Adult Height Prediction
Maybe/maybe not: Prematurity is a broad category with survivors occasionally as early as 24 weeks up to more common 36-37. The smaller/earlier the baby the more likely they had or have predisposing factors that may limit final height. The less time in the neonatal ICU and less complications with their care, the less it will alter achieving their genetic potential. ...Read moreSee 1 more doctor answer
What is the last or latest possible age that a female can grow taller and reach her final adult height?
When centers close: Linear growth depends on having open growth centers. An x-ray of the wrist/hand is a common site to look for these since so many are available to see. When these centers are closed on x-ray, those in the rest of the body are too. The hormones that signal the transition into puberty accelerate the closure of growth centers. Most stop 3 inches after their first menses.This is usually by 17-18. ...Read moreSee 1 more doctor answer
My son is 12 and 4'9.5 and about 80 lbs. I am 5'2 and dad is 6'2-6'3. What is my son's predicted adult height.
5'11" or so: The basic height prediction assumes that a kid will achieve the average of both parents plus 2.5 inches in males. His height is about average for a 12 yo so he should be on track to reach 5'11. There are variables, since some kids enter puberty a bit later and finish growing later than others so their might be more. Both mom & dad are treated equally in basic height prediction. ...Read more
Hello, I am a young adult 21years old. I wanted to know whether those various height increasing medicines really help?
Scams: At age 21, you have almost certainly reached your maximum height. The medicines are promoted by people who know they do not work, but that most people will not ask for their money back (they're embarrassed). You're male, though, and you can add lean muscle at the gym and look great regardless of height; you'll be admired for this and it trumps how tall you are. Good luck. ...Read more
I know there are thousands of rare diseases but are there any known ones that cause adult height to signif. grow after years of no growth? I'm 39.
That's a strange one: because usually after the ends of the bones fuse in young adulthood, it is not possible for them to lengthen, which is what would be necessary for one to get taller. There is a condition called acromegaly that could cause some bones to get wider, so hands and feet and jaws and forehead can grow. If you are noticing this, you should be checked for pituitary problems. Good luck! ...Read more
Read a docs posts that person's growth can't be restarted but said research being done. Is there now a way adults height can restart growing again?
No such a thing: Linear growth is only possible when your growth plates are open when you are young ...Read more
Any truth to what I read--that 1-2 sodas/day, like Mountain Dew, can cause GH levels to rise & increase the height of adults (many yrs past puberty)?
Can you please specifically list all conditions or diseases that can result or bring on added inches of growth in height in adults years past puberty?
Are there any other conditions besides acromegaly that would bring on several sudden growth spurts (sev inchs) of height in adults near & past age 40?
Growth: Well before age 40 epiphyses get closed and vertical growth is not possible by any means. ...Read more
What causes spontaneous growth spurts in adults? Same height for yrs then out of blue had a growth spurt around 38 another @ 41adding inches to height
Endocrine Disorder: Spontaneous growth spurts in adults is abnormal. Normal human growth ceases by the time we reach 18-20 yo, when the growth plate in our long bones close. Growth is hormonally regulated via pituitary-mediated secretion of growth hormone, GH. Excess GH is concerning for an endocrine disorder, such as a pituitary tumor. Please see your doctor for a full evaluation and referral to an Endocrinologist. ...Read more
What conditions besides acromegaly would restart growth in 38 YO? Adult height held steady for yrs than out of blue grew 3 in taller. No other symptom
If your height doesn't change after 6-7 years can you be pretty certain that height is done growing? I'm asking for adults not teens or 20-somethings,

No: Weightlifting does not reduce the height of an adult. The most common cause of loss of height associated with age are degenerative changes in the spine and lower extremities. If the question is can weightlifting in children decrease your ultimate height, it may if done incorrectly. Resistance training can be done in kids but the focus should be on form with low weights and high reps. ...Read more
It could: Some children go into puberty relatively younger or relatively older than most of their same-gender peers. So a child's height at one point in time may not predict adult height well. This equation is better: boy's final ht = [(mom's ht + 5') + dad's ht]/2. Girl's final ht = [(dad's ht - 5') + mom's ht]/2. The final height should be within 2' (more or less) of the answer to the equation. ...Read more
Height calculations: Step 1: add parents' height in inches. Step 2: if child is male, add 5 inches to total from step 1. If child is female, subtract 5 inches from total from step 1. Step 3: divide answer from step 2 by 2. This is the predicted adult height of child, give or take 2 inches above or below. ...Read more
