Skin Rash or Hives
A common symptom of allergy to biological agents is skin abnormalities such as a rash or hives. These can take the form of red, itchy bumps or patches on the skin which may also be swollen or painful. They can appear quickly and spread across the body.
Respiratory Issues
Allergy to biological agents can cause discomfort in the respiratory system. This can manifest as wheezing, difficulty in breathing, prolonged coughing, or shortness of breath. These symptoms often appear in reaction to the allergen being inhaled.
Nasal Symptoms
Often, allergens can trigger symptoms in the nasal passageways. These can consist of a stuffy or runny nose, itching or sneezing. This is the body's way of trying to expel the irritants from the system.
Eyes Irritation
Another potential sign of allergy to biological agents is eyes irritation. It can lead to red, watery, itchy eyes that may be sensitive to light. In severe cases, there may be swelling around the eyes.
Digestive Problems
When the allergen is ingested, it may lead to digestive issues. Symptoms such as nausea, stomach cramps, vomiting, or diarrhea can often be experienced. These symptoms are the body's response to something it perceives as harmful.
Anaphylaxis
This is a severe and potentially life-threatening allergic reaction that may involve several parts of the body at once. It causes rapid pulse, lightheadedness, severe shortness of breath, and loss of consciousness. It requires immediate medical attention.
