Purpose:
To describe a case report of a patient with symptoms associated with metabolic alterations 1 month after having COVID-19.
Methods:
Laboratory tests, clinical evaluations, and body composition assessments were performed by specialists.
Findings:
The patient presented excessive sweating, hot flashes, dizziness, blurred vision, and seizure. Laboratory tests indicated low glucose levels after convulsions (50, 42.7, and 55 mg/dL), high insulin levels (basal, 638 µIU/mL; 2-hour, >1000 µU/mL), and positivity for anti-insulin antibodies. The patient was diagnosed with insulin autoimmune syndrome. Treatment with azathioprine and nutritional recommendations improved remission.
Implications:
SARS-CoV-2 infection or vaccination might induce insulin tolerance failure.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
