The Nigerian Hypertension Society (NHS) has raised the alarm that only about 10 percent of Nigerians living with hypertension are currently receiving treatment for the condition.

This was disclosed in a statement signed by the NHS President, Simeon Isezuo, to mark World Hypertension Day, observed annually on May 17. He also revealed that less than 2.5 percent of people with hypertension in Nigeria have successfully brought their blood pressure under control.

Despite the high prevalence of hypertension—affecting nearly one in three adults in urban areas and one in four in rural areas—Isezuo said that public awareness and proper management of the condition remain critically low. As a result, millions of Nigerians are at increased risk of severe health complications such as stroke, kidney failure, and heart disease.

“Hypertension can only be diagnosed by measuring blood pressure, yet many Nigerians have never had their blood pressure checked or do not have access to accurate monitoring,” Isezuo said.

This year marks the 20th anniversary of World Hypertension Day, themed: “Measure Your Blood Pressure Accurately, Control It, Live Longer!” The global event aims to raise awareness about the dangers of high blood pressure and encourage early detection and effective control.

Understanding Hypertension

Hypertension, or high blood pressure, is often referred to as a “silent killer” because it typically presents no symptoms. According to the World Health Organization (WHO), a person is considered hypertensive if their systolic blood pressure consistently measures 140 mm Hg or higher, or their diastolic reading is 90 mm Hg or higher.

Isezuo urged Nigerians to regularly check their blood pressure during clinic visits, at home, or in nearby health centers. He also recommended healthy lifestyle choices to prevent and manage hypertension, such as:

• Reducing salt, sugar, and fat intake

• Eating more fruits and vegetables

• Exercising regularly

• Avoiding tobacco use

• Drinking alcohol in moderation

A Growing Global Challenge

Globally, hypertension affects an estimated 1.28 billion adults aged 30–79, with two-thirds of cases found in low- and middle-income countries. The number of people living with the condition has nearly doubled since 1975 due to increasing exposure to risk factors.

The WHO reports that the African region has the highest prevalence of hypertension at 27 percent, while the Americas have the lowest at 18 percent. Alarmingly, around 46 percent of adults with hypertension are unaware they have it, often until serious complications arise.

While lifestyle changes can significantly help lower blood pressure, the WHO notes that many people still require medication to manage the condition effectively.
