Normal and High Blood Pressure in Babies

Since children’s normal blood pressure changes from birth to adulthood, you need to know when their blood pressure is high, low, or normal.

Children can suffer high blood pressure, referred to as hypertension, just as grownups do 2 Several causes exist, ranging from genetic disease to being obese. Hypertension in a child can result in stroke, heart problems, kidney problems and long-lasting hypertension 2. American Family Physician says child hypertension is on the increase. Pediatricians usually try non-drug techniques to decrease blood pressure before resorting to medication.

Birth to Age 2

Blood pressure fluctuates after birth due to what the baby is doing, whether sobbing, sleeping or eating. It likewise differs due to the gestational age and weight of the baby, with a blood pressure above 79/54 generally thought about elevated but not necessarily requiring treatment. By the time a child is 1 year old, high blood pressure is determined by percentiles of age and height by sex. According to the National Heart Lung and Blood Institute, a child whose blood pressure is in the top 5 percent for his sex, age and height is thought about hypertensive. A 1-year-old boy of average height is thought about hypertensive when his blood pressure is 103/56. This suggests if his systolic — or top-number is 103 or greater and/or his diastolic-or bottom-number is 56 or greater, he has hypertension. For a 1-year-old girl of average height, the numbers at which hypertension begin are 104/58. All numbers in this short article remain in recommendation to a child of average height for his age. A 2-year old boy is thought about hypertensive with a blood pressure of 106/61; a 2-year-old girl is thought about hypertensive at 105/63.
