The loss of the ability to smell and other unpleasant symptoms sometimes frighten patients with coronavirus infection. We will find out the reason why the sense of smell and taste disappear with the coronavirus. Main Causes Respiratory infections have characteristic symptoms: cough, fever, nasal congestion. But the coronavirus, which has spread throughout the planet relatively recently, has additional signs that may seem unusual. Most of those infected with COVID-19 complain of a dullness of the sense of smell or its complete loss, as well as a distortion of taste. The main reasons why many people lose their sense of smell and taste with coronavirus infection: In the early days of illness, the coronavirus infects the mucous membranes of the nose and throat. For this reason, the mucous membrane in them swells. At the same time, the olfactory and taste receptors are affected. In rare cases, the cause may be damage to the area of the brain that is responsible for the perception of taste and smell. The sense of smell can disappear in cases where the nerve endings are affected, or there is a dysfunction of nerve impulses, which is transient. Sometimes the appearance of these phenomena is facilitated by damage to the structure of small capillaries passing next to the olfactory receptors. Loss of smell and habitual taste sensations is generally not a cause for alarm, as it goes away on its own after a while and does not generally affect the state of health. Only in 5% of cases, according to statistics, emergency assistance is required against the background of anosmia, when respiratory failure joins. Doctors believe that the inability to fully feel the taste of food in the absence of susceptibility to odors is quite natural. When do symptoms appear and how long they last? There are major factors that affect the timing of the loss of odor susceptibility in COVID-19. About half of patients report that problems with tastes and odors appear 3-4 days after infection. Other patients call the 7-12th day after the detection of the pathogen in the body. But this does not mean that it is during this period that this symptom can appear in anyone who has become infected, since the ailment is different for everyone. What affects the timing of the onset of the symptom: The form of the disease. If we have to talk about a latent course, the countdown can be carried out from the period of confirmation of infection by means of a test. Individual characteristics of the immune system. The symptom in question may appear suddenly. But patients also note cases when problems with taste and smell are increasing gradually. If there are no accompanying complications, including nasal congestion, the sense of smell can be restored in a period of 1 to 2 weeks. If there was a complicated flow, then it may take longer for the function to return. For people with complex COVID-19, it can take 5 to 6 weeks to recover their sense of smell and taste. Even those patients who breathe freely through their nose can experience problems with smell. That is, a person breathes unhindered, but cannot pick up odors. Moreover, a closer examination of the nasal mucosa shows that it is edematous. This prevents the smell components from reaching the olfactory receptors. As the body fights the coronavirus, the edema decreases, and therefore the receptors restore their function effectively. This takes longer if there is extensive inflammation. In this case, the pathological process can affect adjacent tissues.During the period when a person is already beginning to recover, a slight distortion of the sense of smell may be noted. This is a situation when the patient picks up certain odors in different ways. Often, patients say that when breathing was restored, they felt unusual odors. The main ones are carbon monoxide, a smell reminiscent of bleach, and other disinfectants, sewer odors. How to get rid of an unpleasant symptom As with any other respiratory pathogen, you should regularly rinse your throat and use seawater-based nasal preparations. Decoctions of medicinal plants with anti-inflammatory properties also have a good effect. All this together will help to restore the ability to smell smells as soon as possible and make breathing more comfortable. Of the drugs, "Chlorhexidine" and "Miramistin" are recommended. You can also consult with your local therapist to find any other alternative remedy. If you have significant nasal congestion, you can use a saline solution or instill vasoconstrictor drops. If you feel a burning sensation and dryness, saline will help to irrigate the nasal passages every 2 hours. You can also use a solution prepared at home. To do this, take table salt and boiled water in the amount of 1 tbsp. l. for 1 liter. Taking medications with zinc, vitamins and B12 will have an additional supportive effect on the body. Also, water procedures, especially a contrast shower, help to quickly restore nasal breathing and susceptibility to odors. Steam inhalation warms up the nasal passages and is especially recommended for nasal congestion and runny nose. Thanks to this, the mucous tissue of the nasal passages is moistened, blood flow in them increases, respectively, swelling and irritation can be removed faster. Steam inhalation is also an excellent method of disinfecting inflamed areas. Results Problems with smell and taste in coronavirus are explained by damage to the mucous membranes of the upper respiratory tract in the first days of the disease. These symptoms make themselves felt in most cases on the 3-4th day after infection. They are usually not dangerous and go away on their own as they recover.
