Lactose intolerance is a condition that affects many individuals. It occurs when the body doesn’t produce enough lactase, an enzyme that breaks down lactose, the sugar found in milk, and other dairy products. Lactose intolerance is prevalent worldwide, affecting up to 75% of the global population. The primary purpose of this article is to help readers identify and manage lactose intolerance symptoms.

Symptom Identification

Lactose intolerance refers to the inability to digest lactose properly. Some common symptoms include:

Gastrointestinal distress:

After consuming lactose-containing foods, individuals may experience bloating, gas, diarrhea, and abdominal pain.

Skin irritations:

Lactose intolerance may manifest as rashes and itching on the skin.

Respiratory symptoms:

In some rare cases, individuals with lactose intolerance may experience wheezing, coughing, and difficulty breathing.

Diagnostic Tests

If you are experiencing any of the symptoms mentioned above, it is essential to see a healthcare provider or gastroenterologist. You need to undergo thorough diagnostic tests to determine whether you have lactose intolerance or not. Some diagnostic tests include:

Breath tests:

In this test, you consume a lactose-containing drink and then breathe into a device that measures the amount of hydrogen in your breath. High levels of hydrogen are an indication of lactose intolerance.

Blood tests:

A blood sample is taken to measure glucose levels after you consume a lactose-containing drink. If your glucose levels don’t increase, it is an indication of lactose intolerance.

Intestinal biopsy:

This test is done by taking a sample of the intestinal lining to determine the amount of lactase enzyme present in your intestines.

Lactose-Free Diet

The most effective way to manage lactose intolerance symptoms is to avoid or limit lactose-containing foods, particularly dairy products. Some tips to follow a lactose-free diet are:

Foods to avoid:

Some dairy products to avoid include milk, cheese, yogurt, butter, and ice cream. Additionally, some foods like bread, pancakes, and cereal mixes may contain lactose.

Alternatives to dairy products:

There are several lactose-free alternatives to dairy products, such as plant-based milk, cheese, and yogurt. However, not all lactose-free alternatives are safe. Some alternatives may still contain lactose in small quantities.

How to determine which lactose-free alternatives are safe:

It’s essential to read food labels carefully to determine which lactose-free alternatives are safe. Some brands may add lactose in small quantities, so it’s vital to be vigilant when purchasing food items.

Food Diary

Keeping track of your food habits is essential to identify lactose intolerance symptoms better. Some vital tips to maintain a food diary include:

How to start:

Choose a notebook or a mobile app that you can use to take pictures, write notes or record voice memos. It’s essential to be consistent and track every meal or snack you consume.

What to track:

Record the number of lactose-containing foods or drinks you consume, including the portion sizes. Also, track the symptoms you experience after consuming lactose-containing food or drinks.

Symptoms to watch for:

Include symptoms such as gas, bloating, diarrhea, nausea, or abdominal pain.


Lactose intolerance is more common in some ethnic groups than others. Some people are genetically predisposed to lactose intolerance. Some tips to learn more about your lactose intolerance predisposition include:

The science behind lactose intolerance:

The ability to produce lactase enzyme depends on the lactase-persistence gene. People with lactose intolerance don’t have the lactase-persistence gene, while people who can tolerate lactose have the gene.

Ways to find out if you’re predisposed to lactose intolerance:

Depending on your ethnic background, you may be more likely to have lactose intolerance. A doctor can help determine your lactose intolerance predisposition with genetic testing.

Other Conditions

Symptoms of lactose intolerance are similar to other medical conditions. It is essential to examine other possibilities if you are experiencing lactose intolerance symptoms. Some conditions to consider include:

Irritable bowel syndrome (IBS):

IBS is a chronic gastrointestinal condition that causes bloating, gas, abdominal pain, and constipation or diarrhea. Some IBS patients may be lactose intolerant as well.

Celiac disease:

Celiac disease is the inability to tolerate gluten, a protein in wheat, barley, and rye. The condition can cause gastrointestinal symptoms similar to lactose intolerance.

Lifestyle Changes

Once you have determined you have lactose intolerance, there are several tips and tricks you can use to help manage symptoms. Some tips include:

Alternative food and drink options:

Try lactose-free dairy products, plant-based alternatives such as almond or soy milk, and lactose-free cheese.

Supplements that aid lactase digestion:

There are several supplements available to aid lactose digestion, including lactase enzyme tablets, which can be taken with meals.

Tips for better quality of life with lactose intolerance:

Make sure to read food labels carefully, plan for lactose-free meals when eating out, and keep necessary medication with you when traveling or outside of the house.


In conclusion, lactose intolerance is a prevalent condition that can be managed with diet and lifestyle changes. It is vital to seek medical advice if you’re experiencing any of the symptoms mentioned above. Managing lactose intolerance symptoms requires dedication and consistency, but the payoff is an improved quality of life.
