Smell and taste contribute to our enjoyment of life by stimulating a desire to eat – which not only nourishes our bodies, but also enhances our social activities. When smell and taste become impaired, we eat poorly, socialize less, and feel worse. Smell and taste warn us of dangers, such as fire, poisonous fumes, and spoiled food. Loss of the sense of smell may indicate sinus disease, growths in the nasal passages, or, at times, brain tumors.\nHow Do Smell and Taste Work?\nSmell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat. These cells transmit messages to the brain, where specific smells or tastes are identified.\nOlfactory (smell nerve) cells are stimulated by the odors around us-the fragrance from a rose, the smell of bread baking. These nerve cells are found in a tiny patch of tissue high up in the nose, and they connect directly to the brain.\nGustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain.\nOur body’s ability to sense chemicals is another chemosensory mechanism that contributes to our senses of smell and taste. In this system, thousands of free nerve endings-especially on the moist surfaces of the eyes, nose, mouth, and throat-identify sensations like the sting of ammonia, the coolness of menthol, and the “heat” of chili peppers.\nWhat Causes Loss of Smell and Taste?\nScientists have found that the sense of smell is most accurate between the ages of 30 and 60 years. It begins to decline after age 60, and a large proportion of elderly persons lose their smelling ability. Women of all ages are generally more accurate than men in identifying odors.\nSome people are born with a poor sense of smell or taste. Upper respiratory infections are blamed for some losses, and injury to the head can also cause smell or taste problems.\nLoss of smell and taste may result from polyps in the nasal or sinus cavities, hormonal disturbances, or dental problems. They can also be caused by prolonged exposure to certain chemicals such as insecticides, and by some medicines.\nTobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify odors and diminishes the sense of taste. Quitting smoking improves the smell function.\nRadiation therapy patients with\ncancers of the head and neck\noften complain of lost smell and taste. These senses can also be lost in the course of some diseases of the nervous system.\nPatients who have lost their larynx (voice box) commonly complain of poor ability to smell and taste. Laryngectomy patients can use a special “bypass” tube to breathe through the nose again. The enhanced air flow through the nose helps smell and taste sensations to be re-established.\nHow Are Smell and Taste Loss Diagnosed?\nThe extent of loss of smell or taste can be tested using the lowest concentration of a chemical that a person can detect and recognize. A patient may also be asked to compare the smells or tastes of different chemicals, and how the intensities of smells and tastes grow when a chemical concentration is increased.\nSmell-Scientists have developed an easily administered “scratch-and-sniff” test to evaluate the sense of smell.\nTaste-Patients react to different chemical concentrations in taste testing; this may involve a simple “sip, spit, and rinse” test, or chemicals may be applied directly to specific areas of the tongue.\nCan These Disorders Be Treated?\nSometimes certain medications are the cause of smell or taste disorders, and improvement occurs when that medicine is stopped or changed. Although certain medications can cause chemosensory problems, others-particularly anti-allergy drugs-seem to improve the senses of taste and smell. Some patients, notably those with serious respiratory infections or seasonal allergies, regain their smell or taste simply by waiting for their illness to run its course. In many cases,\nnasal obstructions\n, such as polyps, can be removed to restore airflow to the receptor area and can correct the loss of smell and taste. Occasionally, chemosenses return to normal just as spontaneously as they disappeared.\nHow Do You Cope with Smell or Taste Problems?\nIf you experience problems in smelling or tasting, try to identify and record the circumstances surrounding it. When did you first become aware of it? Did you have a cold or flu then? A head injury? Were you exposed to air pollutants, pollens, danders, or dust to which you might be allergic? Is this a recurring problem? Does it come in any special season, like hayfever time?\nBring all this information with you when you visit a physician who deals with diseases of the nose and throat (an otolaryngologist-head and neck surgeon). Proper diagnosis by a trained professional can provide reassurance that your illness is not imaginary. You may even be surprised by the results. For example, what you may think is a taste problem could actually be a smell problem, because much of what you taste is really caused by smell.\nDiagnosis may also lead to treatment of an underlying cause for the disturbance. Remember, many types of smell and taste disorders are reversible.\nFlavor\nFour commonly identified taste sensations:\nsweet\nsour\nbitter\nsalty\nCertain tastes combine with texture, temperature, and odor to produce a flavor that allows us to identify what we are eating.\nMany flavors are recognized through the sense of smell. If you hold your nose while eating chocolate, for example, you will have trouble identifying the chocolate flavor, even though you can distinguish the food’s sweetness or bitterness. This is because the familiar flavor of chocolate is sensed largely by odor. So is the well known flavor of coffee. This is why a person who wishes to fully savor a delicious flavor (e.g., an expert chef testing his own creation) will exhale through his nose after each swallow.\nTaste and smell cells are the only cells in the nervous system that are replaced when they become old or damaged. Scientists are examining this phenomenon while studying ways to replace other damaged nerve cells.\nCall Ear, Nose & Throat Specialists of Illinois for more information or to schedule an appointment.\n(847) 674-5585","attrs_markdown":"[Skip to content](https:\/\/entillinois.com\/ent\/smell-taste-loss\/#main)\n\nJavascript is required for this site to work properly.

