- What is Anorexia and How Does it Affect the Heart?

- QUESTION: I am trying to fully understand the extent of an illness called
- "anorexia". Can you tell me something about it and please describe any
- actions it might have on the heart. Please consider this question for your
- column as it is most important to me.

- ANSWER: Anorexia nervosa is a serious illness. Fifteen percent of all
- anorexia sufferers die, which makes it one of the deadliest of all psychiatric
- disorders. Sudden deaths among anorexics are often due to the serious damage
- that anorexia causes to the heart.
- Researchers have known for a long time that anorexics have abnormal heart
- rhythms, including heart rates that are too fast or slow or lack the proper
- rhythm. Their hearts are also shrunken in size. It had always been thought
- that when the body is starved, the heart and the brain are spared at the
- expense of other parts of the body, but an anorexic's heart appears to lose
- more weight and size proportionately than the rest of the body. The size of
- the left ventricle, one of the chambers of the heart, in anorexics is
- especially reduced. Bulimia--eating and then vomiting--can also cause heart
- problems due to chemical imbalances in the body.
- Because of these heart changes, anorexics cannot exercise as long as
- normal during exercise stress tests. Their heart rates and blood pressures do
- not respond normally to the extra effort of exercise, as a healthy person's
- would. It is still not known whether the heart returns to normal after a
- treated anorexic returns to a normal weight or whether these abnormalities are
- permanent. Some studies have shown that the heart does increase in size as
- weight is gained.
- As a part of the treatment for anorexia nervosa, anorexics must therefore
- be followed carefully with frequent evaluations of their hearts.
