Lactose intolerance panel 57 €

  • Is the uncomfortable feeling after consuming dairy products, excessive gas and bloating, diarrhoea or abdominal pain caused by lactose intolerance?
  • Do I have lactose intolerance due to genetic predisposition or is it a symptom of a bowel disease (celiac disease, irritable bowel syndrome, Crohn’s disease, inflammatory bowel disease)?
WHAT DOES THE PANEL CONTAIN?
  • 2 blood tests – the results help to find answers to the above questions.
  • Written explanations of the results – the results come with explanatory comments.
  • Lab doctor’s telephone consultation – a lab doctor will contact you to explain your personal results and give advice regarding future steps, if necessary.
HOW TO PREPARE FOR GIVING THE SAMPLE?
  • Refrain from eating and drinking 12 hours before giving the sample.
  • Reserve at least 1 hour for giving the sample. During the procedure, you will be taken three venous blood samples in short intervals.
  • To take the lactose intolerance test, you are asked to drink a lactose solution. When people with lactose intolerance drink the solution, they may develop abdominal discomfort already when taking the test or during the day of testing, including excessive gas and bloating, diarrhoea, etc.
HOW CAN I SEE MY RESULTS?

The panel results will be displayed in this portal (under “Results”) along with written comments and the lab doctor’s telephone consultation within 5 working days.

WHAT IS LACTOSE INTOLERANCE?

Lactose intolerance (also milk sugar intolerance, hypolactasia) is caused by lactose (also known as milk sugar) malabsorption due to reduced activity or the enzyme lactase. Due to this, a smaller or larger portion of lactose remains unprocessed and unabsorbed in the small intestines. As a result, the microbes in the large intestine cause gas and acids, which may give rise to abdominal discomfort: excessive flatulence and bloating, stomach growling, stomach pain and diarrhoea.

In most people, the body produces lactase throughout their life, but the activity of its production is the highest among infants and toddlers, as in this phase milk is the primary food that the body needs. When other foods are introduced in the menu, the need for a large amount of lactase disappears and its activity is gradually reduced in time. This is why older people may be less tolerant to dairy products than children and teens. Some lactase activity (usually 50–70%) is preserved.

CAUSES OF LACTOSE INTOLERANCE

Primary lactose intolerance or primary hypolactasia is caused by a genetic predisposition and usually manifests between the ages of 5 and 20. In such people, the gene regulating lactase production is “switched on” only during the first years of life, after which the lactase activity slows significantly and the person’s ability to digest milk sugar also decreases accordingly. In Estonia, approximately 20–30% of the population have primary lactose intolerance. This condition is incurable; the symptoms vary in severity and can be prevented with proper nutrition.

Secondary lactose intolerance is caused by small intestine damages co-occurring with digestive tract diseases, such as celiac disease, Crohn’s disease, irritable bowel syndrome, etc. Secondary lactose intolerance can also occur in infants and toddlers after bowel diseases. The symptoms usually disappear within 2–4 weeks after the primary disease has subsided.

WHEN TO SUSPECT LACTOSE INTOLERANCE?

Possible symptoms indicating lactose intolerance include abdominal pain, abdominal cramps, excessive gas and bloating, diarrhoea, occasionally also vomiting directly or a few hours after consuming lactose-containing products. The severity of the symptoms depends on the amount of dairy products consumed and the remaining activity level of the enzyme lactase.

Lactose intolerance symptoms and their severity levels vary and can overlap with symptoms of other conditions, including the irritable bowel syndrome and celiac disease.

WHAT ARE THE CONSEQUENCES OF LACTOSE INTOLERANCE?

Consumption of lactose-containing products despite lactose intolerance causes post-meal indigestion, which may result in impaired absorption of various nutrients.

Lactose intolerance does not always mean full intolerance – in many cases a person can eat products with a low lactose content.

Since dairy products contain calcium which the body needs, then in case of a lactose intolerance diagnosis it is important to conduct a thorough nutritional review to ensure that the body receives the most important nutrients with food.
