Bariatric dermatology focuses on the skin conditions and changes that occur in individuals with obesity, particularly those who have undergone bariatric surgery. Common skin issues include acanthosis nigricans, skin tags, and keratosis pilaris. After significant weight loss, patients may experience excess skin, striae (stretch marks), and changes in skin texture. Bariatric dermatologists work to manage these conditions, providing treatments to improve skin health and appearance, and addressing any complications that arise from rapid weight loss.
