Swollen lips when pregnant

Hormonal and fluid changes may alter how your skin feels, but a swollen lip is not automatically a normal pregnancy change. New toothpaste, cosmetics, foods, medicines, or supplements can irritate or trigger an allergic reaction. Dryness, a bite, dental work, or infection may affect one area. Angioedema causes deeper swelling that may involve the lips, eyelids, tongue, or throat; see [Angioedema](/conditions/angioedema/). The timing, speed of onset, one-sided or two-sided pattern, and associated symptoms help a clinician narrow the cause.

Pause any product that touched the lips recently and rinse gently with water. Apply a cool compress wrapped in clean cloth for short periods, and use a plain emollient for dryness if the skin is intact. Keep a record of foods, medicines, supplements, and exposures before the swelling began. Speak with your obstetric or primary-care team before using an over-the-counter medicine, especially if you have asthma, allergies, or take regular treatment.

Call emergency services for difficulty breathing, noisy breathing, throat or tongue swelling, trouble swallowing saliva, collapse, or swelling that is spreading quickly. Seek same-day advice for hives, repeated vomiting, fever, worsening pain, warmth, pus, or a new medicine-related reaction. Contact your maternity service promptly if facial swelling occurs with severe headache, visual symptoms, sudden swelling elsewhere, or upper abdominal pain.

Ask whether the swelling needs examination today, which exposures should be avoided, and what pregnancy-compatible options can relieve itching or discomfort. Tell the clinician exactly when it started and whether your tongue, throat, eyes, or skin are affected.
