With the introduction of the “comprehensive two-child” policy, the era of two children has finally arrived in full swing! The netizens have been discussing the “second child” like a flood. The network on the second child of all kinds of news, constantly flooded with families want to have two children, because of a variety of reasons, to be or not to be people torn. However, the most important point is that whether you have a second child or not, you should consider it under the premise of health and safety. The opening of the second child policy will increase the number of senior pregnant women. Among them, advanced pregnancy is the main risk factor for gestational diabetes, which is a manifestation of diabetes at a specific time – during pregnancy. Due to the increased secretion of sex hormones, growth hormone, thyroxine and adrenocorticotropic hormone in women during pregnancy, all of these hormones can have an antagonistic, or antagonistic, effect on insulin, resulting in insulin sensitivity. According to the survey, the risk of gestational diabetes in second-time mothers over 40 years old is 8.2 times higher than that of pregnant women between 20 and 30 years old. This is because, compared to younger mothers, older or even senior mothers are more prone to obesity, which is an important risk factor for the development of reduced glucose tolerance and diabetes, because of the gradual decline in body functions and slowed metabolism. At the same time, it is important to emphasize here that mothers of second children should not ignore the potential risks associated with high birth rates and poor reproductive history. Because of the specific endocrine and metabolic changes during pregnancy, it is an important factor in the development of gestational diabetes. If you have gestational diabetes in your first child, you are more likely to develop the disease when you have a second child. Poorly controlled gestational diabetes can lead to serious immediate and long-term complications and comorbidities in the mother and fetus. Finally, it is important to remember that glucose monitoring is required after gestational diabetes has been identified, and the most common and feasible method is self-fingertip glucose monitoring. The frequency of glucose monitoring is determined by the fluctuation of blood glucose. The seven-point method of blood glucose monitoring is recommended at the beginning, with measurement times of half an hour before three meals, two hours after three meals and once at night before bedtime. When dizziness, dizziness and other discomforts occur, the possibility of hypoglycemia should be considered, and blood glucose should be measured promptly and treated early. The frequency of blood glucose monitoring can be reduced to 4 times a day or even 1 day a week or 2 times a day when blood glucose reaches the treatment target and is stable, i.e. monitoring fingertip blood glucose half an hour before breakfast and 2 hours after breakfast. However, the number of times of blood glucose monitoring should be determined according to the blood glucose situation. Although the danger of gestational diabetes is serious, mothers-to-be should not worry too much, 90% of patients can control their blood sugar within a reasonable range through diet adjustment and proper exercise. It is understood that exercise therapy is also one of the preventive and comprehensive treatment measures for gestational diabetes. Through appropriate exercise, it can reduce the insulin resistance underlying pregnancy, which has an important role in maintaining the stability of blood sugar level and reducing the use of hypoglycemic drugs.
