Taste - impaired. Taste impairment means there is a problem with your sense of taste. Problems range from distorted taste to a complete loss of the sense of taste. A complete inability to taste is rare. The tongue can detect sweet, salty, sour, savory and bitter tastes. Much of what is perceived as taste is actually smell. People who have taste problems often have a smell disorder that can make it hard to identify a food's flavor. (Flavor is a combination of taste and smell.) Taste problems can be caused by anything that interrupts the transfer of taste sensations to the brain. It can also be caused by conditions that affect the way the brain interprets these sensations.
What can cause tastes to change? Taste buds are constantly being replaced, so changes in health, nutrition, medications, hormones and age can all affect how they function, causing foods to taste bland or all the same, or leading to a metallic, sweet, chalky, blood-like or otherwise undesirable taste in the mouth.
