Gustatory sweating is the medical term for what you might call “sweating on your taste buds.” This condition is caused by a loss of the ability to smell. It’s most common among older people who have lost their sense of smell because of senile dementia, but can also happen in younger people with conditions that affect smell or brain function, such as Parkinson’s disease and epilepsy. Most commonly these people experience an abnormal buildup of salt (sodium), which leads to excessive fluid accumulation under the skin. The body tries to rid itself of this excess moisture through secretions from glands along the neck and armpits. Because this secretory sweat does not evaporate like regular perspiration it drips off onto clothing without fully evaporating, causing staining and odors.
What causes gustatory sweating?
Many different things may cause gustatory sweating. One possible reason could be that there are changes in nerve endings within your nose or throat that trigger the release into overdrive when salt levels rise too high, just like an air conditioning unit turns up its fan speed when it needs cooling down faster than usual . A malfunctioning pituitary gland hormone called vasopressin may also contribute to excessive secretion; after all, if we didn’t need water for our bodies’ normal functions we’d never get sweaty! Sometimes patients report other symptoms such as nausea and vomiting after eating salty foods (a symptom known as post-prandial hypotension). These could be related
