Basic Information Description Changes and demands in your life can result in stress, which is the physical, mental, and emotional reactions you experience. The changes can be both large and small, and each person will respond to life's changes somewhat differently.
Some people are more susceptible than others to stressful situations.
Positive stress can be a motivator, while negative stress occurs when these changes and demands are overwhelming to you. Stress can affect any body system and aggravate any chronic disease. Frequent Signs and Symptoms Physical symptoms include muscle tension, headache, chest pain, upset stomach, diarrhea or constipation, racing heartbeat, cold clammy hands, fatigue, profuse sweating, rashes, rapid breathing, shaking, tics, jumpiness, poor or excessive appetite, weakness, tiredness, and dizziness. Emotional reactions include anger, low self-esteem, depression, apathy, irritability, fear and phobic responses, difficulty concentrating, guilt, worry, agitation, anxiety, and panic. Behavioral reactions may cause alcohol or drug abuse, an increase in smoking, sleep disorders, overeating, memory loss, or confusion.
