Why do nipples turn black during pregnancy

Darkening of nipples during pregnancy is a normal physiological phenomenon caused by changes in hormone levels. After pregnancy, the levels of estrogen and progesterone in women's bodies increase significantly. These hormones stimulate the secretion of melanocytes, causing the nipples to darken.

During pregnancy, the hormone levels in pregnant women change significantly, especially the increase in estrogen and progesterone. Both hormones are important factors in promoting the secretion of melanocytes. Therefore, pigmentation may appear on the nipples, areolas and other parts of pregnant women, resulting in darkening. In addition to changes in hormone levels, there are other factors that may also cause nipples to darken after pregnancy, such as prolonged exposure to the sun, friction from clothing, and lack of vitamin C and vitamin E. Although the impact of these factors is relatively small, pregnant women still need to pay attention.

Although it is normal for nipples to darken after pregnancy, pregnant women can still take some measures to prevent and alleviate it. For example, maintain a reasonable diet and consume adequate vitamin C and vitamin E; keep breasts clean and hygienic and avoid using irritating lotions; and maintain a happy mood and avoid excessive anxiety and stress.
