Benign prostatic hyperplasia (BPH) is a very common condition in men in which the prostate enlarges with age, narrowing the urethra and causing urinary symptoms. The prevalence rises with age, affecting about 50% of men in their 50s and 60% of men in their 60s. Without treatment, it can lead to complications such as acute urinary retention or kidney failure, so if you have symptoms, please consult a urologist.

Fine Dust (Particulate Matter) and Health

#particulate matter, #fine particulate matter (PM2.5), #Asian dust (yellow dust), #respiratory system, #mask, #KF80, #KF94, #asthma, #air pollution, #dry cough, #minor cough, #persistent cough

Fine dust consists of tiny particles floating in the air. It directly affects the respiratory tract, including the nose, bronchi, and lungs, and can also harm the whole body, including the heart, brain, and blood vessels, through the bloodstream. Long-term exposure increases the risk of asthma, reduced lung function, and cardiovascular and cerebrovascular disease. On days when fine dust levels are high, limit outdoor activities, and people at high risk are advised to wear a health protection mask.
