Obesity/overweight in adults - clinical fact sheet and MCQ

03 June 2025 - Medcast Medical Education Team

Overview

Obesity is a chronic, relapsing condition marked by excessive body fat accumulation that adversely affects health. In Australia, 31.7% of adults are living with obesity and a further 34.0% are overweight. Overweight and obesity significantly elevate the risk of numerous chronic conditions, including cardiovascular disease, type 2 diabetes, metabolic dysfunction-associated steatotic liver disease (MASLD), several cancers (eg colorectal, thyroid, and liver), osteoarthritis, infertility, and depression.

Obesity is influenced by biological, psychosocial, environmental, and structural factors. It is not solely a result of individual behaviours. Treatment must reflect this complexity, and should avoid simplistic, weight-centric models. A person-centred, holistic, and inclusive approach is central to effective care.
