I am 30 years old female. my total cholesterol is 227 trigl 178, hdl 31, ldl 160.4 how bad is my result?

Hi ldl. Low hdl: Your LDL should ideally be lower, but falls in range for initial dietary change and exercise therapy. Regular exercise can also help hdl, but may take several months to show a benefit. If you smoke, this needs to be stopped- suppresses HDL and damages he inner wall of your blood vessels, predisposing to depositing cholesterol in arteries.

Not too bad: In that range diet and exercise should help. No need for medication at your age.
