Cholesterol levels tend to peak in older adults around age 60. Patients with two or more chronic conditions must maintain good health overall, and be mindful of decreasing high cholesterol levels. Particularly, older adults at higher risk for heart disease, taking measures to lower cholesterol is the best approach to lowering the risk for peripheral vascular disease, heart attack, or stroke. High cholesterol is caused by a variety of things, including foods with saturated fats or trans fats, certain meats, cheese and eggs, being overweight and having low activity levels. High cholesterol can also be hereditary, and age and sex also play a role.
