There are many factors that can affect your blood pressure. Some of those factors are: - Stress (Emotional, mental and physical) - Some medications can cause a rise in BP - Poor sleep habits and sleep disorders (Sleep Apnea, not enough sleep, sleep disturbances, etc.) - Body position as the reading is taken (lying down. sitting, arm not level with heart, etc.) - Also there is a condition called White Coat Hypertension . This is when a person visits a doctor and their BP goes up. It s an example of mental stress. Please remember that a persons BP can change drastically over a short period of time, often within minutes. No single reading can indicate High or Low BP. Several readings over time must be taken before there is a need for concern. Please don t be alarmed by this one reading. To help ease your mind, I have included some links to some trusted web sites. Check out the links below and relax, your BP is on the rise. I hope this brings it back down, settles your anxiety and provides some education. My information comes from my experience with 5x Bypasses in Oct. 2006. I also have High BP (Hypertension) and High Cholesterol (Hypercholesterolemia), COPD (Emphysema) and Pulmonary Fibrosis.
