Ask the Mayo Clinic: Why do we lose our sense of taste and small as we age? A: A reduced sense of smell (hyposmia) -- and less often taste (hypogeusia) -- are common conditions that are more likely to occur as we get older. In fact, some loss of taste and smell occurs normally with aging. The nerves and nerve endings that send smell and taste signals to the brain can degenerate as we age. The senses of smell and taste are rarely lost simultaneously. Loss of the sense of smell is more common. Because our sense of smell plays a critical role in the appreciation of flavors, loss of our sense of smell frequently gives the perception that our sense of taste is lost or greatly diminished.

What Is Anosmia? Anything that interferes with these processes, such as nasal congestion, nasal blockage, or damage to the nerve cells themselves, can lead to loss of smell. The ability to smell also affects our ability to taste. Without the sense of smell, our taste buds can only detect a few flavors, and this can affect your quality of life. Anosmia Causes Nasal congestion from a cold, allergy, sinus infection, or poor air quality is the most common cause of anosmia.

Loss of Taste in the Elderly Many older people believe that there is nothing they can do about their weakened sense of taste. Depending on the cause of your problem, your doctor may be able to suggest ways to regain your sense of taste or to cope with the loss of taste. In many cases, the loss of taste turns out to be a loss of smell.hen an elderly person loses taste, it can cause a loss of appetite, weight loss, poor nutrition, weakened immunity, and even death. Normal taste occurs when molecules released by chewing or the digestion of food stimulate special sensory cells in the mouth and throat.

Taste Buds Decline With Age -- Link With Diabetes? June 25, 2014 (Chicago) -- The number of taste buds on the tongue decreases as you age. This may be important because the fewer the taste buds, the higher your fasting blood sugar level, new research shows. This could be part of the reason there are more older adults with type 2 diabetes now, suggests Chee W. Chia, MD, of the National Institute of Aging (NIA).

It's Right Under Our Noses: The Importance of Smell to Science and our Lives The fact is that people who lose their sense of smell are deprived of taste and important aspects of functionality-there has even been research tying the loss of smell to Alzheimer's disease and memory loss. Anosmia is the condition in which the sense of smell is lost (1).

Study Warns That Losing Your Sense of Smell May Mean You May Not Live Much Longer Loss of olfactory function may “serve as a bellwether for slowed cellular regeneration or as a marker of cumulative toxic environmental exposure”. People who exercise are less likely to lose their sense of smell with age than those who do not.

- Nose or sinus problems might make you lose your sense of smell, for a little while or even a long time. Your sinuses might be swollen or polyps (tiny growths) might block your nose passages. Infections (like colds or flu) or a head injury might also make you lose your ability to smell. Parkinson's disease or Alzheimer's disease can make people lose their sense of smell. Infection or inflammation in your mouth can cause loss of taste. (Inflammation means redness and swelling.) Head injury and Bell's palsy can also affect the ability to taste.

Smell - impaired The loss of smell can occur with conditions that prevent air from reaching smell receptors located high in the nose, or loss of or injury to the smell receptors. Loss of smell is not serious, but can sometimes be a sign of a nervous system condition. Temporary loss of the sense of smell is common with colds and nasal allergies, such as hay fever (allergic rhinitis). It may occur after a viral illness. Some loss of smell occurs with aging. In most cases, there is no clear cause, and there is no treatment. The sense of smell also enhances your ability to taste. Many people who lose their sense of smell also complain that they lose their sense of taste.

Anosmia A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the olfactory nerve or damage to brain areas that process smell (see olfactory system).

Mayo Clinic Medical Edge: Age-related changes to taste and smell a common occurence Age-related changes to taste and smell occur gradually over time, and there's no way to reverse those changes. In some cases, however, loss of taste and smell may not be a product of aging alone. Nasal and sinus problems -- such as nasal polyps, allergies or sinusitis -- can lead to a decrease in these senses.

Smell & Taste 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.

What Is Anosmia? Fortunately, for most people, anosmia is a temporary nuisance caused by a severely stuffy nose from a cold. Once the cold runs its course, a person's sense of smell returns. But for some people, including many elderly, the loss of a sense of smell may persist. In addition, anosmia can be a sign of a more serious medical condition. Any ongoing problems with smell should be checked out by a doctor.

- 1 A gradual loss of smell and taste may be due to a cold/flu or sinus infection. 2  If after the cold or sinus infection has cleared up, your sense of smell and taste has not returned, it is important that you visit your GP so that he/she can identify any underlying cause for your loss of smell or taste. A trauma to the head may lead to a partial or permanent loss of smell as the nerves responsible for smell may be damaged or contain scar tissue. 2  In rare cases, a loss of smell may be due to a non-malignant brain tumor. 3  Gingivitis or gum diseases may predispose one to having a loss of smell or taste.

- A decrease in the number of taste buds. Changes in the way the nervous system processes the sensation of taste. This may cause a decline in the awareness of taste. A decreased amount of saliva or an increased stickiness of saliva. Changes in the tongue, making it harder for flavors to reach the taste buds.

Loss of Taste Sensation: Symptoms & Signs Dysgeusia refers to the presence of a metallic, rancid, or foul taste in the mouth. Taking certain medications can also interfere with the ability to taste. Some loss of taste sensation also occurs during the normal aging process, so elderly people may complain of decreased ability to taste foods. Sometimes, having a cold, sinus infection, strep throat, or upper respiratory infection can result in a decrease in taste sensation. REFERENCES:
