Patient's question:
Sure, I can help with that. However, you haven't provided any content to translate. Please provide the text you want to be translated into English.Doctor's answer:
Adolescent girls may have immature ovarian function, which is highly unstable. Additionally, their emotions are prone to fluctuations, and factors such as academic or work stress, high levels of physical activity, changes in environment and climate, and nutritional imbalances can all affect the regulation of ovarian hormones, leading to menstrual disorders. In the first few years after menarche, the menstrual cycle interval can be as long as two or three months, which is normal.
