Lactose Intolerance

Introduction

Lactose intolerance is a condition where the body is unable to fully digest lactose, a sugar found in milk and dairy products. This intolerance is caused by a deficiency of the enzyme lactase, which is responsible for breaking down lactose into simpler sugars that can be easily absorbed by the body.

Symptoms

Common symptoms of lactose intolerance include bloating, gas, diarrhea, and stomach cramps after consuming dairy products. These symptoms may vary in severity depending on the individual’s level of lactase deficiency.

Diagnosis

Lactose intolerance can be diagnosed through various tests such as the lactose tolerance test or hydrogen breath test. These tests measure the body’s ability to digest lactose and can help determine the severity of the intolerance.

Treatment

The most effective treatment for lactose intolerance is to avoid or limit the consumption of dairy products. There are also lactase supplements available that can help individuals digest lactose more effectively.
