High resistance to blood flow in the uterine arteries. First, the most common cause is due to arterial thrombosis, which is mainly seen in patients with hypertension, hyperglycemia, hyperlipidemia, and those suffering from varicose veins in the lower extremities and atrial fibrillation. Secondly, local stenosis or pressure stenosis caused by external pressure due to arterial lesions can be relieved by releasing the pressure. Further improvement of enhanced CT, MRI or arteriography is possible, and the treatment needs to be determined according to the specific condition, and interventional treatment is needed if necessary. You should pay attention to a light diet, avoid eating too much greasy and indigestible food, control your blood pressure, blood lipids and blood sugar, exercise properly, control your weight, eat a reasonable diet, quit smoking and drinking, and avoid standing or sitting for a long time to avoid varicose veins.
