Question: What is (are) Problems with Smell ?
Answer: Our sense of smell helps us enjoy life. We delight in the aromas of our favorite foods or the fragrance of flowers. Our sense of smell also is a warning system, alerting us to danger signals such as a gas leak, spoiled food, or a fire. Any loss in our sense of smell can have a negative effect on our quality of life. It also can be a sign of more serious health problems. Aging and Smell Loss Problems with smell increase as people get older, and they are more common in men than women. In one study, nearly one-quarter of men ages 6069 had a smell disorder, while about 11 percent of women in that age range reported a problem. Many older people are not even aware that they have a problem with their sense of smell because the changes occur gradually over several years. They may not even notice that they are experiencing a loss of smell until there is an incident in which they don't detect food that has spoiled or the presence of dangerous smoke. How Our Sense of Smell Works The sense of smell, or olfaction, is part of our chemical sensing system, along with the sense of taste. Normal smell occurs when odors around us, like the fragrance of flowers or the smell of baking bread, stimulate the specialized sensory cells, called olfactory sensory cells. Olfactory sensory cells are located in a small patch of tissue high inside the nose. Odors reach the olfactory sensory cells in two pathways. The first pathway is by inhaling, or sniffing, through your nose. When people think about smell, they generally think of this pathway. The second pathway is less familiar. It is a channel that connects the roof of the throat region to the nose. When we chew our food, aromas are released that access olfactory sensory cells through this channel. If you are congested due to a head cold or sinus infection, this channel is blocked, which temporarily affects your ability to appreciate the flavors of food. Types of Smell Disorders People who experience smell disorders either have a decrease in their ability to smell or changes in the way they perceive odors. Total smell loss is relatively rare, but a decrease in the sense of smell occurs more often, especially in older adults. A decreased sense of smell may be temporary and treatable with medication. There are several types of smell disorders depending on how the sense of smell is affected. - Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. - Other people can't detect odor at all, which is called anosmia. - Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. - Still others may perceive a smell that isn't present at all, which is called phantosmia. - Smell loss due to aging is called presbyosmia.

Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. Still others may perceive a smell that isn't present at all, which is called phantosmia. Smell loss due to aging is called presbyosmia. Smell Loss May Signal Other Conditions Problems with our chemical senses may be a sign of other serious health conditions. A smell disorder can be an early sign of Parkinsons disease, Alzheimers disease, or multiple sclerosis. It can also be related to other medical conditions, such as obesity, diabetes, hypertension, and malnutrition. Getting a diagnosis early will help an individual deal better with the underlying condition or disease. Smell and Taste Smell and taste are closely linked in the brain, but are actually distinct sensory systems. True tastes are detected by taste buds on the tongue and the roof of the mouth, as well as in the throat region, and are limited to sweet, salty, sour, bitter, savory and perhaps a few other sensations. The loss of smell is much more common than the loss of taste, and many people mistakenly believe they have a problem with taste, when they are really experiencing a problem with their sense of smell. A loss in taste or smell is diagnosed by your doctor using special taste and smell tests. Smell Loss and Eating Habits When smell is impaired, people usually have problems appreciating the subtle flavors of food, and say that food is less enjoyable. Some people change their eating habits. Some may eat too little and lose weight while others may eat too much and gain weight. Either way, there may be a long-term impact on one's overall health. Loss of smell may also cause us to eat too much sugar or salt to make our food taste better. This can be a problem for people with certain medical conditions, such as diabetes or high blood pressure. In severe cases, loss of smell can lead to depression. Hazards of Smell Loss Research shows that people with a total or partial loss of smell are almost twice as likely as people with normal smell to have certain kinds of accidents. The most common types of accidents in order of frequency involve - cooking - eating or drinking spoiled foods or toxic substances - failing to detect gas leaks or fires cooking eating or drinking spoiled foods or toxic substances failing to detect gas leaks or fires If you think you have a problem with your sense of smell, see your doctor.

