Patient's question:
My daughter is five years old. Recently, she has developed small hard lumps on her chest. I want to ask the doctor if this could be precocious puberty. She has been drinking lysine B12 intermittently for nearly a year, following the advice of the clinic doctor because she had low immunity around the age of four. Could a doctor provide a judgment on this?Doctor's answer:
Lysine is one of the essential amino acids for the human body, but it has the function of promoting human growth and development in terms of level and arrangement. 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 varied, the most common of which is the decreased sensitivity of the hypothalamus to gonadotropin feedback, which leads to the premature secretion of gonadotropin-releasing hormone. Of course, it also includes some tumors in the brain that affect reproductive organs and adrenal glands. Some tumors are caused by exogenous hormones.
