Hereditary Fructose Intolerance

Summarized by Plex Health
Last Updated: 02 May 2022

Hereditary fructose intolerance is a condition that influences a person's ability to absorb the sugar fructose. Fructose is a straightforward sugar found mainly in fruits. After ingesting fructose, individuals with hereditary fructose intolerance may experience nausea or vomiting, bloating, abdominal pain, looseness of the bowels, vomiting, and low blood sugar. Affected babies may fail to gain and grow weight at the expected rate. The liver damage can cause a yellowing of the skin and whites of the eyes, an enlarged liver, and persistent liver disease. Due to the severity of symptoms experienced when fructose is ingested, many people with hereditary fructose intolerance develop a disapproval for fruits, juices, and other foods containing fructose. Hereditary fructose intolerance should not be confused with a problem called fructose malabsorption. In people with fructose malabsorption, the cells of the intestinal tract can not soak up fructose normally, leading to bloating, diarrhea or bowel irregularity, stomach, and unwanted gas pain.
