Lactose Intolerance - Symptoms, Diagnosis, Treatment, and FAQ

Lactose Intolerance

Lactose intolerance is a frequently seen digestive disorder that impacts people all over the world. It is characterized by an inability of the body to digest lactose, a type of sugar that's present in milk and other dairy products. This medical condition is triggered by a lack of lactase, an enzyme produced by the small intestine that is accountable for breaking down lactose into simpler molecules that the body can absorb.

Lactose intolerance can occur at any age and is estimated to impact up to 50-60% of the population worldwide. The seriousness of symptoms, however, varies greatly from person to person, and some people may be able to take in small amounts of lactose without going through any negative effects. The causes, symptoms, diagnosis, and treatment options for lactose intolerance will be discussed in this blog post.
Causes of Lactose Intolerance / What are the Different Types of Lactose Intolerance:

Lactose intolerance develops when the body's ability to produce lactase, the enzyme that is accountable for breaking down lactose, is compromised. Lactose intolerance is classified into three types, each with its own cause:

1. Primary Lactose Intolerance: This is probably the most common kind of lactose intolerance, which is caused by a decrease in the production of lactase as we get older. The majority of people with this type of lactose intolerance can consume small amounts of lactose without experiencing any side effects.

2. Secondary Lactose Intolerance: This kind of lactose intolerance can be triggered by small intestine damage, that may arise as a result of celiac disease, Crohn's disease, or chemotherapy. Lactose intolerance is usually temporary in these cases and may improve as the root cause of the problem is treated.

3. Congenital Lactose Intolerance: This is an extremely uncommon genetic condition in which a baby is born with no or only a small amount of lactase enzyme. This type of lactose intolerance is typically diagnosed in childhood and necessitates avoiding all lactose-containing foods.
Symptoms of Lactose Intolerance:

Lactose intolerance symptoms differ from person to person and are dependent on the amount of lactose consumed. Among the most common symptoms are:
 
  • Abdominal pain and cramps
  • Bloating
  • Diarrhea
  • Gas
  • Nausea
  • Vomiting
Lactose-containing foods or beverages can cause symptoms 30 minutes to 2 hours after consumption. In certain situations, the symptoms are mild and require no treatment, whereas, in others, they are severe and have a negative impact on one's quality of life.
What Are the Risk Factors for Lactose Intolerance?

The following factors can increase your or your child's susceptibility to lactose intolerance:
 
  • Lactose intolerance typically manifests itself in adulthood. In babies and young children, the condition is rare.
  • Lactose intolerance is especially prevalent in African, Asian, Hispanic, and American Indian people.
  • Lactase levels may be lower in premature babies because the small intestine does not develop lactase-producing cells until late in the third trimester.
  • Bacterial overgrowth, celiac disease, and Crohn's disease are all small intestine issues that can lead to lactose intolerance.
  • You are more likely to develop lactose intolerance if you have had radiation therapy for stomach cancer or if you have had intestinal complications from chemotherapy.
Diagnosis of Lactose Intolerance / How Lactose Intolerance is Diagnosed?

If you fear that you are suffering from lactose intolerance, you should see your doctor for a proper diagnosis. The following are the most commonly used tests to diagnose lactose intolerance:

A. Lactose Intolerance Test: This test involves taking in a lactose solution followed by measuring the levels of glucose in the blood. If lactose is not broken down, glucose levels remain low.

B. Hydrogen Breath Test: The hydrogen levels in the breath are measured after drinking a lactose solution. Lactose ferments in the gut if it is not broken down, generating hydrogen gas that might be identified through the breath.

C. Stool Acidity Test: This test is commonly used in young children and infants to determine lactose intolerance. After eating lactose-containing foods, the acidity of the stool is measured.
Treatment of Lactose Intolerance / What are the Treatment Options for Lactose Intolerance?

The best treatment for lactose intolerance is to refrain from lactose-containing foods and drinks. This can be difficult because lactose is present in several everyday food items, such as milk, cheese, yogurt, ice cream, and baked goods. There are, however, numerous lactose-free substitutes available, such as milk produced from plants, lactose-free dairy products, and dairy-free foods.

People with lactose intolerance might be capable of consuming tiny amounts of lactose despite going through adverse reactions in certain situations. This can be determined through a trial-and-error process in which people gradually raise the amount of lactose in their daily meals until they reach their tolerance level.

Lactase supplements are an additional option for people who are lactose intolerant. Supplements like these contain the lactase enzyme and should be taken before eating or drinking lactose-containing foods or beverages to help digestion. However, not all lactase supplements have been produced equally, and it is critical to discuss them with your physician before using any supplements.
What are the Lactose-Free Dairy Alternatives?

Lactose-Free Milk: Lactose-free milk is made by combining regular milk with lactase enzyme, which breaks down lactose into simpler sugars that are easier to digest.

Plant-Based Milk: Soy milk, almond milk, rice milk, oat milk, and coconut milk are just a few of the vegan milk options. These lactose-free milk alternatives can be fortified with calcium, vitamin D, and other nutrients.

Lactose-Free Yogurt: Lactose-free yogurt contains the same probiotics and nutrients as regular yogurt and is made from lactose-free milk.

Cheese: Some cheeses, such as cheddar, Swiss, and Parmesan, are naturally low in lactose and can be taken in limited quantities by lactose-intolerant people. These hard cheeses are made by fermenting milk, which lowers the lactose content. There is also lactose-free cheese available.

Ice cream: Lactose-free ice cream is made with lactose-free milk and is available in most supermarkets. Non-dairy ice cream alternatives include soy, coconut, and almond milk-based ice creams.
Final Words:

Lactose intolerance is a widespread digestive disorder that affects millions of individuals around the world. While avoiding lactose-containing foods and beverages can be difficult, there are numerous lactose-free choices available, and people who are lactose intolerant can still eat a diet that is balanced and healthy.

If you suspect you have lactose intolerance, see your doctor right away for a precise diagnosis and personalized treatment plan. Individuals with lactose intolerance can live a healthy and symptom-free life if they are properly managed.
