Small Intestinal Bacterial Overgrowth (SIBO) Diagnostics Market Drivers and Opportunities
Increasing Prevalence of Irritable Bowel Syndrome (IBS) to Favor Market
Irritable bowel syndrome (IBS) is the commonly diagnosed gastrointestinal disorder with abdominal pain and altered bowel habits resulting with associated symptoms such as bloating, malabsorption, and systemic symptoms. Crohn's disease and ulcerative colitis are types of IBS. It causes swelling in the digestive tract, which can cause abdominal pain, diarrhea, fatigue, weight loss, and malnutrition. According to MedlinePlus, Crohn's disease is most prevalent in Western Europe and North America, with a prevalence rate of 100 to 300 per 100,000 people. According to the Medscape data, the incidence of ulcerative colitis in the US is 10.4–12 cases per 100,000 people, and the prevalence rate is 35–100 cases per 100,000 people. As compared to Crohn disease, ulcerative colitis is three times more common. IBD is thought to be a result of a multitude of environmental and bacterial interactions with immune-mediated factors in a genetically susceptible host. The increasing prevalence of IBS across the world is due to the changing lifestyle and dietary habits. Small intestinal bacterial overgrowth (SIBO) is widely associated with the IBS. Thus increasing prevalence of IBS fuelis the growth of the SIBO diagnostics market as it increases the prevalence of SIBO.
Development of Capsule Technology act as an Opportunity for Market Growth
The growing technological developments in the field of medical devices have offered various innovative products to diagnose several complex human health conditions. Thus, to diagnose SIBO, an innovative orally ingested capsule technology is in the developmental process. It is designed in a way to measure in vivo hydrogen and carbon-di-oxide after ingestion of a carbohydrate meal and provide a technologically updated alternative to the current breath hydrogen test. It is expected that the capsule technology will help in diagnosing samples of small bowel bacteria. Thus, the introduction of capsule technology is likely to emerge in the coming future and contribute to direct and accurate evaluation of SIBO and offer vital growth opportunities for the market’s growth.
