Allergy Malaysia

Allergy symptoms are classified as mild, moderate or severe:

• Mild reactions include local symptoms (affecting a specific area of your body) such as a rash or hives, itchiness, watery/red eyes, hay fever and runny nose. Mild reactions do not spread to other parts of your body.
• Moderate reactions include symptoms that spread to other parts of your body. Symptoms may include itchiness, hives, and/or swelling and trouble breathing.
• A severe allergic reaction, known as anaphylaxis, is a rare, life-threatening emergency in which your body’s response to the allergen is sudden and affects the whole body. Anaphylaxis may begin with severe itching of your eyes or face. Within minutes, more serious symptoms appear, including throat swelling (which could cause problems with swallowing and breathing), abdominal pain, cramps, vomiting, diarrhea, hives and swelling (angioedema). You may also have mental confusion or dizziness, since anaphylaxis may cause a drop in blood pressure.
