Welcome to e health forum.
Here are the desirable levels of blood lipids for normal adults-
Total cholesterol levels - Desirable levels - Less than 5.2mmol/L.
LDL level - Desirable levels - range of 2.6-3.3 mmol/ L ;
HDL level - Desirable levels - ABOVE 1.5 mmol/ L and
Triglycerides - Desirable levels - less than 1.7mmol/L.
In your case, the Total serum cholesterol level is at the borderline level, and levels of LDL, HDL and Triglycerides are within the normally acceptable range. Hence you do not have to panic. Regular exericise, proper dietary measures will help to maintain or even improve your lipid profile results.
Some facts to remember:
Diet. Saturated fat, trans fat, and cholesterol in the food you eat increase cholesterol levels. Reducing the amount of saturated fat and trans fats and cholesterol in your diet helps lower your blood cholesterol level.
Weight. In addition to being a risk factor for heart disease, being overweight can also increase your cholesterol. Losing weight can help lower your LDL, total cholesterol levels, and triglyceride levels, as well as raise your HDL.
Exercise. Regular exercise can lower LDL cholesterol and raise HDL cholesterol. You should try to be physically active for 30 minutes on most days.
Medical conditions including diabetes, hypothyroidism, liver and kidney diseases can occasionally result in elevation of cholesterol levels. Hence regular screening and treatment of such conditions is very important.
