Sinusitis is the leading cause of loss of your sense of smell, and affects people of all ages. So does sinusitis lose the sense of smell? And why does sinusitis cause loss of smell? Below we learn how the loss of smell from sinusitis works, the effects of the loss of smell, and if you have sinusitis, do you lose your sense of smell?

1. How does the sense of smell work and what is loss of smell?

You may despise your sense of smell, but have you ever wondered what it would be like if you lost your sense of smell? Total loss of sense of smell is when you can't smell a thing even if it's as sweet as a flower or a delicious food and you can even be in dangerous situations.
Have you heard the term “Anosmia”? That is the state of complete loss of sense of smell. For most people, anosmia is just a temporary problem caused by a severe stuffy nose caused by a cold. After the cold passed, their sense of smell returned.
However, for some individuals, including many elderly people, anosmia is persistent and it may indicate a more serious health condition.
Like taste, smell is part of the chemical senses. You have the ability to smell because of the olfactory sensory neurons (specialized sensory cells). Each olfactory neuron has an odor receptor. Substances around you release microscopic molecules - whether those substances are pine trees or brewed coffee. These microscopic molecules stimulate odor receptors.
When molecules are detected by neurons, the neurons send messages to your brain, identifying odors. The environment is more smelly than where you have receptors, and a molecule can stimulate a group of receptors to produce a unique expression in your brain. Your brain records these expressions as a specific smell.
There are two pathways by which smell reaches your olfactory neurons.
Through your nostrils Through a channel that connects your nose to your nasopharynx. When you chew food, it releases an aroma that uses a second channel to reach the olfactory neurons. If this channel is blocked, such as when you have a stuffy nose due to a cold or flu, the smell can't reach the sensory cells that the smell stimulates. This results in you losing a lot of your ability to perceive the taste of food. In this way, your senses of taste and smell work closely together.

2. Why does sinusitis cause loss of smell?

Sinusitis is an infection of the sinuses, your sinuses swell, obstruct the drainage process, cause mucus accumulation. The common sinuses are air-filled spaces in the bones of the face. They are located on the cheeks (upper jaw), forehead, and around the eyes. The sinuses are interconnected, connecting to the nose and throat through narrow channels called ostia. One function of the sinuses is to warm and humidify inhaled air before it reaches the lungs. The sinuses are also lined with cells that help prevent infection by producing mucus to keep dirt particles and other pollutants out.
When you have acute sinusitis, you can hardly breathe through your nose. The space around your face and eyes can swell and you often have a headache or a sharp pain in your face. The common cold is often the cause of acute sinusitis.
Unless you have a bacterial infection, most cases of acute sinusitis clear up within a week or so and home remedies may be all you need to treat the inflammation. acute sinus. Sinusitis that lasts more than 12 weeks regardless of treatment is called chronic sinusitis. Symptoms of chronic sinusitis include:
Nasal congestion Swelling, pain, and tenderness around your eyes, cheeks or forehead Toothache toothache Sinusitis headache Yellow or green mucus from your nose Bad breath Fever Reduced or lost sense of smell With chronic sinusitis and a decreased sense of smell, the inflammation interferes with your sinuses' ability to drain fluid and is the reason why you lose your sense of smell and smell.
The movement of air in the sinuses normally helps volatile molecules settle in, providing brain signals that tell you what you're tasting. As a result, a sinus infection can make it difficult for you to taste, even if you still know if something is sweet or salty. However, finer flavor nuances like the flavor of delicate soups or fine wines can be lost until you unplug your sinuses.
You may be at higher risk of sinusitis if you have:
Abnormalities in the part of your nose such as nasal polyps, deviated septum or tumors Allergic reactions such as hay fever affecting your sinuses Continue exposure to smoke from smoking or exposure to secondhand smoke Health conditions such as an immune system disorder such as HIV/AIDS or cystic fibrosis In the event that your loss of smell is due to a sinus condition, this can be treatment. Topical and oral steroids often provide pain relief. In some cases, surgery may be needed to reduce the obstruction of smell to your sensory neurons. When you are diagnosed with sinusitis, you should also be aware that the condition often requires a long-term management approach and that your ability to smell is often more or less affected.

