Lactose Intolerance

Lactose Intolerance is a common Digestive disorder that affects a large number of people worldwide. It is characterized by the inability to fully digest Lactose, a sugar found in milk and other dairy products.

Pronunciation

Lactose Intolerance is pronounced as /ˈlæk.toʊs ˌɪnˈtɔː.lər.əns/

Etymology

The term "Lactose Intolerance" is derived from the Latin word 'lactis' meaning milk and the English word 'intolerance', indicating an inability to tolerate or digest lactose.

Definition

Lactose Intolerance is a Digestive disorder where the body is unable to fully digest lactose, leading to digestive problems like bloating, diarrhea and abdominal cramps. This condition is caused by a deficiency of the enzyme Lactase which is produced in the small intestine.

Symptoms

The symptoms of Lactose Intolerance can range from mild to severe, depending on the amount of lactase an individual's body makes. Symptoms usually begin 30 minutes to 2 hours after consuming dairy products and can include:

• Bloating
• Diarrhea
• Abdominal cramps
• Gas
• Nausea

Causes

Lactose Intolerance is caused by a deficiency in the enzyme lactase, which is produced by the cells lining the small intestine. Lactase breaks down lactose into two simpler forms of sugar, glucose and galactose, which are then absorbed into the bloodstream.

Diagnosis

Diagnosis of Lactose Intolerance is typically made through a Lactose intolerance test, which measures the body's reaction to a liquid that contains high levels of lactose.

Treatment

While there is no cure for Lactose Intolerance, symptoms can be managed with dietary changes, such as avoiding large servings of milk and other dairy products, using lactase products, and consuming lactose-reduced milk and milk products.
