What\’s the reason for the black line in the middle of pregnant woman\’s belly?

Why is there a black line in the middle of a pregnant woman\’s belly? A black line in the middle of a pregnant woman\’s belly, also called a pregnancy line, is a physiological change that occurs during pregnancy. This linea nigra runs from the belly button to the pubic bone, and in some pregnant women, the linea nigra extends to the chest. The appearance of pregnancy lines is due to the increased secretion of hormones in pregnant women, which leads to pigmentation and dilation of blood vessels, which deepens the color of the abdominal skin and forms a black line. The time when pregnancy lines appear varies from person to person, but most pregnant women begin to appear around the fourth month of pregnancy. The length and width of pregnancy lines also vary from person to person. Some pregnant women have only a thin line, while others have a wide black line. During pregnancy, the color of the pregnancy line will also change with the different stages of pregnancy, from light to dark, until it reaches its darkest late in pregnancy. 200 Examples of Nutritional Recipes for Pregnant Women in Three Months Ultra-clear Full Color PDF The appearance of pregnancy lines is related to the physique of pregnant women.
