Hair on the belly during pregnancy is a common phenomenon during pregnancy, mainly due to the rise in the level of hormones in the body, and can not explain what the problem is, and generally will not affect the development of the fetus. If a pregnant woman has a hairy belly, it is mainly due to the change of hormone levels in the pregnant woman’s body after pregnancy. Androgen secretion increases, while melanin secretion also increases, which can lead to pigmentation and hairiness. Hair growth during pregnancy usually does not affect the growth and development of the fetus, the time of hair growth, usually around 8 weeks of pregnancy. After giving birth to a baby, the hormone level of the pregnant woman’s body decreases, the vast majority of which can be restored to the pre-pregnancy state, so it does not indicate any problem. Clinically, if a pregnant woman has hair on her stomach, don’t worry too much, but if it is accompanied by abdominal pain and other uncomfortable symptoms, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor to improve the relevant examination, to clarify the cause and symptomatic treatment.
