The set of microorganisms that live in the intestine constitutes the intestinal microflora, also called intestinal microbiota or intestinal flora. Our intestinal microbiota plays a very important role in nutrition and food metabolism. The intestinal microbiota is also part of the intestinal barrier that prevents the colonization or overgrowth of non-beneficial bacteria, as well as the proper functioning of the immune system. Certain situations can alter the balance of the intestinal microbiota, interfering with digestive well-being. Changes in intestinal balance caused by occasional diarrhea caused by viruses or bacteria, taking antibiotics that can affect the microorganisms that make up the intestinal microbiota, stressful situations, and travel are some of the circumstances that can cause this imbalance. In these cases, act immediately to protect your intestinal flora.
