About Fructose Intolerance
Fructose, found in common granulated sugar (sucrose), can cause intestinal and stomach issues when not properly broken down or absorbed. Fructose intolerance, also known as fructosemia, occurs when the body struggles to break down fructose in the blood due to an enzyme deficiency. Often hereditary, this condition's severity varies, with some experiencing no symptoms and others severe discomfort.
Understanding the GetTested Fructose Intolerance Test
GetTested's fructose intolerance test evaluates your ability to metabolize fructose, identifying potential malabsorption issues. It offers a comprehensive assessment, distinguishing itself from other tests that focus solely on genetic factors.
Symptoms of Fructose Intolerance
Symptoms can include gas, cramps, stomach pain, and diarrhea. Severe cases, particularly in children, might lead to acute illness, breath shortness, and altered blood pH levels. Fructose overload over time can damage the liver and kidneys. Additional symptoms to monitor include tremors, seizures, and abnormal sweating. Often, symptoms first appear following infections or antibiotic treatments, although reduced fructose absorption likely existed since childhood. Testing for lactose intolerance is also advisable, as it often coexists with fructose intolerance.
Causes of Fructose Intolerance
Fructose is a monosaccharide that, combined with glucose, forms sucrose. Its absorption requires the fructose-1,6-bisphosphate aldolase enzyme. A deficiency in this enzyme causes fructose to accumulate, potentially impacting the liver, kidneys, and intestines. Classified into two types, fructose intolerance can be:
- Essential Fructosuria: A mild form, managed by moderating dietary fructose.
- Congenital Fructose Intolerance: A severe, congenital enzyme deficiency, which can be life-threatening if untreated.
How the GetTested Fructose Intolerance Test Works
The test is a breath analysis conducted over three hours, with samples collected at five intervals. To ensure accurate results, avoid consuming fructose before and during the test. A minimum 8-hour fast is recommended prior to testing. Samples are analyzed at the GetTested lab, with digital results provided upon completion.
Treating Fructose Intolerance
Due to the high fructose content in the Western diet, fructose intolerance prevalence may be increasing. It affects both individuals with and without IBS (Irritable Bowel Syndrome). For those with this intolerance, managing the condition through early dietary adjustment is crucial to prevent serious complications involving the liver and kidneys.
