Cystic fibrosis

Cystic fibrosis (CF) is an inherited disease which mainly affects your lungs and digestive system. It clogs up these organs with thick, sticky mucus which can lead to symptoms like a cough, chest infections and difficulty absorbing and digesting fat in food.


Epilepsy is a type of brain disorder treated at Great Ormond Street Hospital (GOSH) where your brain 'short circuits' so the electrical messages travelling to and from the brain are disrupted.

Food allergies

If you have a food allergy, you might not be able to eat certain things in case they cause an allergic reaction. Your body's immune system will react to a substance that is usually harmless, resulting in a number of chemicals being released into your bloodstream.

Growth hormone deficiency

Growth hormone deficiency (GHD) is a condition which slows down growth, or in some cases stops it completely. It develops when the pituitary gland – the gland which produces hormones and is located deep inside your brain – doesn’t produce enough hormones.


Haemophilia affects your body’s ability to control blood clotting, which is what is used to stop bleeding. It’s an inherited bleeding disorder, so if you have haemophilia it’s likely one of your relatives will have it as well.

Hirschsprung's disease

Hirschsprung’s disease is a rare disorder of the bowel, most commonly the large bowel (colon). It’s a life-long condition that affects your intestines and can lead to severe constipation. Hirschsprung’s disease can be treated at Great Ormond Street Hospital (GOSH) with surgery.
