PHARMD GURU Page 1 INTRODUCTION: RISK: Risk is the likelihood (or) the probability of experiencing some type of harm (or) losing something that one values. CHARACTERISTICS OF RISK: 1) Risk is not certain:  Risk is based on probability. Therefore, not everyone who is exposed to a risk condition (or) factor will have adverse outcome. 2) Risk is a relative concept:  Risk factors range from those that are only markers to minimally harmful situations to those that are markers of life-threatening situations.  Risk factors work together overtime to influence the likelihood of a negative outcome.  The longer the exposure to risk factors, the greater the likelihood the health problem will occur.
