Lactose Intolerance in Kids and Adults | Diet for Lactose Intolerant

Lactose Intolerance is a disease in which our body is incapable of digesting lactose (a sugar found in milk), thus causing pain in stomach after consuming milk. Here betterhealthfacts.com will bring the complete information about this medical condition. The best way to fight with Lactose Intolerance is to have complete knowledge about it and having proper diet that doesn't hurt you.


What is Lactose Intolerance ?


Our body have different enzymes in different parts of digestive tract to digest different items in our food. One such engyme is "Lactase", which digests lactose. Lactose is a sugar and lactase breaks it down into glucose and galactose, which are absorbed into our blood stream. If it remains undigested in small intestine, then bacteria in large intestine try to break it down and releases hydrogen as a byproduct. This hydrogen causes pain in our stomach region and the patient feels cramps in his/her stomach.

Types of Lactose Intolerance

Lactose Intolerance is of three types. Before we tell you these types, its necessary to know the lactase engyme. In a normal person lactase levels are high at the time of birth, as we need it to digest the milk. Milk is the primary source of nutrition for infants and lactase helps in digesting it. As we grow, we start to eat other food items as well and the lactase level gradually deceases, but it remains sufficient to digest normal input of milk. Now we can tell you the types of Lactose Intolerance.

  • Primary Lactose Intolerance: Its the most common type of Lactose Intolerance. In this type a person is born with sufficient levels of lactase, but its level decreases at a rapid rate and by the time the person reaches adulthood, he/she becomes Lactose Intolerant.
  • Secondary Lactose Intolerance: Sometime as a side effect of some illness, injury or surgery of intestine, the lactase production decreases heavily and the person develops the symptoms of lactase intolerance. It can be treated by treating the primary illness or injury, but it takes time to recover and rise lactase level.
  • Congenital Lactose Intolerance: Its the worst and least found lactose intolerance. When a child is born with lactose intolerance then its Congenital Lactose Intolerance. Its a genetic disorder and such genes come from both father and mother.

Risk Factors for Lactose Intolerance

  • Genes play the most important role. It may come from any of the parents.
  • Increasing age is the second factor. As we age the production of lactase decreases gradually.
  • Injury or Illness of Intestine can decrease the lactase production.
  • Premature birth can also cause Lactose Intolerance as Small Intestine develops in the the third trimester. 

Symptoms of Lactose Intolerance


  • Watery Stools with pain in abdominal region
  • Some kids and adults may feel just uncomfort or pain in abdominal region after a lactose-rich diet.
  • Some occasional symptoms are muscle pain, headache and constipation
