Celiac disease is an autoimmune disorder that affects the small intestine, causing an intolerance to gluten. When someone with celiac disease consumes foods containing gluten, their immune system reacts by damaging the small intestine lining, leading to nutrient malabsorption and various symptoms such as diarrhea, abdominal pain, and fatigue. Research in celiac disease focuses on understanding its causes, developing better diagnostic tools, and finding new treatment options. This includes investigating genetic factors that predispose individuals to the disease, exploring the role of the gut microbiome in celiac disease development, and developing gluten-free alternatives for patients with the condition. Additionally, researchers are also studying the impact of celiac disease on quality of life and mental health, as well as potential long-term complications such as osteoporosis and certain cancers. Overall, research in celiac disease aims to improve diagnosis, treatment, and management strategies for individuals living with this chronic condition.
