Can you develop lactose intolerance at 17?
You can develop lactose intolerance at any age. It could be triggered by a condition, such as Crohn’s disease or gastroenteritis. This can result in your small intestine producing an inadequate supply of lactase.
Why did I suddenly become lactose intolerant?
It’s possible to become lactose intolerant all of a sudden if another medical condition—such as gastroenteritis—or prolonged abstinence from dairy triggers the body. It is normal to lose tolerance for lactose as you age.
Can lactose intolerance run in families?
Primary lactase deficiency is the most common cause of lactose intolerance worldwide. This type of lactase deficiency is caused by an inherited genetic fault that runs in families.
Can you develop lactose intolerance at any age?
You can develop lactose intolerance at any age. It could be triggered by a condition, such as Crohn’s disease or gastroenteritis. This can result in your small intestine producing an inadequate supply of lactase.
What are the most common types of lactose intolerance?
Primary lactose intolerance is the most common. Your lactase production starts to decrease as you age and you become less dependent on dairy, usually after the age of 2. You may not notice symptoms, however, until you’re an adult. It may seem like lactose intolerance has developed, but primary lactose intolerance is hereditary.
Why did lactose tolerance evolve so quickly?
Scientists may never discover the reason why adult lactose tolerance evolved so quickly. Other researchers have suggested that fresh milk provided a more pure fluid alternative to contaminated water sources in arid environments; that milk fat gave people a fertility advantage; or that milk drinking might have been associated with social prestige.
What is the difference between congenital and Developmental lactose intolerance?
Developmental lactose intolerance may occur in premature babies and usually improves over a short period of time. Congenital lactose intolerance is an extremely rare genetic disorder in which little or no lactase is made from birth.
