SIXTH MONTH: "ENLARGING VEINS ON THE LEGS, VULVA, RECTUM, NECK (or ANYWHERE!)
Varicose veins are just another of the many side effects of being pregnant. The hormones of pregnancy relax the muscular walls of veins, causing them to enlarge. These vessels need to expand to accommodate the extra blood volume of pregnancy. Legs are particularly likely to host varicose veins because the expanding uterus presses on the major blood vessels beneath it, and this puts pressure on the veins of the pelvis, sometimes causing blood to pool in the legs. Hemorrhoids are a type of enlarged vein, and you may notice bulging veins along your vulva. Whether or not you develop varicose veins during pregnancy is mostly a matter of heredity. If you notice that an area around the visible veins of your lower leg has become increasingly painful, red, swollen, warm, or tender, a vein may have become infected; a condition called thrombophlebitis, which is very serious; elevate your leg and notify your healthcare provider.
4 Ways to Reduce the Appearance of Varicose Veins
1. Avoid standing or sitting for long periods of time. Don't cross your legs while sitting. If you must be stationary, promote circulation by doing leg and foot exercises and walking around periodically to encourage circulation in your legs.
2. Elevate your feet as high as possible when you sit. Lie and sleep on your left side.
3. Wear loose clothing. Avoid tight pants, waistbands, garters and socks, and any other clothing that may restrict circulation.
4. Wear support hose. Put them on even before you get out of bed in the morning, before gravity gives your veins a chance to pop out. Avoid calf- length support stockings since the band at the top may constrict blood return. "
