Why do doctors monitor the concentrations of LDL and HDL in patients’ blood?

Both can cause cardiovascular disease.

Work cited

How are the concentrations of LDL and HDL associated with the risk for heart disease and associated disorders?

  • arteries will shrink and harden more of a chance for a stroke
  • HDL lowers removes cholesterol

What other molecules in a patient’s blood are monitored along with LDL and HDL?


What do the results of a cholesterol test mean? How do patients interpret each value?

  • shows total cholesterol levels
  • risk of disease
  • triglyceride levels

What can patients do to change the levels of LDL and HDL in their blood?


  • eat foods with lower cholesterol

ex: oatmeal, apples, salmon


  • exercise and eat foods with unsaturated fats

ex: run/walk three times a week for 30 mins.; salmon, tuna

How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health?

unsaturated-improve blood levels

saturated- increase HDL

trans fats- increase HDL
