A recent editorial in Lancet Gastroenterology and Hepatology described South Asia, including India, as a new frontier of Inflammatory Bowel Disease (IBD). Some studies have shown that IBD is as common in north India as it is in the West.
Dr Vishal Sharma, Associate Professor, Department of Gastroenterology, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, who works on TB in the abdomen and IBD, says that genetics, immune response and changes in the dietary pattern are triggers for this disease. IBD, he adds, can affect any age or gender and usually, these patients have abdominal pain, diarrhoea and bleeding in stools.
The diagnosis is often delayed because of a lack of awareness about the disease in the community, lack of access to colonoscopy and confusion about other diseases like haemorrhoids, abdominal tuberculosis, and cancer. Here Dr Sharma explains IBD’s occurrence, its impact on overall health, diagnostic challenges and treatment options.
These may include abdominal pain, diarrhoea, rectal bleeding and sometimes intestinal obstruction. These individuals may be malnourished and have weight loss and are at an increased risk of acquiring infections. The symptoms can be intermittent and may flare up at times. Any persistent change in bowel habits should also prompt a consultation with a healthcare professional.
I agree that there can be diagnostic delays due to a lack of awareness, limited access to diagnostic tools, and confusion with other diseases. Increased awareness, accessibility to healthcare facilities and a high index of suspicion amongst physicians can help in the early detection and management of IBD. While as of now, there is no known permanent cure for IBD, the symptoms can often be managed effectively through therapies. We have often noticed that rectal bleeding is ignored and believed to be due to piles while the diagnosis of diseases like colon cancer and IBD gets delayed.
IBD, including conditions like Crohn’s disease and ulcerative colitis, can have a significant impact on overall health, affecting physical well-being, quality of life and even mental health. The burden of healthcare and therapy costs is well recognised in chronic diseases including IBD. The diagnostic challenge lies in its overlapping symptoms with other GI diseases, thus requiring a comprehensive evaluation. In India, differentiating from infectious mimics, especially gastrointestinal tuberculosis, is a significant challenge.
A sedentary lifestyle, high-sugar and high-fat diet are considered potential risk factors for IBD. There isn’t a specific age group that’s more affected, but it’s often first noticed in young adulthood. Moreover, these may not be operative for each patient individually. The cause is multifactorial with an interplay of genetic and environmental factors.
Management of IBD is usually multifaceted. Drug therapies are helpful in controlling symptoms, helping avoid surgery and reducing the risk of cancers associated with IBD. Aggressive disease may need aggressive therapy which could modify the natural course of the disease. One hopes that the recent advances in the understanding of the disease would help provide cheaper and more effective therapeutic options.
It’s crucial to have an open communication with your healthcare provider about your symptoms and concerns. The management plan should be personalised, depending on the severity of symptoms, triggering factors and individual preferences. The management is multifaceted and includes aspects of preventive care (vaccinations, bone and mental health assessment), drug therapy (which is cost-effective and controls the disease effectively), prevention and screening for complications like colon cancer. Certain complications may require surgical intervention. Everyone with IBD is unique, and what works for one person may not work for another. Therefore, it’s important to approach treatment and management on a personalised basis, with patience and perseverance. Most patients would be on some form of treatment lifelong which helps them lead an almost normal life.
Irritable Bowel Syndrome (IBS) is different from IBD. However, like IBD, the etiology of IBS remains elusive, but it indeed appears to be a multifactorial disorder. Factors such as altered gut-brain communication, changes in the gut microbiota, prior GI infections, stress and dysmotility are thought to contribute to its development. A personalised approach, considering these factors, is usually adopted for its management.
