Patient's question:
My daughter is five years old. Recently, I noticed small hard lumps on her chest. I want to ask the doctor if this could be precocious puberty? The child has low immunity around the age of four. Following the advice of the clinic doctor, she has been taking L-lysine B12 intermittently for nearly a year. Could a doctor provide a judgment?Doctor's answer:
Lysine is one of the essential amino acids for the human body. It promotes human growth and development. Even if you consume lysine for a long time, it will not cause precocious puberty. Lysine does not contain hormones and will not cause hormonal imbalance in the body. The causes of precocious puberty are diverse. The most common one is the decreased sensitivity of the hypothalamus to gonadotropin feedback. This can lead to the premature secretion of gonadotropin-releasing hormone. Of course, it also includes some tumors in the brain, reproductive organs, and adrenal glands. Some tumors are caused by exogenous hormones.
