Adequate intake of __________ is vital for individuals with hypertension due to its relationship with sodium.
Schach [20]

Adequate intake of  Potassium is vital for individuals with hypertension due to its relationship with sodium.

High blood pressure (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.

Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure. A blood pressure reading is given in millimetres of mercury (mm Hg). It has two numbers :

  • Top number (systolic pressure). The first, or upper, number measures the pressure in your arteries when your heart beats.
  • Bottom number (diastolic pressure). The second, or lower, number measures the pressure in your arteries between beats.

You can have high blood pressure for years without any symptoms.

Uncontrolled high blood pressure increases your risk of serious health problems, including heart attack and stroke. Fortunately, high blood pressure can be easily detected. And once you know you have high blood pressure, you can work with your doctor to control it.
