Gastroenterologist says sudden changes in taste may signal underlying illness

A gastroenterologist has warned that sudden shifts in the sense of taste can be a sign of health problems, even as gradual changes are considered a normal part of aging. Dr. Yekaterina Kashukh said oral health issues can directly affect taste perception, noting that a weakened sense of smell reduces the ability to distinguish flavors in familiar foods. Speaking in an interview carried by Russian media, Kashukh said that with age, metabolism, mucosal structure and digestive function can all change, while dry mouth, dental and gum diseases, and nasal congestion are among the leading causes of altered taste. She added that certain medications can leave a metallic taste in the mouth or blunt the perception of flavor. The gastroenterologist also pointed to the brain's tendency to link foods with memories and emotions, which she said can gradually shift dietary preferences. While gradual changes in taste are normal with age, Kashukh stressed that a sudden loss or marked shift may point to a medical condition. She recommended consulting a specialist to determine the exact cause and seek appropriate treatment.
