The tendency to such a reaction is genetically inherited and can be triggered by various environmental influences.\r\n\r\nNon-immunological intolerances (especially of food) are called intolerances. This occurs, among other things, when the body lacks a certain enzyme to break down a food or to transport it through the intestinal wall. Symptoms similar to those of intolerances can also occur if the small intestine is colonized with colon bacteria (DDFB, SIBO).\r\n\r\nTo find out whether you have an allergy, intolerance or

The symptoms are often abdominal pain, a feeling of fullness and diarrhea. The diagnosis is made using an H2 breath test.<\/h3>\n<p>In contrast to milk allergy, lactose intolerance is caused by the lack of a special enzyme (lactase). Lactose itself is not absorbed and then reaches the large intestine, where local bacteria break down the lactose. This creates intestinal gases and acids, which can lead to significant discomfort with abdominal pain, sometimes colic-like pain, flatulence and watery diarrhea.<\/p>\n<p>A detailed medical history is crucial for the diagnosis. A food diary can be very helpful here. The diagnosis can be confirmed using the lactose tolerance test or the <a href=\"https:\/\/allergiezentrum.at\/en\/allergy-tests\/\" target=\"_blank\" rel=\"noopener\">H2 breath test<\/a>.<\/p>\n<p>To find out whether you have an allergy or intolerance to certain substances, ask your doctor to refer you to a consultation at the allergy center.

Consuming foods containing fructose can then lead to abdominal cramps, bloating and diarrhea.<\/h3>\n<p>The cause of fructose malabsorption lies in a disruption of the GLUT-5 transport system, which in healthy people ensures the absorption of fructose from the small intestine. If absorption is disrupted, the fructose ingested with food reaches deeper parts of the intestine, where it is broken down by bacteria. This produces large amounts of hydrogen, carbon dioxide and short-chain fatty acids, which can lead to abdominal pain, flatulence and diarrhea.<\/p>\n<p>Keeping a food diary followed by dietary advice can be a game-changer.

As a result, food components are broken down prematurely by these bacteria and gases are produced. The typical symptoms are flatulence, diarrhea and weight loss.<\/h3>\n<p>Bacteria are also normally present in certain parts of the intestine. They perform an important role in digestion and immune defense. However, if the wrong intestinal bacteria are present in too large numbers in the wrong place in the intestine, symptoms can arise (bacterial overgrowth, SIBO = small intestinal bacterial overgrowth). Sugar (glucose) in particular is then broken down early by these bacteria and intestinal gases (e.g. hydrogen, H2) are produced. This can then lead to various symptoms, such as bloating, a feeling of fullness or diarrhea.<\/p>\n<p>The medical history is often very unspecific. A specific food cannot always be identified. Therefore, diagnosis using an <a href=\"https:\/\/allergiezentrum.at\/en\/allergy-tests\/\" target=\"_blank\" rel=\"noopener\">H2 breath test<\/a> is important. If the test is positive, intestinal cleansing (usually antibiotics) can be carried out after consultation with a gastroenterologist.<\/p>\n<p>It can often be important to rule out lactose intolerance or fructose malabsorption before glucose testing, which can also be a cause of bacterial overgrowth in the small intestine.<\/p>\n<p>To find out whether you have an allergy or intolerance to certain substances, ask your doctor to refer you to a consultation at the allergy center.
