Diagnosis of SIBR. MCSC patient history


Patient A. applied to the MCSC named after A.S. Loginov DZM with complaints about:

  • bloating after eating;
  • aching pains in the navel area.

Earlier, he came to the clinic with the same symptoms. The therapist prescribed ultrasound of the abdominal organs, gastroscopy and a number of tests. But the conducted studies did not reveal any deviations.

Increased gas formation may be a symptom of bacterial overgrowth syndrome (SIBR). This is a condition in which bacteria multiply excessively in the small intestine. It occurs with unpleasant symptoms – bloating, flatulence, abdominal pain and stool disorders (diarrhea / constipation). 

The therapist sent the man for further examination – a hydrogen breath test with lactulose. This is an analysis of the gases in the exhaled air. However, the test results were negative. Then the doctor prescribed painkillers and drugs to reduce acidity in the stomach, but the therapy was ineffective.

At the MCSC laboratory of functional diagnostics of intestinal diseases, a gastroenterologist conducted a hydrogen-methane breath test for the patient. This method is used to diagnose disorders of the microflora of the small and large intestine, intolerance to carbohydrates (lactose, sucrose, fructose).

The man was diagnosed with excessive growth of bacteria of the small intestine, an increase in the level of methane in the exhaled air was detected. He was prescribed a comprehensive course of treatment, thanks to which the symptoms decreased after a week. And by the end of the second week they were completely hit.

The patient's history demonstrates that the absence of an increase in hydrogen during a breath test does not exclude the possibility of the presence of bacterial overgrowth syndrome. Depending on the type of overgrown bacteria, they can emit different gases – methane, hydrogen, ammonia, carbon dioxide.

Due to the use of a highly sensitive hydrogen-methane breath test, the patient was diagnosed with a predominance of methane-producing flora, which made it possible to carry out timely treatment, alleviate the patient's condition and improve the quality of life. 

The laboratory of functional diagnostics of intestinal diseases named after A.S. Loginov MCSC has all the conditions for the diagnosis of SIBR. You can do this research on high-precision equipment.
