User: what are the physical changes associated with frequent or severe stress? How might stress affect the cardiovascular, immune, and digestive systems?

Weegy: With physical stress your body feels tired and and low in energy. You might experience stress related headaches, aches and pains, constipation or diarrhea, nausea, dizziness, increased heartbeat and even chest pain. [ There is a strong association between stress and cardiovascular disease. When you are experiencing high levels of stress your immunity is low so you may also be vulnerable to colds and flu and other stress related illnesses. ]
