People with diabetes will feel this way, but not everyone will appear. Diabetic people drink too much, are thirsty, urinate too much and lose weight.
As the saying goes, "the nose is fragrant and the tongue tastes five flavors." The information of sour, sweet, bitter, spicy and salty is transmitted through tiny nipples on the tongue surface, which are called taste cells of tongue buds, and then excited by the taste center of cerebral cortex. The whole taste analysis activity is completed by the feedback loop neurohumoral system. But some people will have a strange smell in their mouths when they eat, or they will feel abnormal smell in their mouths when they don't eat. This often implies that you may have some kind of disease.
Tongue taste bud lesions, neuropathy, etc. This may also happen.
We can identify and observe health through the window of taste. However, when analyzing the relationship between abnormal taste and diseases, we must also pay attention to the following two points: First, abnormal taste is related to age, gender, mood, temperature and other factors, and only after these factors are excluded can it be related to diseases. For example, the sensitivity of taste varies from person to person, children are stronger than adults, young people are stronger than the elderly, and women are stronger than men; The same person, evening is better than morning. Emotion is also related to taste. When you are angry, afraid, anxious, sad or tired, your taste will decrease. Long-term hunger will temporarily cause the taste to fail, and the taste of food will be poor; Temperature will also affect taste, and human taste sensitivity is the highest between 20-30℃. In addition, smoking or drinking, lack of sleep, etc. It can also lead to abnormal taste. Second, abnormal taste is sometimes related to poor oral hygiene or temporary influence of external substances on taste buds. These are not within the scope of taste variation. For example, some toothpastes contain sodium dodecyl sulfate, which can sweeten the sour taste in orange juice. After tetracycline tablets chews and swallows, the bitter taste on the tongue surface can be changed into a metallic taste for a period of time, which cannot be removed even by gargling with water and scraping the tongue coating.
