Modern people live a stressful life with a particularly rich diet and lack of exercise, so what is usually checked during a physical examination includes blood sugar, blood lipids, blood pressure, liver function, kidney function, electrocardiogram, as well as ultrasound examinations of the liver, gallbladder, pancreas, spleen and kidney, and chest CT examinations. When blood sugar is high, people are prone to diabetes, blood pressure is high, hypertension is high, hyperlipidemia is high, and arteries are prone to plaque formation, which promotes the occurrence of cardiovascular and cerebrovascular diseases. Electrocardiogram can check whether there is insufficient blood supply to the heart muscle and arrhythmia, for example, some people suffer from premature ventricular contractions and often feel panic and chest tightness. In addition, ultrasound of liver, gallbladder, pancreas, spleen and kidney can check for liver cysts, gallbladder stones, hepatic hemangioma and cirrhosis.
