Whether or not a girl can grow as an adult depends on whether or not her epiphyses are closed; if they are not, she may still grow.
Some girls’ epiphyses are not completely closed when they have an epiphyseal examination at the age of majority (usually 18 years old), and they may still continue to grow in height at this time. The growth and development of girls is not only related to hereditary factors, but also to environmental factors, dietary factors and other factors.
If the epiphyses are found to be completely closed during the epiphyseal examination, it means that the growth has stopped and basically there will be no more growth in the later stages.
You should pay attention to your diet, do not eat too spicy and stimulating food, you can eat food containing more calcium, such as eggs, milk and so on. Adequate sleep and outdoor activities will also help adolescent girls grow taller.
