Skin Rashes/Hives
One symptom of a preservative allergy can be the appearance of skin hives or rashes. This usually means that your body is responding to a substance you're allergic to. The skin may become red, itchy, and inflamed in areas that have come into contact with the preservative.
Difficulty Breathing
An individual with a preservative allergy might experience difficulty breathing. This can be due to the immune system's overreaction causing inflammation in the lungs, which restricts air flow and makes breathing difficult.
Swelling
Swelling of different body parts, particularly around the mouth and eyes, is another symptom of a preservative allergy. This swelling can be a part of the body's response to a perceived threat, leading to inflammation and swelling in certain areas.
Gastrointestinal Issues
Preservative allergies can also lead to gastrointestinal problems such as bloating, diarrhea, or vomiting. These symptoms occur as the immune system reacts to the foreign substance causing discomfort in the digestive system.
Severe Allergic Reaction (Anaphylaxis)
In severe cases, a serious allergic reaction known as anaphylaxis can occur. This rapid reaction can cause symptoms such as dizziness, fainting, rapid or weak pulse, and can be potentially life-threatening unless treated immediately.
Itching Sensation
An itching sensation, especially around the mouth, eyes, or the skin, can be a symptom of a preservative allergy. This sensation is typically caused by histamines, chemicals released by the immune system during an allergic reaction.
