Swollen Eyelids are a highly uncomfortable and alarming condition that causes various symptoms such as pain, discomfort, and vision changes. In this article, we will discuss the most common cause of swollen eyelids with their symptoms.
Causes:
1. Allergies
When it comes to swollen eyelids, allergies are one of the most common causes. An allergy is an overreaction of the immune system to a particular substance, such as pollen, dust, or pet dander.
The body releases histamine when it is exposed to an allergen, and this leads to the dilation of blood vessels and inflammation. Swollen eyelids due to allergies often come along with other symptoms such as watery eyes, sneezing, and a runny nose.
2. Infections
Swollen eyelids are commonly caused by infections. Bacterial, viral, or fungal infections can lead to inflammation and swelling around the eyes.
One of the most common infections that cause swollen eyelids is conjunctivitis or pink eye which is highly contagious and may spread easily from one person to another. Other symptoms of this condition include redness, itching, and discharge from the eyes.
3. Injuries
Swollen eyelids can also be caused by injuries to the eye or surrounding area, including scratches or bumps, fractures or orbital blowouts, and in some cases bruising or discoloration of the skin around the eye.
4. Contact Dermatitis
Contact dermatitis is a kind of skin rash that occurs when the skin comes into contact with an irritant or allergen, and it can also affect the eyelids, making them swollen and itchy. Common irritants that can cause contact dermatitis around the eyes include makeup, soap, and certain metals such as nickel.
5. Thyroid Disorders
Hypothyroidism and hyperthyroidism are thyroid disorders that may result in swollen eyelids. The thyroid gland, located in the neck, produces hormones that regulate metabolism. When this gland is overactive or underactive, it can lead to a variety of symptoms including those seen in swollen eyelids.
6. Chalazion
A chalazion is a kind of cyst that occurs on the eyelids because of clogging in the oil glands. It may cause your eyelid to swell and become tender when touched. In some cases, it can also get infected, leading to more inflammation and discomfort.
7. Blepharitis
The inflammation of the eyelids caused by the chronic condition is called Blepharitis. This causes swelling, severe itching, and redness around the eyes, as well as flaking of the skin. Blepharitis can be triggered by bacterial or fungal infections, allergies, and certain skin conditions.
8. Orbital Cellulitis
An infection called Orbital cellulitis is a severe bacterial disorder that affects the tissue around the eyes. It may cause severely swollen and red eyelids.
9. Graves' Disease
Graves' disease is an autoimmune disorder that impacts the thyroid gland, causing it to become overactive, resulting in a range of symptoms such as swollen eyelids. It is also known to lead to other eye issues, such as bulging of the eyes and double vision.
10. Preseptal Cellulitis:
Bacterial infection Preseptal Cellulitis affects tissue in front of the eye and can cause eyelid swelling and redness along with pain and tenderness around the eye. It is mostly caused by an infection from a scratch or insect bite.
11. Sinusitis
Sinuses are air-filled spaces in the skull, and sinusitis is a condition that affects these areas. When the sinuses become inflamed, it can cause a range of symptoms including facial pain, headache, and swollen eyelids. Sinusitis can be caused by allergies or infections or structural problems in the sinuses.
12. Cancer
Swollen eyelids can be a symptom of lymphoma or melanoma, also known as cancer. The cancers also cause swelling around the eyes and other symptoms such as lumps or bumps on the eyelids or changes in the appearance of the eyes.
13. Eczema
Eczema is a skin condition that has red, itchy, and inflamed skin. When it affects the eyelids, it can make them swell and become red.
14. Rosacea
Rosacea is a persistent skin disorder that causes redness and pus-filled bumps on the face. When it affects the eyes, it may result in swollen and red eyelids.
15. Insect Bites
Insect bites or stings around the eye region can bring about swelling and redness of the eyelids.
16. Trauma or Injury
Injuries to the eyes or around them may cause swelling of eyelids, which is usually because of physical trauma, such as being hit in the eye, or more severe injury like a fracture in the eye socket.
17. Medications
Swelling of the eyelids is a typical side effect that some medications, such as those used to treat glaucoma or other eye conditions, can have.
18. Dehydration
People who do not consume enough fluid or consume too much salt are likely to suffer from fluid retention which results in swollen eyelids.
19. Hormonal Changes
Swollen eyelids can be caused by hormonal changes such as those experienced during menstruation, pregnancy, or menopause.
