An allergic reaction occurs when the immune system overreacts to a normally harmless substance, known as an allergen. The signs and symptoms can vary depending on the severity and type of allergy, but here are common indicators:
Skin Reactions:
Itchy, red, or inflamed skin
Hives (itchy, raised welts)
Swelling of the lips, face, or tongue (angioedema)
Rashes or eczema
Respiratory Symptoms:
Sneezing
Runny or congested nose
Itchy or watery eyes
Coughing
Wheezing or shortness of breath
Chest tightness
Gastrointestinal Issues:
Nausea or vomiting
Diarrhea
Abdominal pain or cramping
Cardiovascular Symptoms:
Rapid or irregular heartbeat
Low blood pressure
Dizziness or lightheadedness
Systemic Reactions:
Generalized itching or tingling sensation
Swelling in various parts of the body
Feeling of warmth or flushing
In severe cases, a life-threatening allergic reaction called anaphylaxis can occur, which requires immediate medical attention. Anaphylaxis symptoms may include difficulty breathing, throat tightening, severe drop in blood pressure, rapid pulse, dizziness, loss of consciousness, and a sense of impending doom.
It’s important to note that these symptoms can also be caused by other medical conditions, so it’s crucial to consult a healthcare professional for an accurate diagnosis. If you suspect an allergic reaction, especially if it is severe or accompanied by breathing difficulties, seek emergency medical care immediately.
