Causes of High Blood Pressure

High blood pressure is very common and it is genetically determined.

Ian del Conde, Cardiovascular Specialist at Miami Cardiac and Vascular Institute, explains humans have genes that make them retain salt, because years and years ago people who were able to retain salt tended to do better.

The problem is that this is not beneficial nowadays. "High blood pressure affects many different organs and systems in our body, including the brain", he points out.
