What is lactose intolerance

Basically, lactose intolerance is a disorder of the digestive system and is caused when the body cannot digest the main carbohydrate in dairy products (lactose) leading to various symptoms that include bloating, diarrhea and abdominal cramping. Another reason for lactose intolerance symptoms is that people that have the condition stop producing sufficient amounts of the enzyme lactase that the body needs to digest lactose, a blood test for lactose intolerance will check for

Lactose consists of two sugars (disaccharides) split into two molecules each of the simple sugars galactosemia and glucose, when there is insufficient lactase and that causes lactose to move through the gut in undigested form and that’s where the symptoms of lactose intolerance begin. The enzyme lactase is important because it breaks down lactose into glucose and galactose that are then absorbed in the bloodstream and converted into energy.

What causes lactose intolerance?

To understand the causes of lactose intolerance its important to point out that there are two types and the cause are different in each type, the most common type is primary lactose intolerance and is caused by a reduction in lactase production mostly caused by aging, the decrease in lactase production means that lactose is poorly absorbed, other reasons could be genetic.

The second type of lactose intolerance is known as secondary lactose intolerance this is caused by illness like a stomach bug or more serious celiac disease, the cause is gut inflammation leading to a temporary reduction in lactase production, if the condition isn’t managed in the right way it can lead to some severe problems in the digestive system that include:

  • Abdominal cramps
  • Bloating
  • Diarrhea
  • Gas

People with the condition have also complained of an urgent need to get to a toilet, vomiting, nausea, lower belly pain and kn occasion constipation, undigested lactose in the small intestines causes diarrhea leading to making water move into the digestive tract. When the lactose reaches the colon it is fermented by gut bacteria forming gas and short chain fatty acids leading to pain, bloating and flatulence, how severe the symptoms are will depend on your lactose tolerance and the amount of food that you have eaten.
