Healthy aging Sometimes loss of taste and smell contributes to depression. Loss of taste and smell also might tempt you to use excess salt or sugar on your food to enhance the taste — which could be a problem if you have high blood pressure or diabetes. If you're experiencing loss of taste and smell, consult your doctor. Although you can't reverse age-related loss of taste and smell, some causes of impaired taste and smell are treatable. For example, your doctor might adjust your medications if they're contributing to the problem. Many nasal and sinus conditions and dental problems can be treated as well.

- Oral cavity and mucosal disorders including oral infections, inflammation, and radiation-induced mucositis can impair taste sensation. The site of injury with radiotherapy is probably the microvilli of the taste buds, not the taste buds themselves, since taste buds are thought to be radioresistant.

- Poor oral hygiene can mean that teeth and gum problems such as gingivitis can cause a bad taste in the mouth. Colds, allergies and sinusitis, for example, that cause congestion in the nasal passages can reduce the sense of smell, thereby reducing the ability to taste food flavours.

- Another cause of loss of smell and taste may be upper viral or respiratory infections. Sinusitis or blocked nasal passages cause a blockage in air flow; this reduces the amount of aromas reaching the smell receptors.

Smoking causes damage to the nasal membranes and reduces one's ability to identify odors. 2  Foods will also become tasteless as a result of smoking and one may even lose his/her ability to smell aromas. 3  Certain nervous system diseases or radiation treatment for cancer patients may result in a lack of taste and smell.

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.

Smell and Taste Disorders: A Primary Care Approach Another mechanism of taste loss is damage to one or more of the neural pathways innervating the taste buds (e.g., subsequent to viral Bell's palsy or dental or surgical procedures).

Loss of Taste Sensation: Symptoms & Signs The decreased ability to taste certain types of foods is known medically as hypogeusia; the absence of taste entirely is termed ageusia. 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 or upper respiratory infection can result in a decrease in taste sensation.
