Respiratory issues: Allergies often affect the respiratory system, leading to sneezing, coughing, nasal congestion, runny nose, and itchy or watery eyes. These symptoms are typical in allergic rhinitis, also known as hay fever.
Skin reactions: Allergies can cause skin rashes, hives, itching, and eczema. These symptoms are particularly common in contact dermatitis, where the allergen comes into direct contact with the skin.
Digestive problems: Some individuals may experience gastrointestinal symptoms such as abdominal pain, bloating, diarrhea, or vomiting after consuming certain foods or substances they are allergic to.
Anaphylaxis: In severe cases, allergies can trigger a life-threatening reaction called anaphylaxis. Anaphylaxis involves a rapid and severe response throughout the body, resulting in difficulty breathing, a drop in blood pressure, and potentially leading to loss of consciousness. Anaphylaxis requires immediate medical attention.
