Understanding the Causes of Nighttime Coughing

Nighttime coughing can be a frustrating and disruptive experience, often leading to poor sleep quality and daytime fatigue. To effectively address this issue, it’s crucial to understand the underlying causes of nocturnal coughing.

Coughing is the body’s natural defense mechanism to clear the airways of irritants, mucus, or foreign particles. Dr. Liana Casusi, a medical consultant, explains that coughing is “a reflux reaction caused by irritants like dust, smoke, pollution, or mucus, entering the body.”

Wet Cough vs. Dry Cough

While many people differentiate between wet and dry coughs, Dr. Casusi notes that medically speaking, there’s no definitive way to determine the cause of a cough based solely on whether it’s wet or dry. Both types can be caused by various factors, including:

Infections (viral or bacterial)
Structural lung diseases
Airway inflammation from irritants
Asthma and allergies
Certain medications
Heart failure
Gastroesophageal reflux disease (GERD)
Respiratory infections
Lung diseases
Damage to vocal cords
Sleep apnea

Understanding the root cause of your nighttime coughing is essential for finding an effective treatment. Let’s explore some practical strategies to address these underlying issues and reduce nocturnal coughing.

Allergen Avoidance and Environmental Control

For many individuals, allergies and environmental factors play a significant role in triggering nighttime coughs. Implementing strategies to reduce exposure to allergens and irritants can significantly improve sleep quality and reduce coughing episodes.

Identify and Avoid Allergens

Allergens such as dust, pollen, and pet dander can trigger coughing in sensitive individuals. How can you determine if allergies are causing your nighttime cough? Consider consulting with an allergist or trying an at-home allergy test to identify specific triggers. Once identified, take steps to minimize exposure to these allergens.

Create a Dust-Free Environment

Dust is a common irritant that can exacerbate nighttime coughing. To reduce dust in your home:

Vacuum regularly, using a HEPA filter vacuum cleaner
Wash curtains and linens frequently
Replace carpeting and rugs with solid flooring when possible
Opt for blinds instead of curtains to minimize dust accumulation

Optimize Your Bedroom for Allergy Relief

Your bedroom should be a sanctuary for restful sleep. To allergy-proof this crucial space:

Use a HEPA air filter to remove airborne allergens
Invest in allergy covers for pillowcases, duvets, mattresses, and box springs
Wash bedding in hot water weekly
Keep pets out of the bedroom to reduce pet dander exposure

Manage Outdoor Allergens

Pollen and outdoor pollutants can trigger coughing, especially during high pollen count seasons. To minimize exposure:

Keep windows closed during high pollen count days
Check the Air Quality Index at AirNow.gov before spending time outdoors
Shower and change clothes after spending time outside to remove allergens

Addressing Respiratory Conditions and Infections

Respiratory conditions and infections are common causes of nighttime coughing. Properly managing these issues can significantly reduce coughing episodes and improve overall health.

Asthma Management

Asthma is a chronic condition that causes inflammation and narrowing of the airways, often leading to a dry cough. How can you effectively manage asthma-related coughing?

Consult with a healthcare professional to develop an appropriate treatment plan
Use prescribed inhalers as directed
Identify and avoid asthma triggers
Monitor peak flow readings to detect early signs of worsening asthma

Treating Respiratory Infections

Viral and bacterial respiratory infections can cause inflammation and increased mucus production, leading to coughing. To address infection-related coughs:

Rest and stay hydrated
Use over-the-counter cough suppressants or expectorants as recommended by a healthcare provider
Consider using a humidifier to add moisture to the air
Seek medical attention if symptoms persist or worsen

Managing Gastroesophageal Reflux Disease (GERD)

GERD is a common cause of chronic nighttime coughing. When stomach acid flows back into the esophagus, it can irritate the throat and trigger coughing. How can you effectively manage GERD-related coughing?

