 Bad smelling mucus in nose

It's normal to occasionally smell something bad. Nevertheless, a number of conditions, including those that affect the mouth, nasal passages, and sinuses, can cause a bad odor to seem to come from the inside of the nose.

The following conditions can result in a foul odor in the nose:

  1. sinusitis, both acute and chronic
  2. infection of the teeth or mouth
  3. mouth arid
  4. certain foods, beverages, and medications
  5. hallucinatory or olfactory damage-related conditions

Most illnesses that make your nose smell awful are not dangerous. However, if the offensive odor is persistent or severe, it may necessitate medical treatment and have a detrimental influence on someone's quality of life.

This article explores the causes, remedies, and preventative measures for nasal odor. We address several of the ailments that are frequently linked to an unpleasant odor in the nose below:

Chronic or acute sinusitis

  1. If someone has acute or chronic sinusitis, they could smell terrible in their nose.
  2. In the US, 31 million people get sinusitis, also known as sinus infection.
  3. The symptoms of sinusitis, such as nasal congestion and sinus inflammation, might impair one's ability to smell.
  4. Along with foul breath and unpleasant-smelling, discolored discharge from the nose and throat, the disorder can also generate bad odors in the nose.

While chronic episodes of sinusitis can continue longer than 8 weeks, acute cases typically last for 3 to 8 weeks. Sinusitis is typically brought on by a type of bacteria, though it can also be brought on by viruses, fungi, and molds.

Dental problems and poor oral hygiene

Cavities, or holes in the teeth, can hold germs that, when they decompose, generate obnoxious gases like sulfur. Cavities typically result from either dental decay or gingivitis, which can cause inflamed gums or gum disease.

Through tiny pores in the back of the mouth that connect to the sinuses, these unpleasant gases can travel and turn into foul-smelling scents, which can result in a poor odor in the nose.

A unpleasant taste or odor in the mouth can result from poor dental hygiene since it increases the amount of food particles left in the mouth that can decay.

Dental problems can also raise the chance of forming plaque, a bacterial film that is thick and can cause tooth decay and inflame the gum and gingival tissues, increasing the risk of both developing plaque and tooth decay (a condition called periodontitis).

certain beverages, foods, and medicines

Micronized compounds that heighten the sense of smell are abundant in foods and beverages.

A pathway close to where the roof of the mouth meets the nose allows molecules to go to the sinuses, which is largely responsible for our ability to enjoy the taste and fragrance of food and drink.

As our systems break down and digest foods, odors are released from all foods. But some meals, beverages, and medications, including some prescription ones, can leave a bad taste in the mouth or cause a bad smell to come from the nostrils, especially

  1. onions and garlic
  2. coffee
  3. spices in food
  4. both nitrates and nitrites
  5. amphetamines
  6. phenothiazines

Dry mouth

When the flow of saliva is inadequate, dry mouth, also known as xerostomia, can develop. Most people who have dry mouth experience constant thirst and have enlarged nasal passages.

Saliva regularly clears the mouth of particles and germs that are not desirable. Acids are also neutralized by it.

Therefore, diseases like foul breath and tooth decay are more likely to occur when there isn't enough saliva in the body.

Another typical side effect of several drugs is dry mouth. Dry mouth has several root causes, including:

  1. mouth-to-mouth breathing
  2. dehydration
  3. taking painkillers
  4. decongestants
  5. antihistamines
  6. diuretics
  7. disorders of the salivary glands, like Sjogren's
  8. syndrome

Smoking and tobacco use

Tobacco products contain chemicals that stain and weaken the teeth and gums, thus increasing the risk of tooth and gum disease. Tobacco can also give the breath an unpleasant odor.

Smoking can also reduce someone’s ability to taste and smell food properly, which may cause someone to smell odors that they perceive as foul, but which may not actually be bad.


Phantomomaniacs perceive odors that are not actually present. When a person's sense of smell is hampered by a condition, it happens.

Every person with phantomia smells something somewhat different, but most say they smell:

  1. burnt
  2. metallic
  3. similar to chemicals
  4. rotten
  5. decayed
  6. similar to feces

Only 10 to 20 percent of persons with scent issues have phantomia. But, a variety of ailments, such as the following, might result in phantomia:

  1. flu and colds
  2. sinus problems
  3. migraine attacks
  4. nasal growths
  5. epilepsy
  6. brain damage or a stroke

Several medical illnesses, including schizophrenia, Alzheimer's disease, and Parkinson's disease, result in hallucinations.

disorders of the digestive system and others

Acid reflux is one digestive disorder that can lead to poor breath and a terrible aftertaste.

