How long do food sensitivity symptoms last

By adulthood, up to 70 percent of people don’t produce enough lactase to properly digest the lactose in milk.

But how long do lactose intolerance symptoms last?

Lactose intolerance symptoms like pain, bloating, nausea, diarrhea, and gas usually last around 30 minutes to 2 hours after eating dairy.

Once the dairy passes through your system, your symptoms should stop.

Here’s what to expect.

What are the symptoms of lactose intolerance?

Lactose intolerance refers to your body’s inability to break down a natural sugar called lactose, found in your fave dairy products. When your small intestine stops making enough of the enzyme lactase, which breaks down lactose, you’ve got a prob on your hands — and in your gut.

When this happens, the undigested lactose travels to your large intestine, where it can cause the following symptoms:

  • bloating
  • gas
  • nausea
  • vomiting
  • diarrhea
  • stomach cramps
  • feeling sick

Lactose intolerance is especially common in adults with Asian, African, and Hispanic ancestry. But even though you’re in good company, that doesn’t make your digestive probs any easier to stomach!

If you took an ill-advised ride on the dairy train, buckle up. Here’s what to know about the gut-churning road ahead.

Moo, hiss: How long do lactose intolerance symptoms last, really?

Most of the time, symptoms of lactose intolerance can happen about 30 minutes to 2 hours after eating dairy and will go away when it completely passes through your system.

Though lactose intolerance can be stressful, the experts from Harvard Health Publishing say it’s not a dangerous condition. But when you feel like a dairy demon crawled in your gut, understandably, it might feel otherwise.

The severity of your symptoms might vary based on how much dairy you downed and the amount of lactase your bod produces.Hold tight, though: According to a research review, unpleasant effects typically fizzle out within 48 hours max unless you keep eating lactose-containing products.

In the meantime, you might experience any of the following symptoms:

  • Bloating. Nothing like eating a few slices of extra cheesy pizza… until the bloat comes on, that is. Bloating happens due to trapped water and gas in your intestines. You’ll usually feel it around your belly button.
  • Nausea. If you have lactose intolerance, nausea often happens within 2 hours of nomming on some yogurt, cheese, or ice cream.
  • Diarrhea. Like the “Bob’s Burgers” song goes, “some people think it’s funny, but it’s really wet and runny: diarrhea.” Yep, pretty much. Diarrhea happens when undigested lactose ferments (yeah, like how pickles ferment) in your gut, causing increased water retention.
  • Pain. Lactose intolerance is seriously a pain in the butt… and gut. When trapped gas pushes against your intestinal walls, it can lead to aches and pains.
  • Gas. You don’t want to be on a crowded subway when lactose intolerance strikes. Fermenting lactose often causes a buildup of hydrogen, methane and carbon dioxide in your gut: One chemical reaction no one wants to witness.

Hold up: Lactose intolerance symptoms for days?

That’s 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.

Hmm, how long do other food intolerance symptoms last?

Your tummy probs just might point to something other than lactose intolerance. Food allergies, food intolerances, and other digestive conditions can likewise wreak havoc on your digestive system.

For instance, according to the Office of Women’s Health, lactose intolerance causes similar symptoms to irritable bowel syndrome (IBS) including stomach pain, cramps and diarrhea. However, lots of foods can trigger IBS, while dairy is the sole culprit of lactose intolerance.

According to the FDA, lactose intolerance is also not to be confused with the (much less common) milk allergy, which causes more serious symptoms like:

  • shortness of breath
  • throat swelling
  • mouth tingling

So, what’s the difference? Basically, a food allergy refers to an immune system reaction that can cause serious symptoms throughout your body like, hives, itching, facial and throat swelling (think peanuts and shellfish). It can even be life threatening.

