Chronic sinusitis will be shown by thick drainage that is foul in smell and taste. Here are some of the other possible causes, treatment and how to get rid of smelly mucus in the nose.

Smelly mucus in nose and throat

What could be causing smell mucus in nose and throat? The blockage or inflammation of the inside nose is a common cause for smell mucus. This kind of inflammation is caused by non-allergic rhinitis which is the inflammation of the inside of nose that isn’t caused by an allergy. Non-allergic rhinitis can be shown by symptoms such as:

  • Nasal blockage
  • Sneezing
  • Some people will experience a runny nose
  • Irritation and discomfort in and around the nose
  • Reduce sense of smell
  • Though rare, some people may develop a crust inside the nose that bleeds and produces a foul-smelling odor.

Treatment not only involves getting rid of the underlying cause but also controlling and managing the symptoms.

If for instance, non-allergic rhinitis is diagnosed as the underlying cause of the smelly mucus, there are different causes that could have led to the blocking or inflammation of the nose, a common cause is a viral infection such as a cold. Other causes will include environmental factors such as extreme temperatures, humidity, and exposure to noxious fumes.

Non-allergic rhinitis can also be caused by internal factors such as hormone imbalances like those occurring in puberty and pregnancy. The same symptoms can be shown in those who undergo hormone replacement therapy or hormonal contraception.

The other possible cause of smelly mucus is post nasal drip. The thick mucus associated with post nasal drip provides an ideal medium for the anaerobic bacteria responsible for the offensive oral odor. Post-nasal drip will not only cause smell mucus but also bad breath is otherwise known as halitosis. Dentists words that brushing or flossing won’t eliminate bad breath caused by post-nasal drip.

Post nasal drip associated with a transient cold or allergic attack can be effectively treated with a variety of home remedy that focuses on loosening, thinning and drying up mucus secretion. A commonly used remedy for this is usually drinking lots of warm fluids such as soup and herbal teas.

Treating the sources of excess mucus production and eliminating the proliferation of anaerobic bacteria that thrives in this kind of medium is the best way to prevent and get rid of smell mucus or bad breath associated with post nasal drip.

1. Sinusitis

Sinusitis is a common cause of inflamed and blocked nasal passage that could be causing the smelly mucus. It is a common condition in which the lining of the sinuses becomes inflamed. The inflammation and swelling are usually caused by a viral infection and often improves within two or three weeks.

In the United States alone, the condition affects close to 30 million people each year, this is according to a statistic by the National Institute of Allergy and Infectious Diseases. A sinusitis or sinus infection will occur when your sinuses become inflamed.

Sinuses are small air pockets located behind your forehead, nose cheekbones and eyes. They protect the body by trapping germs.  Bacteria or allergens may cause too much mucus to form, this may block the opening of your sinuses. This is the way most people will have a runny nose when they have a cold or allergy.

The buildup of mucus may encourage bacteria and germs to grow in your sinus cavity. This is what leads to viral or bacterial infection. Most of this infections are viral, they may clear in a week or two without treatment. The accumulation of the mucus in the nasal passage and throats may cause bad breath and smelly mucus.

To treat this kind of inflammations, a corticosteroid drop or spray may be used. Also known as steroids, corticosteroids are a group of medication that can help reduce inflammation.  If the swelling or inflammation persist, your health care provider may prescribe other treatment option to reduce the swelling in the sinuses.

Other symptoms such as congestion can be treated by applying a warm compress, pain can be relieved by using painkillers. Sometimes antibiotics will be used to treat mild bacterial infection accompanying the inflammation of the sinuses. For sinuses infection, watch out for the following sign and symptoms:

  • Drainage of a thick or greenish discharge from the nose
  • Nasal congestion that causes difficulties to breath
  • Pain, swelling, tenderness and pressure around eyes cheek, nose, and forehead
  • Severe headache
  • Ear pressure
  • Fever and fatigue

2. Tonsillitis-tonsil stones

Another possible cause of smelly mucus is tonsillitis. Tonsillitis is the inflammation of the tonsils. Tonsils refer to the oval-shaped pads of tissues at the back of the throat. Common symptoms of tonsillitis will include swollen tonsils, sore throats, and difficulty swallowing and tender lymph nodes on the sides of the neck.

Tonsillitis is often caused by infection with a common virus, a bacterial infection may sometimes cause the swelling too. Proper treatment will depend on the underlying cause of the infection. To get a proper treatment therefore, you need to get a prompt and accurate diagnosis. Your doctor may prescribe surgery when bacterial tonsillitis occurs frequently, fails to respond to other treatment option r results into other serious complications.

3. Post-nasal drip

PND, also known as the upper airway cough syndrome, occurs when there is excess secretion of mucus by the nasal mucosa. The excess mucus accumulates in the throat or back of the nose. Mucus is responsible for moistening and also help trap and destroy foreign invaders like bacteria and virus before they can cause infection.

With normal secretion, it is not possible for you to notice the mucus. This is because it mixes with saliva and drops harmlessly down the back of your throat and you swallow it without even noticing. When your body produces more mucus, the mucus becomes thicker than normal, this will make it more noticeable.

The accumulated mucus also provides a good environment where bacteria can thrive and reproduce, a bacterial infection is more likely to cause smelly mucus. When the excess mucus comes out of the nostrils, it becomes a running nose, when it runs down the back of your nose to your throat, it is called a postnasal drip.

