Fructose intolerance is a medical condition characterized by the inability of the body to properly absorb and process fructose, a type of sugar found in many foods and beverages. Some other synonyms for fructose intolerance include fructose malabsorption, dietary fructose intolerance, and hereditary fructose intolerance. In some cases, fructose intolerance may be referred to as fructose sensitivity or fructose allergy, although these terms are not entirely accurate as they do not signify a true allergic reaction. Individuals with fructose intolerance may experience a range of symptoms such as bloating, abdominal pain, diarrhea, and nausea after consuming foods containing fructose. Treatment options may include dietary changes and the avoidance of foods high in fructose.
