Third trimester of pregnancy ( I )

• Hair changes. Pregnancy can cause changes in the texture and growth rate of hair. In many cases, pregnant women develop thicker hair during pregnancy. This is the result of hormones causing hair to grow faster and fall out less. Others notice that their hair changes color, or that it is drier or oilier than normal. In addition, some women grow hair in unwanted places, such as the face, abdomen and around the nipple. These changes usually disappear after delivery.

• Spider veins. The increased blood circulation during pregnancy can lead to the development of small reddish spots on the face, neck, upper chest or arms. These spots are commonly referred to as spider veins because they appear to sprout tiny blood vessels that resemble the legs of spiders. These marks, which are especially common among women with fair skin, usually fade or disappear after delivery.

• In addition, changes in hormone levels may slow the digestion process and relax the muscles that keep the stomach acids in the proper place. As a result, stomach acids reflux, causing a burning sensation in the throat and chest. Women may benefit from avoiding spicy, fried or fatty foods and eating smaller, more frequent meals. In addition, remaining upright for a period of time following a meal may decrease the heartburn and reflux. Women should contact their obstetrician–gynecologist (ObGyn) when they experience severe or persistent heartburn that does not respond to these treatments.

• Varicose veins. During pregnancy, pressure is placed on the large veins located behind the uterus. This slows the return of blood to the heart and puts pressure on the veins, causing them to swell. As a result, varicose veins may develop. These veins look swollen and cause pain. They may appear to be twisted, bulging and dark purple or blue in color. During pregnancy, varicose veins most often develop on the back of the calves, thighs and vagina. Women may benefit from avoiding long periods of standing, lying on their side and sitting with their legs and feet raised whenever possible.
