Will obesity stretch marks disappear after losing weight?

Weight loss may or may not lead to the disappearance of stretch marks. Stretch marks result from damage to collagen fibers caused by excessive stretching of the skin. After weight loss, the skin gradually contracts, and this damage may be partially repaired. 1. **Possible disappearance**: As body weight decreases, the skin gradually contracts, filling in the wrinkles caused by obesity. Although stretch marks are caused by damage to collagen fibers, during the weight loss process, the body works to repair damaged tissues, allowing collagen fibers to gradually return to a normal state. 2. **Possible persistence**: For deeper stretch marks, even after weight returns to normal, the skin may not fully recover its original condition. After excessive stretching, the skin's elasticity is limited, making it difficult to completely eliminate stretch marks. Individual differences in skin repair capacity also affect the outcome—those with stronger skin regeneration abilities may see gradual fading of stretch marks, while others may find them persist. Patients are advised to maintain a healthy lifestyle and seek medical attention proactively.