Lifestyle Modifications

Avoid eating large meals close to bedtime
Identify and avoid foods that trigger reflux
Maintain a healthy weight
Quit smoking
Limit alcohol consumption

Sleep Position Adjustments

Elevating the head of your bed can help prevent stomach acid from flowing back into the esophagus during sleep. Consider these options:

Use wedge pillows to create an incline
Invest in an adjustable bed frame
Raise the head of your bed by 6-8 inches using bed risers

Medical Interventions

In some cases, lifestyle modifications may not be sufficient to manage GERD-related coughing. Consult with a healthcare provider to discuss potential medical interventions, such as:

Over-the-counter antacids
Prescription medications to reduce stomach acid production
Surgical options for severe cases

Improving Indoor Air Quality

The quality of the air you breathe can significantly impact nighttime coughing. By taking steps to improve indoor air quality, you can reduce irritants and allergens that trigger coughing episodes.

Use Air Purifiers

Air purifiers with HEPA filters can effectively remove airborne particles, including dust, pollen, and pet dander. Consider placing air purifiers in bedrooms and frequently used living spaces to improve overall air quality.

Control Humidity Levels

Dry air can irritate the airways and exacerbate coughing. Conversely, excessive humidity can promote the growth of mold and dust mites. What’s the ideal humidity level for reducing nighttime coughing?

Aim for a relative humidity between 30% and 50%
Use a humidifier in dry climates or during winter months
Consider a dehumidifier in humid environments
Regularly clean and maintain humidity-controlling devices to prevent mold growth

Address Indoor Pollutants

Indoor pollutants can contribute to respiratory irritation and coughing. To reduce indoor pollutants:

Avoid using harsh chemical cleaners
Ensure proper ventilation when cooking or using cleaning products
Regularly change air filters in HVAC systems
Consider using indoor plants known for their air-purifying properties

Lifestyle Changes to Reduce Nighttime Coughing

In addition to addressing specific causes of nighttime coughing, certain lifestyle changes can help improve overall respiratory health and reduce coughing episodes.

Quit Smoking

Smoking is a significant risk factor for chronic coughing and various respiratory diseases. How does quitting smoking impact nighttime coughing?

Reduces inflammation in the airways
Improves lung function over time
Decreases the risk of developing chronic respiratory conditions
Enhances the effectiveness of other treatments for coughing

Stay Hydrated

Proper hydration is crucial for maintaining healthy mucus membranes and preventing irritation in the airways. To ensure adequate hydration:

Drink plenty of water throughout the day
Avoid excessive caffeine and alcohol consumption, which can lead to dehydration
Consider drinking warm herbal teas before bed to soothe the throat

Practice Good Sleep Hygiene

Improving overall sleep quality can help reduce nighttime coughing. Implement these sleep hygiene practices:

Maintain a consistent sleep schedule
Create a relaxing bedtime routine
Ensure your bedroom is dark, quiet, and cool
Avoid electronic devices before bedtime
Exercise regularly, but not too close to bedtime

Natural Remedies and Home Treatments

While addressing the underlying causes of nighttime coughing is crucial, certain natural remedies and home treatments can provide relief and support overall respiratory health.

Honey

Honey has been used for centuries as a natural cough suppressant. How does honey help alleviate coughing?

Coats the throat, providing a soothing effect
Possesses antimicrobial properties
May help reduce inflammation in the airways

Try consuming a spoonful of honey before bed or adding it to warm herbal tea.

Steam Inhalation

Inhaling steam can help moisten the airways and loosen mucus, potentially reducing coughing. To practice steam inhalation:

Take a hot shower before bed
Use a facial steamer or bowl of hot water with a towel draped over your head
Add a few drops of essential oils like eucalyptus or peppermint for additional benefits

Elevate Your Head While Sleeping

Sleeping with your head elevated can help reduce postnasal drip and minimize the likelihood of stomach acid reflux, both of which can trigger nighttime coughing. Consider using extra pillows or a wedge pillow to achieve the desired elevation.

Herbal Teas

Certain herbal teas may help soothe the throat and reduce coughing. Some beneficial options include:

Ginger tea
Chamomile tea
Marshmallow root tea
Thyme tea

When to Seek Medical Attention

While many cases of nighttime coughing can be managed with home remedies and lifestyle changes, certain situations warrant medical attention. When should you consult a healthcare professional for your nighttime cough?

Persistent or Worsening Symptoms

If your nighttime coughing persists for several weeks or worsens despite home treatments, it’s advisable to seek medical evaluation. A healthcare provider can help identify underlying causes and recommend appropriate treatments.

