Causes

Any factor that increases pressure against the artery walls can lead to elevated blood pressure. The buildup of fatty deposits in your arteries (atherosclerosis) can lead to high blood pressure.

Besides atherosclerosis, other conditions that can lead to elevated blood pressure or high blood pressure include:

• Obstructive sleep apnea
• Kidney disease
• Adrenal disease
• Thyroid disease

Certain medications — including birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs — also can cause blood pressure to rise temporarily. Illegal drugs, such as cocaine and amphetamines, can have the same effect.
