Weight Gain

Weight gain occurs when an individual accrues additional body mass, resulting from an increase in body fat, muscle mass, or a combination of both. From a medical perspective, it is typically the result of a caloric imbalance, where the number of calories consumed exceeds those expended by the body through metabolic processes and physical activity. This surplus of energy is then stored as fat in adipose tissue. While weight gain can be intentional and beneficial in scenarios such as muscle development or recovery from undernourishment, it often refers to unintentional and possibly unhealthy increases in fat mass that may lead to overweight or obesity.

Medically, weight gain is a concern because it is associated with various health risks, including type 2 diabetes, cardiovascular diseases, certain cancers, and musculoskeletal disorders. It can be influenced by genetic factors, hormonal imbalances, lifestyle choices, medications, and psychological issues. Healthcare professionals assess weight gain by measuring body mass index (BMI), waist circumference, and evaluating lifestyle factors. Management involves dietary changes, increased physical activity, behavioral therapy, and in some cases, medication or surgery. Early intervention is critical for preventing potential complications and improving long-term health outcomes.
