Fructose intolerance, also called hereditary fructose intolerance (HFI), is a rare genetic disorder that affects the way the body processes fructose, a type of sugar found in many foods and beverages. In this disorder, the body is unable to properly break down fructose, which can lead to a range of symptoms and health complications.
In this blog post, we'll go over the causes, symptoms, diagnosis, and treatment options for fructose intolerance.
Causes
Fructose intolerance is caused by a deficiency of the enzyme aldolase B, which is required for the breakdown of fructose in the liver. This enzyme deficiency is inherited in an autosomal recessive manner, which means that a person must inherit two copies of the defective gene, one from each parent, to develop the disease.
Symptoms
Symptoms of fructose intolerance usually occur shortly after consuming foods or beverages that contain fructose, sucrose, or sorbitol. The most common symptoms of fructose intolerance include:
- Abdominal pain
- Flatulence
- Diarrhea
- Nausea and vomiting
- Fatigue
- Headache
- Weight loss
- Jaundice (yellowing of the skin and eyes)
- Hypoglycemia (low blood sugar)
- Elevated liver enzymes
In severe cases, fructose intolerance can lead to liver and kidney damage and other serious health complications.
Diagnosis
Fructose intolerance can be diagnosed by a number of tests, including a fructose tolerance test. In a fructose tolerance test, the patient is given a drink containing fructose. The patient blows into a test tube at regular intervals and their symptoms are monitored over a period of time. After about two hours, the hydrogen content in the breath can be used to assess whether he is suffering from fructose intolerance.
Treatment
The main treatment for fructose intolerance is a strict, low-fructose diet that avoids foods and beverages that contain fructose, sucrose, and sorbitol. It can be difficult to follow this diet because fructose is found in many common foods and beverages, including fruit, honey, and many processed foods.
Some examples of foods that should be avoided by people with fructose intolerance are:
- Apples, pears and other fruits with high fructose content
- Honey, maple syrup and other high fructose sweeteners
- Soda, fruit juices and other sugary drinks
- Processed foods containing high fructose corn syrup
In addition to a low-fructose diet, people with fructose intolerance may need to take vitamin and mineral supplements to ensure they get all the nutrients they need. In some cases, medications may be prescribed to treat symptoms such as abdominal pain and diarrhea.
Summary
Fructose intolerance is a rare genetic disorder that affects the way the body processes fructose, a type of sugar found in many foods and beverages. The condition is caused by a deficiency in the enzyme aldolase B, which is needed to break down fructose in the liver. Symptoms of fructose intolerance include abdominal pain, bloating, diarrhea and nausea. Treatment for fructose intolerance includes a strict low-fructose diet and, in some cases, vitamin and mineral supplements and medications. If you suspect you have fructose intolerance, be sure to seek medical advice for an accurate diagnosis and appropriate treatment.

Painkillers for histamine intolerance
Many people with histamine intolerance are initially unaware that many painkillers are also unsuitable. This is because most painkillers contain so-called histamine liberators. These are substances that release the body's own histamine in mast cells. DAO blockers can also be a problem. DAO is the main degradation pathway in the intestine. Certain substances can inhibit DAO enzyme activity by their presence in the body. As you can see, the question "Which painkillers for histamine intolerance?" is not so easy to answer. On the one hand, it is necessary to check whether the active ingredient is tolerated. On the other hand, it is also necessary to check which excipients are contained in the medication.
