A friend asked me: I always want to lose weight, but I often hear that improper weight loss can affect pregnancy, so I would like to ask, can dieting and weight loss cause it? Many women pursue the so-called body beauty, blindly lose weight, but may not think that excessive slimness, it is likely to make them pay a heavy price – can not have children, because the wasting type of women have a higher chance of infertility than those with normal body type for. Studies have found that fat is important for the normal physiological development of women, and is especially important for women of childbearing age and pregnant women. The common gynecological manifestations include prolapsed uterus, retroflexion of the uterus, excessive leucorrhea, indifferent sexual desire, lack of sensuality, and scanty or amenorrheic menstruation, often accompanied by infertility or sterility.
