Lactose Intolerance in Adults: Why It Can Develop Later in Life and How to Test for It

Lactose intolerance is commonly seen as a milk or dairy allergy. However, it is not a true allergy, but an inability to break down lactose found in dairy products. Some people know they are lactose intolerant from an early age. However, others develop it later in life. It is totally possible to find out that you have become lactose intolerant in your 40s. This is where lactose intolerance testing steps in.

This article talks about lactose intolerance in adults, why it can develop later in life, and how to test for it.

Understanding Lactose Intolerance

Lactose intolerance develops due to a deficiency in lactase, the enzyme responsible for breaking down lactose. Without enough lactase, lactose moves into the colon instead of being processed and absorbed in the small intestine. The fermentation can lead to uncomfortable symptoms like bloating, gas, and diarrhea.

The Science Behind Adult-Onset Lactose Intolerance

For many, lactose intolerance is influenced by genetics. Some populations have a higher prevalence of lactose intolerance due to historical dietary habits.

For others, lactose intolerance can develop as a secondary condition. This might happen after surgeries or illnesses that affect the small intestine, such as celiac disease or Crohn’s disease.

Additionally, the production of lactase tends to decrease with age, which explains why some individuals only experience lactose intolerance symptoms as adults. This gradual decline can surprise those who have consumed dairy without issues for years.

Recognizing Symptoms and Getting Diagnosed

Lactose intolerance symptoms can vary in severity and can sometimes be mistaken for other gastrointestinal issues.

Common signs include:

• Bloating and gas.
• Diarrhea.
• Stomach cramps.
• Nausea.

If you suspect lactose intolerance, it is important to consult a healthcare provider. They can help differentiate it from other issues like irritable bowel syndrome (IBS) or allergies. A gastroenterologist, or GI doctor, is a specialist in digestive health and can offer guidance.

Managing Your Diet with Lactose Intolerance

Living with lactose intolerance doesn’t mean you have to give up all your favorite foods. Many products are now available to help you enjoy your favorite dairy products:

1. Lactose-Free Alternatives: Many companies offer lactose-free versions of milk, cheese, and yogurt.
2. Enzyme Supplements: Over-the-counter lactase supplements can help you digest lactose if you’re eating out or consuming dairy occasionally.
3. Calcium-rich foods: Incorporate non-dairy sources of calcium, such as leafy greens, almonds, and fortified plant-based milk.

Eating smaller servings of dairy or choosing aged cheeses and Greek yogurt can also reduce symptoms since they typically contain less lactose.

Lactose Intolerance Testing

It is important to get a diagnosis of lactose intolerance. This is because many GI conditions share the same symptoms as the condition.

Your healthcare provider can use a lactose hydrogen breath test to detect hydrogen levels in your body and diagnose your condition. High levels indicate undigested lactose.

Here’s how a lactose hydrogen breath test is done, step by step:

1. Preparation: For accuracy, individuals need to fast for 12 hours before the test. Avoid eating high-fiber foods the day before, as they can affect the outcome.
2. Initial Breath Sample: When you arrive for the test, your first task will be to blow into a small device to provide a baseline breath sample. This measures the initial level of hydrogen in your breath before consuming any lactose.
3. Drinking the Test Sugar: After the baseline sample, you’ll drink a small amount of test sugar, usually something like milk, sugar water, regular soda, or lactulose. This sugar contains lactose, which is the substance being tested for digestion.
4. Breath Samples Over Time: Every 20 minutes over the next 3 hours, you’ll blow into the device to provide additional breath samples. These samples measure the hydrogen levels in your breath, which increase if your body is not properly digesting lactose.
5. Monitoring Symptoms: As the test progresses, be aware of any symptoms like gas, bloating, cramping, or diarrhea, as these are signs of lactose intolerance.

The test helps to determine if your body produces enough lactase, the enzyme needed to digest lactose properly. The result of the test will help your provider determine the best dietary plan and management moving forward.

Discovering lactose intolerance as an adult can be surprising, but with the right information and support, it’s manageable. Consider searching online for lactose intolerance testing near you to find qualified professionals who can assist you.
