Inflammatory Bowel Disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract, primarily affecting the colon and small intestine. This is triggered by body’s immune system attacking, and destroying healthy cells in the digestive tract. The two main types of IBD are Crohn’s disease and ulcerative colitis. Both cause inflammation in different parts of the digestive system. This inflammation damages the lining of the gut, leading to symptoms like abdominal pain, cramps, diarrhea, and weight loss, and can be extremely uncomfortable, severely affecting the quality of life. Though common in adults over 30, it can start at any age. However, do you know why IBD occurs? And no, it is just not about alcohol consumption. Let’s take a look…
Genetics
Family history plays a huge role in IBD. Around 20% of people with IBD have a close relative, such as a parent or sibling, who has the same disease. Scientists have identified more than 200 genetic mutations linked to IBD risk. These genes may affect how the immune system responds to bacteria in the gut, or how well the gut lining protects itself from damage. However, even though your chances of getting IBD is higher if it runs in the family, other factors too play a role, and not everyone will inherit IBD.
Antibiotics
Antibiotics too, can increase the risk of IBD. While antibiotics kill bacteria that make you sick, they also affect the gut’s protective mucus layer, since the medicine can’t differentiate between the two. This mucus acts as a barrier between the immune system, and the trillions of bacteria living in the intestines. According to doctors, antibiotics damage the cells that produce this mucus, making it easier for bacteria to penetrate the gut lining and trigger inflammation.
Urban Living
City life too, is a factor that contributes to IBD. A study from Spain found that people living in cities were more likely to develop IBD compared to those in rural areas. Urban lifestyles are often quite “sterile” as opposed to the countryside, making kids less exposed to germs that help in building immunity. In addition to urban living, lifestyle habits such as smoking, diet, and stress play a role. Smoking is known to double the risk of Crohn’s disease, although it may have a different effect on ulcerative colitis. Stress is also linked to worsening symptoms, possibly due to the gut-brain connection that influences digestive health.DietDiet is another important environmental factor in IBD. Studies show that excessive consumption of proteins, carbohydrates, and fats—common in Western diets—can increase the risk of IBD. On the other hand, eating fiber-rich foods seems to protect against the disease.Processed and junk food, that includes burgers, pastas, deep fried food, and all desserts ( high in sugar and unhealthy fats), can contribute towards gut inflammation. While food itself does not cause IBD, certain foods like alcohol, caffeine, and greasy or high-fiber foods can worsen symptoms in some people. A poor diet can disrupt the balance of gut bacteria, leading to a condition called dysbiosis, which is linked to IBD development.
MedicationsBesides antibiotics, other medications can increase IBD risk or trigger flare-ups. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen may worsen gut inflammation. Immunosuppressive drugs, used after organ transplants or to treat other diseases, can sometimes cause a form of IBD called secondary IBD.