Accompanying Symptoms

Certain symptoms accompanying nighttime coughing may indicate a more serious condition. Seek medical attention if you experience:

Shortness of breath or difficulty breathing
Chest pain or tightness
Coughing up blood
Unexplained weight loss
Fever that persists for more than a few days
Severe fatigue or weakness

Risk Factors and Pre-existing Conditions

Individuals with certain risk factors or pre-existing conditions should be particularly vigilant about persistent nighttime coughing. These include:

History of smoking
Chronic respiratory conditions like asthma or COPD
Weakened immune system
Heart disease
Recent exposure to infectious diseases

By understanding the various causes of nighttime coughing and implementing appropriate strategies, you can significantly improve your sleep quality and overall well-being. Remember that persistent or severe symptoms should always be evaluated by a healthcare professional to ensure proper diagnosis and treatment.

How to Stop, Coughing at Night, and More

Coughing is the body’s way of ridding the lungs and airways of invaders, explains Liana Casusi, MD and consultant for Oh So Spotless. “It’s a reflux reaction caused by irritants like dust, smoke, pollution, or mucus, entering the body,” she says.

Wet cough vs. dry cough
Medically speaking, Casusi says that there is no certain way to pinpoint the cause of a cough just by describing it as dry or wet.
“Also known as a productive cough, a wet cough brings out mucus, while a dry cough or nonproductive cough doesn’t,” she says. “Both types of cough can be caused by infections, structural lung disease, or airway inflammation from irritants.”

Coughs can also result from viral or bacterial respiratory infections, such as pneumonia, whooping cough, and croup.

These infections can cause inflammation that increases and thickens the natural mucus in the body. This extra mucus leads to coughing.

Asthma and allergies can also cause coughing due to inflammation, she says.

Other common causes include:

taking certain medications
heart failure
gastroesophageal reflux disease (GERD)
lower or upper respiratory infections
lung disease
damage to vocal cords
sleep apnea

People who smoke have a higher risk of chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema. COPD can cause coughing due to the destruction of lung tissue.

What causes a dry cough at night?

Coughing is a natural mechanism the body uses to remove unwanted substances in the airways. Stopping a cough when it happens will not provide a long-term solution. The main thing is to address the underlying cause.

Below are 20 tips on addressing the underlying cause of coughs.

1. Avoid allergens

Avoiding allergens like dust and pollen can help prevent coughing in people with allergies and sensitivities.

If you’re not sure whether you have an allergy, you might consider consulting with a healthcare professional like an allergist or trying out an at-home allergy test.

2. Rid your home of dust

Keeping your home clear of common allergens like dust, dust mites, and pollen can help lower the risk of coughing.

Tips to help keep irritants at bay include:

vacuuming regularly
washing curtains and linen frequently
swapping carpeting and rugs for solid floors
getting blinds instead of curtains

3. Use air filters to allergy-proof your bedroom

A HEPA air filter can help mite-proof your bedroom.

Other strategies include:

using allergy covers for pillowcases, duvets, mattresses, and box springs to help reduce and prevent dust mites
washing bedding in hot water once per week
keeping pets out of the bedroom

4. Manage asthma

Asthma causes airways to become narrow and inflamed. A dry cough is a common symptom of asthma.

If your cough feels dry and you sometimes have a hard time breathing, consult with a doctor or another healthcare professional. You may need a prescription inhaler to treat asthma.

5. Shut windows

This can help lower the chance of coughing when pollen counts are high or when there’s a lot of dust blowing around.

6. Avoid polluted areas when possible

Exposure to pollution is a common trigger for coughing.

According to the World Bank Group, over 90 percent of the global population is exposed to polluted air every year, so avoiding polluted areas altogether will be tricky.

But if you have a persistent cough, consider checking the Air Quality Index at AirNow.gov to see if you need to take extra care.

How can you improve your air quality at home?

7. Tackle GERD

GERD is a chronic cause of acid reflux and nighttime coughing.

Tips for managing the symptoms of GERD include:

seeing a doctor about medications
following medical advice a healthcare professional provides
keeping a food diary to help identify foods that make symptoms worse

What are some natural remedies for GERD and acid reflux?

