A 16-year-old boy in China briefly grew taller after undergoing a costly “body lengthening” treatment—but his gains vanished within weeks, sparking public debate over questionable height-enhancement therapies.

What happened during the therapy?

The teenager, identified only as Huang from Xiamen in Fujian province, enrolled in a program that promised to increase his height by stimulating growth in the knees.

• Duration: Six months
• Method: Regular sessions involving leg stretching and “knee activation” with medical equipment
• Result: His height increased from 165 cm to 166.4 cm (a gain of 1.4 cm)
• Cost: About 16,700 Yuan (US$2,350 or ₹2,07,000)

Despite the temporary result, Huang’s father reported that his son’s height dropped back to 165 cm just two weeks after stopping treatment.

The father’s response and clinic’s defense

Frustrated by the reversal, Huang’s father filed a complaint against the clinic. The facility offered a full refund, but insisted the boy was “too old to be corrected.”

The clinic also suggested that missing a few sessions affected the outcome, though the father argued the program should have delivered lasting results as promised.

What do medical experts say?

Doctors and endocrinologists have voiced strong skepticism about the therapy’s scientific basis.

Skepticism from specialists

• Wu Xueyan, endocrinologist at the Peking Union Medical College Hospital, dismissed the approach: “Humans are not noodles. It is unscientific to stretch a person longer.”
• Wu noted that while stretching can cause temporary height gains of 0.5 to 1 cm, this is similar to the natural daily variation in human height.

Why height fluctuates naturally

• People are taller in the morning than in the evening by about 1 cm.
• This is because the spine compresses under body weight during the day and relaxes at night.

Thus, the gains seen in Huang’s case may have been little more than temporary adjustments in posture and spinal compression—rather than actual bone growth.

Why permanent height gain is limited

Medical science agrees that once growth plates in bones fuse after puberty, the potential for natural height increase is almost nonexistent.

• Bone lengthening surgery is the only medically recognized procedure to increase height in adults, but it is invasive, painful, and carries significant risks.
• Non-surgical methods, like stretching devices or knee stimulation, lack scientific validation.

Experts warn that vulnerable families are often targeted with unproven therapies that exploit deep cultural and social pressures around height.

The cultural pressure to be taller

In China, as in many countries, height is often associated with attractiveness, confidence, and even career opportunities. This has fueled a market for height-enhancing therapies, ranging from supplements and hormone treatments to experimental procedures.

But doctors caution that these methods often prey on anxious parents and teenagers without offering sustainable results.

A cautionary case

Huang’s case illustrates both the desperation some families feel and the dangers of turning to unverified medical solutions.

• Short-term effect: 1.4 cm increase
• Long-term outcome: Returned to original height within two weeks
• Financial cost: Over US$2,000 lost, though refunded after dispute
• Lesson learned: Non-scientific height treatments rarely deliver permanent results

For now, the consensus among medical experts is clear: height after adolescence is largely fixed, and claims of non-invasive “growth therapies” should be treated with caution.

Related case: rare surgery for hairball removal

The report also highlighted another unusual medical case in China. A 15-year-old girl underwent surgery to remove a 2-kilogram hairball from her stomach, caused by trichophagia, a disorder where individuals compulsively eat their own hair. The mass had built up over six years before surgical intervention became necessary.

This underscores the diverse range of medical challenges doctors encounter—and the importance of scientific, evidence-based treatment.

TL;DR

A 16-year-old boy in China briefly grew 1.4 cm taller after a six-month “body lengthening” therapy, but lost the gains two weeks later. Experts say such treatments are unscientific and compare the effect to natural daily height fluctuations. The case highlights cultural pressures around height and the risks of investing in unproven medical procedures.
