The first thing we are going to do is discover the etymological origin of the term lactose. Specifically, we can determine that it comes from Latin, more precisely from “lac, lactis” which can be translated as “milk”.

Lactose is the sugar (made up of glucose and galactose) that is present in the milk. It is a disaccharide that is found in a proportion of between 4% and 5% in the milk of female mammals.

LactoseIn the case of Humans, the correct absorption of lactose requires the presence of an enzyme called lactase (produced in the small intestine and synthesized during childhood). If the body has little or no amount of lactase, lactose cannot be assimilated correctly and various discomforts occur.

Lack of lactase generates what is known as lactose intolerance. This supposes an inability to metabolize lactose due to a condition in the intestinal microvilli that are responsible for producing lactase.

It is possible to distinguish between permanent intolerance (hereditary and determined by genetics of the individual) and temporary or reversible intolerance (also known as acquired intolerance, is produced by a pathology or a specific situation that can be cured).

In addition to all the above, it is important to know that there are various methods to carry out the diagnosis of what would be lactose intolerance. And is that some cases are difficult to determine and require specific systems to do so.

However, we find the fact that these are the most significant methods in this regard:
• Blood test, through which it is possible to know what the initial blood glucose level is and from there the lactose overload that the person in question has.
• Genetic test. Among the latest systems established to determine the aforementioned intolerance is this one that is increasingly being used for this purpose.
• Hydrogen breath test, which is currently the most widely used method to achieve the fastest, most effective and real results.
• Biopsy of the small intestine. Only in very specific and specific cases is it committed to this other lactose intolerance detection system, which can be performed through endoscopy or esophagogastroduodenoscopy.

The symptoms of lactose intolerance they are warned after ingesting dairy products or foods derived from them. Between these symptom Abdominal cramps, diarrhea, constipation, and skin rashes may be mentioned. As the level of lactase production varies from person to person, the characteristics of lactose intolerance and symptoms are not the same in all cases.

However, there are many other symptoms that indicate that a person suffers from lactose intolerance. Specifically, these include spasms, abdominal bloating, gas, vomiting, nervousness, various sleep disorders, fatigue, difficulty concentrating or fatigue.

The control of the dietTherefore, it is usually done through trial and error tests to determine what foods and in what quantities a subject can ingest without experiencing adverse reactions.
