It is mainly used to treat blood-related malignancies, and both the treatment process and follow-up care afterward are important.

Hypertension and Diet Management

#hypertension, #blood pressure, #blood pressure medication, #sodium, #hyperlipidemia, #diabetes mellitus, #heart

Hypertension is a condition in which blood pressure stays persistently high. Blood pressure is the force exerted on the walls of the blood vessels when the heart pumps out blood. Hypertension often causes no symptoms, so it is also called the "silent killer." If left untreated, it can lead to complications in the heart, brain, and kidneys, so evaluation by a medical specialist and steady management are needed.
