The onset of gestational diabetes is primarily due to uncontrolled diet during pregnancy, leading to rapid weight gain, which in turn causes insulin resistance and results in high blood sugar. Gestational diabetes is characterized by increased blood sugar levels caused by this insulin resistance. In the early stages, it can be managed by controlling diet and increasing physical activity to keep blood sugar within a reasonable range. If blood sugar cannot be controlled, insulin medication intervention may be necessary. How to prevent it in the early stages? Mainly, it involves keeping weight within a reasonable range, monitoring weight gain, while ensuring normal fetal development. Additionally, in terms of diet, avoid excessive intake of foods high in oil, such as animal organs; fats and oils are high in lipids, which can also exacerbate insulin resistance, leading to the development of gestational diabetes. (Please use medication under the guidance of a doctor to avoid blind self-medication).
