This also includes the tests you could find on the Internet, as these tests are not scientifically validated. Some research suggests that there could be a link between dairy intake and the risk of developing ovarian and prostate cancers.
A gastroenterologist will use a long, thin surgical tool called an endoscope to take a sample of the lining of your small intestine. An invasive intestinal biopsy is also available to diagnose lactose intolerance. Alternatively, your doctor may perform a type of blood test called the lactose tolerance test.
The most direct test for lactase deficiency is biopsy of the intestinal lining with measurement of lactase levels in the lining. The biopsy can be obtained by endoscopy or by special capsules that are passed through the mouth or nose and into the small intestine. The analysis of lactase levels in the biopsy requires specialized procedures that are not often available, and, as a result, lactase levels are not often measured except for research purposes. Lactose is a sugar molecule that is made up of two smaller sugars, glucose and galactose.
Or the small intestine sometimes stops making lactase after surgery to remove a part of the small intestine. In these cases, the problem can be either permanent or temporary.
- Treatment of the underlying disorder may restore lactase levels and improve symptoms.
- If your GP thinks you have lactose intolerance, they may suggest avoiding foods and drinks containing lactose for 2 weeks to see if your symptoms improve.
- In people with lactose intolerance caused by an underlying condition, treating the condition might restore the body’s ability to digest lactose, although that process can take months.
- Ice cream and milk contain the most lactose weight loss, but the high fat content in ice cream might allow you to eat it without symptoms.
- You might tolerate cultured milk products such as yogurt because the bacteria used in the culturing process naturally produce the enzyme that breaks down lactose.
- For other causes, you might avoid the discomfort of lactose intolerance by following a low-lactose diet.

In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose and galactose is called lactase, and it is located on the surface of the cells lining the small intestine. The National Institute of Diabetes and Digestive and Kidney Diseases estimates that 30 to 50 million Americans are lactose intolerant. Sometimes the small intestine stops making lactase after a short-term illness such as the stomach flu or as part of a lifelong disease such as cystic fibrosis.
If you’re lactose intolerant, getting the right amount of important vitamins and minerals can prove difficult. Most cases that develop in adults are inherited and tend to be lifelong, but cases in young children are often caused by an infection in the digestive system and may only last for a few weeks. The severity of your symptoms and when they appear depends on the amount of lactose you have consumed. This test detects lactose intolerance by looking for a rise in stool acidity or pH, caused by bacteria fermenting lactose in the colon.
According to The Telegraph, in 1993 Jane Plant developed breast cancer for the fifth time; she was told she only had months to live. Plant decided to switch to a dairy-free, Asian-style diet while she was undergoing chemotherapy. Within six weeks, the lump on her neck vanished and within a year she was in remission. Lactose intoleranceoccurs because the body is not producing enough lactase, which is the enzyme that breaks down lactose in the small intestine. They can advise you on your diet and whether you require food supplements.
