A wart is a common type of skin growth that can occur singly or in clusters. They are most common on the hands, but can develop elsewhere on the body such as the feet. Warts are not usually painful, unless they are on the soles of the feet. They are contagious however, so can spread to other parts of the body or even to other people.
Anaemia is a very common condition where the number of red blood cells or the amount of haemoglobin in red blood cells is less than normal. Iron deficiency anaemia is a specific type of anaemia caused by a lack of the mineral iron in the body. Iron is important in the formation of haemoglobin so a reduced iron level causes a reduced haemoglobin level in the blood.
A stye (hordoleum) is an inflamed area of the eyelid, either at the base of an eyelash (external hordoleum) or on the inside surface of the eyelid (internal hordoleum). Styes are more common in children than adults.
A chalazion is a cyst (swollen area of tissue filled with fluid) that develops on the eyelid. The cyst is not usually painful, but can take a while to go down. Only very large chalazions can affect vision, by pressing on the eye.
Food intolerance is a type of food hypersensitivity that is very different to food allergy. Food allergy and food intolerance are often confused. A food allergy provokes a response from the immune system, but food intolerance does not.
