An allergy occurs when you ingest or inhale something, which provokes a reaction from the body and makes you ill. The immune system of the person is tricked into thinking that what the person ate or inhaled is harmful for the body. This forces the body to react to the allergen.
The body produces antibodies and a chemical called as histamine. Histamine acts on the nose, throat, eyes, ears, skin and gastro intestinal tract and produces a range of uncomfortable symptoms that are typical of an allergy. Each time the body is exposed to the allergen, the body produces histamines, creating allergy symptoms. Here are some of the common allergies.
Symptoms Of Common Allergies
This happens when one encounters dust at home while sweeping or vacuuming. The common symptoms of a dust allergy are itchy and watery eyes, runny and stuffy nose and sneezing. At times, the person develops a mild rash on some part of the body.
During spring and summer, tiny particles are released from leaves and petals of flowers. These particles are called pollen. They freely float in the air and a person encountering them can develop an allergy called as pollen allergy. The symptoms of pollen allergy are similar to a cold. The person experiences a runny nose, sore throat and sneezing. The symptoms of course are milder as compared to the cold and disappear as soon as the person avoids contact with the pollen.
This allergy is caused in individuals who have highly sensitive skin. The skin reacts to different things like metal, jewellery like gold and silver, leather, oxidised metal etc. Some people are even allergic to clothing. Symptoms of a contact allergy include, rashes on the skin, redness and itching. They appear within 30 minutes of exposure while some may take longer. Other contact allergies include poison ivy, poison oak, dyes, medications and fragrances.
Food allergies are more common than believed. They are also potentially dangerous causing an array of uncomfortable symptoms like hives, eczema, swelling of lips, difficulty in breathing, swelling of the face, tongue and throat, wheezing, diarrhoea, vomiting, dizziness and fainting. The symptoms occur soon after having the food. They can cause a drop in the blood pressure, thickening of airways and a drop in blood pressure. Food allergies are often very difficult to identify and one should exercise extreme caution when selecting foods and reading labels. The common foods which cause allergies are eggs, nuts, crab, prawns, shellfish, milk, wheat and soya.
Safety with Food Allergies
If you are unsure about what you are allergic to, stop taking the food for two weeks and reintroduce it after two weeks to see if you are allergic to it. Avoid salad bars and buffet restaurants where you are not sure about what you are eating. Go in for food intolerance and allergy tests to see what you are allergic to. When in restaurants, avoid ordering dishes, which have too many ingredients in them. Always ask for the ingredients before you order a dish. Dust-proof your house to avoid dust mites. Avoid mouldy and dusty areas like basements and attics. Stay away from gardens and trees. Wear a mask while handling pets to avoid pet allergies from pet dander. Avoid exposure to fumes and other chemicals. Clean AC’s regularly.
