Feeling drunk without drinking can be caused by several medical or physiological conditions. Common reasons include low blood sugar (hypoglycemia), where the brain lacks adequate fuel leading to confusion, dizziness, and impaired coordination similar to intoxication. Other causes include inner ear disorders, medication side effects, neurological problems, or a rare condition called Auto-Brewery Syndrome. Auto-Brewery Syndrome occurs when yeast in the gut ferments carbohydrates into alcohol, causing the body to produce ethanol internally and leading to symptoms of intoxication without drinking any alcohol. This syndrome is rare but can cause serious symptoms like dizziness, confusion, slurred speech, and fatigue. Other possible causes are metabolic imbalances or psychological conditions affecting perception and cognition. If this feeling is persistent or severe, it is important to seek medical evaluation to identify the underlying cause and receive appropriate treatment.
