Eye Stye

What are eye styes?

In the eyelid, we have three types of sebaceous glands that are producing the liquid or oil from the eyes. Anatomically, usually develop in the glands of Zeiss or Moll, or are produced in the meibomian gland.

Meibomian glands (the major m) is secreted by the fat layer of the tear, which prevents evaporation and dry eye.

Allergy – How to Cope with It

An allergy is when the body reacts badly to a substance called an allergen. The body responds by discharging histamine and this can cause inflammation. This is why we often take medicines or use creams which contain an anti-histamine ingredient. Allergies provoke symptoms such as rashes or itchy skin or swelling. They can also cause coughing and difficulties breathing.

Allergies are very common – a person might only suffer for a short period, or they may be affected day in day out. Only in spring and summer is hayfever a problem for instance. And even within this some people are only affected by the allergens of trees – these are only around in spring – and others are only affected by grass pollen – these are summer problems.

Pets, detergents, medical products, foods… all these are potential allergens. In various people they might cause different conditions – asthma and eczema along with dermatitis are all triggered by allergens.