Question: What causes Problems with Smell ?
Answer: Problems with smell happen for many reasons, some clearer than others. Loss of smell may be permanent or temporary, depending on the cause. Effects of Aging As with vision and hearing, people gradually lose their ability to smell as they get older. Smell that declines with age is called presbyosmia and is not preventable. Age is only one of the many reasons that problems with smell can occur. Most people who develop a problem with smell have recently had an illness or injury. Common Causes The common causes of smell disorders are - sinus and upper respiratory infections - aging - smoking - nasal polyps - head injury - allergies - hormonal disturbances - dental problems - exposure to certain chemicals - numerous medications - radiation for treatment of head and neck cancers - diseases of the nervous system. sinus and upper respiratory infections aging smoking nasal polyps head injury allergies hormonal disturbances dental problems exposure to certain chemicals numerous medications radiation for treatment of head and neck cancers diseases of the nervous system. Sinus and Upper Respiratory Infections. The most common causes of smell problems are the common cold and chronic nasal or sinus infection. Respiratory infections such as the flu can lead to smell disorders. Swollen sinuses and nasal passages often result in problems with smell because the odors in the air do not have good access to the olfactory sensory cells. These conditions may cause total or partial loss of smell. The problem usually diminishes or goes away when the underlying medical condition clears up. Aging. Problems with smell become more common as people get older. A person's sense of smell generally declines when he or she is over 60. Smoking. Tobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify and enjoy odors. Nasal Polyps. Loss of smell can be caused by nasal polyps, which are small, non-cancerous growths in the nose or sinuses that can block the ability of odors to reach olfactory sensory cells high up in the nose. In rare cases, benign non-malignant tumors grow on the olfactory nerves leading to the brain, causing a loss of smell. Previous surgery or trauma to the head can impair your sense of smell because the olfactory nerves may be cut, blocked, or physically damaged. Automobile accidents are among the most frequent causes of trauma to the face and head. Allergies. If your smell disorder is caused by allergies and seasonal nasal congestion, you should avoid allergens, such as ragweed, grasses, and pet dander. Exposure to Certain Chemicals. Sometimes exposure to certain chemicals, such as insecticides and solvents, can permanently damage the sense of smell. Medications. If you are taking certain medicines, you may notice a change in your ability to smell. Certain medications, including some common antibiotics and antihistamines, can cause problems with smell. The sense of smell usually returns to normal when you stop taking the medicine. Radiation Treatment. People with head and neck cancers who receive radiation treatment to the nose and mouth regions commonly experience problems with their sense of smell and taste as an unfortunate side effect. Older people who have lost their larynx or voice box commonly complain of poor ability to smell and taste. Diseases of the Nervous System. Sometimes a problem with smell can be a sign of a more serious health problem. This might include diseases of the nervous system, such as Parkinson's disease or Alzheimer's disease. Loss of smell may be the first sign that something is wrong. Check with your doctor if you've been experiencing a problem with your sense of smell for a while. You may be able to prevent or get early treatment for a more serious health problem.

Question: What are the symptoms of Problems with Smell ?
Answer: A Reduced Sense of Smell There are several types of smell disorders depending on how the sense of smell is affected. People who have smell disorders experience either a loss in their ability to smell or changes in the way they perceive odors. Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. This smell disorder is common in people who have upper respiratory infections or nasal congestion. This is usually temporary and goes away when the infection clears up. If You Can't Detect Odor at All Other people can't detect odor at all, which is called anosmia. This type of smell disorder is sometimes the result of head trauma in the nose region, usually from an automobile accident or chronic nasal or sinus infections. It can sometimes be caused by aging. In rare cases, anosmia is inherited. If Your Sense of Smell Is Distorted Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. Sometimes people with this type of smell disorder also experience headaches, dizziness, shortness of breath, or anxiety. Still others may perceive a smell that isn't present at all, which is called phantosmia. Questions To Ask Yourself If you think you have a problem with your sense of smell, try to identify and record the circumstances at the time you first noticed the problem. Ask yourself the following questions: - When did I first become aware of it? - Did I have a cold or the flu? - Did I have a head injury? - Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic? - Is this a recurring problem? - Does it come at any special time, like during the hay fever season? When did I first become aware of it? Did I have a cold or the flu? Did I have a head injury? Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic? Is this a recurring problem? Does it come at any special time, like during the hay fever season? Bring this information with you when you visit your physician. Also, be prepared to tell him or her about your general health and any medications you are taking. Talking With Your Doctor Diagnosis by a doctor is important to identify and treat the underlying cause of a potential smell disorder. Your doctor may refer you to an otolaryngologist, a specialist in diseases of the ear, nose, and throat. An accurate assessment of a smell disorder will include, among other things, - a physical examination of the ears, nose, and throat - a review of your health history, such as exposure to toxic chemicals or injury, and - a smell test supervised by a health care professional. a physical examination of the ears, nose, and throat a review of your health history, such as exposure to toxic chemicals or injury, and a smell test supervised by a health care professional. Tests for Smell Disorders Some tests measure the smallest amount of odor you can detect. You also may receive a "scratch and sniff" test to determine how well you can identify various odors from a list of possibilities. In this test, the odor is embedded in a circular pad on a piece of paper and released when scratched. In this way, doctors can determine whether a person has a decreased ability to smell (hyposmia), the inability to detect any odors (anosmia), or another kind of smell disorder. In some cases, your doctor may need to perform a nasal examination with a nasal endoscope, an instrument that illuminates and magnifies the areas of the nose where the problem may exist. This test can help identify the area and extent of the problem and help your doctor select the right treatment. If your doctor suspects that upper regions of the nose and nasal sinuses that can't be seen by an endoscope are involved, he or she may order a specialized X-ray procedure, usually a CT scan, to look further into the nose and sinuses. When to See the Doctor If you think you have a smell disorder, see your doctor. Diagnosis of a smell disorder is important because once the cause is found, your doctor may be able to treat your smell disorder. Many types of smell problems are reversible, but if they are not, counseling and self-help techniques may help you cope.

