Can I Grow 5 cm After 18?
While most people stop growing taller after age 18-20, it's possible to grow 5 cm (approximately 2 inches) after 18, but it's not common.
Several factors influence whether someone continues to grow taller after 18:
-
Growth Plate Closure: The primary determinant is the closure of the growth plates in your long bones. These plates are responsible for bone growth. In most individuals, these plates close between ages 18 and 20. However, in some individuals, the closure of the growth plates may be delayed. If these plates remain open past age 18-20, further height increase is possible. This is uncommon. ([Reference 1])
-
Gigantism: A very rare condition called gigantism, caused by excessive growth hormone production, can result in continued growth into adulthood. ([Reference 1])
-
Individual Variation: Anecdotal evidence suggests some individuals do experience height increases after 18. Online forums report cases of individuals growing several centimeters even after age 18. ([References 2, 3, 4]) However, these are exceptions rather than the rule. Reports range from 12-13 cm growth ([Reference 2]) to small increases of 1-5cm ([Reference 10]). One study reported that 27% of patients with growth hormone deficiency grew at least 5 cm after age 18 (for women), or 20 (for men). ([Reference 7])
-
Genetics and Other Factors: Genetics play a significant role in determining final height. Other factors, such as nutrition and overall health, also contribute. ([Reference 5])
It's important to note that many claims of significant height increases after 18 may be due to improved posture or measurement errors.
Conclusion:
While extremely rare, there's a possibility of growing 5 cm after 18, primarily due to delayed growth plate closure or in cases of gigantism. However, expecting significant height gain after this age is generally unrealistic.
