Involuntary weight loss refers to a decrease in body weight that occurs unintentionally, without actively trying to lose weight. It can be a cause for concern as it may indicate an underlying health issue. Involuntary weight loss is typically defined as the loss of 10 pounds (4.5 kilograms) or 5% of normal body weight over a period of 6 to 12 months or less, without a known reason. It is important to consult a healthcare professional if you experience involuntary weight loss to determine the underlying cause and receive appropriate treatment.
