I'm 37, about 100lbs overweight, 5'11 and fairly active...these are my recent cholesterol levels: 189total, 127ldl, 42hdl & 99tri. are these ok?

Yes, HOWEVER...: Your cholesterol levels are in the "normal" range but this doesn't mean you're not at increased risk of heart disease! half of those with serious heart disease have normal chol. Levels. Obesity is associated with high Insulin levels which causes inflammation which is the main cause of heart disease! see http://www.Sott.Net/article/242516-heart-surgeon-speaks-out-on-what-really-causes-heart-disease.

No and yes : Your HDL is great which is 42 but your LDL should not be more than 100 ., your's is 127 , once the patient touches 130 + ( LDL ) which does not come down after diet and exercise we start the patient on medication , triglycerides are fine , your total cholesterol is also within normal limits , i would try loosing weight because it will make a diff on your blood work.

Acceptible: In the abscence of coronary heart disease and no risk factors for CAD and no diabetes your LDL is acceptible. Your HDL should be 45. Aerobic exercise weight reduction and diet is advised.

I think so: Have you discussed your options with your physician, including possible surgery?
