Can You Still Grow Taller After 40? Height Changes

Height increased by one centimeter?

At the age of eighteen, my height was 183 centimeters, but I continued to grow, and at the age of forty-two, I measured 186 centimeters.
Will I continue to grow taller? I'm concerned about being too tall.

Hello! After adulthood, the growth plates close, and height is less likely to change.
However, it is important to monitor for any enlargement of the extremities and a broadening of facial features.
If you have any concerns, please consult a specialist in metabolic disorders.

More Info

It is indeed unusual for someone to continue growing taller after the age of 40, as most individuals experience the closure of their growth plates during late adolescence or early adulthood. Typically, for males, growth plates close around the ages of 16 to 18, while females usually stop growing a bit earlier. Once these growth plates, also known as epiphyseal plates, fuse, further height increase is generally not possible through natural bone growth.

However, your experience of growing from 183 cm at 18 years old to 186 cm at 42 years old raises some interesting points. While it is uncommon, there are a few factors that could potentially explain this phenomenon:
1. Measurement Variability: Height measurements can vary due to factors such as posture, time of day, and the method of measurement. It’s possible that the increase you observed could be attributed to a more accurate measurement or a slight change in posture rather than actual bone growth.

2. Spinal Compression and Decompression: Throughout the day, the spine can compress due to gravity and other factors, leading to a slight decrease in height by the end of the day. Conversely, after a good night's sleep or after certain exercises, the spine can decompress, potentially leading to a temporary increase in height. This fluctuation can sometimes be mistaken for actual growth.

3. Hormonal Factors: Although rare, certain hormonal changes can lead to changes in body composition and even height. Conditions such as acromegaly, which is caused by excess growth hormone, can lead to increased height and changes in bone structure, but this typically occurs in younger individuals and is often accompanied by other noticeable symptoms.

4. Posture and Muscle Development: Engaging in activities that improve posture, such as yoga or certain forms of exercise, can lead to a more elongated appearance. Strengthening the core and back muscles can also improve posture, which may give the illusion of being taller.

5. Health and Nutrition: Maintaining a healthy lifestyle, including proper nutrition and regular exercise, can influence overall body composition and health. While this won't necessarily lead to an increase in height after growth plates have closed, it can affect how tall you appear.

If you are concerned about your height or any other changes in your body, it would be wise to consult with a healthcare professional. They can evaluate your overall health, check for any underlying conditions, and provide personalized advice.
In conclusion, while it is highly unlikely that you will continue to grow taller after the age of 40 in the traditional sense, factors such as measurement variability, posture, and overall health can influence how tall you appear. If you have any concerns about your height or health, seeking professional medical advice is always a good step.
