Take care your blood pressure

       You go for a doctor's visit . When you see the doctor , a nurse wraps a blood pressure cuff around your arm . The cuff squeezes your arm and gives the nurse two numbers . These numbers are your blood pressure .
       Both numbers measure the amount of pressure placed on the inside of your blood vessels . The top number measures the pressure while your heart is pumping. And the bottom number measures the amount of pressure while your heart is resting between beats .
      In adults, healthy blood  pressure numbers should be 120/80 or less . These numbers show that blood moves easily through your body at the right rate . High blood pressure begins at 140/90 , putting you at risk for heart disease . The higher your blood pressure , the greater the risk .
