Allergies That Happen Due to Vitamin D Deficiency
An allergy is a defensive reaction of the immune system when a foreign body is found in the body. The allergen could be pet dander, bee venom, pollen, or even food that your body can't accept.
When the allergens attack, the immune system releases an army of antibodies to fight it. The antibodies will be produced each time your body comes in contact with a harmful allergen.
The allergic symptoms—inflammation, sinuses, digestive issues, and blocked airways—you experience are a result of your immune system’s reaction to those allergens.
