A​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​n overweight patient comes to a clinic complaining of fatigue, swollen feet, and shortness of breath. She also admits that sometimes she feels that she cannot think clearly. She works at a local retail store, and she is on her feet all day. When s​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​he isn’t working, she doesn’t do any exercise. With her weight, she finds it hard to walk too much. Explain the strain she is putting on her vasculature and respiratory system, and explain what may be involved in this patient’s signs and sy​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​mptoms.
