HGH Growth Hormone Replacement Therapy Lowers Blood Pressure; several studies have shown that HGH replacement therapy improves cardiac function and lung functions appreciably. These two benefits in return help reduce blood pressure. Trials conducted on adults deficient in Growth Hormone showed that, HGH therapy can help reduce diastolic blood pressure by about 10%. In a study conducted on rats, it was observed that Growth Hormone substitution results in the activation of the NO-system (i.e. Nitric Oxide system). HGH stimulates the production of nitric oxide syntheses (NOS), which helps convert L-arginine into NO. Nitric Oxide inhibits platelet aggregation and adhesion, and causes vasodilatation by activating an enzyme which in turn, relaxes the smooth muscle cells of the arteries. Both these actions of the NO system reduce blood pressure considerably.
What is Hypertension?
The cardiovascular system comprises of the heart and the blood vessels (i.e. arteries, veins and capillaries). Arteries are essential blood vessels that transport fresh and oxygenated blood from the heart to the peripheral tissues. Since, the blood from the heart needs to reach the farthest tissue in the body, and at times has to travel against the gravitational force, the blood flowing in the arteries is under pressure. The normal blood pressure is 120/80 mm Hg (The upper limit is called the Systolic Blood Pressure i.e. the peak blood pressure when the heart squeezes the blood out, while the lower limit is the Diastolic Pressure, i.e. the pressure when the heart is relaxing in between beats).
A range of factors could result in an elevation of blood pressure. This implies that, the heart needs to push with a greater force (i.e. with more pressure) for the blood to travel in the vessels. This happens when the peripheral vascular system increases the resistance to the blood flow.
