LAGOS, Nigeria (FN) — As Nigerians marked World Hypertension Day on May 17, a cardiologist at Lagos State University Teaching Hospital warned that millions may be living with high blood pressure unknowingly, putting them at risk of deadly complications.
Dr. Ramon Moronkola, a consultant interventional cardiologist, described hypertension as a “silent killer,” noting that about one in three Nigerian adults, 30 to 35 percent are hypertensive. He said many remain unaware until they suffer life-threatening conditions such as stroke, heart failure, kidney disease or heart attack.
“Hypertension often develops without symptoms or warning signs. Many individuals feel perfectly well until serious complications occur,” Moronkola said.
The theme of this year’s World Hypertension Day is “Controlling Hypertension Together: Check Your Blood Pressure Regularly, Defeat the Silent Killer.”
Moronkola explained that hypertension occurs when blood pressure remains persistently elevated above 140/90 mmHg. He stressed that regular checks with validated equipment are the only reliable way to detect the condition.
He urged Nigerians to adopt healthier habits, balanced diets, reduced salt intake, regular exercise, maintaining healthy weight, avoiding smoking, limiting alcohol and managing stress. “Simple lifestyle modifications can significantly reduce the risk of developing hypertension and its complications,” he said.
The cardiologist emphasized that hypertension is treatable and that consistent medication use reduces risks of stroke, heart attack and premature death. He cautioned patients against stopping treatment once they feel better. “The benefit of treatment lies in maintaining blood pressure control consistently over time,” he said.
Complications of uncontrolled hypertension include stroke, heart failure, kidney disease, damage to the eyes and peripheral vascular disease. Moronkola called for collective action, urging individuals, communities and government authorities to work together to tackle the growing health challenge.