A foul or peculiar smell in the nose is also typically caused by relatively benign illnesses; infrequently, however, is it connected to more systemic or significant health issues, which may include:

  1. diabetes, which could produce a pleasant odor
  2. liver illness, which could have a pungent odor
  3. renal illness, which could produce an odor similar to ammonia


The underlying disease determines the best course of treatment for a bad nasal odor.

However, there are several natural therapies that might help lessen an offensive odor in the nose.

Try making your own saltwater rinse

An unpleasant odor in the nose might be momentarily lessened by using a saltwater rinse.

Making a saltwater rinse at home involves:

  • Water should be brought to a boil, then allowed to cool.
  • While the water is still quite warm, combine 1 teaspoon (tsp) of salt and 1 teaspoon (tsp) of baking soda in it.
  • With soap and water, thoroughly wash your hands.
  • Pour some of the mixture while positioned over a bowl or sink.
  • mixture into the palm of one hand, which is cupped.
  • Sniff a little of the mixture into each nostril individually, then let it drip out of your nose as you lean over the sink. It could be beneficial to use a finger to keep the other nostril closed while sniffing.
  • Several times go through steps 4 and 5.
  • Get rid of any leftover solution.
  • A soft rubber ear bulb syringe and over-the-counter nasal saline rinse products are further options.

Keep hydrated

Conditions that lead to a bad odor in the nose might be brought on by dehydration.

Dehydration is a primary factor in many illnesses that cause a foul odor to emanate from the nose. Among other things, a person's age, activity level, and food will all affect how much liquid they require each day.

If a person's body doesn't produce enough saliva, they can attempt sugar-free candies or gums or utilize artificial saliva.

Saliva production can also be aided by foods that require extensive chewing, such as fiber-rich fruits and vegetables.

Maintain proper dental hygiene

Most conditions that lead to an offensive odor in the mouth and nose can be treated with appropriate oral hygiene. The American Dental Association has several suggestions, like:

  • Use a fluoride-based toothpaste twice a day for two minutes to brush your teeth.
  • Floss every day.
  • Use a toothbrush or tongue scraper to clean the tongue every day.
  • regular cleaning of dental instruments and dentures
  • 5 minutes after meals, chew sugarless gum.
  • Limit the intake of foods and beverages that can cause
  • booze and coffee both cause dehydration.
  • Stop smoking and using tobacco.
  • Regularly schedule cleanings and exams for your teeth.
  • Use over-the-counter drugs

Some over-the-counter (OTC) drugs may also help address diseases that lead to unpleasant nasal odors. OTC medicines consist of:

nasal spray decongestant: This can lessen nasal congestion and improve sinus discharge. The majority of nasal decongestant sprays work for three to four days.

Antihistamines: These suppress inflammation, which can facilitate the opening of blocked sinus and nasal passageways.

There are some conditions that make the nose smell foul and need medical attention. For instance, sinus or nasal infections that linger longer than 7–10 days often need for 3-–28 days of antibiotic therapy.

To help a person manage diseases that result in a foul odor in the nose, a doctor or allergist may also prescribe certain drugs or therapies, such as:

Nasal corticosteroid topical sprays: These aid in lowering sinus and nasal inflammation.

Surgery: This can fix structural issues such closed airways, polyps, or missing nasal bone.


Some lifestyle adjustments, including maintaining good oral hygiene, may help lower the likelihood of getting an unpleasant odor in the nose.

Making some lifestyle adjustments can help lower the likelihood of getting a foul odor in the nose, depending on the condition that produces it. Changes in lifestyle include:

  • observing proper oral hygiene
  • drinking water
  • consuming foods high in fiber
  • avoiding dehydrating meals and beverages like caffeine and alcohol
  • employing decongestants or antihistamines to treat
  • sinusitis or nasal irritation
  • avoiding foods and beverages that make your mouth smell awful, including garlic and onions
  • observing proper oral hygiene
  • not using tobacco products or smoking
  • speaking with a doctor about cutting back on or switching
  • drugs that could possibly cause dry mouth

undergoing routine dental examinations and treating oral or dental infections


Bad odors in the nose are typically caused by sinusitis, oral infections, as well as particular meals, beverages, and lifestyle choices.

In most cases, people can get rid of offensive odors in the nose by using natural remedies, taking over-the-counter medications, and altering their lifestyle.

A foul odor in the nostrils, however, can impair someone's quality of life and result in issues like malnutrition. It might also indicate underlying medical issues that need attention.

If a person has a severe or persistent foul smell in their nose, one that does not go away with home cures, or one that lasts for more than a week, they should speak with their doctor.
