The lactose intolerance It becomes one of the most common intolerances, which most tends to affect a greater number of people in practically the entire world. In fact it is estimated that approximately 70% of the world population It presents in its diet some type of intolerance or problem to the lactose.
The lactose (milk sugar), it decomposes itself into two other simpler sugars (glucose and galactose), an issue that occurs thanks to the action of the enzyme lactase.
This process takes place specifically in the small intestine, an organ where it is possible for glucose to be absorbed into the bloodstream.
This means that when there is a lactase deficit the lactose passes into the large intestine without decomposing and begins to ferment, giving rise to a series of certain symptoms (such as gas, discomfort and heartburn).
Although these symptoms appear, the diagnosis can be more or less carried out, the truth is that medically always the most recommended is to perform a test to diagnose this intolerance.
Diagnosis of lactose intolerance
The most appropriate diagnosis is through tolerance test lactose , which is based on the measurement of the glycemic response to an overload of lactose , every 30 minutes until 2 hours after said intake, usually in 4 doses (spread over 0, 30, 60 and 120 minutes).
In a normal situation, in which there is no intolerance, the glycemia increases by 30 mg / dl from the baseline level of blood glucose at 2 hours. When this increase does not occur it may indicate that there is a deficiency of the enzyme lactase.
In addition to this test there are other useful medical forms for diagnosis:
- Exhaled hydrogen test
- Acidity of stools
- Genetic diagnosis
- Small bowel biopsy
