###Human: Why do I have swollen eyelids during pregnancy? ###Assistant: Hi. Swollen eyelids occur due to the retention of water during pregnancy. It will get resolved after the delivery. You have itching when the overlying skin is stretched and when it becomes dry from outside. Apply moisturizer regularly. Avoid going out in the sun. Start using Olopatadine eye drops twice daily. Pinch the nasal end of the eye after instilling the drops so that the drops can stay in the eyes and it prevents the drops from going into the nose.
