The enlarged prostate may shrink, and aggressive diagnosis and treatment is needed when prostate enlargement occurs. Two important pathogenic factors for prostate enlargement are old age and a functioning testicle, a common cause of urinary difficulty in older men. The most common early symptom is frequent urination, which is more pronounced at night. With the aggravation of obstruction at a later stage, urination difficulty will occur, which is manifested as delayed urination, intermittent urination, short projections, etc. Some patients will experience pain in the lower abdomen. Prostatic hyperplasia can be shrunk through treatment. Commonly used medications include alpha receptor blockers, such as terazosin, which can reduce urethral resistance and relieve urination difficulties; and 5 alpha reductase inhibitors, such as finasteride, which can shrink the prostate and reduce urination difficulties. Surgical treatment, transurethral resection of the prostate, is an option for those with severe symptoms to improve symptoms. When prostate enlargement occurs, it is necessary to actively consult the doctor, follow the doctor’s instructions for reasonable treatment, and drugs need to be reasonably applied under the guidance of the physician.
