Conditions

Giardiasis is a tummy bug that causes symptoms like diarrhoea, farting and bloating. It usually goes away in about a week if it's treated, but it can sometimes last much longer.

Gilbert's syndrome is a common genetic condition that may cause mild jaundice (yellowing of the skin and whites of the eyes) that comes and goes. It does not usually need any treatment.

Glandular fever is a viral infection that mostly affects teenagers and young adults. It gets better without treatment, but it can last for weeks and make you feel very ill.

Glaucoma is an eye condition where the main nerve, which connects the eye to the brain, becomes damaged. It's most common in adults aged 50 and over and can cause vision loss if it's not diagnosed and treated early.

Glomerulonephritis is damage to the tiny filters inside your kidneys (the glomeruli). It's often caused by your immune system attacking healthy body tissue.

Glue ear is where the middle part of the ear canal fills up with fluid. This can cause temporary hearing loss. It usually clears up within 3 months, but see a GP about any hearing problems.

A goitre is a lump or swelling at the front of the neck caused by a swollen thyroid. The thyroid is a small gland in your neck that makes hormones. Goitres are not usually serious but should be checked by a GP.

Gonorrhoea is a sexually transmitted infection (STI) passed on through unprotected sex (sex without a condom). It's treated with antibiotics. If it's not treated, it can cause serious health problems.

Gout is a type of arthritis that causes sudden, severe joint pain. Painkillers can help the pain and healthier lifestyle choices can prevent future attacks.

Granuloma annulare is a skin condition that often looks like a ring of bumps. It sometimes clears up without treatment, but it can take a long time and it may come back. See a GP if you have bumps or lumps on your skin that do not go away in a few weeks.