8.

Incline your bed

Lying down makes it easier for stomach acid to flow back into your esophagus. So it’s best to wait at least 2.5 hours after eating to lie flat. It may help to raise the head of your bed 6–8 inches.

People with GERD aren’t the only ones who can benefit from sleeping at an incline. Raising the head at night can help manage many types of cough.

It’s easier for irritants to make their way to your throat to trigger coughing when you’re lying down.

Ways of doing this include using wedge pillows or investing in an adjustable mattress or bed.

9. Exterminate cockroaches

The saliva, feces, and body parts of cockroaches can cause coughing and other allergy symptoms.

Prevent cockroaches in your home by:

keeping food containers sealed so they’re unattractive to cockroaches
removing piles of newspapers and magazines that attract dust and give cockroaches places to hide
hiring an exterminator to eliminate an infestation

What is a cockroach allergy?

10.

Use a humidifier

Dry, warm air can dry out your throat and airways and make you more prone to coughing fits. Many people notice their cough worsens around the time they turn their heat on in the winter.

Running a humidifier that produces a cool mist can help keep the air in your bedroom and throat moist.

11. Seek treatment for a sinus infection

Sinus infections can cause postnasal drip, especially when lying down. This can tickle the back of your throat and lead to coughing.

Prescription antibiotics can help clear up a sinus infection and stop both the drip and the cough.

12. Use a neti pot

A neti pot is helpful in washing out the nasal passages, which can help relieve congestion. But be sure to follow the instructions carefully, as incorrect use may increase the risk of infections.

Learn how to use a neti pot safely.

13. Eat honey

“Ingesting 2 to 3 teaspoons of honey before bedtime may help loosen mucus in your throat,” says Casusi.

Another option is to mix 2 teaspoons of honey into a caffeine-free tea, such as herbal tea.

However, never give honey to children younger than 1 year due to the risk of botulism.

Can you use honey for a sore throat?

14. Sip lemon juice

Lemon juice has anti-inflammatory properties. Mixing a little in water might help relieve a cough, as long as you do not have GERD, according to Casusi.

Alternatively, combine several helpful ingredients in a tasty hot drink with lemon juice, ginger, warm water, and honey.

15. Try pineapple

A 2016 study suggests that bromelain, an enzyme found in pineapples, can help thin out mucus and reduce coughing.

Try eating pineapple or drinking pineapple juice.

16. Gargle salt water

Gargling with a saltwater solution can help clear out airway congestion and help stop coughs due to asthma, allergies, and infections.

To make a saltwater gargle, mix a half teaspoon of salt into 8 ounces of warm water.

17. Take decongestants for a cold

The common cold can cause coughing.

There’s no cure for a cold, but rest and plenty of fluids can help you feel better.

If your cough is severe and you are an adult or a child older than 6 years, decongestant sprays and cough medications may help.

What are some cold and flu home remedies?

18. Try an over-the-counter medication

Over-the-counter (OTC) cough remedies can deal with coughing in several ways. Cough suppressants lessen the urge to cough, while expectorants thin mucus and make it easier to cough up.

Ask a pharmacist to help you choose a medication that suits your cough.

Learn about cough suppressants and other medications for coughs and colds.

19. Get your shots

Vaccines to prevent flu and COVID-19 can help prevent these viral infections, both of which can cause coughing.

20. Avoid tobacco smoke

A chronic cough is a common side effect of long-term smoking or exposure to secondhand smoke.

Quitting smoking or asking smokers to smoke outside can improve your cough and your overall health.

Talk with a healthcare professional if you smoke and need help to quit.

Most coughing does ease up in time, but severe and persistent nighttime coughing can be a sign of a serious condition, such as:

heart failure
bronchitis
pneumonia
COPD
lung cancer

A severe or persistent cough needs medical attention.

You should also get medical help if you have a cough and:

a fever of 100.4°F (38°C) or above
shortness of breath
choking
swelling in your legs, ankles, or abdomen
wheezing
chest pain
increasing amounts of phlegm
blood in phlegm or coughing up blood

Other tips about getting medical help include:

seeing a doctor if you have a persistent cough that does not go away or gets worse
seeking help if a cough disrupts your sleep, daily life, and overall well-being
following any treatment plan as the doctor recommends
completing any course of antibiotics for a bacterial infection, even if your symptoms improve
going back to the doctor if any medications seem to make the cough worse

Many of the same things that cause a daytime cough can also cause a nighttime cough.

