Diagnosis of lactose intolerance

Hydrogen Respiratory Test

It is the main diagnostic method. This test detects the amount of hydrogen in the breath after consuming a dose of lactose based on age and weight. A fasting period of 6-12 hours is necessary depending on age. Hydrogen samples are taken by blowing in a closed container. A solution of about 25 g of lactose in water is administered and must be consumed in a certain time. Next, new respiratory samples are taken every 15-20 minutes to analyze the levels of hydrogen, since people with lactose intolerance produce more hydrogen in their breathing due to malabsorption of lactose.

Depending on the amount of hydrogen produced by the organism, a more or less severe intolerance will be determined. The test lasts 3-4 hours.

Diet For Allergy Or Intolerance To Cow's MilkLactose tolerance test in blood

It consists of various blood extractions that check blood glucose levels. And why glucose? Well, because when we consume products with lactose, the lactase enzyme breaks down lactose into two smaller molecules: glucose and galactose. So, after consuming lactose, glucose levels in our body are increased, and if not, there is a deficit of lactase and consequently, intolerance to lactose.

This test is very similar to the previous one, but instead of extracting respiratory samples, the samples are blood. The test requires an 8-hour fast. Then you should take a dose of lactose mixed with water. After 30 minutes a first blood sample will be taken, which will be repeated after 1 and 2 hours afterwards. If your body has less than 20 mg of glucose per deciliter of blood, there is intolerance to lactose.

Other tests of Intolerance to cow’s milk

In the intestinal biopsy a sample of intestinal mucosa is extracted to analyze lactase levels. The test is done through an endoscopy, but it is not the most reliable, since lactase activity levels may vary depending on the area of ​​the intestine.

There is also a genetic test to detect genetic variations in the DNA that would indicate intolerance to lactose. In the case of babies, whose diet is practically based on milk, the pH analysis in the feces can be used  to diagnose lactose intolerance.

Diet For Allergy Or Intolerance To Cow's MilkLactose-free diet

After suspicion of intolerance to cow’s milk (lactose), you must follow a strict diet without lactose, at least 10 days and if symptoms improve, try to reintroduce these foods, as we may be facing a temporary lactose intolerance, frequent after gastroenteritis or antibiotic treatment.

If you worsen with the reintroduction of dairy products, you probably have an intolerance to cow milk (lactose) more severe and that requires a lactose-free diet for months or even for life.

  • whole milk, semi-skimmed, skimmed (cow, goat, sheep, maternal)
  • milk powder
  • milk shakes
  • juices with milk
  • fresh cheese, semi-cured, spreadable (cured cheese is better tolerated)
  • yogurt (contains less lactose than milk but is added in the manufacturing process)
  • dairy desserts
  • sauces with milk (bechamel, mayonnaise)
  • ice creams
  • pastries
  • Sausages
  • Butter
  • Candies
  • Medicines
  • Bread

Nutritional deficits in a dairy-free diet

To compensate for a lower intake of calcium, the consumption of sardines (whole), green leafy vegetables (chard, spinach, cabbage), legumes (beans, chickpeas, lentils), nuts (peanuts, pistachio, walnuts), olives increases. Strawberries, etc.

As lactose favors the assimilation of calcium, in some cases a vitamin D supplement may be necessary, especially if you are a woman, you are in menopause or you have been diagnosed with osteoporosis. Ask your doctor or pharmacist, with a simple blood test you can detect vitamin D.
