It is very common for pregnant women to get hungry easily during pregnancy, partly because during pregnancy, in order to supply nutrition to the fetus, the intake is more than daily. If there is also pregnancy vomiting at this time, this will lead to a reduction in the amount of food and intake of pregnant women, pregnant women will be more likely to be hungry. In addition, if a pregnant woman with gestational diabetes, also easy to become hungry. 1, physiological reasons: during pregnancy, along with the growth and development of the fetus, the nutrition and energy required gradually increased. The food that pregnant women eat not only to meet their own needs, but also to provide sufficient nutrition to the fetus, thus leading to the phenomenon of easy hunger. Especially in the middle and late pregnancy, the fetus is in a period of rapid bone development, which requires more nutrients and energy. Therefore, pregnant women should reasonably consume protein, fat, carbohydrates, vitamins and minerals, and a nutritionally balanced diet consisting of diverse foods is important for normal fetal growth and development and improving maternal and child outcomes; 2. Pathological causes: if pregnant women experience hunger soon after eating and show symptoms of generalized soreness and weakness, excessive drinking, eating and urinating, abnormal blood sugar needs to be excluded, and after 24 weeks of pregnancy Glucose tolerance test should be done to exclude gestational diabetes. If there is any abnormality, it is necessary to actively control blood sugar to prevent further deterioration of the condition. If you are pregnant again with diabetes, you should be treated under the guidance of a specialist. The effect of gestational diabetes on mother and child depends on the condition of diabetes and the level of blood glucose control, and the more severe condition or poor blood glucose control will affect mother and child greatly. If the condition is severe or poorly controlled, it will have a great impact on the mother and child. You should control your diet reasonably, eat less food with high sugar content, and take insulin therapy if necessary.
