Weight gain refers to an increase in body weight that can result from lifestyle factors, medical conditions, or hormonal imbalances. While gaining weight is a natural process for growth or certain life stages, excessive or unwanted weight can negatively affect physical health, energy levels, and self-confidence. Factors including poor diet, lack of exercise, and stress often contribute to gradual weight gain over time. Addressing the root causes is essential for achieving a healthier weight and improved well-being. With the right treatments and support, individuals can effectively manage their weight and reach their health goals.
