Acne

Lots of teenagers experience acne. It’s a very common skin condition among 12 to 15 year olds. It affects the hair follicles in your skin, mainly on your face, chest and back.

Arrhythmias

Arrhythmias are abnormal heart rhythms, which can prevent the heart pumping efficiently. This page from Great Ormond Street Hospital (GOSH) explains how the heart beats normally, what happens when it starts to beat abnormally and how it can be treated.

Arthritis

Arthritis is a painful condition that affects the joints and bones, and can make it difficult for you to move around. You might think it just affects older people, but young people can experience it too. The tissue lining the joints, like elbows and knuckles, becomes inflamed, making them stiff and swollen.

Birthmarks

A birthmark is a coloured area of skin. Some people are born with birthmarks (as the name suggests), but they can also appear in the weeks after you’re born. Many people have a birthmark of some kind but very few need treatment for them. Certain types of vascular birthmarks can be treated at Great Ormond Street Hospital (GOSH) with laser surgery.
