Anger is a behavioural issue. It can become a medical problem if it is triggered by hypertension which may itself be triggered by anger issues. Hence, it can become a self-fulfilling cycle. Whereas anger is a non-medical problem the repercussions that it has are certainly of medical nature. If anger is not controlled in time and if you don’t take an appropriate anger test (or a series of anger tests) then multiple medical problems can arise.