But a cough may worsen at night due to your sleeping position, the quality of bedroom air, and exposure to lint, dust, pollen, and mites from bedding.

Whatever the cause, various home remedies and lifestyle measures can help relieve a nighttime cough, such as:

using pillows to raise your head
inclining your mattress
investing in a humidifier
washing bedding and vacuuming floors frequently
keeping windows shut at times of high pollen or air pollution

If they don’t help, you may need to take OTC medication or seek medical help for prescription cough medication or for an underlying condition.

We do the research so you can find trusted products for your health and wellness.

At-home test kits

Most at-home allergy tests use a small blood sample. When you order a kit, you’ll receive everything you need to take the sample.

After pricking your finger with the included lancet, you’ll squeeze a few drops of blood onto the collection card provided before mailing it back to the test company. Kits include detailed directions and all the materials you need.

After you send in your sample or have your blood drawn, it will be tested at a Clinical Laboratory Improvement Amendments (CLIA)-certified lab. This certification indicates that the lab has met standards for state and federal certification and is regularly inspected to ensure compliance. Tests are also reviewed and approved by board certified physicians.

Companies that provide these at-home allergy tests should also be compliant with Health Insurance Portability and Accountability Act (HIPAA), so you can be sure your test results are securely stored.

An allergist’s test

When you visit an allergist to diagnose an allergy, you’ll go over your medical history and any symptoms you’ve been experiencing.

You can expect to answer questions about your environment, lifestyle, and any history of allergies both personally or in your family.

Though a detailed discussion of allergic reactions with an allergist is the first step in identifying food allergies, skin and blood testing can also be helpful to clarify and confirm suspected food allergies. These tests offer a more personalized, in-depth view than at-home tests.

Allergists use several different types of analyses. Typically, these include skin prick testing or an IgE blood test.

Skin prick tests can identify various potential allergens, including airborne, contact, and food-based. There are three kinds:

scratch
intradermal
patch

An allergist may also test you for any type of allergy by exposing you to a small amount of a particular allergen and recording your body’s reaction.

Blood tests are performed in the event you may have a serious allergic reaction to a skin test, or if you’re unable to perform a skin test. A blood sample is taken and tested in a lab for the presence of antibodies.

Skin testing is typically used to clarify which environmental allergens (pollens, dust mite, animals, or molds) may be triggering your symptoms. Blood testing for immunoglobulin E (IgE) antibodies can also similarly identify which environmental allergens are a problem for you.

IgE is usually present in small amounts in the blood, but elevated levels can be a sign that the body is overreacting to specific allergens.

In both cases, your allergist will be able to explain your results and next steps.

One thing to keep in mind: Before going into your appointment, you may also be asked to stop certain medications, including antihistamines, some heartburn medications, and others, which could interfere with your test results.

The type of allergy symptoms you are experiencing — and the type of allergens you and your doctor are concerned about — will help determine which type of tests are appropriate for you. Allergens can be classified into three groups:

Inhaled allergens come into the body via the lungs or the membranes in the throat or nostrils. Pollen is a good example.
Ingested allergens are those found in foods such as seafood, soy, or peanuts.
Contact allergens produce a reaction through direct contact with the skin. For example, poison ivy can trigger an allergic reaction in the form of an itchy rash. Similarly, some products like creams, soaps, or even jewelry could also trigger this reaction, even if you’ve used a product for years.

More about ingested allergens

If you’re concerned that food could be triggering your symptoms, your doctor may order a skin test and blood test for IgE antibodies. These tests can help determine what kinds of allergies are causing severe, immediate reactions, like hives, vomiting, or breathing problems.

However, if you experience food-related allergy symptoms that are not this severe or immediate, these tests are unlikely to pick up on the foods that are causing your symptoms. These tests also tend to be overly sensitive to food allergies, meaning that the tests may pick up more food allergens than are relevant to you. That’s why it’s important to work with a doctor to determine which foods should be tested, and whether testing will be helpful for you.

