How to reduce cholestrol and how much is a red alert

Hi Gauri, I think it depends on the ratio between HDL and LDL. Also, triglycerides level. If you let people on this forum know those results they will be able to advise you.

I'd be more concerned about your blood glucose levels and not worry too much about your cholesterol.

My last two cholesterol totals have been 5.9 but the HDL (good cholesterol) has gone up and my LDL (bad cholesterol) and triglycerides have gone down. I’m not keen to take Statins and my GP has agreed that as my numbers are improving to stay off them. You need to read up about cholesterol and Statins and make your own decision, don’t be pressurised into taking them without being informed. I also agree with @NoCrbs4Me, your HbA1c is more of a worry.

Your HbA1c assuming it's 7% (53 mmol/mol) is pretty good. As far as your cholesterol goes you need to know the ratios as @mazza 2 had said.
