What is Fructose Intolerance?
Dietary fructose intolerance or fructose malabsorption is a digestive disorder that occurs when the small intestines cannot absorb a normal amount of fructose in the diet. While the average person has a limit on the amount of fructose they can comfortably digest in one sitting, a patient with dietary fructose intolerance has a much lower threshold. Excess, undigested fructose can ferment, irritating the intestines, altering the balance of bacteria, and causing a variety of unpleasant symptoms.
If you have fructose intolerance, you may experience a number of symptoms within half an hour to 2 hours of consuming foods that contain fructose. Your symptoms may include bloating, diarrhea, constipation, indigestion, excess gas, abdominal pain, and nausea.
There is a breath test for fructose intolerance, called the fructose hydrogen breath test, which is performed at some laboratories. If you suspect fructose intolerance, avoiding fructose for 2 weeks and evaluatingsymptoms can sometimes strengthen the evidence for this.
Dietary changes will help you manage your symptoms. Avoiding foods that contain sweeteners with fructose is the treatment for this.
