Dysbiosis refers to an imbalance in the microbial communities living in and on the human body, particularly in the gut. This condition can occur when harmful bacteria outnumber beneficial ones, leading to various health issues. Factors contributing to dysbiosis include poor diet, stress, antibiotics, and infections. The consequences of dysbiosis can range from digestive problems, such as irritable bowel syndrome (IBS), to more serious conditions like inflammatory bowel disease (IBD) and even obesity. Restoring a healthy balance of gut bacteria often involves dietary changes, probiotics, and lifestyle adjustments to promote overall well-being.
