Possible Causes of Lactose Intolerance

This article “possible causes of lactose intolerance” will be helpful for those who feel heaviness, nausea and vomiting after eating diary products. It is estimated that almost 75% of adults show low lactase activity during adulthood. People experience trouble after eating milk and milk containing products but they are unaware of it.

In this article “possible causes of lactose intolerance” we are going to discuss the symptoms, causes and methods to avoid the lactose intolerance. It will give you knowledge about this common health concern and will help you for self diagnosis of it, if you are suffering with it. In this we especially emphasize on the most possible causes of lactose intolerance.

What is lactose intolerance?

Lactose intolerance is the inability of human digestive system to metabolize lactose. The main cause of this is the inability of digestive system to produce the required enzyme “lactase” to digest lactose (milk sugar).

What are the symptoms of lactose intolerance?

If you feel bad after having dairy products, you should be careful to watch the symptoms of lactose intolerance. People having lactose intolerance often feel uncomfortable after 30 minutes to 2 hours of consuming dairy product. Sometimes these symptoms are of mild range or sometimes they are strong enough that people may need supplemental lactase. Its symptoms include;

• Abdominal pain

• Abdominal gas

• Abdominal bloating

• Diarrhea

• Nausea

What are the possible causes of lactose intolerance?

Now come towards the discussion of possible causes of lactose intolerance; lactose intolerance or Lactase deficiency may have one of the following reasons:

  • Congenital causes of lactose intolerance

It may occur because of a by birth defect or congenital absence of lactase. It occurs due to a nonsense mutation in the gene which is responsible of lactose production. This mutation is very rare and patients with this cause are difficult to thrive. The symptoms of congenital lactose intolerance begin shortly after birth.

  • Secondary causes of lactose intolerance

Another cause among the possible causes of lactose intolerance is any injury to the lining of the small intestine like celiac disease which destroys the lactase producing cells.

  • Developmental causes of lactose intolerance

It is another important point to be mentioned among the possible causes of lactose intolerance. In this condition there is reduction in the production of lactase after childhood which persists in adulthood. Mostly it is of unknown cause but sometimes it is also considered as genetically pre-programmed.

Management of lactose intolerance

After discussion of the possible causes of lactose intolerance, management of lactose intolerance should also be discussed:

• First of all one should avoid lactose-containing products (dairy products) as much as possible.

• Use of Lactase supplementation to avoid the symptoms.

• Rehabituation to dairy products as much a possible.

The above information will be helpful for maximum health care for you.
