Hold Up: Lactose Intolerance Symptoms For Days

Lactose Intolerance

Thats right lactose intolerance symptoms can sometimes last for up to 2 days, although they might resolve much quicker.

In the meantime, drink water to flush your system. And, avoid additional lactose-containing products and excessive raw fruits and veggies. They can contribute to increased gas and bloating when your system is already irritated.

How Do You Prepare For A Lactose Tolerance Test

To prepare for the test, its a good idea to ask your doctor about which test youll be taking and to ask about any dietary restrictions. Your physician may ask that you not eat or drink for 8 hours before the test. Your physician may also restrict your exercise.

Make sure your provider knows about any other conditions you may have and any medications youre currently taking. Some medications and foods can interfere with test results.

Smoking may also affect test results. If youre a smoker, ask your doctor if you should abstain from tobacco prior to taking the test.

Lower The Amount Of Lactose In Your Diet

Many with lactose intolerance can still eat some dairy products without symptoms. Some are able to eat low-fat milk products easier than whole-milk products. It may be possible to increase your tolerance to dairy by gradually adding them to your diet. Minimize your symptoms by:

  • Eating smaller servings. The smaller the serving, the less likely it is to cause symptoms. Try a serving of milk thatâs less than 4 ounces.
  • Have milk with meals. Drinking milk with other foods slows the digestive process. This may reduce symptoms.
  • Add lactase enzyme to milk to break down lactose. Use lactase enzyme tablets or drops. These over-the-counter remedies may help you enjoy dairy without symptoms. Tablets can be taken before a meal or snack, and the drops can be added to a carton of milk. These products donât ease symptoms in everyone who is lactose intolerant.
  • Experiment with dairy products. Different dairy products have different amounts of lactose. Hard cheeses, like Swiss, parmesan, and cheddar have less lactose and donât usually cause symptoms. Ice cream and milk have the most lactose. Ice cream also has a high-fat content, which may allow you to enjoy it without symptoms. Eating cultured milk products may also result in no symptoms because the bacteria used to culture it produces the enzyme that breaks down lactose.

Go Easy On The Coffee

While coffee can stimulate the digestive muscles that cause you to pass stool, its not a miracle cure for constipation symptoms. Thats because too much caffeine may cause dehydration, leading to a painful and hard stool. Because of this, it is best to avoid excessive amounts of food and liquids containing caffeine, including coffee, teas, soft drinks and chocolate.

According to a December 2012 review published in Nursing, its best to focus on increasing your non-caffeinated fluid intake to improve your ability to pass stool without pain. They suggest trying to drink 60 to 80 ounces of water throughout the day.

To increase your water intake, keep a bottle on your desk at work or in the car to remind you to consistently take in fluids. For the more technologically-savvy drinkers, several water drinking apps can track fluid intake and send alerts.

Congenital Or Developmental Lactose Intolerance

Understanding Lactose Intolerance

In very rare cases, lactose intolerance is inherited. A defective gene can be transmitted from the parents to a child, resulting in the complete absence of lactase in the child. This is referred to as congenital lactose intolerance.

In this case, your baby will be intolerant of breast milk. They will have diarrhea as soon as human milk or a formula containing lactose is introduced. If its not recognized and treated early on, the condition can be life-threatening.

The diarrhea can cause dehydration and electrolyte loss. The condition can be treated easily by giving the baby a lactose-free infant formula instead of milk.

Does Lactose Intolerance Always Cause Diarrhea

Lactose intolerance is a condition in which people cant digest lactose, a sugar found in dairy products. Lactose intolerance can cause diarrhea, but it doesnt always do so. In fact, about half of people with lactose intolerance dont experience diarrhea at all.

There are several factors that can influence whether someone with lactose intolerance experiences diarrhea. For example, if the person with lactose intolerance consumes large amounts of dairy products very quickly, they may experience diarrhea because their intestines cant handle the sudden spike in lactose levels. However, even individuals who consume small amounts of dairy regularly may not develop diarrhea if they have a well-functioning digestive system.

So while lactose intolerance is definitely associated with a higher risk of developing diarrheal symptoms, not everyone who has this condition experiences them.

What Is Causing Diarrhea After Eating

Bacteria that cause diarrhea-producing infections include salmonella and E.coli. Contaminated food and fluids are common sources of bacterial infections. Rotavirus, norovirus, and other kinds of viral gastroenteritis, commonly referred to as stomach flu, are among the viruses that can cause explosive diarrhea.

Complications Of Lactose Intolerance

Milk and other dairy products contain calcium, protein and vitamins, such as A, B12 and D.

Lactose also helps your body absorb a number of other minerals, such as magnesium and zinc.

These vitamins and minerals are important for the development of strong, healthy bones.

If you’re lactose intolerant, getting the right amount of important vitamins and minerals can prove difficult.

