What is Lactose Intolerance?
In lactose intolerance or Lactose maldigestion, our intestine cannot digest lactose present in the milk and milk products. This occurs due to lactase deficiency. If you have lactose intolerance and you eat dairy products, you can get diarrhea, belly pain, bloating and gas. Lactose intolerance can affect anyone. But it is most common among Native American, Asian, Asian Indians, and black people.
How common is Lactose Intolerance?
Approximately 60 to 70 per cent of people in India are lactose intolerant. The frequency is higher among healthy populations from southern India than from northern India. The lower frequency in the north Indians is apparently due to the fact that they are descendants of the Aryans who have been dairying for long and are known to be lactose tolerant. So, the genetic mixing is responsible for greater lactose tolerance amongst them.
Europeans have higher percentage of lactose absorption in the whole world. People of African, Asian, African-American have lower frequency of lactose absorption and are most likely to be affected at an earlier age. The absorption capacity goes on decreasing as we grow up. It is least in old age.
What causes Lactose Intolerance?
Lactose intolerance occurs when the small intestine does not produce enough lactase. Lactase is required to digest lactose in the diet. Lactose intolerance generally develops in individuals as they age. People tend to become lactose intolerant around their teenage years, or during adulthood.
If your parents have lactose intolerance, it is very likely that you may too suffer from same. Lactose Intolerance runs in our genetics. Lactose intolerance can also be brought on by infection of intestine (gastroenteritis, rota virus infection), chemotherapy, surgery, or from the avoidance of dairy products for a prolonged period of time.
