How to Get Rid of a Stuffy Nose, Depending on What’s Causing It

If you really want to get rid of a stuffy nose fast, you need to know what’s causing it. Here, find out what’s causing you to be so stuffed up, and how to get rid of the congestion.

Some 50 million people in the US suffer from allergies, says the American College of Allergy, Asthma, & Immunology (ACAAI). Common allergens include pollen, pets, dust, mold, and grass. In addition to sneezing and itchy, watery eyes, the classic symptom of allergies is a stopped-up nose. How to get rid of a blocked nose? The simplest strategy is avoidance. If you know you have an allergy, stay away from your triggers or protect yourself by wearing a mask and taking showers after being outdoors, especially on dry, windy days.

Over-the-counter antihistamines, which work by blocking an immune system chemical called histamine that’s involved in allergic reactions, can help unstuff your nose, per the US National Library of Medicine (NLM). So can saline nasal rinses, says NLM. Make sure you use purified (aka distilled), filtered, or boiled water, or consider picking up an OTC saline spray or wash.

If nothing clears your stuffed-up, allergic nose, consider allergy shots. “It comes as close [as we have] to a cure for allergies,” Christopher Chang, MD, an ear, nose, and throat (ENT) specialist in Warrenton, Virginia, tells Health.

Colds and the flu

A dramatically stuffed nose is a hallmark symptom of both colds and the flu, which are caused by viruses. There’s no cure for either and they usually go away on their own. However, if you don’t take care, you could get a secondary infection from bacteria that grow in your “stagnant mucus,” Lisa Liberatore, MD, an ENT in New York City, tells Health, which could be even more serious.

An array of over-the-counter cold and flu medicines containing decongestants (which shrink the inflamed blood vessels blocking your nose) and/or antihistamines can help clear congestion, says the American Academy of Family Physicians. Nasal rinses can, too, by washing viruses and bacteria away, explains Denver-based National Jewish Health.

But other self-care is also key. “I emphasize the importance of hydration, staying away from alcohol, and getting plenty of sleep because lack of sleep [hampers] the immune system,” says Dr. Liberatore. “If there’s any time you want to prioritize sleep, it would be when you’re sick.”

Acute sinusitis


Your sinuses are the cavities in your skull that help drain mucus out of your system. If the sinuses become inflamed (often due to an infection), you could end up with nasal congestion, says ACAAI.

Bacteria, viruses, and allergens (such as mold) can cause sinusitis, adds ACAAI. The condition can be acute, meaning it lasts only a few days to a couple of weeks, or chronic, when, per Mayo Clinic, it lingers for 12 weeks or more.

If your sinus infection is from bacteria, antibiotics may help, but the best thing you can do for sinusitis caused by a virus is control the symptoms. Stay away from antihistamines, which dry things out, says Dr. Liberatore, in favor of OTC decongestants, which help drain the sinuses instead. (Caution: decongestants can raise blood pressure, so if you have hypertension, talk to your doctor before taking them.) Nasal sprays containing steroids may also help.

Once the congestion and stuffy nose of acute sinusitis have eased, flush away the mucus with a saline rinse, says Dr. Liberatore.

Chronic sinusitis


When inflamed or infected sinuses don’t get better, you might have chronic sinusitis, which is when the swelling of the sinuses persists for more than three months, says NLM.

If decongestants, nasal sprays, and self-care routines like rinsing don’t help, you may need to see a specialist who can recommend other medications or may even suggest surgery. Traditional sinus surgery involves taking out infected bone, tissue, or polyps to open up the passages, making more room for mucus to drain, per the Cleveland Clinic.

Sinusplasty is another option, says Mount Sinai Health System. The doctor inserts a balloon into the sinuses, inflates it to stretch the area, then removes it. Or, you might benefit from a stent-like device, which keeps the drainage holes in the sinuses open and releases medicine to help prevent the opening from scarring over.

Deviated septum


Sometimes a stuffy nose is caused not by outside invaders but by internal structural problems. The most common is a deviated septum, says the American Academy of Otolaryngology-Head and Neck Surgery. That’s when the cartilage-and-bone divider between the nostrils warps out of shape, usually because of an injury such as a broken nose.

One sign of a deviated septum is only being able to breathe out of one side of your nose. “If [the septum] is bent over to one side, it’s only going to cause problems on that one side,” explains Dr. Chang.

Treatment depends on how badly your breathing is affected. If you can still breathe fairly easily, allergy medications to open up the breathing passages might help, but many people need surgery to widen the passages permanently. Procedures to repair a deviated septum are usually quick (30 to 90 minutes) and improve breathing in 90% of patients, says the Cleveland Clinic.



Certain things you expect with pregnancy: a protruding belly, morning sickness, swollen feet. So a stuffy nose when you’re expecting may take you by surprise. It’s called rhinitis of pregnancy and is due to more blood flowing into the soft tissue of the nose, says Dr. Liberatore. Some women escape the problem, but if you do develop a blocked nose, it can last the entire nine months.