This may lead to unhealthy weight loss and put you at increased risk of developing the following conditions:

  • osteopenia where you have a very low bone-mineral density left untreated, it can develop into osteoporosis
  • osteoporosis where your bones become thin and weak, and your risk of breaking a bone is increased
  • malnutrition when the food you eat does not give you the nutrients essential for a healthy functioning body this means wounds can take longer to heal and you may start to feel tired or depressed

If you’re concerned that dietary restrictions are putting you at risk of complications, you may find it helpful to consult a dietitian.

They can advise you on your diet and whether you require food supplements.

Your GP should be able to refer you to an NHS dietitian free of charge. Or you can contact a private dietitian.

The British Dietetic Association has information on how to find a private dietitian.

Signs Of Lactose Intolerance And How To Treat It

Everyone loves ice cream, but no one loves the intestinal distress that can happen after eating a bowl of this classic treat. If you have experienced gas, cramping, or diarrhea after eating ice cream or other dairy-rich foods, you may be lactose intolerant.

Those who are lactose intolerant canât fully digest the sugar in milk. This sugar is called lactose. Their inability to digest it results in stomach issues after eating or drinking food and drinks that contain dairy. Lactose intolerance is also called lactose malabsorption. Itâs usually harmless, but the symptoms can be uncomfortable.

Lactose intolerance is usually caused by a lack of an enzyme called lactase. Itâs produced in the small intestine. Some people who produce a small amount of lactase are still able to digest milk products. If levels of lactase are too low, youâll become lactose intolerant and experience symptoms after you eat or drink dairy products. Many people who are lactose intolerance can manage it without giving up all foods with dairy.

Is Dairy Really Bad For You

This is the question that everybody really wants to ask and the answer is this: yes and no. Dairy products have calcium, vitamins and milk protein which host a slew of benefits for humans, especially when theyre young. The fatty acids and fat soluble nutrients found in milk and other dairy products can promote things such as brain growth, bone density, skin health, and digestive system functionality. Of course, if youre lactose intolerant, these benefits do not outweigh the health problems of consuming dairy, especially cows milk. There are many alternatives to dairy foods like lactose free milk. Most any dairy products, even ice cream now have a lactose free option. However, if your digestive tract can handle consuming dairy, then it can be a staple of ones diet. As with anything, however, dairy should be consumed in moderation. Consuming too much can cause digestive problems, not to mention that a high dairy diet can be very fattening if not balanced and coupled with physical activity. As Dr. Gingold says, Dairy does have more fat than many other products. Lactose intolerant people can clearly be affected worse by this, however, dairy is good and encouraged when not overused. So dont be afraid to have a glass of milk or a slice of cheese, just dont over do it!

Lactose is a sugar found naturally in dairy products. It is present in cows milk, but not in human breast milk. Lactose intolerance occurs when the body cannot digest lactose properly. This results in symptoms such as stomach cramps, bloating, gas, nausea, diarrhea, and other gastrointestinal problems. Symptoms usually occur within 30 minutes after consuming milk or milk products containing lactose.

What Is Lactose And How Does It Work

Lactose is a sugar found naturally in milk. It is used in many products such as ice cream, yogurt, cheese, butter, and other dairy products. Lactose is broken down into glucose and galactose during digestion. Glucose is absorbed directly into the bloodstream while galactose is converted into energy. This process is called metabolism.

Causes And Types Of Lactose Intolerance

Lactose is made up of the simple sugars glucose and galactose.

You need the enzyme lactase to break lactose down into glucose and galactose, which your body then absorbs into your bloodstream for energy.

Without sufficient lactase, lactose moves through your gut undigested and causes digestive symptoms. Still, there are multiple causes of lactase deficiency (

1 ):

  • Hydrogen breath test. This test measures hydrogen in your breath after lactose intake. High amounts of hydrogen suggest digestive problems that may be related to lactose intolerance but also caused by other issues.
  • Lactose tolerance test. This test measures your blood sugar after lactose ingestion. If you have lactose intolerance, your blood sugar levels wont be affected because your body cant break down lactose.
  • Genetic test. This test checks for genetic causes of lactose intolerance, but people with secondary lactose intolerance may receive a false negative.
  • Lactase activity at jejunal brush border. This invasive and expensive method requires a biopsy of the jejunal brush border, which is part of your small intestine, but is a definitive way to assess lactase activity.
  • Stool acidity test. Often used for babies and infants, this test measures stool acid levels, which have a lower pH in cases of lactose intolerance .


Your doctor may choose among several tests to check for lactose intolerance. Otherwise, you can try an elimination test yourself.

You Actually Have Some Food Allergies Or Other Intestinal Situations Going On

Food allergies, food sensitivities, and lactose intolerance can all have a ton of overlapping symptoms, which really can make discerning between all of the possibilities quite difficult.

Lactose is only one of the dietary intolerances that should be considered when patients have symptoms of alternating bowel habits or symptoms of GI distress with different foods, Tsynman said. Patients can also consider evaluations for a fructose intolerance, a sucrose intolerance celiac disease, food allergies, infectious causes of irregular bowels, or small intestinal bacterial overgrowth.

