why is one side of yr body bigger then the other side?

It's not always so... It depends on a number of things: which part of the body you are talking about, the natural assymetry of the body etc.\n\nFor instance if you use one hand more than the other (like a tennis player might), the muscles would tend to increase in size as a result of the increased activity...\n\nIn addition, the human body is not perfectly symmetrical in anybody.

you are building more muscle mass which actually weighs more than fat

YOU MAY WANT TO SEE A DOCTOR. IF YOUR A DIABETIC IT MAY BE NUROPOTHY. IF NOT THEN IT MAY BE A CIRCULATION ISSUE. EITHER WAY IT IS NOT SOMETHING TO PLAY WITH IF IT IS ON THE LEFT SIDE BECAUSE IT COULD BE RELATED TO THE HEART.

Testosterone boosts growth in humans. Men have more testosterone which is why they are usually bigger. As men grow their larynx grows and the Adam's apple bulges.\n\nA larger larynx is also why men usually have deeper voices.

Your biceps will look bigger the bigger your triceps are.

Well, I wouldn't call it normal, but it isn't all that bad a thing either. I have a friend who is in your exact situation, but he's very proud of it. You should be too. And you never know, the rest of your body might just "grow" into it in a couple of years.

Why?\nThey are both at the ages where their form will change dramatically\nthey are both growing, and the taller the child will be the leaner they will tend to be.\nOne of my sons was always quite thin (not thin as in "too" thin, but *lean*)  but has now filled out to be 6' 2. Another of my sons is growing with the identical pattern and these can tend to have more growing pains too.\nAs long as your child eats regularly and a good balanced diet then don't worry. Don't go shoving junk food down them. How we eat as children comes back and either cares for us as adults or dogs us as in illness etc...A childs diet is essential to be balanced now, for a healthy body when older.

It's from puberty (about 10,11,12 these days-must be the streroids in the meat we eat) through later teens (18,19,20). Then again when she is pregnant. Another time would be during implants.\nAnd usually, it is common for both of them to get bigger at the same time, not just a "chosen" one (as your question suggests)

Most parts of a male are typically bigger than the same parts on a female (not all though, females typically have wider hips for example).  This phenomenon is known as sexual dimorphism.  The most likely causes of sexual dimorphism in humans are  competition between males for females (the bigger you are the better you are at beating other men, both in a physical fight and in a bluff) and female mate choice, where females tend to pick taller, broader men for partners.  Both of these factors have led to evolutionary pressure on males to get bigger.  The mechanism by which this occurs during development is closely modulated by testosterone.  The more testosterone a man has, the taller he grows, the broader his shoulders are, the bigger his hands and feet are and the squarer his jaw is.\nSome more interesting things about the hands of men and women, is that women tend to have narrower palms and longer fingers and men tend to have wider palms and shorter fingers.  Another interesting quirk is that the more testosterone a baby boy is exposed to in the womb of his mother (yes, women have testosterone too, just not as much as men!) the longer his second digit (pointer finger) will be compared to his fourth digit (wedding ring finger).  Hopefully these will be some interesting facts to put on a science fair project!

Please tell me where you read or who told you that lifting weights will cause problems with your growth!!\nIf it was true you wouldn't have had one arm bigger!\nLight weights with many repetitions are good for you no matter what your age.\n\nBeing unbalanced with one side of your body (it's not just your arm, it's your shoulder, back and chest muscles) may cause you to get back problems later in life.\n\nI played tennis since 7 years old and my coaches recommended from very early on to do light weights and to try and do more reps with my non-dominant side than with my playing arm.

According to this website:\nhttp://www.pponline.co.uk/encyc/0111.htm\nat puberty, the bodies of males are producing more testosterone, which leads to greather muscle development and bone growth, while the bodies of females are devoting their strength to pelvic bone growth and fat storage around the hips and thighs.  \n\nHere are a few other sites, some with explanations, some only descriptive:\nhttp://www.reference.com/browse/wiki/Sexual_dimorphism\nhttp://en.wikipedia.org/wiki/Sexual_dimorphism\nhttp://ndnd.essortment.com/sexualdimorphis_rcgt.htm\nhttp://www.rpi.edu/~verwyc/oh14.htm\nhttp://northonline.sccd.ctc.edu/judylearn/NTRONLINE/genderphysical.htm\n\n(These are pdfs):\n\nhttp://psych.ucsc.edu/matherlab/pdfs/KanazawaNovak2005.pdf\nhttp://www.as.ua.edu/ant/bindon/ant475/Papers/Camp.pdf

This is normal. I am 21 and my breasts grew at different rates. I can tell you that mine never really got to be the same size.My left is almost a whole size different. In about 80% of woman one breast is larger then the other.

Because you're super thin, and your body has digested the food overnight and it's moved.  Also when you lay down gravity is pulling at your body differently than when you're standing up.  It's pulling more firmly from every direction, when you're standing, it's just pulling you down.  \n\nDon't worry.  It's normal to be "skinnier" when you get up -- your body's had hours upon hours to digest food and revamp it's cells.

You might be a little on the skiny side rather than on the fat side.

no, that answer isn't right.  It has to do with weaker stomach muscles when you are born, at least that is what my OBGYN told me.

Join the club.. I have a D and a B. Buying bras is hell.I was told it has to do with which hand you write with and use most often. Like I'm right handed and my right one is much smaller then my left one. The way it was explained to me, majority of the size it fat. To because I use my right hand the most it burns more fat and the breast is smaller on that side. How accurate that is I don't know but that's how it was explained to my and in my case it makes sense.Hope it helps you.

Obviously go to a doctor to see if you have something wrong.  You just never know.  So have it checked out by a standard doctor first.  If it is nothing...then:\n\nGo to a chiropractor and get adjusted.  Sometimes it is just that you are out of alignment.\n\nAlso, you may have built up one shoulder by using it more than the other.  Do light weights with the other arm to equal them out if they are different in size.
