Ask Dr. Etingin : What is "fructose intolerance"?

   "Fructose intolerance can exist in serious or mild forms. The more serious condition is known as hereditary fructose intolerance, a rare genetic disorder. People with that condition lack an enzyme needed to break down fructose during digestion. Liver and kidney damage can result.
Typically, hereditary fructose intolerance is identified and diagnosed at a younger age.
   "The less serious form of fructose intolerance is actually known as fructose malabsorption, which means a person has trouble digesting fructose. Symptoms include bloating, abdominal cramps, gas, and diarrhea, but not kidney or liver damage.
   "Fructose is a natural sugar found in fruits, nuts and honey. It is frequently added to sodas, sports and fruit drinks, flavored waters, and corn syrup. If you suspect you are fructose intolerant, consult with a doctor. The condition can be confirmed through testing.
   "A dietitian could help you map out an eating plan to help avoid fructose if you are fructose intolerant."
