Although your obstetrician probably recommends that you exercise on a daily basis for other reasons, daily exercise will also help your circulation in your lower extremities and decrease the risk that you will develop varicose veins.
The development of spider veins and varicose veins is often a result of extra stress placed upon the venous system. This can happen when an individual sits or stands for any length of time, or add extra weight. Just the act of becoming pregnant and growing a baby for nine months, means that you have added an extra 20 to 30 pounds over the course of your pregnancy. Work hard to keep your weight within the recommended range for your stage of pregnancy and do not view this time as nine months of eating poor nutritional choices and gaining more weight than your physician recommends.
