[1] Onset is generally sudden. [1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye. [1] [3]
There are several etiologies of a hypertensive crisis, including a tumor. A rare, neuroendocrine tumor called a pheochromocytoma can cause a hypertensive crisis due to elevated levels of catecholamines. [6] [7]
The high blood pressure is gradual at early stages and may take at least 10–15 years to fully develop. Besides diabetes, other factors that may also increase high blood pressure include obesity, insulin resistance and high cholesterol levels. In general, fewer than 25 percent of diabetics have good control of their blood pressure.

It can have many potential causes, including genetics, lifestyle habits, and underlying health issues. Some types of cardiovascular disease, such as some cardiomyopathies, develop due to factors ...
Conversely, treatment of hypertension seems to reduce the risk. More recently, scientists have also shown that blood pressure variability may be a better predictor of cognitive decline than ...
Primary hypertension, also known as essential hypertension, is the result of a consistent elevation of the force of blood being pumped throughout the body, whereas secondary hypertension is the result of high blood pressure due to another medical condition.> Diseases that can cause secondary hypertension include diabetic nephropathy, glomerular disease, polycystic kidney disease, cushing ...
A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys). It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD).
