The function of the physiological changes during pregnancy is to prepare the body for the condition of becoming a mother. Some of them are the increase in the blood flow and the changes on the breasts tissues. Breasts are of vital importance during the first months of the baby once he’s born.
Below you have an index with the 4 points we are going to deal with in this article.
Estrogenic and luteal hormone
During gravidity there’s an increase in the levels of estrogenic and luteal hormone that stimulate the gland development. Breasts tend to get more rounded due to the development of adipose tissue that can be found within them.
Breast sensitivity is one of the first symptoms of pregnancy and it usually begins between the fourth and sixth week of pregnancy and it lasts up to three months after the baby is born.
Sebaceous glands in the nipple
During the first months breasts become ample and their size increases. Aureole and nipple’s skin pigmentation increases considerably and some small bulges may appear, named Morgagni’s tubercles, due to the development of the sebaceous glands.
The blood irrigation in the breasts increases and the superficial veins are visible. This effect could even increase during breastfeeding.
Colostrum before delivery
During the third month of pregnancy, breasts produce a substance named colostrum, a special milk that will provide the baby with protection against infections during the first days of life.
During the breastfeeding period the changes that happened during pregnancy tend to continue. At the beginning of the breastfeeding period and during the first hours, the continuous sucking attempts of the baby provoke the expulsion of the colostrum, which is yellowish, dense and has a lot of cholesterol.
The choice of the bra is of vital importance during this period: it has to be soft, better if it’s made of cotton, and it has to provide good fastening. A good choice would be buying a breastfeeding bra, for you would use it to feed the baby. When buying bras, it must be taken into account, the fact that breasts will continuously increase their size during pregnancy.
Properties of the colostrum
As we stated before, the colostrum is rich with cholesterol, dense and yellowish. It is a special milk that contains lots of amino acids and plays a vital role in the growth and development of the baby. The colostrum also contains antibodies, which are in charge of preventing the infections.
Proteins, vitamins and cytokines are other properties of the colostrum that will be beneficial for the baby during his first months of life. Glycoproteins make it possible for growth and immune factors to traverse the digestive tract, preventing them from being digested.