There’s a difference between being allergic to a food and being intolerant to it. True food allergies trigger the immune system, which causes your body to react.

With a food intolerance, which is more common than a food allergy, your body’s digestive system is triggered. Food intolerances are caused by the body’s inability to properly process a food.

While food intolerances aren’t typically dangerous, certain food allergic reactions may require immediate medical treatment.

The body will react differently to a food allergy than it will to a food intolerance. Symptoms of a food allergy can include:

hives
swelling
itching
dizziness
vomiting
rash
difficulty breathing
anaphylaxis

Allergy tests (skin tests and IgE blood tests) can often help clarify which foods may be causing these types of symptoms. There are some types of food allergies (where the immune system triggers the food reaction) that manifest with more nonspecific types of symptoms, such as delayed vomiting, difficulty swallowing, or stomach aches.

Symptoms of a food intolerance can include:

gas
bloating
cramping
diarrhea
constipation
nausea

For these types of symptoms, skin tests and IgE blood tests may not help figure out what’s causing your symptoms. There are some tests that may help clarify food triggers, but these are specific to the type of food intolerance suspected.

In other words, doing a panel of food tests is unlikely to help determine the food triggers. For example, breath tests can be useful for suspected lactose intolerance. An allergist can help you figure out which tests would be most beneficial for you.

Finally, there are certain types of food allergies and intolerances where the diagnosis is based on symptoms and dietary history alone. In these cases, the diagnosis is only confirmed by avoiding the food for short periods (1-2 weeks), followed by adding the food back to diet. Which, if any, trial food eliminations may be necessary should be discussed with a physician.

Common culprits

The most common food allergies include:

milk
eggs
fish
shellfish
peanuts
tree nuts
wheat
soybeans
sesame

Common food intolerances include:

dairy
gluten
caffeine

It’s important to understand that none of the food intolerances listed above can be diagnosed with an at-home intolerance test. If you suspect that dairy, gluten, or caffeine may be triggering symptoms, an at-home test won’t be able to diagnose it. Even worse, you may end up with misleading results.

Some at-home allergy tests claim to be able to diagnose food sensitivities through the food immunoglobulin G (IgG) test. This test shows results for typically 90 to 100 foods that you may be intolerant to, and recommend removing these foods from your diet to improve multiple symptoms. The American Academy of Allergy, Asthma, & Immunology (AAAI) states that these tests have never been scientifically proven to be able to accomplish what it reports to do.

IgE panel testing for foods is controversial. It’s rarely recommended by allergy societies, especially when done without a proper and thorough medical history of the patient. In those cases, it’s common that 50% to 90% of IgE results without a proper reading can be incorrectly identified.

There are advantages and drawbacks to completing an IgE allergy blood test at home.

Pros

convenient

Cons

IgE testing to foods may diagnose food allergies or intolerances you don’t have because of the high risk of false positives
both IgE and IgG testing may miss relevant allergies and intolerances
food IgE and IgG tests can’t diagnose common intolerances like lactose or FODMAP, nor can they detect potentially serious food-induced conditions like celiac disease
high price point
some tests still involve a visit to a lab
tests are not regulated
don’t provide treatment plans for potential intolerances or allergies

Was this helpful?

An at-home allergy test may be worth the money if you’re testing for environmental allergens. In that case, “at-home IgE testing can be helpful in identifying relevant allergens,” said Healthline medical reviewer Elizabeth Feuille, MD.

But when it comes to suspected food allergies, the answer is short and sweet: No. That’s because:

Indiscriminate food allergy testing using panel testing is rarely useful

“The testing is not a measure of how allergic you are to a food,” said Feuille. “It is simply a measure of how much allergy antibody you produce to a food.”

Since it’s common for people to make allergy antibodies to a food without actually having a true allergy, you may end up with results that show you’re allergic when you actually tolerate them without symptoms or consequences.

IgE-mediated food allergy tests only evaluate IgE-mediated allergies

This kind of allergy is associated with symptoms like hives, vomiting, and breathing problems. “If you suspect you may have any other type of food allergy or food intolerance (for example, celiac disease or lactose intolerance, among many other types of food-induced syndromes), this testing will not identify foods that are causing your symptoms,” said Feuille

Food allergy panel testing can actually cause significant harm

Parents may mistakenly assume that they need to eliminate culprit foods from a child’s diet based on indiscriminate food panel testing.

