Growth issues


Hello, Dr.
Yeh.
I read online that after the age of 14, only height will continue to grow, and that leg length is mostly determined before the age of 14.
Is this true or false? I am quite concerned about my body proportions.
My current bone age is over 14 years, and my father is 165 cm and my mother is 160 cm.
I am receiving growth hormone treatment.
Can you provide me with a specific number for the best time to sleep? I really want to grow taller.

Hello! The secretion of growth hormone typically occurs between 10 PM and 3 AM, with pulses every 60 to 90 minutes during deep sleep.
Therefore, the duration and quality of sleep are very important.
It is recommended to turn off the lights and go to sleep before 10 PM.
Additionally, regular exercise is also quite important!

Hello! Thank you for your question regarding growth issues, height development, and hormone therapy. It's understandable to be concerned about height, especially during your teenage years when growth and body proportions can significantly impact self-esteem and social interactions.
To address your first point, the idea that leg length is primarily determined before the age of 14 is somewhat misleading. While it is true that most growth in height occurs during puberty, which typically starts around ages 10 to 14 for girls and 12 to 16 for boys, growth plates in the bones can remain open for a few years after this age. Growth plates are areas of developing cartilage tissue near the ends of long bones, and they close after puberty, which means that height growth can continue until these plates fuse.
In your case, since your bone age is already at 14 years, it suggests that your growth plates may be nearing closure. However, this does not mean that you cannot grow taller; it simply indicates that your growth potential may be limited. Factors such as genetics, nutrition, and overall health play crucial roles in determining your final height. Given that your parents are of average height (father 165 cm and mother 160 cm), your genetic potential may also be a contributing factor.

Regarding growth hormone therapy, it is essential to understand that this treatment is typically reserved for individuals who have a diagnosed growth hormone deficiency or specific medical conditions that hinder growth. If you are currently receiving growth hormone therapy, it is crucial to follow your healthcare provider's recommendations and monitor your progress regularly.
As for sleep, it is widely recognized that adequate rest is vital for growth and development, especially during adolescence. The recommended amount of sleep for teenagers is generally between 8 to 10 hours per night. Sleep is when the body releases growth hormone, so ensuring you get enough quality sleep can positively impact your growth potential. Aim to establish a consistent sleep schedule, going to bed and waking up at the same time each day, and create a restful environment to promote better sleep quality.

In addition to sleep, maintaining a balanced diet rich in essential nutrients is crucial for growth. Ensure you are consuming enough protein, calcium, vitamins, and minerals to support your body's needs. Engaging in regular physical activity, particularly exercises that promote stretching and flexibility, can also be beneficial. Activities such as swimming, basketball, or yoga can help improve posture and may contribute to a taller appearance.

Lastly, it is essential to have open communication with your healthcare provider regarding your growth concerns. They can provide personalized advice based on your specific situation, including whether continued growth hormone therapy is appropriate and what other lifestyle changes you can make to support your growth.

In summary, while there are genetic and biological factors that influence height, there are also lifestyle choices you can make to optimize your growth potential. Focus on getting enough sleep, maintaining a healthy diet, and staying active. Remember that height is just one aspect of who you are, and developing your skills, interests, and personality is equally important.
