Stretch marks, or striae distensae, are dermal scars that occur when the skin is stretched rapidly. Weight loss can sometimes lead to increased prominence of existing stretch marks, potentially causing them to become itchy. This sensation is linked to several physiological processes occurring within the skin.
Understanding the underlying causes of the itchiness provides avenues for managing discomfort and promoting skin health. The body’s reaction to changes in skin tension, alongside factors such as dryness and nerve fiber activity, contributes to the overall experience. Addressing these factors can significantly improve comfort levels during and after weight loss.