Meanwhile, food intolerances, such as lactose intolerance, stem from your body’s inability to break down a particular food (see: gluten) and usually only impact your digestive system. Here’s how long you can expect symptoms from a few of the most common ones to last:

  • IBS. IBS symptoms can last for days or even months.
  • Dairy intolerance. Dairy intolerance symptoms usually happen within 2 hours of consumption and can last for up to 72 hours.
  • Gluten intolerance. Gluten intolerance typically flares up shortly after eating gluten (like, a matter of minutes) and can last for days.
  • Celiac disease. Celiac disease is a more serious form of gluten intolerance. When people with this autoimmune condition eat gluten, it causes damage to your small intestine. Symptoms usually emerge within minutes to up to 2 hours of consumption. They should subside within a few days.
  • Alcohol intolerance. Those with alcohol intolerance typically notice probs within 20 minutes of having a cocktail, beer or glass of wine. Symptoms will last until the alcohol passes through your system, or around 12 to 48 hours after drinking.

Wait! Will I be lactose intolerant forever, forever-ever?

Once lactose intolerant, always lactose intolerant. That’s because the condition is caused by a deficiency of the enzyme lactase, and at least right now, doctors and scientists don’t know a way to increase your body’s production of this enzyme.

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

So, unfortunately, it might be time to kiss your lasagna and dairy ice cream goodbye for good. On the bright side, we’ve fully entered the era of the milk alternatives, so there are tons of options to choose from. (Pro tip: if you haven’t tried oat milk, you gotta.)

When to call a doc about lactose intolerance (adsbygoogle = window.adsbygoogle || []).push({});

Lactose intolerance sucks, truly. I mean, who wants to forego cream cheese bagels? But thankfully, it’s not usually a serious condition. Most of the time, you can deal with the concern on your own by cutting out dairy. (OK and I guess there are some other legit bagel toppings out there.)

But if you’re not sure lactose is the culprit, then you may want to chat with a doctor to rule out other digestive conditions. A healthcare provider can check your diagnosis in one of three ways:

Lactose tolerance test

During a lactose tolerance test, your doc will take a blood sample and check your fasting glucose levels. Then, you’ll drink a lactose liquid. Over the next few hours, the doc will compare your blood glucose levels to your baseline.

If your glucose levels didn’t climb, it means your bod can’t break down the lactose into individual sugars. In that case: Yep, you’re lactose intolerant.

Hydrogen breath test

During a hydrogen breath test, you’ll down some liquid with a high concentration of lactose. The doc will then measure the level of hydrogen in your breath.

If you’re lactose intolerant, the fermented lactose will heighten hydrogen levels in your breath, but it can also indicate other conditions as well. Your medical provider can help you interpret the results based on your symptoms and experience.

Stool acidity test

The stool acidity test is usually reserved for children who can’t be tested with other methods. The doctor will examine a stool sample to test for undigested lactose, which appears in the form of lactic acid.

How to deal: Living with lactose intolerance

A lactose-limited life isn’t easy, but it’s definitely better than spending every other day stuck on the toilet or wanting to vom. Live your best (low dairy) life by trying the following tips:

How long does it take for a food sensitivity to go away?

Try cutting out the suspected food from your diet for 2 to 6 weeks and see if your symptoms improve. Reintroduce the food to see if symptoms return. You may find you can tolerate a certain level and you only get symptoms if you have more than this amount.

What are 3 signs of food sensitivity?

The most common food allergy signs and symptoms include:.
Tingling or itching in the mouth..
Hives, itching or eczema..
Swelling of the lips, face, tongue and throat or other parts of the body..
Wheezing, nasal congestion or trouble breathing..
Abdominal pain, diarrhea, nausea or vomiting..
Dizziness, lightheadedness or fainting..

Can food allergy symptoms last for days?

Allergic reactions to foods may occur within a few minutes after eating the food, but rarely symptoms may also develop after hours, making the relationship with ingestion of food less clear. Symptoms generally disappear within hours but can last for days.

Do food sensitivities go away?

Food intolerances tend to be lifelong. Most people can manage symptoms if they reduce or cut out foods that cause digestive problems. Food intolerance may be an inconvenience (and the symptoms unpleasant), but it isn't a life-threatening problem like a food allergy.
