During the changing seasons, the temperature always fluctuates and is unpredictable. Elderly people are more susceptible to disease invasion due to decreased physical function, and are currently most susceptible to respiratory diseases with cough as the main symptom. How can elderly people stay away from coughing troubles? Identifying the cause, using targeted medication, and having a reasonable diet are key factors. Cough may hide other diseases. Elderly people often have chronic underlying diseases, and cough symptoms may hide other diseases, such as respiratory infections, pneumonia, bronchiectasis, bronchial asthma, chronic obstructive pulmonary disease, cardiovascular disease, etc. Therefore, when elderly people experience cough, it must be taken seriously and not taken lightly. Among them, pneumonia is the one that the elderly should pay special attention to. Bacterial pneumonia, viral pneumonia, mycoplasma pneumonia, and fungal pneumonia are all "frequent customers" that invade the lungs of the elderly. Once an elderly person is infected with pneumonia, their cough will become more severe. Therefore, elderly people must pay attention to prevention in their daily lives, such as wearing masks, washing hands frequently, exercising, and getting vaccinated, to avoid disease troubles. Coughing in the elderly often persists, and many elderly people have similar feelings. Coughing in youth does not take long to heal, but as people age, coughing often takes a long time. There is indeed a difference between coughing in young people and coughing in elderly people. Firstly, the causes of cough in young people are relatively simple, such as pharyngitis, bronchitis, cough variant asthma, etc., while in the elderly, the causes of cough are more complex, with multiple chronic underlying diseases coexisting, such as chronic bronchitis, emphysema, bronchiectasis, etc. Secondly, coughing in the elderly is often more stubborn and persistent than in young people. Treating cough is a "protracted battle", which may be due to the weakened immune system of elderly people, who are susceptible to bacterial invasion. Moreover, the respiratory defense mechanism of elderly people is not as strong as that of young people, and they are more prone to coughing. Finally, compared to young people, some elderly people have less obvious cough symptoms, which are temporarily unrecognizable and can easily delay treatment. This may be related to the decline in respiratory system function and weakened cough reflex in elderly people. Elderly people should pay more attention to their own bodies. Based on the characteristics of coughing, selecting treatment drugs for elderly people should first seek professional doctors to identify the cause of coughing and select appropriate treatment methods. In addition, when elderly people experience coughing, they often not only "cough" but also "phlegm" or even "wheezing". At this time, treatment methods should be selected based on the characteristics of the cough. In addition to anti infection, the most important thing is expectorant treatment. If coughing is accompanied by phlegm, especially if the phlegm is sticky and difficult to cough up, you can consider using some expectorants, such as ambroxol, eucalyptus acid, and san ao tablets. If it is not accompanied by phlegm, you can choose some cough relievers, such as dexamethasone, Suhuang cough relieving capsules, strong loquat syrup, etc. If combined with cough and asthma, antispasmodic and antiasthmatic drugs such as compound methoxylamine and montelukast sodium can be used. These drugs must be used according to medical advice and must not be taken arbitrarily. It should be noted that elderly people are not recommended to use cough suppressants containing codeine, which belongs to opioid cough suppressants and has certain addictive properties, which can lead to drug dependence and have adverse effects on the body.
