Dysbiosis is a term used to describe an imbalance in the microbial community within the gut. This imbalance can occur due to various factors such as diet, antibiotics, stress, or illness, and can lead to a variety of health problems. Dysbiosis is believed to play a role in a range of conditions including irritable bowel syndrome, inflammatory bowel disease, obesity, and autoimmune diseases. Researchers are studying ways to restore a healthy balance of gut bacteria in order to improve overall health and well-being.
