    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
