Can My Sister Still Grow Taller? Height Concerns in Adolescents - Orthopedics

Short stature?


Hello, doctor.
I have a younger sister who is in the second year of junior high school.
She is 151 cm tall and weighs between 43 to 44 kg.
She hasn't grown taller for a while, and she started her menstrual period after the winter break in fifth grade.
Her father is 185 cm, her mother is 166 cm, and her brother is 184 cm.
She enjoys sports, but she feels very short and is quite self-conscious about it.
Is there still a chance for her to grow taller?

Hello: There is a possibility of growth, but it is not possible to predict how much taller she will grow.
If you are concerned about her height, please take her to a pediatric endocrinology and metabolism specialist for further evaluation.

Hello! It's great that you're looking out for your sister's health and well-being. Height growth during adolescence can be a significant concern for many young people, especially when they feel self-conscious about their stature compared to their peers or family members.
At the age of 14, your sister is still within the typical range for growth spurts associated with puberty. Generally, girls experience their most significant growth spurts between ages 10 and 14, with most of their height growth occurring before their first menstrual period. Since your sister started menstruating in the fifth grade, she may have already gone through a significant portion of her growth phase, but that doesn't mean she has stopped growing entirely.

Genetics plays a crucial role in determining height. Given that both her parents and brother are tall, she has a genetic predisposition to be taller as well. However, it's essential to understand that growth patterns can vary significantly among individuals. Some adolescents may experience late growth spurts, which can occur as late as 16 or even 18 years of age in some cases.
In terms of her current height of 151 cm (approximately 4 feet 11 inches), it's important to consider her growth history and overall health. If she has not grown in height for a while, it might be beneficial to consult a healthcare professional, such as a pediatrician or an endocrinologist, who specializes in growth and development. They can assess her growth plates through X-rays to determine if she still has potential for growth.
Nutrition and physical activity also play vital roles in growth. Since your sister enjoys sports, that’s a positive factor. Regular exercise can promote healthy growth and development. Additionally, a balanced diet rich in essential nutrients—especially calcium, vitamin D, and protein—is crucial for bone health and growth. Encourage her to consume a variety of foods, including fruits, vegetables, whole grains, lean proteins, and dairy products.

Emotional support is equally important. If your sister feels self-conscious about her height, it’s essential to reassure her that everyone grows at their own pace and that height does not define her worth or abilities. Encourage her to focus on her strengths and interests, and remind her that confidence and self-esteem come from within.

In summary, while your sister may have some concerns about her height, there is still a possibility for her to grow taller, especially considering her family background. Consulting with a healthcare professional can provide clarity on her growth potential. In the meantime, supporting her emotionally and encouraging healthy habits will be beneficial for her overall well-being.

Dr. Wang Shouji reply Orthopedics
Xiaolin: Height is related to multiple factors, and theoretically, the chances of growing taller after the growth plates close are minimal. Just because others can, it doesn't mean you necessarily can (the timing of growth plate closure may vary for each individual).
