The bottom line

Content: High blood pressure
High blood pressure, also called hypertension, happens when your blood pressure increases above healthy levels. High blood pressure typically develops over years and without any symptoms. Some people experience headaches, nosebleeds, and shortness of breath with high blood pressure. Over time, it can cause permanent and serious damage to the retina’s blood vessels. This can lead to retinopathy, which causes blurred vision and may result in blindness. Low blood pressure
Low blood pressure, or hypotension, is blood pressure that has dropped below healthy levels. It can be caused by dehydration, certain medical conditions and medications, and surgery. It can cause dizziness, blurred vision, headache, and fainting. Shock is a serious possible complication of very low blood pressure that requires emergency medical treatment. Stroke
A stroke is a medical emergency that occurs when the blood supply to an area of your brain is interrupted, depriving your brain tissue of oxygen.
