Individuals in the overweight or obese range of BMI tended to have a much greater risk factor for coronary heart disease, sleep apnea, arthritis, stroke, type 2 diabetes, hypertension, high cholesterol, gallbladder disease and certain cancers. To reduce your chances of developing these conditions weight loss is encouraged in patients with high BMI. Individuals within the normal and underweight groups are not immune from these conditions, only statistically less likely to develop them. Other risk factors and family history are used by doctors for a more complete picture of conditions patients should be monitored for.
