Factitious Disorder and Munchausen's Syndrome: Care Staff Guide to Fabricated or Induced Illness

Few situations are as hard for health and care staff as a suspicion that someone is pretending to be ill or making themselves, or someone in their care, unwell. The feelings it provokes, from disbelief to anger to worry, can cloud professional judgement. Yet the underlying problem is usually a serious psychological one, and where a child is involved it is a safeguarding matter. This guide, based on NHS information, explains factitious disorder (Munchausen's syndrome) and fabricated or induced illness (FII), and sets out how care staff should respond: calmly, without accusation and through the proper channels.

What is factitious disorder?

The NHS uses the term Munchausen's syndrome for a psychological condition in which a person pretends to be ill or deliberately produces symptoms of illness in themselves. Their main aim is to take on the sick role and be the centre of attention, rather than to gain practical benefits such as money or time off. This is what separates it from other behaviours: when the motive is financial or practical gain, a different explanation applies. Staff should be careful with labels. Only a qualified clinician can diagnose, and it should never be used casually or as a judgement about a person who is simply difficult to treat.

Signs the NHS describes

According to the NHS, a person with this condition might:

• claim psychological symptoms, such as hearing voices
• claim physical symptoms, such as chest pain
• deliberately try to become ill, for example by infecting a wound
• move between hospitals and leave suddenly when their story is questioned
• in serious cases, agree to painful or even life-threatening surgery that they know is unnecessary

None of these signs alone proves anything. Genuine illness can be hard to explain, symptoms can be real but medically unexplained, and people with severe distress or personality difficulties may behave in ways that look similar for different reasons. Our guide to borderline personality disorder is relevant because the NHS names personality disorders, including borderline, antisocial and narcissistic, among the factors that may be involved.

Why does it happen?

The NHS states that the causes are poorly understood. Suggested factors include emotional trauma in childhood or illness that involved extensive medical care, possible parental neglect or abandonment, personality disorders and a grudge against authority figures or healthcare professionals. In other words, the behaviour usually reflects deep emotional need, not simple dishonesty. Responding with contempt tends to push people away from help.

What staff should and should not do

Staff are not detectives, and it is not their role to investigate or confront. The NHS describes how clinicians approach a suspected case: they check health records for inconsistencies, test for self-inflicted illness or tampering with clinical tests, rule out other motives such as financial gain or wanting strong painkillers, and make a diagnosis only when there is clear evidence of fabrication, the main motive is to be seen as sick and no other explanation fits. For care workers, the practical points are:

• Record facts, not opinions. Write what you saw and heard, with dates and times, rather than "she is faking".
• Do not search belongings or confront the person. Raise your concerns with your manager or the responsible clinician instead.
• Take every symptom seriously until a clinician has assessed it. People with this condition can also become genuinely ill, and equally, someone whose symptoms seem odd may have a real condition.
• Keep communication consistent. Make sure the team shares the same information and approach.
• Protect the person's dignity and confidentiality. Do not discuss suspicions in front of others or with colleagues who do not need to know.

Treatment

The NHS explains that treatment is difficult because most people will not admit there is a problem. If they do, they can be referred to a psychiatrist. There is no standard treatment, although the NHS says psychoanalysis combined with cognitive behavioural therapy has shown some success, and family therapy may help if the person remains in close contact with family. The NHS notes that experts differ on whether a gentle, non-confrontational approach or direct confrontation is better. For care staff, that is a matter for the clinical team, not something to try independently. The NHS adds that if a person does not admit to lying, most experts agree that the doctor should minimise medical contact, because the doctor-patient relationship depends on trust. Decisions like this are clinical and should be made by the team.

Fabricated or induced illness in children

The NHS describes fabricated or induced illness (FII), formerly called Munchausen's syndrome by proxy, as a rare form of child abuse in which a parent or carer exaggerates or deliberately causes a child's symptoms. The carer may not intend to deceive doctors, but the child can still be harmed through unnecessary tests or treatment, false beliefs about being ill, or disrupted schooling.

The NHS lists signs including carers convincing clinicians that a healthy child is sick, lying about or exaggerating symptoms, tampering with test samples, or deliberately making the child ill, for example by giving unneeded medicine. It notes that wrongly reporting symptoms is far more common than inducing illness. The reasons are not fully understood: a carer may gain attention, support or closeness from the child's illness, or may hold anxious or mistaken beliefs about the child's health, and may not fully understand their own motives. The NHS links FII to conditions such as borderline personality disorder, self-harm and substance misuse. In a small number of cases the motive has been financial, such as claiming disability benefits.

Safeguarding: who to tell

The NHS is clear that FII is a child safeguarding issue that the NHS cannot manage alone. Its advice for staff who work with children is to tell their organisation's child safeguarding lead, or their supervisor if they do not know who that is. Clinicians who suspect FII liaise with social services and the police and follow local child protection procedures. Members of the public are advised not to confront the suspected carer directly, as this may lead to evidence being destroyed, and can contact local social services or the NSPCC helpline on 0808 800 5000 (open 10am to 4pm, Monday to Friday).

Our guide to safeguarding children for health and care staff explains how to recognise concerns and report them, and the principle applies equally if you work with adults: raise concerns with the safeguarding lead rather than acting alone. In regulated services, CQC Regulation 13 requires systems to prevent abuse and improper treatment, which includes acting on concerns promptly.

Outcomes for children and carers

According to the NHS, the priorities for the child are protection, establishing their true health and restoring them to good health through a health and education rehabilitation plan. Younger children often recover well once the abuse stops, while older children may need help understanding their real health and may feel loyal to, or guilty about, the carer. Treatment for the carer may involve intensive psychotherapy and family therapy, and the best outcomes occur when the carer acknowledges the harm and works with professionals. Whatever the outcome, the child's welfare comes first.

Looking after yourself

Situations like these are emotionally taxing. Use supervision and debriefs, avoid carrying concerns alone, and remember that your role is to report and record, not to prove. Maintaining professional boundaries helps you stay fair and compassionate.

Frequently asked questions

Is factitious disorder the same as malingering?

No. The NHS says people with Munchausen's syndrome are motivated by the wish to be seen as ill and to receive attention, not by practical benefits such as money, which is what separates it from other behaviours.

What should I do if I suspect fabricated or induced illness in a child?

Tell your organisation's child safeguarding lead, or your supervisor if you do not know who that is, as the NHS advises. Do not confront the carer.

Can people with factitious disorder recover?

The NHS says treatment is difficult because most people do not admit the problem, but some benefit from psychological therapy if they engage with it.
