A Low FODMAP Diet is a type of eating plan designed to help individuals manage symptoms of irritable bowel syndrome (IBS) and other functional gastrointestinal disorders. FODMAPs are short-chain carbohydrates that are poorly absorbed in the small intestine. They include fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. When consumed, these carbohydrates can lead to symptoms such as bloating, gas, diarrhea, and constipation.
