Does Lactose Intolerance Go Away? How Do You Fix Lactose Intolerance?


Lactose intolerance involves difficulty digesting lactose, a sugar in dairy. Symptoms, like bloating, gas, and diarrhea, arise post-dairy consumption. It is due to lactase enzyme deficiency. This condition is more common in adults and some ethnicities. It doesn’t cause harm, but it can be uncomfortable. Severity varies; some tolerate limited lactose.

Diagnosis typically relies on symptoms and tests. Managing it requires following lactose-reduced diets. It also involves taking lactase enzyme supplements. Besides, you need to find more sources of calcium and vitamin D. Changing your diet can effectively relieve symptoms. This article explores lactose intolerance, its symptoms, causes, diagnosis, and prevention. 

What Is Lactose Intolerance? Why Am I Suddenly Lactose Intolerant?

Lactose intolerance is a common digestive disorder. The body struggles to process lactose, a sugar in milk. Lactose is found in milk and dairy products. Differentiating lactose intolerance from a milk allergy is crucial. Lactose intolerance is a digestive issue. A milk allergy involves the immune system’s response to milk proteins.

Key Insights

  • Lactose intolerance is a disorder caused by challenges in digesting lactose found in dairy.
  • It’s distinctly different from a milk allergy, an immune system reaction. This condition is commonly observed worldwide, with varying intensities. 

Individuals may experience symptoms ranging from mild discomfort to severe digestive disturbances.

Symptoms And Causes Of Lactose Intolerance

Lactose intolerance is a condition characterized by symptoms such as bloating, diarrhea, gas, nausea, and abdominal pain, resulting from lactose malabsorption, where the small intestine cannot digest all the lactose in food or drink.

Symptoms Of Lactose Intolerance

Lactose intolerance symptoms differ in individuals based on the quantity consumed. The most common symptoms include:

  • Bloating: This includes feelings of fullness and gassiness post-dairy consumption.- Diarrhea: Characterized by loose, watery stools following the intake of dairy products.
  • Abdominal Pain: Refers to cramps and discomfort in the stomach area.
  • Nausea: This may include feelings of sickness and the urge to vomit after consuming dairy.
  • Flatulence: Excessive gas production is a frequent symptom. These symptoms generally appear a few hours after consuming foods or drinks containing lactose.

Causes Of Lactose Intolerance

Lactose intolerance results from insufficient lactase, an enzyme in the small intestine. Lactase breaks down lactose into absorbable sugars. When lactase is deficient, lactose stays undigested in the gut, leading to the symptoms associated with this condition. 

Interesting Aspects

  • Genetic factors often play a role in lactase deficiency, indicating a hereditary pattern.
  • Certain health conditions, like Crohn’s disease, can induce secondary lactose intolerance. 

Diagnosis And Testing Procedures Of Lactose Intolerance

Suspected lactose intolerance can be confirmed through specific diagnostic tests. The two main tests include:

Lactose Tolerance Test: To complete this test, you will drink a liquid with lactose. Then, we will measure your blood sugar levels regularly. A lack of significant rise in blood sugar levels suggests inadequate lactose digestion.

Hydrogen Breath Test: After ingesting a lactose solution, the patient’s breath is analyzed for hydrogen gas levels. Higher than normal hydrogen levels are indicative of lactose intolerance. 

Theoretical Explanation Of Diagnostic Tests

Lactose Tolerance Test

  • Method: Involves measuring blood sugar levels after drinking a lactose solution.
  • Indication: If blood sugar levels do not increase as expected, the body is not effectively breaking down lactose. This could indicate a possible diagnosis of lactose intolerance. 

Hydrogen Breath Test

  • Method: This test measures the amount of hydrogen in the breath after the patient consumes lactose
  • Indication: Elevated hydrogen levels in the breath indicate lactose intolerance. The high levels show that lactose is not being digested properly.

Management And Treatment Options Of Lactose Intolerance

Management And Treatment Options Of Lactose Intolerance

Dietary Adjustments 

Effectively handling lactose intolerance often involves changing your diet. Here are some straightforward strategies:

  • Cut Back on Dairy: Try to reduce or completely avoid dairy products that are high in lactose. This includes items like regular milk, ice cream, and some cheeses. Lower your intake of these foods. It can reduce lactose intolerance symptoms.
  • Choose Lactose-Free Alternatives: There are many lactose-free options available now. These include lactose-free milk and dairy substitutes. These products taste like regular dairy but are lactose-free to prevent discomfort. Switching to these can help you enjoy dairy-like products without the side effects.
  • Take Lactase Supplements: Consider lactase enzyme supplements if you want to eat dairy. These supplements help your body break down lactose. Take them before you eat or drink dairy to help prevent symptoms. Over the counter, they can manage lactose intolerance effectively.

Lifestyle Changes 

Additional lifestyle modifications can help manage this condition:

  • Incremental Lactose Introduction: Some individuals can tolerate small amounts of lactose. It’s beneficial to experiment and determine your threshold.
  • Reading Product Labels: Dairy or lactose can be hidden ingredients in many processed foods, so label reading is crucial.
  • Nutritional Guidance: Consulting a registered dietitian can help plan a balanced, lactose-free diet.

Preventive Strategies Of Lactose Intolerance

Preventive Strategies Of Lactose Intolerance
  • Adopt a Lactose-Free Diet: Prioritizing foods and drinks without lactose is the cornerstone of managing lactose intolerance. To avoid dairy, skip milk, cheese, and yogurt and choose lactose-free options. 
  • Incorporate Lactase Supplements: Taking lactase enzyme supplements before consuming dairy helps digestion. This is especially beneficial for people who want to consume dairy products. 
  • Explore Dairy Alternatives: Today, you have many non-dairy options. These include almond, soy, oat, and rice milk. You can also find vegan cheese and yogurt. These products provide similar textures and flavors without lactose. 
  • Manage Calcium and Vitamin D Intake: Individuals who are lactose intolerant should ensure they consume sufficient amounts of calcium and vitamin D. Dairy products serve as a primary source for these nutrients, but alternative options and supplements are available. 
  • Small Portions and Testing Tolerance: Some people with lactose intolerance can handle small amounts of lactose. Observing the body’s reaction, gradually introduce small servings of dairy. This can help determine personal tolerance levels. 
  • Consult a Dietitian: A dietitian can offer tailored guidance. They can assist in creating a well-rounded, nutritious meal plan. This plan will account for the absence of dairy products.
  • Stay Informed About New Products and Research: The food industry is always changing. New lactose-free products and research emerge regularly. Staying informed can open up more dietary options. 

Individuals with lactose intolerance can effectively manage their condition. Implementing these strategies helps minimize discomfort and maintain a healthy diet. They can achieve this by following a balanced approach.

Final Thoughts

Managing lactose intolerance requires changes in diet and lifestyle. This includes avoiding dairy products that contain lactose. Instead, choose lactose-free or reduced-lactose options. Lactase supplements can help digest lactose. Take them before eating dairy. Eating small amounts of dairy may be okay for some. It’s important to find out what works for you.

Also, get enough calcium and vitamin D from other foods or supplements. Regular check-ups with healthcare professionals are important. They can help diagnose and manage lactose intolerance. With the right strategies, you can avoid digestive discomfort.
