What should I do at 19 years old if I basically have no chest?

In general, the lack of breast development at age 19 may be caused by factors such as genetics, malnutrition, or lack of exercise. This can be improved by increasing intake of protein-rich foods such as eggs, pig trotters, and chicken feet, or through appropriate physical activities like running, jumping rope, and yoga. Alternatively, one may consider procedures such as autologous fat transfer or implant-based augmentation for improvement.

The above procedures should be performed at正规 medical institutions under the guidance of qualified physicians. After surgery, proper wound care is essential—keep the area clean, maintain a light diet, and avoid infection.
