Laxatives: Friend Or Foe For Lactose Intolerance?

Constipation is not a typical symptom of lactose intolerance, and in fact, lactose intolerance can lead to diarrhoea. However, some laxatives contain lactose, so they are not recommended for people with lactose intolerance. If you are experiencing constipation and suspect you may be lactose intolerant, you should consult your doctor. They may recommend a low-lactose diet or other treatments to manage your symptoms.

Some laxatives contain lactose

Lactulose is broken down in the large intestine, increasing the water content in the stool, which makes it easier to pass. It is available in liquid or pill form and is usually taken once a day for constipation. It can also be used to treat liver disease. If you are taking lactulose, it is important to be aware of the potential side effects, which include gas, bloating, burping, stomach rumbling, nausea, and cramps. If you experience any of these symptoms, or if your condition worsens, it is important to consult your doctor or pharmacist.

It is worth noting that not all laxatives contain lactose, and there may be alternative treatments suitable for people with lactose intolerance. Before taking any laxative, it is recommended to consult a healthcare professional, especially if you have a medical condition such as lactose intolerance or other bowel problems. They can advise on the most appropriate treatment option and provide guidance on dosage and potential side effects.

Additionally, there are other ways to manage constipation that do not involve the use of laxatives. Increasing water intake, consuming more fibre, and making dietary and lifestyle changes can also help relieve constipation.

Lactose intolerance is not typically linked to constipation

Lactose intolerance occurs when the small intestine does not produce enough lactase, the enzyme that digests lactose, a sugar found in milk and other dairy products. As a result, the sugar passes through the gut undigested, leading to the fermentation of bacteria, which causes gas and loose stools.

While lactose intolerance can cause gastrointestinal issues, it is not typically associated with constipation. Constipation is characterised by infrequent bowel movements, hard and/or large stools, painful defecation, and faecal incontinence. In contrast, the symptoms of lactose intolerance include diarrhoea, bloating, abdominal pain, flatulence, and less frequently, nausea and vomiting.

In rare cases, constipation can be a symptom of lactose intolerance. Research suggests that in approximately 30% of cases, constipation can be present. However, this is more common in individuals who are hydrogen non-producers.

If you are experiencing constipation, it is important to consult a healthcare professional to determine the underlying cause.

Lactose intolerance can be diagnosed through a breath or blood test

If you are experiencing symptoms of lactose intolerance, such as gassiness, abdominal pain, cramps, and diarrhea, your doctor may recommend a lactose intolerance test to confirm the diagnosis. This test can be done through a breath test or a blood test.

The hydrogen breath test is the most common way to test for lactose intolerance. It measures the amount of hydrogen in your breath before and after consuming a liquid containing lactose. The test typically takes about two hours to complete. During the test, you will be asked to drink a lactose-containing beverage, which may cause some discomfort if you are lactose intolerant. Starting 15 minutes after drinking the beverage, you will blow into balloon-like bags every 15 minutes for two hours. These samples are then tested for hydrogen levels. Normally, very little hydrogen is present in the breath, but if your body struggles to break down and absorb lactose, the levels of hydrogen in your breath will increase.

The glucose blood test is another method to diagnose lactose intolerance. This test involves taking a series of blood samples before and after consuming a liquid containing lactose. A health care professional will collect the blood samples from a vein in your arm using a small needle. The blood samples will be taken at specific intervals, typically 30 minutes, one hour, and two hours after consuming the lactose-containing liquid.

Both the breath and blood tests are used to help diagnose lactose intolerance by measuring your body's ability to break down and absorb lactose. If you are experiencing symptoms of lactose intolerance, consult with your healthcare provider to determine if a lactose intolerance test is appropriate for you.

Lactose intolerance can be caused by an underlying condition

Lactose intolerance is when the body does not produce enough of the enzyme lactase, which helps digest the sugar (lactose) found in milk and other dairy products. This can lead to uncomfortable symptoms such as tummy pain, diarrhoea, bloating, and nausea. While lactose intolerance on its own is usually harmless, it can be caused by an underlying condition, and it is important to identify and address these causes to manage the intolerance effectively.

There are three types of lactose intolerance, each with different causes. Primary lactose intolerance, the most common type, occurs when lactase production decreases sharply by adulthood, making milk products difficult to digest. This type is often influenced by genetics and is more common in people of African, Asian, Hispanic, and American Indian descent.

Secondary lactose intolerance is the second type and is caused by an injury, illness, or surgery involving the small intestine. This can include intestinal infections, bacterial overgrowth, Crohn's disease, or treatments such as medicines, surgery, or radiation therapy for other conditions. Treating the underlying disorder may help restore lactase levels and improve symptoms over time.

The third type, congenital or developmental lactose intolerance, is rare. It occurs when babies are born with a lack of lactase due to a genetic disorder inherited from both parents. This type of intolerance can also affect premature infants as their small intestines may not yet produce enough lactase.

In addition to these specific causes, certain factors can increase the risk of developing lactose intolerance. These include increasing age, as lactose intolerance typically appears in adulthood; premature birth, as mentioned earlier; and diseases or conditions affecting the small intestine, such as bacterial overgrowth, Crohn's disease, or celiac disease. Certain cancer treatments, such as radiation therapy or intestinal complications from chemotherapy, can also increase the risk of developing lactose intolerance.

If you suspect lactose intolerance, it is important to consult a healthcare professional. They can advise on appropriate tests and help identify any underlying conditions that may be contributing to the intolerance. Treating or managing these underlying causes can be crucial in improving lactose intolerance symptoms and maintaining overall digestive health.

Lactose intolerance can be managed through diet

Lactose intolerance is a reaction in your digestive system to lactose, the sugar in milk. It causes uncomfortable symptoms after you eat dairy products. Many people have difficulty digesting lactose, but not everyone experiences noticeable symptoms. Lactose intolerance occurs in people who lack the enzyme they need to break down lactose.

• Drink small amounts of milk at a time and have it with meals.
• Add milk and milk products to your diet gradually and see how you feel.
• Try eating yogurt and hard cheeses, which are lower in lactose than other milk products.
• Use lactase products to help digest the lactose in milk and milk products.

You can also find lactose-free and lactose-reduced milk and milk products in most grocery stores. These products are just as healthy for you as regular milk and milk products.

If you are lactose intolerant, make sure you get enough calcium and vitamin D each day. Milk and milk products are common sources of calcium, but many other foods that do not contain lactose are also sources of calcium. These include:

• Fish with soft bones, such as canned salmon or sardines.
• Broccoli and leafy green vegetables.
• Almonds, Brazil nuts, and dried beans.
• Products with labels that show they have added calcium, such as some cereals, fruit juices, and soy milk.

Vitamin D is typically supplied in fortified milk. Eggs, liver, and yogurt also contain vitamin D, and your body makes vitamin D when you spend time in the sun.