Post-nasal drip can be caused by colds, flu, allergies, sinuses infection, pregnancy or changing the weather. Depending on the diagnosis, possible treatment would include:

  • Antibiotic to treat bacterial infection
  • Surgery in cases of chronic sinus disease
  • Oral medication and spray for allergies
  • Antacid when the post nasal drip causes gastric reflux disease.

Nasal polyps are soft painless, noncancerous growths on the lining of your nasal passage. They result from chronic inflammation of due to asthma, recurring infection, allergies, and sensitivity to the drug or immune disorders.

Small nasal polyps are asymptomatic, large growths or group of polyps can, however, can lead to breathing problems due to blocking nasal passage, some people will also experience lost the sense of smell and frequent infections. Though common in adults, nasal polyps can affect anyone.

  • Runny nose
  • Annoying snoring
  • Reduced sense of smell
  • Severe headache and facial pain
  • Pain in upper teeth
  • Post nasal drip

5. Rhinitis

Rhinitis is the inflammation of the mucous membrane of the nose. Just like the other possible causes of smelly mucus, rhinitis is also caused by a virus infection. The inflammation can also be caused by the common cold or by an allergic reaction such as hay fever.

In rhinitis, the mucous membrane becomes infected or irritated, it produces a discharge, congestion, and swelling of the tissues. A common cold is the most widespread form of infectious rhinitis. Depending on the causes, rhinitis can either be allergic or non-allergic. The difference is that allergic rhinitis is caused by allergies whereas non-allergic rhinitis is caused by other causes such as common cold.

Allergic rhinitis causes cold-like symptoms such as sneezing, itchiness, blocked or runny nose. These symptoms will start soon after being exposed to the allergen. Treating rhinitis will depend on the underlying cause of the inflammation. With allergic rhinitis, it is difficult to avoid potential allergens, different steps can, however, be taken to reduce exposure to the said allergen that could trigger the inflammation.

6. Snoring

When you are asleep, the mouth produces less saliva. Snoring worsen this situation by causing excessive dryness of your tongue, throat, and palate. This creates an enabling environment for bacteria to reproduce. The accumulation of sulfur compounds is what causes the bad breath and a foul odor when you wake up in the morning.

Snoring can be treated or managed at home in the following way:

  • By sleeping sideways and using a full-length pillow to try and hold your position while asleep
  • Keeping humidity level down by using a humidifier
  • Avoiding alcohol, or depressants before bed.
  • Regular excesses to keep and remain fit

7. Poor oral health-tooth decay

Poor oral health could also lead to bacterial accumulation through condition such as tooth decay or other oral disorders.

Smelly nasal discharge in adults

Anybody regardless of age can have smelly mucus at some point. In adults, the common cause is rhinitis which is the inflammation of the nasal passage. This condition is known to cause a runny, smelly discharge from the nose.

Rhinitis can be temporary when caused by an allergic reaction or chronic, where the symptoms last for more than six weeks. For mild cases of nasal blockage, the condition might resolve on its own, for chronic or severe cases, however, you will need to have professional health care provider diagnose the condition and prescribe the treatment to get rid of the blockage.

In an adult, the other cause of the smelly mucus could be sinusitis, this is the inflammation of the sinuses. Sinuses are air-filled cavities situated behind the forehead, eyes, cheekbone and bridge of the nose. They filter the air we breathe in, using mucus to trap dirt, bacteria and other potentially harmful particles.

The sinuses will become inflamed or swollen during infection or allergic reactions. When this happens, they are unable to drain the mucus from the head out of the body. The accumulation of mucus creates an enabling environment for bacterial growth and breeding. This is what leads to unpleasant smelling bacterial infection.

Infection of the sinuses will be shown by the following symptoms.

  • Obstruction and congestion of the nasal passage
  • Bad breath
  • Sore throats
  • Thick yellow or green mucus appearing in the nose or throat
  • Coughing especially at night
  • Diminished sense of taste and smell

Mild cases of Smelly mucus in adults can resolve on its own. For severe cases caused by allergic rhinitis, sinusitis or post-nasal drip, immediate medical attention is advised. Those with allergies or a weak immune system stand the highest chance developing a sinus infection.

Oral antibiotics

For sinusitis caused by virus infection, no antibiotic treatment is required. For bacterial infection of the sinusitis, an oral antibiotic may be used.

The infection can also be suspected when the condition fails to respond to other the counter nasal medication.

The acute bacterial infection will be treated by antibiotic therapy. Antibiotics will work by killing or preventing the growth of the bacteria that might cause some sinus infection.

Surgery for chronic sinusitis

Sometimes, a surgery may be done due to the complication of the sinusitis. This complication can include the development of pus in the sinus, infection of the facial one, or when abscess occurs inside the nose. The goal of the surgery is to make drainage of eh sinuses better, usually, by removing the blockage and draining of the mucus, this will mean:

  • Removing infected, swollen or damaged tissue
  • Removing the swollen bone to create a wider opening for the drainage of mucus from the sinuses.
  • Getting rid of the growths inside the nose
  • Removing a foreign object blocking the nasal passage

Surgery does not always completely eliminate sinusitis, some people will need a second operation. When treating a swollen of infected nasal passage, surgery becomes more effective when used alongside other medicine [WebMD]
