If Lactose Intolerant How Do You Know You Are

Am I Lactose Intolerant?

Learn how to tell if you have this common digestive problem.

Lactose intolerance, the inability to intermission down lactose—the natural sugars found in milk and milk products—is extremely common. Approximately 30 one thousand thousand American adults have some degree of lactose intolerance by historic period 20, according to the U.S. National Library of Medicine.

Humans cannot digest lactose without the assistance of an enzyme chosen lactase, says Richard Auld Jr., M.D., a gastroenterologist at Sutter Pacific Medical Foundation in Santa Rosa. If your digestive system produces and maintains sufficient levels of lactase, which splits lactose into the much-more than-absorbable sugars glucose and galactose, yous should be able to tolerate milk products.

But most people across the world, besides every bit a big portion of the U.S. population, are deficient in lactase. Genetics play a huge function in determining whose bodies exercise and do not produce plenty of this enzyme. Lactase deficiency is far more prevalent among sure ethnic groups, peculiarly people of Native American, African-American, Asian, Mediterranean and Jewish descent.

Genetics aside, anyone's torso can lose the ability to maintain adequate lactase levels as they historic period. It's too common to cease producing the enzyme temporarily following a bout of infectious gastroenteritis. "And if you accept a lot of NSAID painkillers like ibuprofen or aspirin, or if you hurt your small bowel in any way, your lactase levels will probable be lower," Dr. Auld says.

Symptoms of Lactose Intolerance

If your trunk can't digest lactose-containing dairy products, you lot can experience unpleasant side effects, including abdominal hurting, bloating, cramps, flatulence, nausea and diarrhea. These symptoms normally commencement inside 30 minutes to two hours afterwards consuming lactose. If you lot take down a large corporeality of dairy at one time, your woes will probably be much worse.

But ironically, if your dairy binge consists of a lot of fatty—such equally a bean-and-cheese burrito smothered in guacamole—your symptoms may not be as bad. "If you commonly follow a dairy-free diet but cheat with a high-fat meal, information technology can be healing," Dr. Auld says. "Fat leaves the stomach twice as slowly as the sugars, and then you're not putting a bunch of lactose in the small bowel at one time."

How to Know You're Truly Intolerant

First off, know that lactose intolerance is not the same matter as a milk allergy, which Dr. Auld says is quite rare, especially among adults. More often, it's babies and modest children who are allergic, only fifty-fifty they oftentimes outgrow milk allergies over fourth dimension. The symptoms of a milk allergy are also different from those of lactose intolerance. Rather than bloating or tum upset, "these kids get really sick," says Dr. Auld. Milk kicks their allowed arrangement into overdrive, and they may develop a rash, hives, swelling or, in severe cases, struggle to breathe.

If your symptoms (general bloating, diarrhea) indicate intolerance, there's a simple and fairly reliable way to determine whether you're lactose intolerant. Just eliminate milk products from your nutrition for two weeks to see if your symptoms subside. Download a 3-day, dairy-free meal plan to go started.

Only if yous're still not sure—or if you want extra balls earlier banning your beloved lattes—ask your doctor to perform a diagnostic exam to prove you're lactose intolerance. The most common is the hydrogen breath exam, which measures the amount of this gas in your breath. Normally, there is very piddling. "But if you give someone who'south lactose intolerant a bunch of lactose, it will become broken down by bacterial fermentation in your colon, which will generate hydrogen," Dr. Auld says. "This is why you get gas and diarrhea." But in the process, you lot'll also exhale enough hydrogen to brand it clear that yous're lactose intolerant.

Your doctor can also recommend a lactose tolerance blood test. Since the body creates glucose when it breaks down lactose, this test looks for changes in glucose levels in your claret before and after y'all've consumed lactose. If the amount of glucose doesn't ascent to a certain level afterwards drinking a lactose solution, that signals an intolerance. Merely before getting either of these tests, Dr. Auld strongly advises trying the dairy-elimination route considering it will likely requite you the answers you demand.

Treating Lactose Intolerance

In that location is no known method of preventing or curing lactose intolerance. The severity of your lactase deficiency will decide which products or strategies work best for your trunk. You may be able to consume small-scale amounts of milk or tolerate lower-lactose milk products, such as hard cheeses and yogurt with live cultures.

Or, you lot may need to avoid dairy birthday and choose lactose-gratuitous milk products, such every bit Lactaid, or other dairy-like products made from soy, almonds, rice or coconuts. "Another thing I've seen piece of work actually well is over-the-counter lactase pills," Dr. Auld says. Too bachelor as liquid drops, these may brand lactose-containing foods more tolerable.

Keep in listen, milk products hide in a surprising number of food products. Packaged snack foods, chocolates, cakes, creamy sauces, salad dressings, salami, and boxed soups and potatoes often incorporate dairy. Make certain to written report any packaged food'due south ingredient list for lactose code words, including milk, lactose, whey, curds, milk past-products, dry out milk solids and nonfat dry out milk pulverisation.

Getting Plenty Nutrients

Milk and milk products are a major source of calcium, crucial for bone wellness and building potent teeth. So when you lot limit or completely ditch dairy products, you run the take chances of inadequate calcium intake. Over fourth dimension, this can contribute to osteoporosis—weak, brittle bones that fracture easily.

If yous're dairy-free, Dr. Auld advises loading up on calcium-rich foods, such as leafy greens, broccoli, okra, oranges, almonds, canned salmon, sardines, soy products and legumes. However it notwithstanding tin can be tough to go plenty calcium from these foods alone, he says, so consider taking calcium supplements—peculiarly if you're a adult female who is meaning or nursing. Calcium requirements vary by age, gender and other factors, so talk with your doctor nigh how much of the mineral y'all should shoot for each 24-hour interval.

And don't forget about vitamin D. "If you follow a low- or no-dairy diet, y'all're going to take a problem with depression vitamin D levels," Dr. Auld says. "Very few foods contain sufficient vitamin D; you lot'd need to eat a whole lot of leafy greens."

But even if you do dairy, the best source of vitamin D is sunlight exposure. And between working indoors and slathering on sunscreen when enjoying the outdoors, throngs of Americans lack this essential nutrient. "In San Francisco, vitamin D deficiency is the rule rather than exception," Dr. Auld says. So just every bit with calcium, if you're lactose intolerant, definitely consider vitamin D supplements.
