Over a third of medical problems that present to physicians in their offices and/or the hospitals are due to mental disorders. Doctors usually treat the patients' symptoms in hopes to make them feel better, without completely knowing the source of their problems. After running numerous tests and reviewing inconclusive results, physicians release their patients by telling them either nothing is wrong with them or following-up with them in hopes their symptoms will dissipate.
The causes of mental illnesses can come from numerous things. One being family history, two being past or present problems they may be facing, and three being sleep deprivation. The most uncontrollable cause of mental disorders is family history. It can take its toll on family members by seeing their loved ones suffering with a disorder, and then they live with the fear of knowing they may have inherited some form of it. Depression and stress can cause medical issues, such as fluctuations in blood pressure, headaches, and abdominal pains that can cause multiple visits to the doctor's office, and even the emergency room, just to be told nothing is found to be wrong.
