Signs and symptoms of Munchausen's syndrome may include pretending to be ill or self-harming to aggravate or induce illness.
There are 4 main ways people with Munchausen's syndrome fake or induce illnesses, including:
lying about symptoms – for example, choosing symptoms that are difficult to disprove, such as having a severe headache or pretending to have a seizure or to pass out
tampering with test results – for example, heating a thermometer to suggest a fever or adding blood to a urine sample
self-infliction – for example, cutting or burning themselves, poisoning themselves with drugs, or eating food contaminated with bacteria
aggravating conditions – for example, rubbing faeces (poo) into wounds to cause an infection, or reopening previously healed wounds
Coming across this for the first time. Thanks for sharing.
