The early onset of menstruation in children may affect their height. The age of first menstruation for women is generally between 13 and 14 years old, as early as 11 years old and as late as 16 years old. With the change of modern nutritional structure, the age of first menstruation has a tendency to advance gradually and. Currently, the onset of menstruation before the age of 10 is called precocious puberty in females. Under the influence of hormones in the body, height growth accelerates prematurely and the epiphysis heals in advance, which ultimately affects the height in adulthood, and the age of the first menstruation is affected by a variety of factors such as genetics and nutritional factors. In order to prevent precocious puberty, we should reduce or avoid long-term exposure to plastic products, disposable lunch boxes and other chemicals, while improving dietary structure, avoiding high-calorie, deep-fried, puffed food, balanced nutrition, while increasing physical exercise and reducing exposure to electronic products. If the onset of menstruation occurs earlier than the age of 10, you should consult a hospital in a timely manner and use medication under the guidance of a doctor to minimize the impact on your child’s future height.
