Puffy Eyes Allergies: Causes and Symptoms
Swelling or puffiness under the eyes could be a result of several causes.
They include aging, water retention, allergies, heredity, etc.
Medically called Periorbital puffiness, it results from excess fluid in the tissues surrounding the eyes.
The puffiness might also accompany various other symptoms, making it uncomfortable.
Since the treatment of the condition depends on the cause of the puffiness, it becomes necessary to diagnose it.
This article will discuss puffy eyes due to allergies, their symptoms, and how to diagnose them.
How do allergies cause puffy eyes?
On exposure to substances that might cause an allergic reaction, your body releases a chemical called Histamine.
Histamine causes allergy symptoms in a person’s eyes, throat, nose, lungs, skin, or digestive tract.
It causes the blood vessels in the soft tissue around the eye area to puff up.
This leads to the eyes becoming red, teary, and itchy very quickly.
Swollen eyes are a response to inflammation due to allergens, injury, or infections.
Puffy eyes correspond to swollen eyelids due to fluid retention, lack of sleep, genetics, etc.
Some of the reasons that might lead to puffy eyes have been discussed here.
