Blood Pressure: Complex Trait
High blood pressure is a risk known for life-threatening sicknesses like heart disease and strokes. In the journal Nature it was revealed that, 16 previously unknown genetic regions with genes can regulate the body’s blood pressure. There are genes that regulate a group of hormones known as the angiotensin-renin-aldosterone. The renin-angiotensin-aldosterone system is responsible for regulating the body's blood pressure by a signaling pathway. The kidneys release an enzyme called renin which is stimulated by low blood pressure or certain nerve impulses. When the overall volume in the blood is increased, more blood is pumped through arteries which ...view middle of the document...

Environmental factors which cause blood pressure changes are climate, temperature and time of day. There are also age and sex differences in blood pressure. Other factors like food, tobacco, psychological stress are behavioral factors which alter blood pressure. One factor that can really harm your blood pressure is weight/diet issues. As your body weight increases, your blood pressure can rise. Also being overweight can increase the chances of developing high blood pressure than if you are at your desirable weight. You can reduce your risk of high blood pressure by losing weight. Even small amounts of weight loss can make a big difference in helping to prevent and treat high blood pressure. Smoking injures blood vessel walls and speeds up the process of hardening of the arteries. So even though it does not cause high blood pressure, smoking is bad for anyone, especially those with high blood pressure. Each cigarette you smoke temporarily increases your blood pressure. Exposure to secondhand smoke has many other effects on your cardiovascular and overall health. As you get older, the cumulative effects of an unhealthy lifestyle can build up and your blood pressure can increase. So in order to keep your body healthy you should avoid smoking, eating a diet high on salt, being overweight and drinking too much alcohol.
