People with factitious disorder crave the attention of doctors and other medical professionals, and they will invent imaginary conditions to get it, or induce actual illnesses or injuries to guarantee it. The sympathy and compassionate care they receive when they are ill, injured, or suffering from a chronic disorder brings them enormous satisfaction.
Because they so frequently seek medical attention, people with factitious disorder may become addicted to prescription drugs, leading to a dangerous overlap of factitious disorder and addiction that requires comprehensive treatment. They may even use drugs or alcohol to intentionally to make themselves ill, and that behavior can also lead to drug or alcohol dependency.
Another factor is the stress that inevitably accompanies a lifestyle based on deception and manipulation. Plagued by anxiety, shame, and low self-esteem, people with factitious disorder may use and abuse drugs and alcohol to make themselves feel better. Or, in some instances the co-occurrence of factitious disorder and addiction may be entirely coincidental, emerging from shared risk factors that leave people vulnerable to both. Many residential treatment centers, including dual diagnosis programs, provide specialized care for factitious disorder and drug addiction together