Question: What are the treatments for Problems with Smell ?
Answer: Relief is Possible Although there is no treatment for presbyosmia -- loss of smell due to aging -- relief from smell disorders is possible for many older people. Depending on the cause of your problem with smell, your doctor may be able to treat it or suggest ways to cope with it. Recovering the Ability To Smell Some people recover their ability to smell when they recover from the illness causing their loss of smell. Some people recover their sense of smell spontaneously, for no obvious reason. Other common causes of smell loss, such as the common cold or seasonal allergies, are usually temporary. Smell is regained by waiting for the illness to run its course. In some cases, nasal obstructions, such as polyps, can be removed to restore airflow through the nasal passages and restore the sense of smell. If your smell disorder cant be successfully treated, you might want to seek counseling to help you adjust. Ask About Your Medications Sometimes a certain medication causes a smell disorder, and improvement occurs when the medicine causing the problem is stopped or changed. If you take medications, ask your doctor if they can affect your sense of smell. If so, ask if you could substitute other medications or reduce the dose. Your doctor will work with you to get the medicine you need while trying to reduce unwanted side effects. Medications That May Help Your doctor may suggest oral steroid medications such as prednisone, which is usually used for a short period of time, or topical steroid sprays, which can be used for longer periods of time. Antibiotics are also used to treat nasal infections. The effectiveness of both steroids and antibiotics depends greatly on the severity and duration of the nasal swelling or infection. Often relief is temporary. Occasionally, the sense of smell returns to normal on its own without any treatment. Steps You Can Take If you have a problem with smell, there are some things you can do. - Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return. However, you should not wait to see your doctor if you think something more serious has caused your loss of smell or you have had the problem for a while. Loss of smell can sometimes mean a more serious condition exists. Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return.

If there is a blockage or you have a chronic sinus condition, outpatient surgery may be called for. If Your Smell Loss Is Permanent If you do not regain your sense of smell, there are things you should do to ensure your safety. Take extra precautions to avoid eating food that may have spoiled. If you live with other people, ask them to smell the food to make sure it is fresh. People who live alone should discard food if there is a chance it is spoiled. Other home safety measures include installing smoke alarms and gas detectors. For those who wish to have additional help, there may be support groups in your area. These are often associated with smell and taste clinics in medical school hospitals. Some online bulletin boards also allow people with smell disorders to share their experiences. Not all people with smell disorders will regain their sense of smell, but most can learn to live with it. Ongoing Research The National Institute on Deafness and Other Communication Disorders (NIDCD) supports basic and clinical investigations of smell and taste disorders at its laboratories in Bethesda, Md. and at universities and chemosensory research centers across the country. These chemosensory scientists are exploring how to - promote the regeneration of sensory nerve cells - understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste - prevent the effects of aging on smell and taste - develop new diagnostic tests for taste and smell disorders - understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses. promote the regeneration of sensory nerve cells understand the effects of the environment (such as gasoline fumes, chemicals, and extremes of humidity and temperature) on smell and taste prevent the effects of aging on smell and taste develop new diagnostic tests for taste and smell disorders understand associations between smell disorders and changes in diet and food preferences in the elderly or among people with chronic illnesses.
