What does obesity cause to the human bodies ?

From every side possible,,, for example,

Does it really -
.. reduce Intelligence ?
.. decrease Height ?
.. etc

Also, if the person lost his obesity, would his body get back to normal 100 % ?

Obesity leads to diabetes, high cholesterol, high blood pressure, disk disease, heart disease, varicose veins, gall bladder problems, pancreatitis. It contributes to joint problems such as bad hips and knees. People who are obese lose muscle tone because they don't move much. Breathing problems are common, shortness of breath, as well as sleep apnea, which can be very serious, sometimes fatal. Obesity can lead to depression or a persistent sense of sadness and unhappiness. There is also research to suggest obesity increases risk of certain kinds of cancer.

I don't think it actually affects intelligence or height, though disk disease can eventually make you shorter. However, obese people may be viewed by society as being less intelligent because people sometimes react that way to someone who is different.

If the person lost the weight his body could get back to normal in most ways. Certainly health would be much improved. However losing a lot of weight can lead ot lots of loose or excess skin in different areas of the body.

It doesn't really reduce height... It may make someone slouch or have the illusion they are shorter because they are so wide. The intelligence doesn't have anything to do with it, I think. It could restrict the lungs from totally expanding and cause asthma.
