2. Five reasons why breasts are too big and small
1.Mental cycle hormone fluctuations
Estrogen and progesterone levels change at different stages of the menstrual cycle. Before and after the ovulation period, estrogen increases will cause congestion in breast tissue, and the chest may increase by 1-2 cups; and after menstruation, hormone levels drop and the chest will return to its original state.
2.Weight fluctuations
The breasts are mainly composed of fat and breast tissue. When you gain weight, fat accumulation may make your breasts fuller; conversely, after losing weight, your breasts may "shrink". Data shows that for every 5 kg of weight gain, the bust circumference may change by 1-3 cm.
3.Sports and underwear options
High-intensity exercise (such as running) may cause chest ligaments to stretch and temporarily sag; wearing inappropriate underwear (such as not wearing sports underwear for a long time) may also affect breast shape. It is recommended to choose supporting underwear to reduce fluctuations.
4.Pregnancy and breastfeeding
During pregnancy, the secretion of estrogen and prolactin increases, and breast development will lead to significant enlargement of the chest; after the lactation period, the chest may shrink due to fat loss, or even relax.
5.Disease or drug effects
Diseases such as polycystic ovary syndrome (PCOS) may cause hormone disorders and cause abnormal swelling of the chest; certain birth control pills or hormone drugs can also affect the size of the chest.
