Clinically, we often encounter the phenomenon of the whole family huddle to see the sugar disease, and we recently encountered a typical example. My son is 23 years old, 170 cm tall, weighing 90 kg, with a BMI of 31.14 and a large waist, typical of abdominal obesity. Recently, he suddenly felt dry mouth, drink more water, urinate more, the amount of food has not been reduced, but the person has lost weight. Because his father was in his 50s and suffered from type 2 diabetes, he used the family glucose meter to measure his son’s fasting blood glucose of 11 mmol/l. After the visit, he was diagnosed with diabetes after checking his 2-hour postprandial blood glucose of 18 mmol/l, urine ketone +-, and urine sugar of 4 +. There are two diabetics in one family, besides genetic factors, their common living habits are of more concern. This family is a combination of the southern sweet tooth and the northern meat habit, long-term high sugar, high fat, high calorie food, the three members of the family are obese body type. In addition to work pressure, neglected to exercise, the 23-year-old son will be early into the ranks of diabetes. This “second generation of sugar” is also on the rise. According to the survey, the parents are diabetic, their children’s chance of developing diabetes is 15 to 20 times higher than that of ordinary people. Genetic factors certainly play an important role in this phenomenon, but it is the life and environmental factors that play a key role. In order to break the “family circle” of diabetes, parents should teach their children by example and help them build a fortress against sugar from diet, exercise and spirituality. Eat and don’t eat. The first step is to make the family diet healthy and help children develop good eating habits at an early age. Food ratios should be balanced, with a variety of meal types and no more total calories than the body needs. Eat a diet rich in whole grains, fruits, vegetables, legumes and nuts; drink alcohol in moderation; and eat less refined grains, red or processed meats and sugary drinks. Exercise to prevent fat two generations. 60% to 80% of adults with type 2 diabetes are overweight and obese, and we often find in outpatient clinics that many of the children of these big fat people are also small fat people, and the family is not up to the weight standard. These little fatties are about to face a high risk of diabetes if they continue to put on weight. A Finnish study found that people who exercised for more than four hours a week, or up to about 35 minutes a day, reduced their risk of diabetes by 80 percent, even if they did not lose weight. Overweight people who lost 5 percent of their body weight were 70 percent less likely to develop diabetes, even if they did not exercise. Mental optimism to regulate secretion. The nervous system is often under stress, affecting the secretion of hormones that regulate blood sugar, leading to a doubling of the risk of diabetes. Stressful work and life can put people in a stressful state, and insulin resistance can occur, triggering diabetes. At this time, the care of family members for each other and the understanding of parents for their children can relieve mental stress. If your parents are diabetic, you need to check your blood sugar urgently if you suddenly have a big appetite, eat more, drink more, urinate more, and lose weight, etc. After the age of 20, you should have regular annual checkups to pay attention to your weight, blood pressure, blood lipids, and blood sugar, and after the age of 30, you should have an annual screening for diabetes-related indicators. Let the chain of diabetes end early instead of being passed on from generation to generation.
