Özet

Obsessive-compulsive disorder (OCD) is characterized by intrusive, recurrent thoughts (obsessions)

that cause marked anxiety and by repetitive behaviors (compulsions) performed to reduce this

anxiety. Contamination and hygiene-related obsessions are among the most common subtypes.

When these obsessions involve food, they may lead to severe dietary restrictions, medical

complications, and social isolation. We present the case of a 67-year-old woman with lifelong food

hygiene-related obsessions dating back to childhood. She believed that food was “dirty,” that each

item had to be washed individually and, if necessary, soaked in vinegar, and that others could not

prepare meals hygienically. Consequently, she avoided eating in restaurants or cafes, refrained from

ordering food from outside, refused hospital meals, and arranged for food from her home during

hospital stays. She was hospitalized in the endocrinology department for hyperglycemia and referred

to psychiatry for hyperphagia assessment. Observations by the treatment team and other caregivers

prompted a detailed history, revealing persistent obsessive thoughts and compulsive behaviors. Due

to limited insight, she considered these behaviors normal and had never sought psychiatric care.

Fluoxetine 20 mg/day was initiated, psychoeducation provided, and follow-up arranged. Literature

shows that diagnosis in food hygiene-related OCD is often delayed, may be mistaken for other

conditions, and can result in serious complications from dietary restriction. This case underscores

that in patients with limited insight, thorough history-taking, attentive observation, and a

multidisciplinary approach are essential for timely diagnosis and for preventing physical health

deterioration, complications, and social isolation.
