Question 1

nine month old head size 97 percentile, is that bad?

Accepted Answer

Depends: If it has changed from the 10% to the 97% since birth, I would be more concerned than if it was big all along. If his height and weight are on the larger side it would be more consistent with a normal variant. It didn't bother me much in life, except when looking for a helmet that would fit.

Question 2

at sons year od checkup dr ordered an ultrasound of his brain for monday said his head size is in 95th percentile he appears very healthy was surprised to find out he's 18 lbs only because he loves to eat very active fun baby

Accepted Answer

Hello. : Hello. Doctor's check  babies head sizes (head circumference) and compare it on a chart to other children of that age. 95th percentile means that his head is larger than the "average" head size at that age.  I am glad that you have a healthy and active baby. Take care.

Question 3

ive read that head size is proportional to height. my childs in the 97th percentile for height but only 30th for head circumference. is that something to be worried about?

Accepted Answer

Not really: It's more useful to follow the rate of growth of head.  In most of healthy infant, head circumference increases 1/2 inch per month in the first 4 months and 1/4 inch per month for the next 8 months.

Question 4

my 8 week old son dropped from 95th percentile in height at birth to 89th percentile at his 8 week visit. his head size stayed about the same. is this cause for concern or is this normal?

Accepted Answer

: If the percentiles are followed and BMI is normal, his growth is acceptable. Watch for a pattern of poor weight gain, decreases in BMI and two or more percentile growth lines on his growth curve. Discuss any feeding issues with your physician and a virtual consultation with HT is available to review as well.

Question 5

does human head size change with age?

Accepted Answer

Head size: Not much after maturity unless you get acromegaly.

Question 6

is head size bodily proportional to height?

Accepted Answer

Usually it is so..: Normally, head-size is proportional to height. In pediatric care, head circumference, length (height) and weight measurements are very important part of each well visit. Headsize and height will continue to grow proportionately until shortly after puberty. Once max growth in height is achieved, head size stops even if one continues to grow sideway (unfortuately too much in us). Good luck.

Question 7

will my head size increase if i continue to gain weight?

Accepted Answer

Not after puberty: Your head grows fastest during first 2 yrs of life, then slows down until puberty with growth spurt. Once you're done with growth in height--about 16-17 for girls, and 19-20 for boys, your head will not likely have any significant growth--except maybe for gigantism. You are now 45, your headsize won't change even as you are growing sideway. Keep healthy and ideal body weight. Cosult doc. Good luck.

Question 8

my son age is 10 month & his head size is 49.50, is it is normal ?

Accepted Answer

Head size : 49.5cm is larger than normal per chat attached. That does not automatically mean that your child has something terribly wrong. In some families there is a tendency to have large heads without any medical problem. Doctors mostly worry when the head size increases more quickly than expected, as this could mean there is a problem causing rapid increase in the head size.

Question 9

my head size is small when compared to my body.i'm 21 height is 179 cms and 135lbs.what should i do now??thanks in advance.

Accepted Answer

See endo: if ur tests are normal for CA, PTH, nothing to do.

Question 10

my son is 15 just about taller then me but we have the same head size is this normal? will he grow into it? it isnt hereditary either?

Accepted Answer

: This post is confusing as you say there is no hereditary factor to his head size but he is your son with the same sized head! 80% of adult head size is present by age 9 and it matures/grows much slower through the end of puberty. I don't see this as a problem.
