Conditions

Encephalitis is an uncommon but serious condition in which the brain becomes inflamed (swollen).

Endocarditis is a rare and potentially fatal infection of the inner lining of the heart (the endocardium). It's most commonly caused by bacteria entering the blood and travelling to the heart.

Endometriosis is where cells similar to those in the lining of the womb (uterus) grow in other parts of the body. It can have a big impact on your life, but there are treatments that can help.

An enlarged prostate (sometimes called benign prostate enlargement) is when your prostate gets bigger. It's common and is not usually serious, but there are treatments that can help if you need them.

Epidermolysis bullosa (EB) is the name for a group of rare inherited skin disorders that cause the skin to become very fragile. Any trauma or friction to the skin can cause painful blisters.

Epididymitis is where a tube (the epididymis) behind the testicles becomes swollen and painful. It's often caused by an infection and is usually treated with antibiotics.

Epiglottitis is swelling of your epiglottis, the flap that covers your windpipe when you swallow. Epiglottitis can block your windpipe, even when you're not swallowing, making it difficult to breathe. It's a medical emergency and needs to be treated in hospital straight away.

Epilepsy is a condition that affects your brain and causes seizures (sometimes called fits). It cannot currently be cured, but treatment can often help manage it.

Erectile dysfunction (impotence) is very common, particularly in men over 40. It's usually nothing to worry about, but see a GP if it keeps happening.

Erythema multiforme is a skin condition that can be caused by an infection or some medicines. It usually gets better on its own in 2 to 4 weeks.
