What is the normal development of girls' breasts?

As parents, we are very concerned about girls in puberty. The normal development of girls' breasts is a concern for many female parents. Some girls start to develop before they are ten years old, which makes many parents very worried. In fact, knowing more medical knowledge in daily life can be very helpful to people's daily life. So what is the normal development of girls' breasts like? Let’s find out together.

1. What is considered normal development?

Due to the improved living conditions in modern times, children absorb sufficient nutrition and start to develop earlier than before. When girls reach the age of 9 to 10, their breasts begin to develop, the amount of breast tissue increases, and the appearance of the breasts also increases. After 4 to 5 years of development, that is, by around the age of 15, the breasts have taken shape, become fuller, and the nipples have enlarged, thus showing the unique curves of women.

2. Developmental process

Development process: The first stage (1 to 9 years old): Before puberty, breasts have not yet developed. The second stage (10-11 years old): In the early stage of breast development, the breast bud under the nipple begins to grow and appears as a distinct dome-shaped bulge. Stage 3 (12-13 years old): The breasts become round and shaped like adults, but are still small. Stage 4 (14-15 years old): The breasts enlarge rapidly, and the nipples and areola protrude forward, shaped like small balls. If you are still the same as when you were 13, you need to find out the reason. Stage 5 (16-18 years old): Normal adult breasts are formed, and the small balls of the nipple and areola merge into the round shape of the breast. Breast development is affected by factors such as region and race, and the time when women's breasts begin to develop varies. For most women, breast development begins between the ages of 8 and 13, and fully matures between the ages of 14 and 18. Breast development usually starts from the left side, and it takes about 3-5 years from the beginning of development to full maturity.

3. Differences in breast development between men and women

There is great individual variation in breast development in girls. Some girls begin to develop breasts when they are only 8 or 9 years old, while some girls do not begin to develop breasts until they are 16 years old or older. Most girls begin to develop breasts before their first menstrual period, around 9 to 14 years old. I hope my answer can help you and I wish your child good health. Before puberty, there is no difference in appearance between boys' and girls' breasts. Starting from the age of 7-8, girls' body systems gradually develop. About 2 years later, breasts begin to develop under the combined action of ovarian hormones, pituitary hormones and insulin. The age of breast development also varies from person to person, with an average of 10.8-11.4 years old. If breasts have not developed after the age of 16, you should be alert to whether it is delayed sexual development or ovarian hypoplasia.

4. Causes that affect development

Factors affecting breast development: poor spleen and stomach. The relationship between the spleen, stomach and chest is manifested in two aspects. First, the spleen and stomach are the foundation of acquired constitution, which are responsible for digestion and absorption. If there is acquired malnutrition, it is inevitable that breast development will be affected. Therefore, blindly losing weight can cause menstrual disorders and breast shrinkage because the fat in the breasts is absorbed into other places where fat is needed. Therefore, the result of blindly losing weight is usually that the places you want to lose weight do not get thinner, and the places you don't want to lose weight become deflated. Second, the spleen controls the muscles of the human body. If the spleen and stomach are not healthy, the muscles will be weak. Therefore, if the spleen and stomach are not well taken care of, the breasts will easily sag. It can be seen that breast development has a great relationship with a healthy spleen and stomach.

After reading the above summary I made about the normal development of girls' breasts, I believe it has solved many questions for many parents. As parents, it is important to understand some basic medical knowledge, which is very important in family life. While caring about the growth of children, dietary nutrition is of paramount importance. Only when you care for your children in all aspects can they grow up healthily and happily.
