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

Hay fever can be described as an allergy caused by pollen. Pollen is the very fine powdery substance created by plants for the use in pollination, or fertilization. In its most common guise, hay fever is the allergy caused by grass or hay pollens and usually occurs from late spring until early summer.

Usual symptoms of the condition include a runny nose, sneezing, and streaming, itchy eyes. The symptoms are caused due to the body’s immune system reacting to the pollen. Cells which line the nose and eyes tend to release chemicals such as histamines when they come into contact with the pollen, and this causes the inflammation in the eyes and nose which produce the symptoms.

Hay Fever

Hay fever is a very common allergy and affects almost two in every ten people in western society. It usually develops in children of school age and teenage years and the symptoms reappear year after year. Eventually, the symptoms start to decrease over the course of many years, until the condition either disappears totally, or improves vastly. The condition usually runs in families and an individual is more likely to develop asthma or eczema if they already suffer from hay fever.

Although it’s impossible to avoid pollen totally, symptoms are less severe if exposure is reduced. Nowadays pollen counts are freely available for all regions via TV, radio and the internet. Sufferers of the condition are normally treated with antihistamine tablets, antihistamine nose sprays, steroidal nose sprays and eye drops.

Syphilis is most often a sexually transmitted disease, although it can be passed on through injecting drugs into a vein, from an infected pregnant woman to the unborn infant (congenital syphilis), or through blood transfusions.  It cannot be passed through casual person to person contact, i.e. touching, sharing toilet facilities or sharing things such as cutlery, etc.

Syphilis can be quite dangerous as it can lie in the body undetected and then resurface many years later affecting organs such as the eyes, brain, heart or nervous system.

Syphilis

Primary syphilis starts with painless sores on the skin which are very contagious.  These sores are known as chancres and can if another person comes into contact with these typically during sexual contact, then they will more than likely contract the syphilis infection.

Typically, between two to ten weeks later, more symptoms will appear and this is known as secondary syphilis.  These symptoms include tiredness, headaches, sore throat and skin rashes.  These symptoms will then disappear but the infection can lie dormant for many years and can then return causing organ damage and even organ failure.

Primary syphilis can be quite mild and therefore the patient may not know they even have the disease before passing it on.  It can be treated with antibiotics.

Abstaining from sex is the only definite way to avoid catching the syphilis infection.  However condoms do offer protection.  Sex toys should never be shared.
