10 Symptoms of Stress
Symptom #8: Appetite Changes
Stress may cause a fluctuation in appetite. Sometimes you may find yourself with no appetite and other times you may be raiding the refrigerator at night. Stress stimulates the brain to secrete hormones that activate the sympathetic nervous system. A stress hormone, called corticotropin-releasing factor, suppresses appetite and decreases the body’s natural hunger hormone. It is not uncommon for people with high levels of stress to have elevated levels of this hormone, resulting in appetite suppression.
It is uncertain whether stress will cause your appetite to increase or decrease. Depending on the type or seriousness of the situation, you may eat more or less. During final exams, you may want to eat all kinds of junk food, but after breaking up with a boyfriend, you may lose your appetite altogether. It is not fully understood why this may happen, however it is likely related to stress hormones and their influence on hunger and fullness.
Some people experience nausea when eating under stressful circumstances. This may lead to appetite suppression. Once the individual is convinced that this is the way that their body reacts when they eat under stress, it may become more of a habit, further perpetuating the cycle.
Another effect that stress has on food is the perception of control. Some may begin to restrict and binge on food because having control over food may help soothe the anxiety. Stress can trigger eating disorders so it is important to stay mindful during this period of time.
