my son wants to know if his habit of?

Actually is will cause problems in later years. His teeth will become weak and cause pain. His stomach will create a dependency for food digestion assistance from the soda. His sugar level will retain a high level that could create a problem in the pancreas. He could actually develop a blood pressure problem at a relatively young age.

It is not a habit; it is called selfish desire complex. You and him need to talk; maybe he needs to talk to a doctor.

Ye it will but thats ok cause I drink 5 liters of coke or pepsi a day!

I don't feel it's good for him. Have him drink chocolate milk and other flavored milk instead. a 1-3 liters lasts us for 2 months around here. a case lasts a 3-4 months or more. Nothing in excess good or bad is good for your stomach.

Drinking lots os soda can severely wear down your tooth enamel. It also causes weight gain from the many extra calories. If he doesn't have heartburn than his stomach is probably fine.

That amount of soda will kill him in a few years, and make the next few in the meantime absolute hell. He'll become extremely obese, have heart problems, blood pressure higher than mt everest, and a plethora of other problems. You should take this issue very seriously.

it'll damage your health. Bad. And If he drinks to much fizzy drink his stomach is gonna fill up with gas and he'll get a stomach ache and he'll fart alot. I would know happen to me once!

OH YEA! You kidding me? Have you seen what it does to toilets. An nutritionist will tell you the ideal amount of soda to drink per day is 0. Get your son drinking water, nature's soda. :P

drinking 2 much soda

Soda is one of the worst things you can put into your body. It can destroy your liver.

all that sugar is very very bad for him, that much sugar per day can mess with your body. and that much caffiene, chemicals, etc, yes it could mess with his kidneys.
