Can Weight Loss Cause Stretch Marks

Can Weight Loss Cause Stretch Marks? Striae, more popularly known as stretch marks, are scars that develop in the middle layer of skin as a result of fragile skin stretching and tearing. While stretch marks are most often linked with pregnancy and weight increase, they may also be caused by weight loss. This shocks the majority of people since as you lose weight, your skin contracts, not expands.
