Height growth issues


Height concerns – Hello Doctor: A 13-year-old girl in the first year of junior high school has a bone age of 13 years, measuring 150.8 cm and weighing 44 kg (menstruation has started for 1 year, father is 172 cm, mother is 161 cm).
I would like to ask: 1.
Will she continue to grow taller? How much more can she grow? 2.
Is it still possible to take growth-promoting supplements? 3.
Is it normal to have only grown 1 cm in the past 4 months, or is this a sign that she has stopped growing? Thank you for your hard work!

Mimi, 10~19 year old female. Ask Date: 2021/01/22

Dr. Pei Rensheng reply Pediatrics


Hello: According to genetics, the expected adult height is calculated as the average of the parents' heights minus 6.
Therefore, (172 + 161) / 2 = 166.5, and 166.5 - 6 = 160.5 cm.
However, the current height is 150.8 cm, and the bone age is already 13 years, which corresponds to the actual age, and menstruation has occurred for a year, indicating that there is limited growth potential.
Additionally, after puberty, height typically increases by less than 5 cm per year, so significant height advancement should not be expected.
Engaging in more physical activity, ensuring proper nutrition, and paying attention to the critical sleep period from 11 PM to 3 AM when growth hormone secretion peaks may still provide some growth opportunity.
Wishing you health, happiness, and peace! Sincerely, Ren Sheng.

Height growth during adolescence is a common concern for many young individuals and their families. As you are currently in the early stages of puberty, it is important to understand how growth patterns work and what factors can influence your height. Let's address your questions one by one.

1. Will you continue to grow taller? How much more height can you expect?
At the age of 13, especially for girls, you are likely still in the growth phase. The average age for girls to reach their peak height velocity (the fastest rate of growth) is around 11 to 12 years old, but growth can continue until the late teens. Given that you have already started menstruating (as indicated by your mention of having had your first period), you are likely past the peak growth spurt, but you can still grow taller. The amount you can grow depends on several factors, including your genetic potential (which can be estimated based on your parents' heights), nutrition, and overall health. Since your father is 172 cm and your mother is 161 cm, you may have the potential to reach a height in the range of 160-170 cm, but this is not guaranteed.

2. Is it too late to take growth supplements?
The term "轉骨方" (growth supplements) often refers to traditional remedies or supplements that claim to promote growth. While some supplements may contain vitamins and minerals that support overall health, there is no scientific evidence to suggest that they can significantly increase height once the growth plates begin to close. It is essential to focus on a balanced diet rich in calcium, vitamin D, protein, and other nutrients that support bone health. Engaging in regular physical activity, particularly weight-bearing exercises, can also promote healthy bone development.

3. Is it normal to have only grown 1 cm in the last four months?
Growth rates can vary significantly among individuals, especially during puberty. It is not uncommon for growth to slow down after the initial spurt. A growth of 1 cm over four months may be within the normal range, especially if you are still experiencing some growth. However, if you notice a significant decrease in growth over an extended period, it may be worth consulting a healthcare professional to rule out any underlying health issues.

In summary, while you are likely still capable of growing taller, the rate of growth may slow down as you approach the end of your growth phase. It is essential to maintain a healthy lifestyle, including a balanced diet and regular exercise, to support your growth potential. If you have ongoing concerns about your height or growth patterns, consider discussing them with a healthcare provider who can provide personalized guidance based on your specific situation. Remember, every individual grows at their own pace, and it is essential to focus on overall health and well-being rather than just height.
