Taste abnormalities include two conditions, one is the taste bud abnormalities, and the other is the taste abnormalities. 1, taste buds abnormal taste buds on the tongue is to identify the taste receptors, but when the human body suffers from certain diseases or tongue nerve, tongue mucosa encounter strong physical stimulation, can interfere with the taste buds taste function, so that the taste buds occur sensory bias and failure. Thus, it will make people eat without taste and taste disorder. Since the lingual nerve of the trigeminal nerve and the bulbar nerve of the facial nerve conduct the first 2/3 of the taste information of the tongue, physical or chemical nerve damage, such as oral surgery, head and facial trauma, trigeminal neuropathy, facial nerve paralysis and facial radiation treatment, can reduce the sensitivity of taste. Intracranial tumors compressing the facial or lingual nerves, such as severe erosive cholesteatoma, rather anterior lobe tumors, and auditory neuroma, can cause taste impairment or dullness of taste sensation. Acute infections and hyperthermic diseases causing tongue inflammation can cause taste disorders due to damage to the taste buds of the tongue mucosa; digestive system diseases, endocrine diseases and chronic febrile wasting diseases can change the papillae on the tongue mucosa, affecting the sensitivity of the taste buds and leading to reduced taste sensitivity. Weakness, malnutrition, deficiency of vitamin c, D2, niacin and trace elements of zinc, anemia, protein and calorie deficiency can make the taste buds less sensitive and food is not tasty. Long-term use of certain drugs, after accumulation in the body affect the saliva components, stimulate the taste buds, can also interfere with the normal sense of taste. The degeneration of taste buds in the elderly, the taste function is weakened. Dental disease, poor oral hygiene, eating too much stimulating food, such as chili, acidic food; and addiction to tobacco and alcohol, often scraping the tongue, etc., can make the taste buds atrophy, resulting in taste disorders. 2, taste abnormalities taste abnormalities, also refers to eating when you can feel different from the normal taste; or do not eat when the mouth also has an abnormal taste sensation. Taste abnormalities are a kind of information suggesting disease, which should be noticed by doctors and patients themselves. The treatment of abnormal taste is frequently encountered in clinical practice, and there is basically nothing that can be done if such a patient is encountered in the outpatient clinic. It is only based on local, for example, what lesion inside the mouth to treat this lesion, if there is no lesion is often no good treatment measures. Chinese medicine has accumulated a lot in this area, so the ancients have accumulated a lot, and some of the modern Western medicine also has a lot of inspiration for us, so I think the treatment of taste we will speak from two aspects. One is to draw on the treatment methods of the ancients. About the abnormalities of taste, because taste is a very easy to be told a clinical manifestation, so the Inner Classic era already has a more detailed understanding, later in the treatment is also gradually in the improvement.
