Hoarseness is a common clinical condition. In addition to certain inflammatory diseases, vocal cord nodules or polyps, vocal cord paralysis and other causes, the improper use of some drugs can also cause hoarseness, which is medically called “pharmacological voice abnormality”. When applying these drugs, patients should pay close attention to the changes in their voices, especially teachers, announcers and singers should use these drugs with caution. Common drugs that cause hoarseness are: Sex hormones: Some women use certain hormones to treat diseases, such as methyltestosterone (methyltestosterone), testosterone propionate (testosterone propionate), nandrolone phenylpropionate (norethindrone phenylpropionate), etc. Improper use or excessive dosage can cause the phenomenon of male voice, low, coarse and hoarse voice in women. Anti-allergic drugs: such as promethazine (fenagan), benadryl, chlorpheniramine and other anti-allergic drugs, the main treatment of allergic diseases and motion sickness, if the dosage is too large or the duration of the drug is too long, it will make the patient’s oral mucosa under the saliva secretion decrease, which will lead to dry mouth, resulting in hoarseness. Anticholinergics: such as belladonna tablets, atropine, ranuncine, ranuncine, bromopamine tylenol (probenecid) and other anticholinergic drugs, with antispasmodic, analgesic, inhibition of glandular secretion and other effects, can be used to treat peptic ulcer, gastritis, gastrointestinal biliary colic and many other diseases, but take too many times, there will be a dry throat, and cause hoarseness. Chinese herbs: Some warm herbs, such as ephedra, cinnamon stick, hosanna, dried ginger, atractylodes, atractylodes, deer antler, ginseng, etc., and certain tranquilizing herbs, such as stone cassia and magnet, can produce dryness of the oropharynx and cause hoarseness when taken for too long. Hoarseness corresponds to different clinical manifestations of the disease Congenital laryngeal malformation: Hoarseness occurs after birth due to laryngeal webbing, vocal cord dysplasia, and arytenoid cartilage displacement. Inflammatory hoarseness: acute laryngitis and laryngeal diphtheria cause acute onset of hoarseness, with marked chills and general discomfort. In chronic laryngitis, vocal cord nodules, and laryngeal nodules, hoarseness develops slowly and lasts for a long time. Hysterical hoarseness: there is no lesion in the larynx itself, but the onset is sudden and the degree of hoarseness varies, some can only whisper, some completely lose their voice, and the cough sound is normal. Chronic laryngitis hoarseness: It is characterized by slow onset, intermittent hoarseness in the early stage, followed by persistent hoarseness, and sometimes mucous sputum in the larynx. Laryngeal trauma hoarseness: there is a history of trauma, early hoarseness, bleeding, subcutaneous emphysema, dyspnea, painful swallowing, and later hoarseness and dyspnea are aggravated by scar formation. Laryngeal papilloma hoarseness: It is manifested as hoarseness gradually worsens with the growth of tumor, with a slow course and easy recurrence, and in severe cases, it blocks the vocal chambers and laryngeal obstruction occurs. Five daily habits to prevent hoarseness 1, drink more water If you need to keep talking all day, it is best to pause every 10 minutes to replenish warm water. 2, adequate rest People who need to talk for a long time, usually try to avoid long time talking and singing KTV and other activities. 3, diet control Do not eat fried, spicy and stimulating food.
