Hypoglycemia is a relatively common clinical phenomenon in pregnant women during pregnancy, mainly manifesting as dizziness, blurred vision, and even fainting. This occurs because the metabolism of pregnant women accelerates during pregnancy, while the secretion of the islets is not correspondingly increased. This results in the physiological function of the islets being very active, which can easily lead to low blood sugar in expectant mothers, causing symptoms such as dizziness and fatigue due to hypoglycemia. Additionally, hormonal changes during pregnancy can lead to decreased appetite, nausea, vomiting, irregular eating habits, and malnutrition in pregnant women. Despite this, energy consumption still occurs, which can also lead to hypoglycemia.
