Can I Still Grow Taller? Growth Potential at 15

Is there a chance of having a normal height?

Since the first year of junior high school, my height was 155 cm, then 161 cm in the second year, and three months ago I measured 166 cm in the third year.
It seems I have grown about 5.6 cm in a year, while my classmates have grown 7.8 cm, and I am gradually being surpassed.
I am almost 15 years old and my height is close to 168 cm.
I am not dissatisfied, but I am a bit worried as I see the average height in Taiwan increasing.
My father is 172 cm and my mother is 160 cm, and I at least want to be taller than my father, around 173 cm.
A few weeks ago, I had a growth plate X-ray, and there is still a little space left in my feet, but a lot in my hands.
What does this mean? Does having any part not fully grown indicate that there is still a chance to grow taller? In the third year, I was 166 cm and weighed 75 kg.
I have lost weight but still eat the same amount.
I have increased my exercise significantly and have slimmed down to 68 kg, with a BMI that is almost acceptable.
Doctor, should I continue this approach of eating more and exercising more for weight loss? Will it have a negative impact on my growth? Thank you for your response, doctor.

Maintaining regular exercise is sufficient; excessive exercise can be harmful.

More Info

At the age of 15, many individuals are still within their growth phase, and there is a possibility for further height increase, depending on several factors. Your current height of 168 cm, combined with your family history (father at 172 cm and mother at 160 cm), suggests that you may have the genetic potential to grow taller. However, the growth potential is influenced by various factors, including nutrition, physical activity, sleep patterns, and the status of your growth plates.

From your description, it seems that you have experienced a steady increase in height over the past few years, which is a positive sign. The fact that you have recently had an X-ray of your growth plates and found that there is still some space for growth indicates that your growth plates have not yet fully closed. Growth plates, or epiphyseal plates, are areas of developing cartilage tissue near the ends of long bones. As long as these plates remain open, there is potential for further growth in height.

The presence of growth potential in one part of the body (like your feet) while other areas (like your hands) show more closure can be indicative of the natural variability in growth plate closure. Different bones in the body can close at different rates, and as long as there is still some open space in the growth plates, you may still have the opportunity to grow taller.

Regarding your weight loss and exercise regimen, it is essential to maintain a balanced approach. Engaging in regular physical activity is beneficial for overall health and can support growth by promoting better circulation and muscle development. However, it is crucial to ensure that you are not compromising your nutritional intake while trying to lose weight. A balanced diet rich in essential nutrients, including proteins, vitamins, and minerals, is vital for supporting growth and development during your teenage years.

Eating a well-rounded diet that includes adequate amounts of calcium (found in dairy products), vitamin D (which can be obtained from sunlight and certain foods), and protein (from sources like meat, beans, and nuts) is essential for bone health and growth. Additionally, maintaining a healthy sleep schedule is crucial, as growth hormone is primarily released during deep sleep.

In summary, at 15 years old, you still have the potential to grow taller, especially since your growth plates are not fully closed. Continue to focus on a balanced diet, regular exercise, and adequate sleep to support your growth. If you have concerns about your growth or weight management, consider consulting a healthcare professional or a nutritionist who can provide personalized guidance based on your specific needs and goals. Remember, growth patterns can vary significantly from person to person, and it's essential to focus on overall health rather than just height.
