For millions of people, chronic illnesses and depression are facts of life. A chronic illness is a condition that lasts for a very long time and usually cannot be cured completely, although some illnesses can be controlled or managed through lifestyle (diet and exercise) and certain medications. Examples of chronic illnesses include diabetes, heart disease, arthritis, kidney disease, HIV/AIDS, lupus, and multiple sclerosis.
Many people with these illnesses become depressed. In fact, depression is one of the most common complications of chronic illness. It's estimated that up to one-third of people with a serious medical condition have symptoms of depression.
Depression is draining. It can make any type of exertion -- going to the grocery store, cleaning up the yard, or exercising -- seem daunting.
"Energy loss is one of the key characteristics of depression. Some people feel that it’s the key characteristic of depression," says Robert E. Thayer, PhD, a psychology professor at California State University, Long Beach, an expert in managing mood, and the author of Calm Energy: How People Regulate Mood with Food and Exercise.

It's not hard to see the cause and effect relationship between chronic illness and depression. Serious illness can cause tremendous life changes and limit your mobility and independence. A chronic illness can make it impossible to do the things you enjoy, and it can eat away at your self-confidence and a sense of hope in the future. No surprise, then, that people with chronic illness often feel despair and sadness. In some cases, the physical effects of the condition itself or the side effects of medication lead to depression, too.
What Chronic Conditions Trigger Depression?
Although any illness can trigger depressed feelings, the risk of chronic illness and depression gets higher with the severity of the illness and the level of life disruption it causes. The risk of depression is generally 10-25% for women and 5-12% for men. However, people with a chronic illness face a much higher risk -- between 25-33%. Risk is especially high in someone who has a history of depression.
Depression caused by chronic disease often makes the condition worse, especially if the illness causes pain and fatigue or it limits a person's ability to interact with others. Depression can intensify pain, as well as fatigue and sluggishness. The combination of chronic illness and depression might lead you to isolate yourself, which is likely to make the depression even worse.
Research on chronic illnesses and depression indicates that depression rates are high among patients with chronic conditions:
People with a chronic illness as well as their family members often overlook the symptoms of depression. They assume that feeling sad is normal for someone struggling with disease. Symptoms of depression are also often masked by other medical problems. The symptoms get treated, but not the underlying depression. When you have both a chronic illness and depression, you need to treat both at the same time.
