Among the problems that women face every day, expectant mother, it should be noted fatigue, discomfort, heaviness, tension in the legs, tingling and cramps in the calf muscles at night, the visible swelling of the feet and varicose veins, which is or appears for the first time, or increases in early stages of pregnancy. These complaints are particularly frequent if: • Diseases of veins were observed in close relatives • varicose veins were before pregnancy • Pregnancy is not the first • a pregnant woman has a lot of sitting or standing - for example, at work • pregnant leads a sedentary life and do not do sport Typically, the hottest time of year, all of these symptoms are magnified. These disorders not only impair the health of pregnant and are cosmetic defects, but also are major risk factors for development of inflammation of varicose veins (thrombophlebitis), as well as circulatory disorders that can cause serious problems for the mother and her child. That is why it is necessary to take effective measures to prevent such problems or reducing them to a minimum, if they already exist. Well it can be done if we understand why varicose veins or other problems with his feet so often occur during pregnancy. Having varicose veins and swollen legs, of course, very unpleasant and uncomfortable, increasing at night, is an additional factor for sleep disorders, which often suffer from pregnant women. Varicose veins are not only ugly, but, as noted above, they can get inflamed or lead to the development of thrombosis. Until now, little attention was paid to the negative influence of circulatory disorders in the mother's state of the fetus and the occurrence of various complications during pregnancy. At later stages of pregnancy during the transition from a sitting position (lying down) in the standing position, the woman increases the heart rate much more visible than before pregnancy. Mother's body tries to compensate for the reduction of blood supply of the heart and reduced cardiac output, developing due to stagnation of blood in the veins of the legs. That is why, in an upright position in a pregnant woman has been a significant increase in heart rate needed to maintain constant blood pressure and prevent fainting. With a significant reduction of blood filling the hearts of even the maximum possible increase in heart rate is insufficient to maintain a high cardiac output. The inevitable consequence - reducing blood supply to many organs, including cancer. In such cases, if the pregnant woman is in an upright position, the record fetal cardiac activity indicates a stressful situation for him. Moreover, it was completely new and interesting observation: from time to time (after about 1-2 minutes) heart rate of pregnant, located in a standing position, and returns to normal, and this coincides with uterine contraction. It is believed that through muscular contractions uterus overcomes spasm of vessels and increases venous return. With sufficient blood filling the heart no longer needs the frequent cuts - the result can clearly see if you make a schedule. What is the cause of increasing contractility of the uterus, and what is the mechanism of this phenomenon is not entirely clear, since the cause and mechanism of this phenomenon not completely understood.