“In some cases, this can result in significant dietary limitations and malnutrition,” said Feuille. “At-home food panels should never be used to guide an elimination diet for a child.”

The same is true for adults, who can also develop nutrition issues from excessive dietary limitations. But the risk is greater for children, who are vulnerable to malnutrition.

Something else to keep in mind: Studies have shown that avoiding certain foods, like peanuts or eggs, in children who make allergy antibodies to these foods can actually significantly increase the risk of developing a true allergy to these foods. In other words, the effort of eliminating a suspected allergen actually creates the allergy.

A severe allergic reaction may cause these symptoms:

abdominal cramping or pain
diarrhea
nausea or vomiting
pain or tightness in the chest
difficulty swallowing
difficulty breathing
wheezing
fear or anxiety
heart palpitations
flushing of the face
swelling of the face, eyes, or tongue
dizziness or vertigo
weakness
unconsciousness

If you experience any of these symptoms, see a doctor right away.

If your symptoms are mild but persistent, you may want to visit a specialist. For example, a dermatologist may be the best option if your reaction is affecting your skin.

An allergist is a good choice if your symptoms include nasal congestion or ongoing sinus infections, or if you notice allergy symptoms during certain times of the year. Allergists also manage skin conditions like rashes and hives that occur due to allergic reactions.

If you aren’t sure where to begin, visit your primary care physician for an initial diagnosis.

Are at-home allergy tests accurate?

The analysis you’ll get from an at-home allergy test won’t be as thorough or complete as what you would get from a doctor or allergist.

While at-home allergy tests may offer some insight into environmental allergens, they’re not a good option for suspected food allergies. That’s because indiscriminate food allergy testing rarely provides useful information.

What’s more, IgE-mediated food allergy tests only test for IgE-mediated allergies, so they won’t identify other types of food allergies or intolerances, such as celiac disease or lactose intolerance.

Finally, keep in mind that results from both IgE and IgG testing can be inaccurate or misleading. Your best option for a suspected allergy is to speak with a qualified healthcare professional.

Does insurance cover at-home allergy tests?

In most cases, insurance will not cover the cost of at-home allergy tests. At this time, that’s the case for the at-home allergy test we recommend.

What is the most accurate way to test for allergies?

A visit to your doctor or allergist is the most accurate way to test for allergies. That’s because your healthcare practitioner will offer a more thorough approach to testing, including asking about your symptoms and performing a physical exam. Based on these assessments, your doctor can decide which test is appropriate. That could be a skin prick test or blood test.

Like the at-home allergy test, a doctor’s blood test will look for the presence of IgE antibodies.

A skin test can be performed with a referral to an allergist. This test is performed by pricking or scratching the skin with small needles to document your skin’s reaction to potential allergens.

Can you test negative for allergies and still have them?

Yes. Since many tests look for the most common kinds of allergens, it’s possible to have an allergy to something that doesn’t show up on a blood test.

Keep in mind that IgE testing can only identify IgE-mediated allergies, and there are a number of food-induced conditions that fall outside that scope. At this time, IgE tests do not diagnose or exclude any condition and are really only a measure of exposure to a specific food.

What does a positive allergy test look like?

It depends on the test. At-home allergy test results are designed to be easy to interpret and typically indicate your reactivity to various allergens, using a color or number scale.

It’s a good idea to speak with an allergist about your results, especially if you have questions about next steps.

Many healthcare professionals consider at-home allergy tests unreliable. The worst-case scenario is interpreting the results on your own and then taking steps to address an allergy that may not be warranted.

In the best case, an at-home allergy test that’s specific to environmental allergies could provide information that may be useful in highlighting how your body reacts to certain allergens. But at-home allergy tests aren’t a good choice if you suspect food allergies or intolerances.

It’s always best to consult a healthcare professional about allergies, and that’s still true if you decide that an at-home allergy test is your best option.

Ask a doctor for advice on any tests you may be considering, and discuss results with a board certified allergist.
