Q. Why do some people gain weight when they feel
stressed?A. People who eat in response to stress
are likely to find themselves packing on pounds for the same
reason other people gain weight – because they are eating more
calories than they are burning. However research also suggests
that chronic stress raises the level of chemicals that increase
appetite, especially for food rich in carbohydrates.
Q. Are you more likely to get sick when you are

Q. Why does my stomach hurt when I'm feeling
stressed?A. A combination of psychological and

heartburn and inflammation of the esophagus. Stress can also
cause abnormal contractions in the small intestine and colon,
which may result in abdominal discomfort.
