You should go for lipid profile test. Check the level of cholesterol, triglycerides, LDL and HDL.  If your cholesterol level increase then you should take low fat diet with high amount of polyunsaturated fatty acids. Go for regular exercise. If needed you can take Chat Doctor.  It is prescription based medicine so consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer.
