Summary
Bariatric surgery can lead to serious neurological complications like axonal polyneuropathy, with most patients experiencing poor recovery. Patients must be informed about these risks before undergoing the popular procedure.
Area of Science:
- Neurology
- Bariatric Surgery
Background:
- Bariatric surgery is increasingly popular worldwide.
- Neurological complications following bariatric surgery are not well-documented in Brazil.
- Literature on this topic is scarce, necessitating case reporting.
Purpose of the Study:
- To report Brazilian cases of neurological complications after bariatric surgery.
- To highlight the range of neurological issues that can arise.
- To underscore the importance of patient awareness regarding potential risks.
Main Methods:
- Retrospective collection of neurological cases from eight Brazilian cities.
- Description of patient cases attended by neurologists.
- Analysis of reported neurological complications.
Main Results:
- Twenty-six cases of neurological complications were identified.
- Axonal polyneuropathy was the most common complication.
- Other identified complications included central demyelination, Wernicke syndrome, optical neuritis, radiculitis, meralgia paresthetica, and compressive neuropathies.
- Eighty percent of patients had partial or no recovery.
Conclusions:
- Bariatric surgery carries potential neurological risks.
- Neurological complications can be severe and may have poor outcomes.
- Informed consent is crucial, and patients must be aware of these risks before surgery.

01:22Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
