and typically spreads upwards from the rectum. The disease is associated with unpleasant symptoms such as bloody, pus-filled diarrhoea, abdominal cramps and an urgent urge to defecate, which can significantly impair quality of life. Many people ask the question: can ulcerative colitis be prevented? Although the exact cause of the disease is not known and there is no single, sure-fire way to prevent it, knowing the risk factors and making certain lifestyle changes can reduce the chances of developing the disease and can have a positive impact on its course. In this article, we describe possible prevention strategies in detail.
Risk factors for Ulcerative Colitis
The first step in prevention is to understand the risk factors. Although anyone can develop ulcerative colitis, certain factors can increase the likelihood of developing it.
Genetic predisposition and familial accumulation
Research clearly shows that genetic factors play an important role in the development of inflammatory bowel diseases (IBD), including ulcerative colitis. If a close relative (parent, sibling) is affected, the risk of developing the disease is increased. This familial cumulation suggests that certain gene variants (such as HLA genes) may predispose to the disease. It is important to emphasise that genetic predisposition alone does not mean that the disease will definitely develop; other environmental and lifestyle factors are also necessary.
Environmental factors and lifestyle
The modern, western lifestyle has many elements that have been linked to an increase in the prevalence of ulcerative colitis.
- Smoking: Interestingly, smoking has the opposite effect on the two most common inflammatory bowel diseases. While it increases the risk of Crohn's disease, a „protective” effect has been observed in ulcerative colitis. Smokers are less likely to develop the disease and the course may be milder. However, after smoking cessation, the disease may flare up or even appear for the first time. However, because of the many other serious health effects of smoking, it is not recommended as a preventive or therapeutic tool.
- Appendectomy (Appendectomy): Several studies have shown that people who have had their appendix removed in childhood or adolescence are less likely to develop ulcerative colitis and, if they do, the course of the disease is usually milder. The exact reason for this is not yet clear, but it is thought to be related to the immunological role of the appendix.
- Medicines: Certain medicines, particularly non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or diclofenac, can irritate the intestinal lining and provoke flare-ups in people with pre-existing conditions. Although their role in the development of the disease is not yet fully established, it is best to avoid taking them regularly if inflammatory bowel disease is suspected.
- Psychological stress: Although stress alone does not cause ulcerative colitis, prolonged psychological stress has been shown to affect immune function and gut flora balance. This can contribute to flare-ups and aggravate symptoms.
The role of diet in prevention
Nutrition is key to maintaining a healthy gut. Although there is no specific „colitis diet” that guarantees prevention, certain dietary habits can reduce the risk of inflammatory processes.
Recommended foods and nutrients
- High fibre intake: A diet rich in plant fibre (whole grains, vegetables, fruits) promotes healthy gut function and nourishes beneficial gut bacteria. These bacteria produce short-chain fatty acids that reduce inflammation and protect the epithelial cells of the colon.
- Omega-3 fatty acids: The omega-3 fatty acids found in sea fish (salmon, mackerel, herring), flaxseed and walnuts have natural anti-inflammatory properties, so regular consumption can help reduce the risk of inflammation of the gut.
- Vitamin D: Vitamin D deficiency is common in people with inflammatory bowel disease and research shows that this vitamin plays an important role in immune regulation. Ensuring adequate levels of vitamin D (sunlight, fortified foods, supplementation if necessary) can be important for prevention.
Food to avoid
- Processed foods high in fat and sugar: The processed foods, refined carbohydrates and saturated fats that are typical of Western-style diets can promote inflammatory processes in the body and adversely affect the composition of the gut microbiome.
- High sulphur proteins: Some research suggests that eating proteins higher in sulphur found in red meat and certain dairy products can make ulcerative colitis patients worse, as gut bacteria can convert these compounds into inflammation-causing hydrogen sulphide.
The protective effect of breastfeeding
Several studies have shown that breastfeeding reduces the chance of developing inflammatory bowel diseases, including ulcerative colitis, later in life. Breast milk contains immunological components and nutrients that help the healthy development of the baby's intestinal tract and immune system.
The importance of the gut microbiome and mental health
Research in recent years has highlighted that the microorganisms living in our gut (the gut microbiome) and our mental state are closely linked to inflammatory bowel disease.
Balance of the gut flora
A healthy gut microbiota is essential for the immune system to function properly. If this balance is disrupted (dysbiosis), it can trigger inflammatory processes. We can support the health of the microbiome by following the fibre-rich, varied diet mentioned earlier, avoiding unnecessary use of antibiotics, and consuming foods rich in probiotics (e.g. yoghurt, kefir, sauerkraut). The role of certain pathogens (e.g. Mycobacterium, Listeria, E. coli) in the pathogenesis of the disease has also been suggested, which further emphasises the link between the gut flora and the immune response.
The importance of stress management
Chronic stress has a negative effect on the gut-brain axis, increases intestinal permeability and stimulates the production of pro-inflammatory substances. Stress management techniques such as yoga, meditation, breathing exercises or regular physical activity not only improve mental wellbeing but also indirectly support gut health, thereby reducing the risk of inflammatory diseases and the likelihood of flare-ups in existing conditions. Regular physical activity in itself reduces the risk of inflammatory bowel diseases.
The role of screening and early detection
Although we cannot prevent ulcerative colitis with absolute certainty, early detection is key to avoiding more serious complications.
- Warning signs: If you experience persistent diarrhoea, blood in your stools, abdominal pain or unexplained weight loss, you should definitely see a doctor. Do not ignore these symptoms, thinking they are just a simple case of indigestion.
- Fecal calprotectin test: This is a simple, non-invasive laboratory test that can detect the extent of intestinal inflammation from a stool sample. A high result raises suspicion of inflammatory bowel disease and warrants further, more detailed investigation, such as a colonoscopy.
- Colonoscopy (colonoscopy): A colonoscopy is the most accurate diagnostic procedure, allowing the doctor to examine the lining of the large bowel directly and to take a tissue sample, which is essential for confirming a diagnosis of ulcerative colitis.
One of the most serious long-term complications of ulcerative colitis is an increased risk of bowel cancer. The risk of developing cancer is approximately doubled in people with inflammatory bowel disease. It is therefore essential for diagnosed patients to undergo regular screening colonoscopies, usually starting 8 years after the first symptoms appear. The frequency of these examinations (every 1, 3 or 5 years) is determined by the extent and severity of the disease.

A guide to prevention and early detection
In summary, the key to preventing ulcerative colitis lies in a balanced, healthy lifestyle. Although we cannot influence genetic predisposition, there is much we can do to reduce the risk. Focus on a varied diet based on natural, fibre-rich foods, avoid processed foods, and ensure you get enough omega-3 fatty acids and vitamin D. Manage stress effectively, incorporate regular exercise into your daily routine, and avoid smoking.
Pay attention to your body’s signals and consult a specialist in good time if you experience persistent, suspicious digestive symptoms. Early diagnosis and appropriate treatment are essential for preventing serious complications, such as bowel cancer. Regular gastroenterological check-ups and screening tests provide peace of mind and help to maintain your long-term health. Remember, your health is in your hands, and prevention is always easier than treating an established condition.
