Hereditary Fructose Intolerance and
A Fructose Free Diet

Hereditary fructose intolerance is a disorder that you are born with and may strike more people of European descent or Caucasian people

This disorder can strike about 1 in 20,000 people which makes it a somewhat common health problem.  This will lead to fructose metabolism problems which can create unpleasant as well as very serious health issues. 

And the only way to deal with a serious fructose metabolism problem created by hereditary fructose intolerance may be to adopt a fructose free diet.

Tests Used to Diagnose
Hereditary Fructose Intolerance

  • Enzyme Tests
  • Urine Tests
  • Blood Tests
  • Fructose Tolerance Test
  • Liver Biopsy

It's a Genetic Disorder

This is a genetic disorder that you were born with and it can be inherited from someone in your family - like your parents.

The people that have hereditary fructose intolerance will not be able to properly metabolize fructose.  This is due to a deficiency of a particular liver enzyme which converts fructose into glucose.  Which will end up being a big problem for people with this genetic disorder these days.

Fructose Metabolism Problems

Normally, fructose is absorbed through your small intestine and is then sent to your liver to be converted into glucose. However, when your liver is missing "the" particular "enzyme", fructose can no longer be converted and you will experience fructose metabolism problems.

This will put a huge strain on your body, especially your liver and kidneys!

When fructose can't be converted, it will then start to accumulate in your body and this may result in Acidosis.  Attempts to deal with this unusable sugar create toxic substances such as uric acid and severe abdominal pain.  Vomiting may soon follow the ingestion of fructose.

Symptoms of Hereditary Fructose Intolerance or (HFI)

  • Abdominal Pain
  • Bloating
  • Flatulence
  • Vomiting
  • Diarrhea
  • Extreme Thirst
  • Excessive Sweating
  • Hypoglycemia
  • Convulsions
  • Acidosis
  • Excessive Urination
  • Fatigue
  • Fever
  • Depression
  • Excessive Sleepiness
  • Irritability
  • Failure to Grow
  • Weight Loss
  • Jaundice
  • Enlarged Liver
  • Kidney Problems

If you think that you suffer from a fructose metabolism problem like HFI, pay attention to what happens after eating fruit or other foods that contain an ample amount of fructose. And if you suspect that you can't digest fructose - have it checked out by someone licensed to do this type of testing.
