Pregnant women often come to the outpatient clinic to register for treatment because they have noticed elevated blood sugar. They are very anxious and very worried about the future health of their baby and their own health. Gestational diabetes is very common, with about 1 in 8-10 pregnant women falling into the category of gestational diabetes. Gestational diabetes is simply a high blood sugar level found during pregnancy. It is also very simple to deal with, monitor your blood sugar more often, and if necessary, administer insulin therapy to control your blood sugar to the ideal state. Usually around 28 weeks of gestation, a 50g glucose test is done, and if the blood sugar is too high after taking it, a 100g glucose test is needed. Some pregnant women take 75g of glucose for the test. There are many criteria about the diagnosis, and you can ask your doctor for details. If you are diagnosed with gestational diabetes, the things you need to do are to relax, make a plan, and have close communication with your family. The general treatment is divided into the following three steps: 1. Meal sharing, the most important: according to the recommendation of the nutritionist, the total amount of food eaten throughout the day, from the original three meals per day to 5-6 meals per day, including three main meals and three extra meals. In general, most pregnant women will have a significant drop in blood sugar level after meal sharing. 2.Monitoring blood sugar, the most important: frequently measure fasting and 2h post-meal blood sugar. The fasting blood sugar of pregnant women is usually not high. Generally, the higher the blood sugar, the more times the blood sugar is measured; for those with slightly high blood sugar, it is enough to measure it once a day. If the postprandial blood glucose is in 5-7mmol/L many times, congratulate to keep trying. If it is 7-10mmol/L many times, you can choose to use insulin treatment. If it is more than 10mmol/L many times, then you are strongly recommended to choose insulin to lower your blood sugar. Insulin injection is very convenient and can be given once before each meal. There is almost no pain (as reported by patients). If you are already taking insulin, you should stay in close contact with your doctor, even if you adjust the insulin dosage according to your blood sugar. Generally, as the month of pregnancy increases, blood sugar will gradually rise and insulin dosage will gradually increase, so patients do not need to worry excessively. 3. Appropriate exercise: taking a moderate amount of walks and walking for 20-40 minutes after meals will help the blood sugar drop after meals. Many patients worry about whether they should apply insulin for life in the future after using it. In fact, there is no need to worry at all, because the majority of gestational diabetic patients, after delivery, their blood sugar will drop to normal and they can stop insulin injections. However, patients with gestational diabetes need to realize that even if their blood sugar returns to normal, the risk of developing diabetes in the future will still be significantly higher than in the general population. One third- one quarter of people with gestational diabetes will develop diabetes in the future. Therefore. After having a baby, you should pay attention to increase exercise and diet control, improve your lifestyle, and maintain an appropriate weight (normal weight Kg = height cm – 105). Only by strengthening prevention in general can we reduce the risk of developing diabetes and cardiovascular disease in the future. Diabetes is a polygenic disease, and parents who develop diabetes have an increased risk of their children developing diabetes in the future. However, this does not mean that the child will definitely be diabetic in the future. If the child maintains a healthy lifestyle, exercises more and maintains a normal weight, it will also help reduce the risk of developing diabetes.
