I have a problem with not growing taller?


Hello, I am a second-year junior high school student.
I am currently 164 cm tall, but I entered puberty in the 5th or 6th grade of elementary school, and I have noticeably felt that my growth in height has slowed down (I have only grown 1.2 cm this year).
My father is 158 cm tall, and my mother is 157 cm tall.
Could this be due to genetic factors? If so, are there any methods that can help me grow taller? Thank you for taking the time to respond to my question.

Based on your current height, it appears to be within the normal range, so there is no need to worry too much at this time.
To assist with growth, focus on a balanced diet and engage in regular moderate exercise, as these should be beneficial.
As for medication, there is currently no need for it.

Height is a complex trait influenced by a combination of genetic and environmental factors. In your case, given that both of your parents are on the shorter side, it is likely that genetics plays a significant role in your height potential. The average height of parents can often provide a rough estimate of the height their children might achieve, but it is important to remember that individual growth patterns can vary widely.

During puberty, which typically occurs between ages 10 and 14 for girls and 12 and 16 for boys, the body experiences a surge in growth hormone, leading to rapid height increases. However, the growth plates in the bones, known as epiphyseal plates, eventually close after puberty, marking the end of vertical growth. For most individuals, this closure occurs by the late teens to early twenties. Since you are currently in the early stages of your teenage years, you may still have some growth potential left, but it might be limited due to your genetic background.

In terms of methods to potentially enhance your growth, here are some scientifically supported strategies:
1. Nutrition: A well-balanced diet rich in essential nutrients is crucial for growth. Ensure you are consuming adequate amounts of protein, calcium, vitamin D, and other vitamins and minerals. Foods like dairy products, lean meats, fish, fruits, vegetables, and whole grains can support your growth.

2. Physical Activity: Regular exercise, particularly activities that promote stretching and strengthening, can be beneficial. Sports like basketball, swimming, and even yoga can help improve posture and flexibility, which may give the appearance of being taller.

3. Sleep: Growth hormone is primarily secreted during deep sleep. Therefore, ensuring you get enough quality sleep each night is vital for growth. Aim for 8-10 hours of sleep per night, especially during your teenage years.

4. Posture: Maintaining good posture can help you maximize your height. Slouching can compress your spine and make you appear shorter than you are. Focus on standing and sitting up straight.

5. Avoid Growth Inhibitors: Certain lifestyle choices can negatively impact growth. Avoid smoking, excessive alcohol consumption, and drugs, as these can interfere with your body's natural growth processes.

6. Consult a Healthcare Professional: If you have concerns about your growth or if you feel that your growth is significantly delayed, it may be worth consulting with a healthcare provider. They can evaluate your growth patterns, possibly conduct tests like X-rays to assess your growth plates, and provide personalized advice.

While it is natural to feel concerned about height, it is essential to focus on overall health and well-being rather than just the number on a measuring tape. Remember that height does not define your worth or capabilities. Embrace your unique qualities and focus on developing your skills and interests.
In conclusion, while genetics plays a significant role in determining height, there are several lifestyle factors you can control that may help you reach your maximum potential. Stay positive, focus on your health, and remember that everyone grows at their own pace.
