Obesity is a complex disorder involving an excess accumulation of body fat at least 20% over average desired weight for age, sex, and height or a body mass index of greater than 27.8 for men and greater than 27.3 for women. It increases the risk of diseases and health issues such as heart disease, diabetes, and high blood pressure. Nursing care management for patients with obesity includes identification of inappropriate behaviors that cause obesity, preparing a diet plan, determining nutritional knowledge, and providing information.
