In a nutshell, an allergy can be defined as an abnormal reaction from an individual’s immune system normally against a harmless substance. Individuals with no allergies would not have a reaction to these substances, or allergens, but the body’s of those who do release certain chemicals and it is these that cause the allergy symptoms.

An allergy can range from such things as itchy eyes to rashes to runny nose and is so widespread that they can affect 25% of the population at some stage of their lives. People have to be aware though, that these symptoms can be caused by factors other than an allergy as well, and could well be from a disease instead. More or less anything can be classed as an allergen for an individual but the most common come from pollen, dust mites, pets, insects, industrial chemicals, certain medicines and some foods like eggs and milk.

Common Allergic Reactions

The immune system of an allergic person reacts by producing special kinds of antibodies called IgE when it thinks it is being “damaged” by an allergen, and these antibodies attack the invader. This procedure then causes other blood cells to discharge other chemicals, which together with the antibodies cause the allergic reaction symptoms.

Food Allergies

A food allergy occurs when someone’s immune system reacts adversely to a particular type of food. When this happens it causes inflammation in certain bodily tissues and can even be life threatening. A food allergy should not be confused with food intolerance because, although in both situations the body can react to even a very small amount of food, food intolerance is not caused by an individual’s immune system; rather, it’s the digestive system.

Although actual food allergies are very rare and tend to run in the family, some people avoid consuming specific foods because they are under the mistaken assumption that they’re allergic to them. On average, only one in hundred adults and three in a hundred infants have food allergies. An individual would be more at risk if they or their family suffer from any allergic conditions such as asthma, eczema or hay fever. Only a medical professional will be able to diagnose somebody as having a food allergy.

Food Allergies

In principle, people could be allergic to any type of food, but the most common ones appear to be the following: milk, fish, shellfish, eggs, wheat, soya beans, peanuts and certain fruit and veg.

Food allergies are usually diagnosed by blood or skin tests, or a going through a food elimination program.

People with personality disorders may have conditions such as not being able to live with others, not being able to maintain relationships with other people, finding it difficult to control emotions or upsetting other people when distressed.

Causes of personality disorders can include genetic makeup, mental or emotional state or brain problems. There are three types of personality disorder: suspicious, emotional and impulsive, and anxious.

Suspicious personality disorders are where the sufferer is often paranoid of other people, and finds it difficult to interact with others, preferring their own company instead.  The person with a suspicious personality disorder is often seen by others as strange or peculiar.

Emotional and impulsive personality disorders are where the sufferer is indifferent to other people’s feelings and can be quite aggressive.  They often find it difficult to control emotions and will do this spontaneously without thinking about the consequences.  Sufferers will also self harm if they feel really bad about themselves.

Anxious personality disorders are where the sufferer worries about everything.  They are very indecisive and worry constantly about doing the wrong thing.  Anxious sufferers are overly sensitive to criticism and can often feel worthless or incompetent.

There are therapies which can help such as psychotherapy or cognitive behavioral therapy.  There is also medication available to help with the different groups of personality disorders.  Antipsychotic drugs can help those in the suspicious group while antidepressants can help to relieve the symptoms of those in the emotional group.  There are also some antidepressants which have been shown to help those in the anxious group such as serotonin reuptake inhibitors (SSRI).
