It may have come as no surprise that people with a medical illness or condition are more likely to suffer from depression. The reverse is also true: the risk of developing some physical illnesses is higher in people with depression.
People with depression have an increased risk of cardiovascular disease, diabetes, stroke, and Alzheimer’s disease, for example. Research also suggests that people with depression are at higher risk for osteoporosis relative to others. The reasons are not yet clear. One factor with some of these illnesses is that many people with depression may have less access to good medical care. They may have a harder time caring for their health, for example, seeking care, taking prescribed medication, eating well, and exercising.
Ongoing research is also exploring whether physiological changes seen in depression may play a role in increasing the risk of physical illness.