3. How to deal with loss of smell because of sinusitis

Loss of smell can be permanent or temporary. It usually goes away over time without treatment or intervention. However, not knowing when or if your sense of smell will return can be worrying. If you want to speed up the process, there are many treatments you can try at home.
3.1. Clean your nose If your sinusitis is caused by an infection or an allergy, rinsing the inside of your nose with a saline solution can help restore your sense of smell. The olfactory epithelium is the mucous membrane at the top of the nasal cavity. This layer contains olfactory receptor cells, which contribute to your sense of smell. Clearing your nose can help reduce swelling and inflammation, helping you regain your sense of smell.
Follow these steps:
Boil one liter of water and let it cool for 10-15 minutes. Add a teaspoon of salt and a teaspoon of baking soda to the water. Then mix until dissolved. Wash hands thoroughly with soap and warm water. Ideally, you should use a sinus rinse to squeeze the solution into each nostril. Repeat these steps a few times to see if it helps restore your sense of smell. Note: Make a fresh batch of solution for each use. Never use any solution left over from the previous day.
3.2. Smell training Odor training may seem strange in improving your sense of smell, but there is some research showing that olfactory training is effective in helping patients regain their sense of smell. The idea behind the training is that people affected by anosmia can improve their sense of smell by smelling four different essential oils (lemon, rose, eucalyptus and clove) daily. This therapy can train and develop your sense of smell due to exposure to certain scents. These strong scents can stimulate the trigeminal nerve that runs through the face and nose. It is thanks to this nerve that menthol has a cooling sensation and you will experience a burning sensation when you inhale ammonia.
Various studies have shown that participants are able to detect other scents in their environment in addition to the fragrance oil used in the training.
To try scent training you will need to:
Take four empty glass jars with lids, cotton pads or aromatic strips. Pour a few drops of one of the oils onto the test strip or pad and let it sit for a few minutes for the fragrance to kick in. Skip this step if using flask. Hold the perfume bottle, pad or strip up to your nose, about 2cm away. Relax and try to breathe naturally through your nose. Try this move a few more times and rest for five minutes. Move on to the next fragrance and repeat the steps above. You should smell the train at least twice a day, once in the morning and once in the evening. Smell the fragrance for 10 seconds and avoid smelling it too strongly or for too long. Also, remember to smell other things like spices, flowers, or other fragrances that are safe to smell.

3.3. Medications If your loss of smell is caused by blockage (blockage) of your nasal passages from your sinuses or allergies, you can use a variety of treatments, but you should consult with your doctor. such as:
Decongestants: Decongestants constrict the blood vessels in the nasal passages, helping to relieve congestion. This prevents the reduction of fluid build-up in your nose. Decongestants can clear your nose and help you breathe easier and improve your sense of smell. They are available as sprays, drops, and inhalers. Antihistamines: Antihistamines can relieve nasal congestion, congestion, and other allergy symptoms. They prevent the chemical histamine - which your body produces naturally during an allergic reaction - from interacting with nasal tissues. You can get antihistamines as pills, nasal sprays, or eye drops. Steroid nasal sprays: Steroid nasal sprays reduce swelling, inflammation, and mucus in the nasal passages. They also help treat nasal polyps, which are noncancerous tumors in the lining of the nasal passages. Intranasal theophylline: According to a 2017 US study, theophylline nasal spray improved and maintained the sense of smell in 50% of participants. Oral steroids: Medrol, prednisone, and other oral steroids are effective in shrinking nasal polyps, a common cause of loss of smell. When oral steroids shrink nasal polyps, it can bring back your sense of smell because it clears the blockage.
