Allergies are the result of a person’s body having hypersensitivity which could be to something that is drunk, ate, or applied to the body, even something in the air around us. The substance causing the allergy is called an allergen and can quite frankly be anything including the sun or even the air itself but the result is usually the same; a physical reaction occurs which can be quite severe.

Common allergens are those found in the food we eat and are also the ones that can cause the most serious of reactions in particular those of the nut family. Dairy products are also renowned as allergens, particularly cheese and milk but soy and wheat can also be a problem and an increasing number of people are having allergic reactions to processed foods.

Although in a small percentage, even chocolate can cause reaction in a few people and because food allergies mostly affect the immune system, respiratory and digestive systems, an allergic reaction should be taken seriously. Fish and other types of seafood can also have an adverse effect and some people put themselves at risk knowing they have a allergy but enjoy the food so much they still eat it.

Some foods just bring the individual out in rashes or cause the skin to itch like oranges, lemons, limes and other citrus fruits. It is peanut allergies which generally cause the most concern as the reaction to them, even a simple case of contact can be extremely serious and in some cases cause death.

Flowers are one of the most beautiful parts of nature but even these can prove to be dangerous for people who are allergic to pollen formed in certain flowers and even certain kinds of weeds and grass often affect respiratory system which can cause severe damage. Getting rid of plants with flowers around that individual might also help to a great extent but of course this is only if the flowers have been detected as the actual cause of the allergy.

Allergies relating to pharmaceutical products are not uncommon and can normally be detected fairly quickly as they cause swelling and rashes but sometimes the reactions cannot be seen and because of this damage to the organs may occur owing to the time it takes to discover the problem. Sulfur is used in most of the drugs that causes adverse reactions in people and the physician must observe quickly if the patient is allergic to any of the drugs before administering the same.

Metal is also another allergen which can cause skin problems; nickel is the biggest culprit but a small number of people can even have a reaction to gold and silver. Normally the reaction happens in the area of contact but not always but typical signs are swelling, skin irritation, rashes, and skin color changes.

The same piece of advice applies to all allergies; stay away from them and in the case of food, do not eat something that cause you a problem as allergies can be serious enough to kill.
