How does one become lactose intolerant

Lactose intolerance is a common digestive disorder that affects a significant portion of the world’s population. It is estimated that about 65% of people have some degree of intolerance. So, how does one become lactose ? Let’s delve into the subject and the causes and symptoms of this condition.

To understand lactose intolerance, we must first understand lactose. Lactose is a sugar found in milk and dairy products. In order for our bodies to digest lactose properly, it needs an enzyme called lactase. Lactase breaks down lactose into two simpler sugars, glucose, and galactose, which can then be absorbed into the bloodstream.

Lactose intolerance occurs when the body doesn’t produce enough lactase to effectively digest lactose. This can be a result of various factors, including genetics, age, and certain medical conditions.

The most common cause of lactose intolerance is a genetic mutation that affects lactase production. In some individuals, the body produces less lactase as they grow older, resulting in symptoms of lactose intolerance. This type of lactose intolerance is more prevalent in adults of certain ethnic backgrounds, including those of African, Asian, and Hispanic descent.

Another type of lactose intolerance, known as primary lactose intolerance, can develop after childhood in individuals who previously had no issues digesting lactose. This occurs due to a decline in lactase production as they age.

Secondary lactose intolerance can occur as a result of certain medical conditions or treatments. For instance, damage to the small intestine due to conditions such as celiac disease or bacterial overgrowth can lead to a temporary or permanent decrease in lactase production. In some cases, chemotherapy or radiation therapy for cancer treatment can also trigger lactose intolerance.

Now that we understand the causes, let’s take a look at the symptoms of lactose intolerance. Symptoms typically occur within a few hours after consuming lactose-containing or beverages. Common symptoms include bloating, gas, diarrhea, nausea, and stomach cramps. The severity of these symptoms can vary from person to person, depending on how much lactose they consume and their level of lactase deficiency.

If you suspect that you might be lactose intolerant, it is advisable to visit a healthcare professional. Your doctor may conduct a physical examination, review your medical history, and recommend some diagnostic tests, such as a lactose tolerance test or a hydrogen breath test.

While there is no cure for lactose intolerance, there are several ways to manage the symptoms. The most effective solution is to reduce or eliminate the consumption of lactose-containing foods and beverages. However, many individuals with lactose intolerance can still tolerate small amounts of lactose without experiencing severe symptoms. Lactase supplements are also available over the counter, which can help the body digest lactose.

In conclusion, lactose intolerance is a common condition that develops due to a deficiency in lactase production. It can be caused by genetic factors, age-related decline in lactase production, or certain medical conditions. The symptoms of lactose intolerance can range from mild to severe and can be managed by reducing lactose consumption or using lactase supplements. If you suspect you have lactose intolerance, consult a healthcare professional for accurate diagnosis and treatment options.
