Increased blood flow in the uterine arteries may be caused by sclerosis of the uterine arteries, more commonly due to hypertension during pregnancy or changes in the small blood vessels caused by gestational diabetes, which increases the local pressure and leads to increased arterial blood flow. Therefore, it is necessary to control blood pressure and blood glucose, pay attention to a reasonable and light diet, eat less greasy and indigestible food, and avoid excessive intake of food with high sugar content. Increased blood flow in uterine artery is also common in uterine tumor, because local tumor requires abundant blood supply, which will lead to increased blood flow and thus increased blood flow in uterine artery. It is important to pay attention to any physical symptoms, especially during pregnancy, to monitor blood glucose and blood pressure regularly to avoid accidents, because atherosclerosis can lead to fetal hypoxia.
