Non-specific urethritis

Complications of non-specific urethritis 

Reiter's syndrome

Reiter's syndrome - also known as reactive arthritis - is a uncommon complication of non-specific urethritis (NSU). An estimated 1% of NSU cases will result in the development of Reiter's syndrome.

Reiter's syndrome is caused by the immune system. For reasons that are not fully understood, the immune system begins to attack healthy tissue, rather than the bacteria that is responsible for NSU. This can cause symptoms of joint pain and conjunctivitis (inflammation of the eyes) as well as recurring symptoms of urethritis.

Immune system


The immune system is the body's defence system, which helps protect it from disease, bacteria and viruses.

Bacteria


Bacteria are tiny, single-celled organisms that live in the body. Some can cause illness and disease and some others are good for you.

Inflammation


Inflammation is the body's response to infection, irritation or injury, which causes redness, swelling, pain and sometimes a feeling of heat in the affected area.
