World Hypertension Day is observed on 17th May every year by the World Hypertension League (WHL) in association with the International Society of Hypertension (ISH). The Theme for World Hypertension Day 2018 is "Know your Numbers," with the main goal to create awareness of hypertension (high blood pressure), its symptoms, complications and preventive measures to the community.

What is Hypertension?

Hypertension is also known as high or elevated blood pressure. According to World Health Organization, Hypertension is a condition in which the blood vessels have continuously raised pressure. Blood is carried from the heart to all parts of the body.

Every individual has blood pressure which is necessary to move blood through the arteries and provide oxygen to the tissues in the body. Blood pressure is caused by the force of blood pushing against the walls of arteries due to the contraction of the heart. Blood pressure is generally measured using an instrument known as a sphygmomanometer.
World Hypertension Day

Blood pressure is measured in terms of systolic pressure (upper value), i.e. when the heart beats while pumping the blood, and diastolic pressure (lower value), i.e. when the heart is at rest between beats.

Facts and Statistics on Hypertension

  • Globally, at least 1.13 billion adults are suffering from high blood pressure
  • Worldwide, around 10.3 million people die due to hypertension every year
  • High blood pressure increases the risk of heart disease and stroke, which are the leading causes of death
  • Nearly 75 million American adults have hypertension
  • About one in three American adults has pre-hypertension
  • In India, nearly 33-40% of the urban population and 12-17% of the rural population are affected by hypertension.

Types of Hypertension

Hypertension can be divided into;
  • Primary Hypertension which is caused by no underlying medical cause.
  • Secondary Hypertension is caused by certain conditions such as heart disease, kidney disease, endocrine disorders and so on.

Importance of DASH Diet

DASH (Dietary Approaches to Stop Hypertension) diet can be a healthy way to lower the risk of hypertension. DASH eating plan lowers the salt content from 2.3 gm per day to 1.5gm, thereby decreasing the levels of high blood pressure. The guidelines for DASH diet are given below.

Food groups

DASH (servings)

Cereals and grains






Milk (low-fat)


Meat (lean meats, poultry& fish)

2 or less

Nuts, seeds and legumes

4-5 per week
