Link between the malabsorption of fructose (intolerance) and the IBS


Fructose is a type of sugar found in fruits, vegetables and honey.Fructose is also found in the brain syrup with a high fructose content, which is an artificial sweetener used in canned fruits of sodis and packaged desserts.In some people, the swallowing of products that contain this type of sugar causes unpleasant digestive symptoms, such as swelling, abdominal discomfort and diarrhea.


The study shows that this is a state called intolerance A fructose sequences or even cause the symptoms of a bowel disaster in some patients whoThey use an irritable intestinal syndrome (SII). DEFECT, the identification of fructose intolerance is the key component of the theory, using the diet low-Fodmap for IBS .

Review of fructose intolerance

Intolerance to fructose is produced as a result of fructose sugar, it is not completely absorbed into the small intestine. As a result, as a result, the undeclared fructose enters a large intestine, where it is installed and fermented in an intestinal bacteria . This metabolism of fructose causes undesirable gases, swelling, diarrhea and abdominal pain.

Fructose intolerance is noticeably different from the state different from hereditary fructose intolerance, genetic disorder, Generally diagnosed in childhood.

Investigate with IBS

Identification of the backup of the investigation of intolerance to fructose as the reason for intestinal intestinal,As well as its possible reference to the rejection of IBS

one of the small studies was a comparison of healthy people and people who were identified depending on fructose intolerance according to the fact that they experienced the swelling of the abdomen andMeteorism after using certain fruits. Patients with self-esteem were higher levels of hydrogen breathing and received more inflated experience and meteorism as a result of the use of fructose solutions than healthy people. .Intolerance to fructose.

Interestingly, of these 80 patients, 26 participated in the subsequent evaluation in one year.When it is observed, 14 of these patients reported that they were able to observe the limited diet of fructose, and these participants experienced a significant improvement in the symptoms of pain, splashing, painting and blowing diarrhea.Patients who have not respected did not adjust to the fructose diet, continued to have symptoms.

Diagnosis of fructose intolerance

Intolerance to fructose, as a general rule, is diagnosed with a diagnosed breathing test breathing ,What measures the amount of hydrogen in breathing after swallowing the fructose solution.

of notes, the fructose intolerance test is similar to the lactose intolerance test,Except that your breathing is analyzed for hydrogen gas after the consumption of fructose is dissolved in water (and not lactose containing a drink).

With a mass in antoterance to fructose, a high level of hydrogen at your breath indicates that fructose in the solution is fermented by bacteria in the colon. This says that his little intestine is experiencing difficulties that absorb fructose. / P>

Unfortunately, the hydrogen respiration test is not entirely reliable. It can show a positive result, even if it does not have malabsorption. Although some say that the test is still valuable, others indicate their lack of reliability.

Differential diagnosis

ALSO, small small intestal (SIBO) Possible diagnosis when The hydrogen breathing test is positive.Your health care provider must determine whether the possibility of intolerance to Sibo or Frucosta has a correct diagnosis to describe its condition. SIBO Diagnostics can be confirmed by a hydrogen respiration test analyzed after the use of sugar containing glucose or lactulose (non-fructose).

Word to obtain information about obtaining medications

idea that fructose intolerance can take to the fact That some people still make fun of.However, did he have a diagnosis of IBS if he experiences the symptoms of the gastrointestinal tract after eating rich in fructo grocery products,Take into account the intolerance to fructose as a possible explanation?
