KEY TAKEAWAYS:

B1/Thiamine deficiency can lead to Wernicke’s encephalopathy, a severe neurological condition, particularly in bariatric patients post-surgery due to reduced nutrient intake.
Preventive care through B1/Thiamine supplementation (100 mg daily) starting two weeks before bariatric surgery and continuing for three months post-op is critical to avoid complications.
Patient education on bariatric nutrition, especially the importance of vitamin B1, empowers individuals to advocate for their health and prevent malnutrition risks.
