The Neurological Impact of Metabolic and Bariatric Surgery: A Systematic Review of Post-Operative Neuropathic and Non-Neuropathic Complications.

In 30 seconds

This systematic review evaluated neurological complications following metabolic and bariatric surgery in over 5000 patients. The incidence of such complications ranged from 1.4% to 16%, with peripheral neuropathy being the most common. The review highlights the importance of nutritional management, particularly thiamine supplementation, to mitigate these risks.

Key findings

• Incidence of neurological complications post-surgery ranged from 1.4% to 16%.
• Peripheral neuropathy was the most frequently reported complication.
• Thiamine deficiency was identified as the predominant cause of neurological issues.
• Severe or delayed complications were linked to persistent deficits and occasional mortality.

Why it matters

Understanding the spectrum of neurological complications associated with bariatric surgery is crucial for clinicians. Awareness of these risks can guide post-operative care and nutritional management, ultimately improving patient outcomes and reducing long-term neurological harm.
