As we age, the height of most people decreases by at least a few centimeters compared to when they were younger. In addition to osteoporosis, there is another reason why our bodies tend to “shrink.”
Height loss is a typical characteristic of aging. Starting from the age of 40, we often lose about 1.2 cm of height every 10 years, and the rate of height loss accelerates when we reach our 70s.
The body of a person grows from short to tall, peaking in height during their 30s. After reaching the age of 40, we typically lose about 1.2 cm of height every decade, with a faster rate of decline as we enter our 70s.
According to scientific research, the primary reason for this is changes in bones, muscles, joints, and even posture.
Each of us will reach peak height and weight development in adulthood. After that, as we age, we become lighter and shorter, even if we still consume adequate nutrition – (Photo: CMD)
Part of our body is held upright by the spine. One reason for height loss, especially in women, is osteoporosis, a condition that can be prevented and treated by medicine. Osteoporosis means that bones become porous and weak. The weight of the body compresses the vertebrae of the spine, causing them to shorten – hence, our height decreases.
However, the most common reason for height loss in old age is not osteoporosis. The intervertebral discs located between the vertebrae act like rubber cushions. These discs naturally shrink and change shape as we age – primarily due to loss of tissue and water. When these discs shrink, the vertebrae come closer together.
Moreover, our spine is not straight like a stick. In fact, it is a series of curves in the neck, upper chest, and lower back. These curves of the spine increase as we age, possibly due to muscles becoming weaker. Additionally, the muscles surrounding the spine become less flexible, making it difficult to stand up straight.
How to Prevent Height Loss in Old Age?
Height loss is a normal occurrence, so there is no need to worry excessively about it. However, if the rate of height loss occurs too quickly and you frequently experience back pain, it is advisable to visit a healthcare facility for an examination, as you may have bone-related issues, such as osteoporosis.
We can also reduce the risk of height loss as we age while protecting our bone health starting now by: exercising regularly, engaging in light weightlifting (which applies pressure to bones and helps strengthen them), following a diet rich in calcium and vitamin D to support bone health, avoiding smoking, and limiting the consumption of alcohol and caffeine.