Search # Loss of Smell or Taste Posted on December 19, 2022 by Ear, Nose and Throat Specialists Of Illinois Problems with these senses have a big impact on our lives. Smell and taste contribute to our enjoyment of life by stimulating a desire to eat – which not only nourishes our bodies, but also enhances our social activities. When smell and taste become impaired, we eat poorly, socialize less, and feel worse. Smell and taste warn us of dangers, such as fire, poisonous fumes, and spoiled food. Loss of the sense of smell may indicate sinus disease, growths in the nasal passages, or, at times, brain tumors. ## How Do Smell and Taste Work? Smell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat. These cells transmit messages to the brain, where specific smells or tastes are identified. - Olfactory (smell nerve) cells are stimulated by the odors around us-the fragrance from a rose, the smell of bread baking. These nerve cells are found in a tiny patch of tissue high up in the nose, and they connect directly to the brain. - Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain. Our body’s ability to sense chemicals is another chemosensory mechanism that contributes to our senses of smell and taste. In this system, thousands of free nerve endings-especially on the moist surfaces of the eyes, nose, mouth, and throat-identify sensations like the sting of ammonia, the coolness of menthol, and the “heat” of chili peppers. ## What Causes Loss of Smell and Taste? Scientists have found that the sense of smell is most accurate between the ages of 30 and 60 years. It begins to decline after age 60, and a large proportion of elderly persons lose their smelling ability. Women of all ages are generally more accurate than men in identifying odors. Some people are born with a poor sense of smell or taste. Upper respiratory infections are blamed for some losses, and injury to the head can also cause smell or taste problems. Loss of smell and taste may result from polyps in the nasal or sinus cavities, hormonal disturbances, or dental problems. They can also be caused by prolonged exposure to certain chemicals such as insecticides, and by some medicines. Tobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify odors and diminishes the sense of taste. Quitting smoking improves the smell function. Radiation therapy patients with [cancers of the head and neck](https://entillinois.com/ent/head-and-neck-cancer/) often complain of lost smell and taste. These senses can also be lost in the course of some diseases of the nervous system. Patients who have lost their larynx (voice box) commonly complain of poor ability to smell and taste. Laryngectomy patients can use a special “bypass” tube to breathe through the nose again. The enhanced air flow through the nose helps smell and taste sensations to be re-established. ## How Are Smell and Taste Loss Diagnosed? The extent of loss of smell or taste can be tested using the lowest concentration of a chemical that a person can detect and recognize. A patient may also be asked to compare the smells or tastes of different chemicals, and how the intensities of smells and tastes grow when a chemical concentration is increased. - Smell-Scientists have developed an easily administered “scratch-and-sniff” test to evaluate the sense of smell. - Taste-Patients react to different chemical concentrations in taste testing; this may involve a simple “sip, spit, and rinse” test, or chemicals may be applied directly to specific areas of the tongue. ## Can These Disorders Be Treated? Sometimes certain medications are the cause of smell or taste disorders, and improvement occurs when that medicine is stopped or changed. Although certain medications can cause chemosensory problems, others-particularly anti-allergy drugs-seem to improve the senses of taste and smell. Some patients, notably those with serious respiratory infections or seasonal allergies, regain their smell or taste simply by waiting for their illness to run its course. In many cases, [nasal obstructions](https://entillinois.com/nasal-polyps/), such as polyps, can be removed to restore airflow to the receptor area and can correct the loss of smell and taste. Occasionally, chemosenses return to normal just as spontaneously as they disappeared. ## How Do You Cope with Smell or Taste