An allergy occurs when our immune system reacts to a substance foreign to our body. The immune system produces antibodies in that case. When a person has an allergy, it means their immune system has been attacked by pollen, bee venom or pet dander or food that normally doesn’t react with most people. The severity of any allergy varies from person to person and could range from mere irritation to sometimes life-threatening emergency. Allergies basically cannot be cured but treatments can help in relieving the allergy symptoms. Here in this article, we would be learning about the symptoms of various allergies.

Symptoms
Allergy symptoms depend on the substance by which they are invoked and can definitely affect our airways, sinuses and nasal passages and most often our skin and digestive system. Some of the severe cases have also been noticed in which allergies could trigger a life-threatening reaction known as anaphylaxis. Some of the common symptoms noted are:

• Hay fever or allergic rhinitis: It can cause sneezing, itching of the nose, eyes or roof of the mouth. Sometimes, it can also lead to a runny or stuffy nose. Our eyes can get watery, swollen and red.
• Food allergy: It can produce tingling in the mouth along with swelling of the tongue, face, lips and also throat. Hives and anaphylaxis are caused by this allergy only.
• Insect sting allergy: It ends up swelling a large area, most often the site of the sting. A person can feel itching all over the body. Acidity, coughing, wheezing or sometimes shortness of breath can also occur.
• Drug allergy: It doesn’t happen much but it can be fatal if it does. Hives, rash, itchy skin are some of the common symptoms of this disease. Sometimes, when it gets fatal, it can lead to facial swelling, wheezing and in extreme cases, anaphylaxis.
• Atopic dermatitis: It is an allergic skin condition which is also known as eczema. It can cause the skin to be itchy, reddened, and sometimes flaky or peeling.

Anaphylaxis
Signs and symptoms of this fatal condition are:

• Unconsciousness
• Drop in blood pressure
• Severe and frequent shortness of breath
• Rashes in skin
• Sometimes a rapid and weak pulse

It has been scientifically proven that professionals can sometimes fail to recognize these symptoms correctly and may overlook them. If these are left untreated then the person suffering from an allergy might get increasingly weaker. When this happens, it is sure to affect your daily life and reduce your performance. Misdiagnosing and delay in getting proper treatment can sometimes prove to be fatal. So, it is advisable for everyone to be aware of these signs and symptoms.
