For some people, an increase in stress levels can cause a loss of appetite, which then results in weight loss. In fact, many studies have been conducted on the serious risks high levels of stress can cause to the human body. Continued weight loss caused by stress can also lead to fatigue, depression or eating disorders.
Eliminating, reducing or finding outlets to release stress, such as exercise may help your body return to its normal hunger patterns. If the weight loss continues, consult your doctor for assistance.
