Breast ptosis generally refers to sagging of the breasts. Sagging breasts at a young age are considered to be related to weight loss, medication, and breast hypertrophy. 1. Weight loss: If a young child has recently lost weight, it can lead to a decrease in breast fat tissue and skin laxity, thus manifesting as breast ptosis. 2. Medication: For those who have recently taken penicillamine, cyclosporine, estradiol, progesterone and other medications, the medications can lead to breast enlargement, which in turn manifests itself as breast ptosis. 3. Breast hypertrophy: the disease is mainly considered to be related to hormonal disorders that cause abnormal breast development, and patients show excessive increase in breast size. If a young person suffers from breast hypertrophy, breast ptosis may occur. In young patients who have been screened for breast lesions, the symptoms can usually be improved by suspending the sagging breasts and fixing them in a normal position on the chest wall. For those with severe breast ptosis, surgical procedures such as breast reduction, breast lift, and breast augmentation are also available. It is recommended that people with sagging breasts choose the appropriate treatment measures according to their actual situation. They should pay attention to the rationality of their diet, avoid excessive weight gain, and pay attention to the proper sitting and standing posture, avoiding hunching over the chest.
