High blood pressure may cause damage to vital organs over time. Brain damage causes a stroke. Heart damage causes a heart attack. And kidney damage causes kidney failure. High blood pressure may also damage the eyes and blood vessels, causing weakening of the blood vessel walls. If a blood vessel wall balloons out, this is called an aneurysm.  Aneurysms may break and bleeding can happen.  

What causes high blood pressure? The blood pressure is determined by the amount of squeeze created by the circular smooth muscle of the blood vessels, by the speed at which the heart beats, and by the volume inside the blood vessels made up by the blood. The blood pressure will go up if there is too much squeeze from the blood vessels. It will also go up if there is excess volume in the circulation. And it will go up if the heart is stimulated to beat faster or stronger. Adrenaline, the “fight or flight” hormone, causes the heart to beat faster and the blood vessels to squeeze tighter. Therefore, too much adrenaline, as is the case with stress, can cause the blood pressure to go up. Table salt has sodium. Sodium holds on to water. So, the sodium inside blood vessels will hold on to water. Continue Reading →

Between 1.5 to two million Americans are currently diagnosed with lupus; 20 percent are children and 80 percent are girls. African American women are three times more likely to get lupus and tend to develop lupus at a younger age with more severe symptoms.

There is no single diagnostic test for lupus. Continue Reading →
