Seven out of 10 Nigerians are hypertensive.

50 per cent of this seven are unaware of their condition and the remaining half are just not bothered to seek medical help to treat this condition.

A retired Reproductive Medicine consultant at the University College Hospital, (UCH) Ibadan, Prof. Modupe Onadeko, disclosed this on Wednesday in commemoration of the World Hypertension Day 2017.

The consultant described hypertension as a condition in which the arterial blood pressure raises to high levesl from the normal level (120/80mmHg), and this, she said, is a risk factor for Cerebrovascular Accidents (CVA), also called Stroke or Heart Attack.

“Hypertension is  a medical condition called ‘silent killer’, as it does not show any clear symptoms.

“However, severe hypertension shows some symptoms incliuding headaches, sleepiness, palpitation, blurred vision, fatigue, dizziness, confusion and ringing sensation in the ears.

“Other symptoms that may manifest are: breathing difficulty and irregular heartbeat which may lead to coma.

“Hypertension is divided into two types; primary or essential hypertension and secondary hypertension, on the basis of its causing factors.

“The primary hypertension is a more common type. However, its causes are unknown.

‘’The causes of secondary hypertension include kidney damage, adrenal gland over-activity, sleep apnea syndrome, tumours and recreational drugs.

“Other causes are pregnancy-related conditions, over or wrong medications, alcoholic drinks and bad food,” she said.

Onadeko advised that people should do regular blood pressure check and adhere to doctor’s instruction on healthy diets and physical exercise.

Every year is set aside for the celebration of the World Hypertension Day globally.

The World Hypertension League (WHL), a health organization that leads many national hypertension societies worldwide, started the commemoration in 2005.

The day is set aside to increase public awareness about hypertension and the theme for this year is “Know Your Blood Pressure”.