Problems? If you experience problems in smelling or tasting, try to identify and record the circumstances surrounding it. When did you first become aware of it? Did you have a cold or flu then? A head injury? Were you exposed to air pollutants, pollens, danders, or dust to which you might be allergic? Is this a recurring problem? Does it come in any special season, like hayfever time? Bring all this information with you when you visit a physician who deals with diseases of the nose and throat (an otolaryngologist-head and neck surgeon). Proper diagnosis by a trained professional can provide reassurance that your illness is not imaginary. You may even be surprised by the results. For example, what you may think is a taste problem could actually be a smell problem, because much of what you taste is really caused by smell. Diagnosis may also lead to treatment of an underlying cause for the disturbance. Remember, many types of smell and taste disorders are reversible. ## Flavor Four commonly identified taste sensations: - sweet - sour - bitter - salty Certain tastes combine with texture, temperature, and odor to produce a flavor that allows us to identify what we are eating. Many flavors are recognized through the sense of smell. If you hold your nose while eating chocolate, for example, you will have trouble identifying the chocolate flavor, even though you can distinguish the food’s sweetness or bitterness. This is because the familiar flavor of chocolate is sensed largely by odor. So is the well known flavor of coffee. This is why a person who wishes to fully savor a delicious flavor (e.g., an expert chef testing his own creation) will exhale through his nose after each swallow. Taste and smell cells are the only cells in the nervous system that are replaced when they become old or damaged. Scientists are examining this phenomenon while studying ways to replace other damaged nerve cells. Call Ear, Nose & Throat Specialists of Illinois for more information or to schedule an appointment.

Readable Markdown	Problems with these senses have a big impact on our lives. Smell and taste contribute to our enjoyment of life by stimulating a desire to eat – which not only nourishes our bodies, but also enhances our social activities. When smell and taste become impaired, we eat poorly, socialize less, and feel worse. Smell and taste warn us of dangers, such as fire, poisonous fumes, and spoiled food. Loss of the sense of smell may indicate sinus disease, growths in the nasal passages, or, at times, brain tumors. ## How Do Smell and Taste Work? Smell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat. These cells transmit messages to the brain, where specific smells or tastes are identified. - Olfactory (smell nerve) cells are stimulated by the odors around us-the fragrance from a rose, the smell of bread baking. These nerve cells are found in a tiny patch of tissue high up in the nose, and they connect directly to the brain. - Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat. They react to food or drink mixed with saliva. Many of the small bumps that can be seen on the tongue contain taste buds. These surface cells send taste information to nearby nerve fibers, which send messages to the brain. Our body’s ability to sense chemicals is another chemosensory mechanism that contributes to our senses of smell and taste. In this system, thousands of free nerve endings-especially on the moist surfaces of the eyes, nose, mouth, and throat-identify sensations like the sting of ammonia, the coolness of menthol, and the “heat” of chili peppers. ## What Causes Loss of Smell and Taste? Scientists have found that the sense of smell is most accurate between the ages of 30 and 60 years. It begins to decline after age 60, and a large proportion of elderly persons lose their smelling ability. Women of all ages are generally more accurate than men in identifying odors. Some people are born with a poor sense of smell or taste. Upper respiratory infections are blamed for some losses, and injury to the head can also cause smell or taste problems. Loss of smell and taste may result from polyps in the nasal or sinus cavities, hormonal disturbances, or dental problems. They can also be caused by prolonged exposure to certain chemicals such as insecticides, and by some medicines.
