GlossaryRapid Weight Loss

significant reduction in body weight over a short period

Rapid Weight Loss, also known as Sudden Weight Loss or Quick Weight Loss, refers to a significant reduction in body weight over a short period of time, often due to extreme dieting, illness, or other medical conditions. While it might be intentional through methods like crash diets or intense exercise, it can also be a symptom of underlying health issues such as hyperthyroidism, diabetes, or gastrointestinal disorders. Rapid weight loss can lead to various health complications, including muscle loss, nutritional deficiencies, and hair loss (alopecia).
