• Illegal pills, which includes cocaine and amphetamines
Risk factors
High blood strain has many hazard factors, along with:
• Age. The chance of excessive blood pressure increases as you age. Until approximately age sixty four, high blood pressure is more commonplace in men. Women are more likely to expand high blood stress after age sixty five.
