Heart failure occurs when the heart muscle does not pump enough blood in the arteries, as the body needs. The disease can be caused by a few diseases that can affect the heart and thus, its capacity of pumping. When the heart does not effectively pump blood through the body, it returns slowly to the heart, a situation that will lead to accumulation of fluid in the lungs, or other parts of the body.
Kidneys have the ability to regulate the sodium levels. If the sodium in the body is too small, a hormone is released which increases the amount of sodium kept in your body by reducing the amount excreted in the urine. But this rarely happens “events” in our bodies, and because of this huge amount of salt that we eat. It is estimated that most people in civilized countries consume twice as much salt than the human body would normally require.
A stroke occurs when a blood vessel (an artery) that supplies blood to an area of the brain bursts or is clogged by a blood clot. Within minutes, the nerve cells in that area are affected and they can die within hours. As a result, that part of the body is controlled by the affected area of the brain which can not function properly.
