    Renin is an enzyme secreted by the kidney, which is used to regulate the balance of body fluids and electrolytes

    This enzyme is part of the angiotension system that regulates blood pressure

    The change of renin level can be caused by many factors, from high salt diet to Cushing's disease

    The amount of renin in the blood can be known through simple tests, which can usually be carried out when doctors diagnose the cause of blood pressure bleeding

    Renin should not be confused with high blood pressure proteases

    High blood pressure proteases are enzymes secreted by the intestines and stomach of young mammals to help them digest milk

    It is also an active component of rennet, a substance used to produce cheese and other dairy products

    Although the two enzymes are very similar, their functions are very different, and they also come from different parts of the body

    Hypertensive proteases are related to the stomach, while renin is related to the kidney

    The kidneys respond to exercise, stress or a drop in blood pressure to produce renin

    When the enzyme enters the bloodstream, it interacts with angiotensin and causes two results

    The first is the contraction of arterioles, which causes the rise of blood pressure

    Followed by increased aldosterone production, resulting in * increased sodium retention

    When blood pressure becomes stable, renin and aldosterone are metabolized, and the body naturally stops producing them

    In some cases, the amount of renin secreted will exceed the actual need level, which will cause the patient's blood pressure to rise

    Sometimes this problem can be corrected by changing diet and reducing sodium intake

    In other cases, drugs may be needed to control blood pressure

    Before testing renin, it usually takes days or weeks to prepare in advance

    Doctors may advise patients to reduce sodium intake and avoid certain medications, which can affect normal readings

    At least 2 hours rest before the test

    Patients may also be required to perform short-term activities during the test to understand the effect of exercise on enzyme levels
