Enlarged prostate is a common clinical disease in men, which can cause abnormal urination. The cause of the corresponding condition is not completely certain, which may be related to ageing, hormonal stimulation, genetic factors, and poor living habits. 1. Age: Age is a very common cause of prostate enlargement, mainly associated with abnormal cell proliferation and hypertrophy. 2. Hormonal stimulation: prostate hypertrophy is currently considered to be affected by repeated stimulation of androgen levels, which can lead to hyperplasia of prostate cells. 3. Genetic factors: prostate hypertrophy itself has a certain family genetic tendency, affected by family genetic factors. 4. Bad habits: Smoking, drinking, sedentary and other bad habits are also causes of prostate enlargement. If you have an enlarged prostate with obvious urinary abnormalities, you need to consult a doctor for timely observation and standardized treatment under the guidance of a clinician to avoid delays in your condition.
