Hello and thank you for posting your medical question on E health forum.
From the history provided it seems that you have a borderline high cholesterol level
Below 5.2 mmol/L Desirable
5.2-6.2 mmol/L Borderline high
Above 6.2 mmol/L High
Based on age, body weight, height, and presence of other risk factors like hypertension, diabetes, etc, the mode of therapy is advised.
Diet and exercise can help individuals with no risk factors.
Presence of risk factors and elevated cholesterol levels would need medications so that risk of heart disease, stroke etc can be reduced.
Since it seems that you are following a low cholesterol diet, you might add physical exercise and weight reduction in your routine.
You need to consult a dietitian for additional help with your diet management.
I hope this helps.
