Overview

Millions of individuals worldwide suffer from lactose intolerance, a digestive ailment. It results from the body's inability to completely digest the sugar lactose, which is present in milk and other dairy products. While consuming meals containing lactose, those with lactose intolerance experience various symptoms, such as bloating, gas, and diarrhoea. This blog will discuss lactose intolerance's causes, symptoms, diagnosis, and available treatments.

Causes of Lactose Intolerance

Lack of lactase, an enzyme made by the cells lining the small intestine, causes lactose intolerance. Lactase converts lactose into glucose and galactose, two simple sugars that can enter the bloodstream. Lack of lactase results in lactose remaining undigested and moving into the large intestine, where it interacts with bacteria and causes digestive symptoms.

Three kinds of lactose intolerance exist:

Primary lactose intolerance is the most prevalent form of the condition and is brought on by a decline in lactase production with advancing age. Up to 75% of the world's population is impacted.
Secondary lactose intolerance: This occurs when the lack of lactase is brought on by another ailment, such as chemotherapy, celiac disease, or Crohn's disease.
Congenital Lactose Intolerance: The rare genetic condition known as congenital lactose intolerance, which affects infants and children, is defined by a complete lack of lactase.

Symptoms of Intolerant to Lactose

After eating meals containing lactose, symptoms of lactose intolerance can appear between 30 minutes and two hours later. The most typical signs are as follows:

Continent pain
Bloating
Bloating
Diarrhoea
Nausea
Vomiting

Moreover, some people may develop muscle weakness, weariness, and headaches.

Diagnosis of Lactose Intolerance

Your doctor could run one or more tests if you think you have lactose intolerance. These tests consist of the following:

Lactose tolerance test: A lactose tolerance test checks the blood glucose levels after ingesting a lactose solution.
Hydrogen breath test: When someone consumes a lactose solution, a hydrogen breath test determines how much hydrogen is in their breath. It helps diagnose SIBO or small intestine bacterial overgrowth and lactose intolerance.
The stool acidity test gauges how much acid remains in the stool after drinking a lactose solution.

Options for Treating Lactose Intolerance

The severity of the symptoms and the underlying cause of lactose intolerance will determine the best course of treatment. Here are a few possibilities:

Elimination of foods containing lactose: Excluding foods containing lactose, such as milk, cheese, and yoghurt, is the easiest and most successful strategy to treat lactose intolerance. Dairy products with reduced or no lactose content are also offered.
Lactase enzyme supplements: Supplemental lactase enzymes can be administered orally to aid in the body's digestion of lactose before eating meals that contain it. These supplements are offered as liquid, pills, or capsules.
Probiotics: Live bacteria known as probiotics are available as nutritional supplements or in foods that have undergone fermentation, such as yoghurt, kefir, and kimchi. They may help improve gut health and reduce lactose intolerance symptoms.
Alternative milk options: Numerous non-dairy milk options are naturally lactose-free, including almond milk, soy milk, and oat milk.

Living with Lactose Intolerance

Although managing lactose intolerance can be difficult, enjoying a varied and balanced diet is still feasible. Here are some pointers for managing lactose intolerance:

Read food labels: Check food labels carefully before purchasing or consuming any product because many processed foods contain lactose.
Try lactose-free and low-lactose dairy products: a variety of these items on the market can be used instead of ordinary dairy products.
Contact a qualified dietitian: They can assist you in creating a nutritious diet that satisfies your needs while avoiding foods that contain lactose.
Use caution while consuming calcium: Individuals who are lactose intolerant may need calcium supplements to ensure they are getting adequate calcium for strong bones.
Don't be afraid to ask for alternatives: While dining out or attending social gatherings, don't hesitate to ask for lactose-free options or substitutes.

FAQ's

Q. How is lactose intolerance treated, and what causes it?
A. The body's inability to create enough lactase, an enzyme that aids in digesting lactose, the sugar in milk and dairy products, causes lactose intolerance. Bloating, gas, and diarrhoea can indicate that lactose is not adequately absorbed. The best ways to treat lactose intolerance are to limit or avoid lactose-containing foods and drinks, take lactase supplements before consuming dairy products, incorporate probiotics in your diet, and switch to non-dairy milk. Although no known treatment for lactose intolerance exists, these solutions can help people manage their symptoms and enjoy a balanced diet.

Q. What foods should someone who is lactose intolerant avoid?
A. Avoiding or limiting your intake of foods and drinks that contain lactose is vital if you have lactose intolerance. This applies to dairy products, including milk, cheese, ice cream, and yoghurt. Read food labels carefully because processed foods may potentially contain lactose. Regarding lactose intolerance, some people may be able to tolerate small amounts, while others may need to avoid it completely. Non-dairy milk options, lactose-free dairy products, and other calcium sources such as leafy greens, tofu, and fortified foods are alternatives to foods containing lactose.

Q. Which medical term best describes lactose intolerance?
A. The most accurate diagnostic for lactose intolerance is a hydrogen breath test. Doctors use this test to identify lactose intolerance and lactose malabsorption. Your breath typically contains a small amount of hydrogen, a particular gas. Undigested lactose contributes to lactose malabsorption, which results in excessive hydrogen levels in the breath.
