Not with this clinic, no, but I would say that they will certainly set you up with a dietician to work with you to change your child's diet. If your son has a weight problem, they will want him to lose weight.
It is not usual to give children statins because there haven't been studies on children to prove their safety. One thing that they MAY tell you is that when your son goes through puberty, he may be somewhat protected by the puberty from heart damage as far as the HDL and LDL are concerned. I DON'T know what they would say about the triglycerides, however. I would think that they are more worried about the triglycerides, though high cholesterol numbers are certainly an issue.
Exercise helps the LDL number go down. But to get the HDL lower, his diet has to change.
Another thing they will want to know is the family history. Do you know your and your husband's family histories where cholesterol is concerned? If you don't, call your families up and talk to them about it. It is important for the doctors to know if this is hereditary.
Good luck - I hope that they can help your son.