The condition isn’t life-threatening, but treating it with medicines can be risky. Instead, most women have to rely on saline rinses. “It may seem low-tech, but it actually really does help move any stagnant mucus out of your nose,” says Dr. Liberatore. That will help prevent a secondary bacterial infection and can relieve the pressure you might be feeling.

If you have a deviated septum, talk to your doctor about correcting it before getting pregnant, as surgery isn’t an option once you’re expecting, she says.

Enlarged adenoids


Enlarged adenoids are a common problem in children that can make it hard to breathe, according to the NLM. The adenoids are folds of tissue at the back of the throat, which, in a child under 5, help stave off infections. After age 5, the adenoids shrink and aren’t as involved in fighting off bugs. Sometimes, though, infections cause swelling in the adenoids. This can leave your child with not just a congested nose but blocked ears and chapped lips from breathing through his or her mouth.

Nasal spray or antibiotics may make the symptoms manageable, says NLM. Some children will have to have their adenoids removed though, especially if they have trouble sleeping.

Nasal polyps


Nasal polyps are little bits of tissue that grow in your nose. Chronic inflammation causes the lining of the nose to blister. While scientists don’t know exactly why this happens, they’re associated with asthma, recurrent infections, and allergies, according to the Mayo Clinic.

Polyps usually don’t hurt, but if they become big enough, they can block the sinuses and nasal passages, giving you a stuffy nose, per Mayo Clinic. They can also impair your sense of smell and taste. If you have cystic fibrosis or asthma, you may be more susceptible to developing nasal polyps.

For about 10% to 20% of people with these growths, oral or nasal steroids are enough to shrink the polyps and prevent them from coming back, says Dr. Chang. Everyone else is a candidate for surgery, but even that may not be enough. “Once you get them, they tend to come back,” he says. Some people may need more than one surgery; others may need to stay on medication for years. If nasal polyps do return, you’ll need to be diligent about preventing the triggers of the polyps, like infections, he says.

Narrow nasal passages


Some people happen to be born with narrow nasal passages. If you’re one of them, you may also suffer from a perpetually stuffed nose. This can be caused by overly large turbinates, says the American Academy of Otolaryngology-Head and Neck Surgery. Turbinates are tiny humidifiers in the nose that make sure air you inhale is moist when it hits your lungs.

If you have narrow nasal passages, you might find breathing to be difficult just some of the time. “If [people with narrow nasal passages] breathe slowly through their nose then they’re just fine,” says Dr. Chang. “But if they try to breathe quickly, the airway collapses, and they end up having to mouth breathe.” Surgery to reduce the size of the turbinates may be necessary, although some allergy meds and steroid sprays may also help.

Chemical irritants


Certain compounds might irritate your nose and lead to congestion. Fragrances are a common culprit, says ACAAI.

Not only can fragrances stuff up your nose, they can also cut off your sense of smell, which can in turn stuff up your nose even more. “You’re using more [product] because you’re not appreciating the smell, then all those chemicals are irritating the nasal cavities,” explains Dr. Liberatore.

If you think products could be contributing to your stuffy nose, look for fragrance-free options.



Stress and other strong emotions can cause changes in hormone levels that make the blood vessels in the nose get bigger, constricting your nose and making it harder to breathe. This is called nonallergic rhinopathy, says the Mayo Clinic, and is similar to what happens to some pregnant women who get stuffed up. The best course of action is to identify the source of your stress and either eliminate it or find a healthy way to deal with it, like playing with your dog, getting some exercise, or taking a few minutes to meditate.

Other things that irritate the nose can also cause nonallergic rhinopathy, like dry air, air pollution, and spicy foods, per Mayo Clinic. Talk to your doctor about finding your trigger and the best course of treatment.

Runny nose due to COVID-19

You might think of fever, cough, or shortness of breath as classic signs of COVID-19. But nasal congestion or runny nose are possible symptoms too, says the US Centers for Disease Control and Prevention (CDC).

If you think your nasal symptoms are COVID-related, don’t just ignore the problem. Anyone who has symptoms should get tested, says the CDC.

Even if your illness is mild, you should stay home, except to seek medical care. CDC recommends resting, hydrating, and taking acetaminophen to help you feel better. You’ll also want to monitor your symptoms and contact your health care provider about next steps. Anyone who develops breathing difficulties, chest pain or pressure, or other concerning symptoms should seek emergency medical care.

When to call your doctor about a stuffy nose


Treatments for a stuffy nose run the gamut, and most doctors start with the least invasive option before working their way up to more extensive measures.

That means doctors usually start with a nasal saline rinse or some nasal steroid sprays like Flonase or Nasonex. You can also try over-the-counter antihistamines and keep that routine going for about four weeks.

If your nasal congestion persists, or if your stuffy nose comes with thick, discolored mucus, an overall feeling of being unwell, fever, dental pain, or severe headache, it’s time to see a doctor.
