When you're expecting, your body sends more blood to the skin and stretches it over your belly, which may cause mild itching. You can manage it with loose, breathable clothing, cool baths, and moisturizers. If the itching is really bad, especially on your hands or feet, it could be a more serious condition called cholestasis. It's caused by a buildup of bile salts from your liver. Your doctor will watch you and your baby closely.
