Many girls will find a brown line on their stomach when they take a bath, and many people will feel confused and worried because of this. What exactly is this line?What are the effects on our bodies?In this article, Gu Fang Yiyuan will answer these questions for you. 
1. Formation of the midline of the abdomen.
The midline of the abdomen, also known as the line alba, is a line located in the middle of the abdomen. The formation of this line is related to our genetics and hormone levels. During embryonic development, both males and females have a dark line, the ventral linea.
With the secretion of sex hormones, the white line of the abdomen will become darker in men and gradually lighter in women until it becomes the brown or white line we see.
Second, the role of the midline of the abdomen.
The midline of the abdomen has a certain physiological role in the human body. First of all, it is the junction of the abdominal muscles that helps protect the organs within the abdominal cavity. Secondly, the line alba can be used as a marking line during surgery, which helps the doctor determine the location of the surgical incision at the time of surgery. In addition, the line alba can also be used as an observation indicator during prenatal care for pregnant women, which can help to assess the development of the fetus.
3. Changes in the midline of the abdomen.
While the midline of the abdomen is part of the body's normal physiological structure, its color and shade can vary depending on individual differences. Some people may have a shallow midline of the abdomen, while others may have a deeper midline. In addition, the midline of the abdomen may become more pronounced in women during pregnancy. These changes are normal physiological phenomena and should not be overly worried.
Gu Fang Yiyuan's tip: The midline of the abdomen is part of the normal physiological structure of the human body, and many women pay attention to it. If you have doubts or concerns about your midline of the abdomen, it is advisable to consult a medical professional for answers.
