Patient perceptions of self-induced water intoxication

Area of Science:

• Psychiatry
• Clinical Psychology
• Internal Medicine

Background:

• Self-induced water intoxication (SIWI) is a serious condition often observed in individuals with serious mental illness (SMI).
• Understanding the patient's perspective on SIWI is crucial for developing effective interventions.

Purpose of the Study:

• To comprehensively examine SIWI from the patient's perspective, including demographics, motivations for fluid seeking, behavioral patterns, and experienced symptoms.
• To explore the underlying psychological factors contributing to SIWI in a hospitalized SMI population.

Main Methods:

• A structured interview using the Self-induced Water Intoxication Questionnaire (SIWIQ) was administered to 45 individuals with SMI hospitalized in a long-term psychiatric facility.
• The study analyzed demographics, fluid-seeking behaviors (e.g., drinking from showers, toilets, urine), and self-reported symptoms (e.g., anger, vomiting, anxiety, cognitive difficulties).

Main Results:

• SIWI was more prevalent in males and individuals with longer hospital stays; most participants were smokers with no history of alcohol problems.
• Anger, vomiting, anxiety, and cognitive difficulties were predominant symptoms. Reasons for excess fluid consumption included anxiety, boredom, seeking a 'high,' and sad mood.
• Drinking from unconventional sources like showers and toilets highlights the challenges in fluid management.

Conclusions:

• SIWI may represent a dysfunctional coping strategy aimed at alleviating anxiety and boredom.
• Interventions should adopt a multifaceted approach, considering psychological and behavioral factors beyond simple fluid restriction.
• Further research is needed to explore the complex interplay of factors contributing to SIWI in SMI patients.
