Both left heart failure and chronic obstructive pulmonary disease are possible.

You can take ambroxol, myrtle oil and other drugs to resolve phlegm.

If you want to find out the root cause of asthma, you'd better go to a hospital clinic and have a lung function check. Oxygen inhalation 10 hour or more every day is helpful to improve symptoms and lung function.

Too much phlegm indicates that there may be infection, which can induce heart failure and should be treated as soon as possible.

When breathing, the abdominal pressure can be increased, and the urethra of the elderly is relaxed, which is easy to overflow urine.
