Lips swell primarily due to fluid build-up in the skin tissue or underlying inflammation. These reactions can range from mild to severe and stem from various causes, as shown below.
Common Causes of Lip Swelling
Here's a breakdown of the most frequent triggers:
- Allergic Reactions: Exposure to allergens such as certain foods, medications, or insect bites can lead to an allergic reaction causing swelling.
- Example: A person with a peanut allergy might experience swollen lips after eating something containing peanuts.
- Angioedema: This condition causes swelling deep within the skin, often affecting the lips, face, and throat. It can be hereditary or triggered by allergens or medications.
- Practical Insight: Angioedema can be life-threatening if it affects breathing. Seek medical help immediately.
- Injuries: Trauma to the lip area can cause swelling as a natural response to the injury.
- Example: A lip injury from a fall or a hit can cause immediate swelling.
Other Potential Causes
While less common, these factors can also lead to swollen lips:
- Infections: Bacterial or viral infections in the lip area can trigger inflammation and swelling.
- Sunburn: Overexposure to the sun can cause inflammation, resulting in swollen lips.
- Dental Issues: Infections or procedures related to teeth or gums may sometimes cause adjacent lip swelling.
- Certain Medical Conditions: Some systemic illnesses can also manifest as lip swelling.
