Understanding Lactose Intolerance

Welcome to Minneapolis Weight Loss Doc, where we provide valuable information on various health conditions. In this article, we will delve into the causes, symptoms, and treatment options of lactose intolerance.

What is Lactose Intolerance?

Lactose intolerance is a common digestive disorder that affects individuals who have difficulty digesting lactose, a sugar found in milk and dairy products. The primary cause of lactose intolerance is a deficiency in the enzyme lactase, which is responsible for breaking down lactose into simpler sugars for easy absorption.

Causes of Lactose Intolerance

Lactose intolerance can develop due to various factors. Firstly, primary lactose intolerance is genetically determined and commonly occurs as individuals age. It is more prevalent in certain ethnic groups such as African, Asian, Hispanic, and Native American populations. Secondary lactose intolerance, on the other hand, can be caused by conditions like celiac disease, inflammatory bowel disease, or certain medications.

Symptoms of Lactose Intolerance

The symptoms of lactose intolerance can vary in severity from person to person. Common signs include:

  • Abdominal pain and bloating: Lactose intolerance may lead to discomfort in the abdominal region, often accompanied by excessive gas and bloating.
  • Diarrhea: Individuals with lactose intolerance often experience loose stools or diarrhea after consuming lactose-containing foods.
  • Nausea and vomiting: Some individuals may experience feelings of nausea or vomiting due to lactose intolerance.
  • Flatulence: Excessive gas production is a common symptom, leading to flatulence or farting.
  • Stomach cramps: Lactose intolerance can cause stomach cramps or spasms, leading to discomfort and pain.

Diagnosing Lactose Intolerance

If you suspect you have lactose intolerance, it is crucial to consult a healthcare professional for an accurate diagnosis. The healthcare provider may recommend several tests, including:

  1. Lactose intolerance test: This test involves drinking a lactose-containing beverage and observing how your body reacts to it. Blood samples may be taken to measure glucose levels, indicating how well your body is digesting lactose.
  2. Hydrogen breath test: This non-invasive test measures the amount of hydrogen exhaled in your breath after consuming lactose. High hydrogen levels may indicate improper digestion of lactose.
  3. Stool acidity test: Infants and young children suspected of lactose intolerance may undergo this test, which measures the acidity of their stool after consuming lactose.
  4. Genetic testing: In some cases, genetic testing may be used to determine the presence of genes associated with lactose intolerance.

Treatment Options for Lactose Intolerance

While lactose intolerance cannot be cured, there are several ways to manage the condition effectively and lead a symptom-free life. Here are some treatment options:

  • Lactase supplements: These over-the-counter supplements contain the enzyme lactase and can be taken before consuming lactose-containing foods or beverages.
  • Lactose-reduced or lactose-free products: Many stores now offer lactose-free alternatives to dairy products, including milk, cheese, and yogurt.
  • Gradual introduction: Some individuals may find it helpful to gradually introduce small amounts of lactose into their diet to build tolerance over time.
  • Dietary adjustments: Working with a registered dietitian can help you identify foods high in lactose and find suitable alternatives.


In summary, lactose intolerance is a digestive disorder caused by a deficiency in the enzyme lactase. It can lead to various uncomfortable symptoms such as abdominal pain, diarrhea, and bloating. If you suspect you have lactose intolerance, it is crucial to consult a healthcare professional for an accurate diagnosis and explore suitable treatment options.
