    Summary
    This summary is machine-generated.

    Unexplained dizziness and lightheadedness are often linked to carbohydrate imbalance. Early identification via insulin glucose tolerance tests and dietary changes significantly improve patient symptoms.

    Area of Science:

    • Neurology
    • Endocrinology
    • Metabolic Disorders

    Background:

    • Unexplained vertigo and lightheadedness affect numerous patients.
    • Abnormal electroencephalography (ENG) and normal audiograms are common in these cases.
    • Potential links to metabolic dysfunction warrant investigation.

    Purpose of the Study:

    • To investigate the role of carbohydrate metabolism in patients with unexplained vertigo or lightheadedness.
    • To assess the utility of the insulin glucose tolerance test (IGTT) in diagnosing these conditions.
    • To evaluate the efficacy of dietary interventions for symptom improvement.

    Main Methods:

    • Fifty patients with unexplained vertigo or lightheadedness underwent evaluation.
    • All patients had abnormal ENGs and normal audiograms.

  • A five-hour insulin glucose tolerance test (IGTT) was performed, with insulin levels measured at multiple intervals.

    • Main Results:

    • 82% of patients exhibited borderline or abnormal insulin levels.
    • 90% of patients showed either an abnormal glucose tolerance test or borderline insulin levels.
    • Symptom improvement was observed in 90% of patients following a low carbohydrate diet.

    Conclusions:

    • Carbohydrate imbalance, identifiable by IGTT, is prevalent in patients with unexplained dizziness.
    • Early diagnosis of carbohydrate imbalance is crucial for managing dizzy patients.
    • Low carbohydrate diets are highly effective in alleviating symptoms.
