What are the normal values of blood pressure, blood sugar, blood lipids and uric acid for people of different ages?👀👀👀

Blood pressure, blood sugar, blood lipids and uric acid are the four basic
indicators for evaluating the health of the human body. However, the values of these indicators are not fixed and it will change with age. Therefore, some people will mistakenly think that they are unhealthy when they find that the value of the index is different from the standard value after the physical examination.

What is the normal blood pressure value?

A person's blood pressure should neither be too high nor too low. Excessive blood pressure can damage organs or tissues such as the cardiovascular system and kidneys. It also increases the risk of stroke. Low blood pressure prevents sufficient delivery of oxygen and blood to all parts of the body. It can cause fatigue, weakness, dizziness, and even fainting. Low blood pressure also increases the risk of stroke. However, in fact, people's blood pressure is not always stable. A person's blood pressure can vary at different times of the day and in different physical conditions. The following is the reference value of normal blood pressure for people of various ages:

Age	Systolic blood pressure (Male)	Diastolic blood pressure (Male)	Systolic blood pressure (Female)	Diastolic blood pressure (Female)
16-20 y/o	115	73	110	70
21-25 y/o	115	73	110	71
26-30 y/o	115	75	112	73
31-35 y/o	117	76	114	74
36-40 y/o	120	80	116	77
41-45 y/o	124	81	122	78
46-50 y/o	128	82	128	79
51-55 y/o	134	84	134	80
56-60 y/o	137	84	139	82
61-65 y/o	148	86	145	83

The following table will indicate the blood pressure status represented by each blood pressure range:

Type	Systolic blood pressure	Diastolic blood pressure
Hypotension	Below 90	Below 60
Ideal blood pressure	About 120	About 80
Normal blood pressure	Below 130	Below 85
Normal hypertension	130-139	85-89
Borderline hypertension	140-149	90-94
Mild hypertension	140-159	90-99
Simple systolic hypertension	Over140	Below 90
Moderately hypertension	160-179	100-109
Highly hypertension	Over 180	Over110

However, many factors such as mood, exercise and temperature can affect blood pressure values. Therefore, a single blood pressure measurement cannot be used as a diagnostic result.

What is the normal blood glucose value?

Similarly, too high or too low blood sugar will also have adverse effects on the human body. Excessive blood glucose can cause disease in the patient's large blood vessels. These lesions include atherosclerosis in the basilar arteries, coronary arteries, aorta, renal arteries, and peripheral arteries. These patients tend to have severe atherosclerosis and high mortality. About 70 to 80% of diabetic patients die of diabetic macrovascular disease. In addition, hypoglycemia will also damage the patient's health. Hypoglycemia may lead to memory loss, slow reaction time, dementia, coma, and even death. Hypoglycemia may also induce arrhythmia and myocardial infarction in patients. People's blood glucose levels change as they eat, digest and absorb food. Therefore, fasting blood glucose and postprandial blood glucose are generally used as reference values. 

	Venous (whole blood)	Capillary	Venous (plasma)
Normal value - fasting	3.9 – 6.1
Normal values – 2hrs after meals	Below 7.8
Diabetics - fasting	Over 6.1	Over 6.1	Over 7.0
Diabetics - 2hrs after meals	Over 10	Over 11.1	Over 11.1
Impaired glucose tolerance - fasting	Below 6.1	Below 6.1	Below 7.0
Impaired glucose tolerance - 2hrs after meals	6.7 – 10.0	7.8 – 11.1	7.8 – 11.1
Impaired fasting glucose - fasting	5.6 – 6.1	5.6 – 6.1	6.1 – 7.0
Impaired fasting glucose - 2hrs after meals	Below 6.7	Below 7.8	Below 7.8

What is the normal blood lipid value?

Patients with hyperlipidemia will make the blood thicken. Blood becomes prone to deposits on the walls of blood vessels, gradually forming plaques. These plaques can gradually build up and grow and clog blood vessels. It slows or even blocks blood flow. However, blood lipid levels are not as low as possible. Some studies have pointed out that when the cholesterol level of the elderly over 70 years old is lower than 4.16mmol/L, their risk of acute cardiovascular and cerebrovascular events is similar to that of the elderly whose cholesterol level is higher than 6.24 mmol/L. The normal reference values of blood lipids are as follows:

Types	Normal values
Total Cholesterol	2.8 – 5.17 mmol/L
Triglycerides	0.56 – 1.7 mmol/L
High Density Lipoprotein (Male)	0.96 – 1.15 mmol/L
High Density Lipoprotein (Female)	0.90 – 1.55 mmol/L
Low Density Lipoprotein	0 – 3.1 mmol/L

What is the normal uric acid value?

Under a normal diet, hyperuricemia is clinically diagnosed when the blood uric acid value of males exceeds 420 μmol/L and that of females exceeds 360 μmol/L in two tests on different days. 

	The range of normal blood uric acid level
Male	237.9 – 420 μmol/L
Female	178.4 – 360 μmol/L
