at 40, aging begins, and many people feel less energetic. studies have also confirmed that at this age, immune function declines, levels of inflammatory factors increase, and the risk of cardiovascular and metabolic diseases begins to increase.
zheng bolon, deputy chief physician of spinal surgery at xi'an red cross hospital, said that if you are over 40 and the following seven indicators are normal, even doctors will be envious.
wang youfa, chairman of the obesity prevention and control branch of the chinese nutrition society, said:the most commonly used diagnostic standard is the body mass index [bmi = weight (kg) / height (m) squared].our country recommends that adults with a bmi greater than or equal to 24 be diagnosed as overweight, and greater than or equal to 28 as obese.
to determine whether you need to lose weight, you also need to look at these indicators:
the normal waist circumference of chinese men should be less than 90 cm and that of women should be less than 85 cm. exceeding this range is considered abdominal obesity.
measurement method: stand with your feet 25-30 cm apart. wrap the tape measure horizontally around the 0.5-1 cm point above the navel. for obese people, measure horizontally around the thickest part of the waist.
waist-to-hip ratio (waist/hipwai) can reflect the degree of central obesity.the world health organization defines central obesity as a waist-to-hip ratio greater than 0.9 for men and greater than 0.85 for women.
measurement method:stand upright with your legs together and wrap the tape measure around your hips at the widest part of your hips.
subcutaneous fat thickness
the thickness of subcutaneous fat of the abdominal wall should be less than 15 mm for men and should not exceed 20 mm for women.a professional sebum thickness meter is usually required for measurement.- normal blood pressure: systolic pressure <130 mmhg, diastolic pressure <80 mmhg;
- ideal blood pressure: systolic pressure <120 mmhg, diastolic pressure <80 mmhg.
without antihypertensive drugs, systolic blood pressure ≥ 140 mmhg and (or) diastolic blood pressure ≥90 mmhg can be diagnosed as hypertension.
fasting blood sugar over 7.0 mmol/l is considered hyperglycemia, while fasting blood sugar below 3.61 mmol/l is considered hyperglycemia.for hypoglycemia.
fasting blood sugar is between 6.1 and 7 mmol/l, which is considered prediabetes.
diabetes can be diagnosed if the value of two repeated measurements is ≥7.0 mmol/l.whether blood lipids are abnormal or not mainly depends on four indicators: total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides.
- total cholesterol：≤5.2 mmol/l;
- low-density lipoprotein cholesterol: <3.4 mmol/l;
- high-density lipoprotein cholesterol: 0.96-1.15 mmol/l for men and 0.90-1.55 mmol/l for women;
- triglycerides: 0.56~1.7 mmol/l.
ma jianhua, chief physician of orthopedics at beijing geriatric hospital, said:normal bone mineral density (bmd）osteoporosis can be diagnosed when the bone density is within -1.0sd; when the bone mass is reduced and the bone density is -1~-2.5sd lower than the peak bone mass of the same gender; when the bone density is -2.5sd lower than the peak bone mass of the same gender, it can be diagnosed as osteoporosis.chang ren, chief inspector of the laboratory department of shou county people's hospital in huainan city, anhui province, said:generally, there arethe following six indicatorsassist in assessing liver condition。
alanine aminotransferase and aspartate aminotransferase
if their levels are detected at elevated levels in the blood, it usually means that liver cells are damaged.
elevated bilirubin may indicate problems such as liver cell damage, bile duct obstruction, or hemolysis.
total protein, albumin and globulin
decreased total protein and albumin may be related to chronic liver disease, cirrhosis, etc.elevated globulins may indicate problems such as infection, autoimmune disease, or progressive liver disease.alkaline phosphatase and gamma-glutamyl transferase
an increase in this indicator may indicate diseases such as bile duct obstruction, hepatitis, cirrhosis or liver cancer.
related to the activity and severity of liver disease.in acute hepatitis, adenosine dehydrogenase may be slightly elevated; in severe hepatitis, adenosine dehydrogenase will be significantly elevated.
a decrease in cholinesterase may indicate impaired liver synthesis.
pu danlan, deputy chief physician of the endocrinology department of the affiliated cancer hospital of chongqing university, said:a routine urine test can be said to be the first choice for checking the kidneys.
when kidney function is abnormal, indicators such as the protein content in the urine or urine volume will change.
normally, the total amount of urine excreted by an adult within 24 hours is 1000~2000 ml.polyuria may occur in chronic pyelonephritis, hypertensive nephropathy, and early chronic renal failure; oliguria or anuria may occur in diseases such as acute glomerulonephritis, acute exacerbation of chronic nephritis, and acute renal failure.
normal fresh urine is light yellow, clear and transparent.the number of red blood cells in normal human urine microscopic examination is 0-occasionally seen/high power field.when there are more than 3/high-power field, it is common in acute glomerulonephritis, chronic nephritis, renal tuberculosis, renal tumors or acute cystitis.
in normal human urine microscopy, the number of white blood cells and pus cells does not exceed 5 per high-power field of view.when the value exceeds this value, it may be acute glomerulonephritis, pyelonephritis, or renal tuberculosis.
under normal dietary conditions, the ph of random urine is 4.5~8.0.in nephritis, the ph of urine decreases; in renal tubular acidosis, the ph of urine increases.
the urine protein content of normal people is extremely low. persistent proteinuria is one of the signs of kidney disease and can also reflect the progression of kidney disease.
urine microalbumin (mALB）
the presence of microalbuminuria is usually considered to be an early stage of kidney disease and a sign of early kidney damage such as diabetic nephropathy and hypertensive nephropathy.
if you want to keep all your body indicators normal, you have to start with the little things in life. eat a moderate and balanced diet, eat a variety of foods without bias; have a regular routine, get enough sleep, and avoid staying up late; exercise regularly, do what you can, and avoid sitting for long periods of time; be in a good mood, relieve stress in time, and adjust your mentality.▲
