5) Cushing syndrome:

Cushing syndrome is a disease that occurs when your body is exposed to high level of steroids whether from outside the body as in the form of supplements or drugs for medical conditions like asthma, or from inside as a result of excessive secretion or tumors. People with Cushing experience stretch marks and easy bruising. The reason for easy bruising isn’t as direct as the above causes and is mainly thought to be a result of the rapid stretching of the skin due to the rapid weight gain of such patients especially in the trunk area owing to the accumulation of water and salts. This renders the connective tissue supporting the blood vessels weak and thin, causing easy tearing of such blood vessels especially at the sites of stretch marks causing the characteristic purplish stretch marks termed “stria rubra”.
