What does it mean that apolipoprotein aapo-a is 2.94?

My mother-in-law is 65 years old. A few days ago, physical examination found that apolipoprotein B was low (0.64g/l), while serum total cholesterol (5.9mmol/l) and high-density cholesterol (1.73mmol/l) were high. I don't know why. What should I do? thank you

It should be caused by unbalanced nutrition. It is suggested to eat more red dates, vegetables and fruits at ordinary times, take a walk in the morning and hit Tai Ji Chuan.
