During this time, your doctor will collect your hydrogen measurements and monitor your symptoms.Īnother way to diagnose lactose intolerance is the milk tolerance test. After drinking it, you will be asked to breathe into a special container every 30 minutes over a period of a few hours.

A medical professional will provide you with a dose of liquid drink containing a small amount of lactose. When lactose is not being absorbed, it can lead to abnormally high levels of hydrogen in your breath. The most common test used to diagnose lactose intolerance is the hydrogen breath test. If they persist despite changing your diet, certain additional tests may be needed to obtain a diagnosis. They may also ask you to stop eating and drinking dairy products for a period of time to see if your symptoms go away. Afterwards, your doctor will usually conduct some tests to check for lactose malabsorption and to exclude other chronic conditions which may present similar symptoms (such irritable bowel syndrome, celiac disease, or small bowel bacterial overgrowth). They may also perform a physical examination. They will enquire about your symptoms, family history, eating habits and the kind of medications you take regularly. First, your doctor will ask you many questions to get a good understanding of your personal and medical history. Lactose intolerance: Diagnosis and testingĭiagnosing a lactose intolerance involves several steps. Infections and certain diseases, such as Crohn’s disease and celiac disease, can affect the body’s ability to digest lactose. Lactose intolerance can also be triggered by an injury to the small intestine and this condition is often referred to as secondary lactose intolerance. Whereas congenital lactase deficiency, a condition in which people start experiencing the symptoms from birth, is less common. This is why many lactose intolerance tends to be diagnosed later in life. These faulty genes can lead to lactase non-persistence (also referred to as primary lactase deficiency), a condition where lactase levels start dropping after infancy. In some people, genes responsible for the production of lactase do not work properly. According to a review published in the Nutrients journal, the most common cause is rooted in genetics. There are a few reasons why people develop lactose malabsorption. This process increases the amount of fluid and gas in your gastrointestinal system. When undigested, or partially digested, lactose passes into your colon, where it’s broken down by gut bacteria. Lactose intolerance is usually the result of your body not producing enough lactase – a digestive enzyme that breaks down lactose molecules to glucose and galactose. The severity of these symptoms changes, depending on the amount of lactose ingested and the state of one’s health. Lactose intolerance: Symptoms and causesĪccording to the National Institute of Diabetes and Digestive and Kidney Diseases, common symptoms of lactose intolerance include bloating, diarrhea, excessive gas, nausea, pain in the abdomen, and vomiting.
In the United States, African Americans, American Indians, Asian Americans and Hispanics tend to have higher rates of lactose malabsorption. Certain ethnic and racial groups are more likely to be at risk too. Some individuals can tolerate much higher amounts of dairy sugar before having any symptoms. Lactose intolerance affects people differently. A milk allergy can cause a life-threatening allergic reaction to the proteins found in dairy milk and often appears in infancy, whereas lactose intolerance typically appears later in life and doesn’t pose a risk to life.
Lactose intolerance is also different to a milk allergy, which is an immune system disorder.
