Alcohol Abuse
When alcohol is consumed in large amounts routinely, nausea is often a result, and that might lead to vomiting. Alcohol will affect potassium levels in other ways, too. Since alcohol dehydrates, it will cause imbalances in your electrolytes—the conductive ions within the body’s fluids—and that affects your potassium levels.
This is one of the reasons a common hangover cure is eating a banana or other foods high in potassium. However, you should also limit your alcohol intake to avoid damaging your system too much.
