Causes and Type of Skin allergies

Skin allergies:

Allergies are abnormal or hypersensitive responses of the Immune System to relatively harmless environmental antigens (substance which causes the allergy).

Diaper rash usually arises from some chemical irritation due to certain germs present in the baby’s stool. These germs break down the urea into ammonia, which irritates the skin.

Allergic conditions, such as Hay fever and sinusitis are also greatly aggravated by the presence of the germs within the tissues of the nose and throat.
The most common allergens are:
1. Grass and tree pollens,
2. Mold spores
3. dust mites
4. Animal dander.
Eating certain foods and food additives and being stung by insects can trigger allergic reactions in sensitive people. Such common disorders as eczema, hives, hay fever and asthma are often attributed to allergic reactions.

The most common cause of the skin allergies are:

1. Impairment in the immune system, which increases the risk of allergic reactions. This occurs due to stress on the immune system due to excess of the toxins.

2. The nutritional deficiencies, imbalanced diet, chemicals in the food chain due to preservatives and chronic intestinal yeast overgrowth.

3. Researchers have found that digestion also plays some role in the allergies. These are not just caused by the food. Proper digestion helps to remove toxins from our body. When digestion is disturbed, large amount of toxins get accumulated in the body and our body becomes over loaded with the toxins. This is what leads to allergies.

Itching is an unpleasant sensation, which we try to relieve by scratching. A certain amount of mild itching is normal for every one. Only if it is persistent and troublesome it becomes serious. Persistent scratching may produce swellings in the skin with deep scratch marks and small ulcers into which germs have found their way, causing much more trouble.

Allergies in general are defined as hypersensitivity to some foreign particle or the other. Different people have different kinds of tolerances for foreign bodies. When some people cannot adjust with certain elements in their surroundings, they may suffer from certain skin problems that are commonly referred to as skin allergies.

There is a sure way of determining whether your skin affliction is an allergy or not. If you have got a skin problem due to a cause that has affected no one else, then it is an allergic reaction. For example, several people may be exposed to dust. But if it affects you in a strong way, then you are allergic to dust.

Skin allergies could be in the form of itching, dry and scaly skin, eruptions, rashes, boils, etc. There are three main types of problems that are associated with skin allergies.

These types are as follows:-

(i) Dermatitis – This is the skin allergy which is caused due to contact with some substances. It is shown as an inflammation.

(ii) Hives – Hives is a fluid accumulation in the skin which shows up as a swelling. This is a temporary condition and heals with treatment.

(Iii) Prickly Heat – This is a red rash which occurs on the body. Prickly heat is generally caused due to excessive perspiration due to hot and humid climates.