Med Talk/Health Talk: Lactose Intolerance

Once lactose intolerant, always lactose intolerant. Thats because the condition is caused by a deficiency of the enzyme lactase, and at least right now, doctors and scientists dont know a way to increase your bodys production of this enzyme.

You might not be totally SOL, though there are over-the-counter lactase tablets that you can take about 30 minutes before eating a meal containing dairy to mitigate symptoms. However, they dont work for everybody.

So, unfortunately, it might be time to kiss your lasagna and dairy ice cream goodbye for good. On the bright side, weve fully entered the era of the milk alternatives, so there are tons of options to choose from.

Lactose Intolerance And Dairy

Its important to note that nearly 50 million Americans show signs of lactose intolerance, even more dont even realize that theyre lactose intolerant. So what is lactose, anyway? Lactose is actually a type of sugar that occurs naturally in the milk of most mammals, including the most common American milk producer: cows. Within humans exists an enzyme called lactase, which is the enzyme that breaks down and digests lactose. This enzyme generally deteriorates and lessens as time progresses so that by the time they reach adulthood, the majority of people lack the proper enzyme to digest lactose, making them lactose intolerant. Over-consumption of dairy products can actually cause those lactase enzymes to deplete faster as they are being overworked. Signs of lactose intolerance includestomach bloating, gas, stomach pain, nausea, and diarrhea after consuming dairy products. Some experts believe that a break from dairy products, followed by gradual introduction of them back into your diet can actually promote lactase production, however studies arent entirely conclusive.

How To Prevent Diarrhea Caused By Lactose Intolerance

Lactose intolerance is not curable, but this does not mean it is not manageable. There are several ways to control your symptoms and avoid triggers. You may need to try a variety of techniques before finding the one that works for you.

1. Reduce Intake of Milk and Milk Products

The average person can have a daily amount of 10 g of lactose, so you should consume fat-free, skim, and low-fat milk that contain less lactose. You can also consider eating cheddar cheese which has only 0.9 g of lactose per serving. Experiment with a little bit at first to see how you react.

2. Consume Milk and Milk Products with Other Foods

Sometimes something as simple as consuming milk or milk products with another type of food will counteract lactose intolerant symptoms. For example, eating oatmeal with milk, or cheese with bread may alleviate the severity of your bodys reaction.

3. Eat or Drink Milk and Milk Products in Small Amounts

Instead of chowing down on a big hunk of cheese and washing it down with a tall glass of milk, consider eating small amounts of milk products throughout the day. Often, lactose intolerant people will find this eliminate symptoms.

4. Consider Products with Reduced Lactose

5. Replace Milk and Milk Products with Other Foods

There are several substitutes available, such as nondairy creamers, soy milk, almond milk, soy cheese and tofu. The thing to note is these products often do not have the same nutritional benefits as milk.

6. Take Lactase Supplements

What To Do If You Have Symptoms

Because the symptoms of lactose intolerance are rather general, it is important to get an accurate diagnosis before removing dairy from your diet .

In fact, many people who think they have lactose intolerance because theyâve experienced the symptoms have been shown to absorb lactose normally.

Health care providers often diagnose lactose intolerance using the hydrogen breath test. This involves ingesting 1.8 ounces of lactose and testing for elevated levels of hydrogen in the breath, which are caused by bacteria fermenting lactose in the colon (

, 8).

This is because not all people with malabsorption have lactose intolerance.

Lactose intolerance is defined by the presence of reported symptoms, and that depends on how sensitive a person is to the effects of malabsorption, as well as the amount of lactose in their diet .

Treatment of lactose intolerance usually involves restriction or avoidance of high-lactose foods such as milk, cheese spread, cream and ice cream . However, people with lactose intolerance can often tolerate up to 1 cup of milk, especially when itâs spread throughout the day. This is equivalent to 0.4â0.5 ounces of lactose (

How Do I Know If Im Lactose Intolerant

Have you experienced stomach problems like diarrhea after having milk ...

The best way to determine if youre lactose tolerant or intolerant is to perform an elimination diet. An elimination diet involves eliminating specific foods from your diet for two weeks.

After doing this, youll notice if any particular foods trigger your symptoms. If you dont get diarrhea after removing lactose from your diet, then you know that youre lactose tolerant.

On the other hand, if you do get diarrhea after removing lactase containing foods, then you know that your body cannot break down lactose properly.

Its important to note that you may still experience mild gastrointestinal problems without having lactose intolerance. These include heartburn, indigestion, nausea, and abdominal pain.

These symptoms usually go away within 24 hours. They are caused by the natural digestive processes of the body.

Are there any downsides to drinking lactose-free milk? Lactose intolerance occurs when the body does not produce enough lactase, an enzyme needed to digest lactose milk sugar. Lactose intolerance affects approximately 30% of adults and 90% of infants worldwide. 1 Milk contains lactose, a disaccharide composed of glucose and galactose linked together by a beta-1,4 glycosidic bond. In humans, lactose digestion begins in the mouth and proceeds through the stomach and small intestine. 1:
