The fastest rate of growth is usually 1 to 2 years after puberty has started. Developing physically into an adult takes 2 to 5 years. Most boys will stop growing taller by age 16 and will usually have developed fully by 18.
An adult cannot increase their height after the growth plates close. However, there are plenty of ways a person can improve their posture to look taller. A person can also take preventive measures against height loss as they age.
Around 60 to 80 percent of a person's height is determined by the genes. The remaining 20 to 40 percent is due to environmental factors like lifestyle and nutrition. It is said to be almost impossible to grow height after the age of 18.
People usually grow until they reach 18 years of age. Before then, a range of environmental factors can affect how tall they become.
Early bloomers may start to notice changes in their bodies as early as age 10, whereas late bloomers may start at age 14. Of course, these changes could easily fall anywhere in between. Those who started on the later side, can expect to keep reaching new heights until the age of 18.
As mentioned in one of the articles one good way to see if you still have growth potential is to X-ray a wrist- the test is called a Pediatric Bone Age. It will show if your growth plates are still open. A doctor can also request lab tests- checking for hormones- such as thyroid, growth hormone and sex hormones.
On an x-ray, growth plates look like dark lines at the ends of the bones. At the end of growth, when the cartilage completely hardens into bone, the dark line will no longer be visible on an x-ray. At that point growth plates are considered closed.
Regular exercise, especially weight-bearing and high-intensity activities like running, jumping, and strength training, can stimulate bone remodeling and increase bone density, which can help people grow taller.
What are the signs of growth spurts? Changes in your child's height and weight caused by increases in bone, muscle and fat are the most immediate signs that your child is experiencing a growth spurt. Other signs of a growth spurt include: Decrease or increase in appetite.
The term “late bloomer” refers to a child who goes through puberty later than their peers. Constitutional growth delay, the medical term for this condition, runs in families. Late bloomers will catch up on their growth and have standard adult height, although it may take a little extra time and patience.
Increasing your height after 18 is not possible, even through nutrition and exercise, because the growth plates stop growing. The growth plates (epiphyseal plates) are present at the end of long bones.
Children reach puberty at different ages. Delayed puberty is when boys have little to no genital growth by age 14, or girls have no breast development by age 13, or no periods by age 16. You may also hear this called being a “late bloomer”.
Delayed puberty can be caused by an underlying medical condition (e.g., celiac disease or a hormone deficiency). There's often a hereditary component to delayed puberty. If a parent was late in starting puberty, it's more likely that his or her child might be, too.
Changes in Boys
They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
At age 17, your son is about to start the last stage of there adolescence, that phase between childhood and adulthood. But they are still growing -- literally.
