What is hypertension and why we care
Hypertension, or high blood pressure, is the leading cause of heart disease and stroke, and it causes other severe health conditions as well, such as peripheral vascular disease, renal impairments, retinal hemorrhage and visual impairment. More than 10 million individuals die worldwide every year due to hypertension — this is over 12% of all deaths! Almost one out of three adults in the world has hypertension. Despite the fact that there are several effective, low cost, low risk treatments for hypertension, less than 15% of the people who have hypertension have it under control. This can be due to a person being unaware of their condition (hypertension has no symptoms), maintaining an unhealthy lifestyle, not having access to medications, or being unable to afford them, or simply forgetting to take their medicines.
What we do
We are a diverse group of doctors, scientists, nutritionists and advocates who seek to improve the worldwide situation related to hypertension. We hope to provide research evidence that can influence policy and practice that improves hypertension screening, diagnosis and management. We hope to increase awareness of this condition and its treatment options in individuals, as well as for healthcare providers and those people in power positions within governments who can help institute policies that will reduce the burden of hypertension across the globe.
