Always feeling thirsty despite drinking plenty of water? Constant dry mouth might not just be a sign of dehydration; low potassium levels could also be a factor. Potassium plays a crucial role in maintaining fluid balance in your body. If you’re lacking this essential mineral, you might experience unusual dryness in your mouth. To address this, try adding more potassium-rich foods to your diet and consult with a healthcare provider if the issue persists. Increasing your potassium intake can help restore your body’s fluid balance and alleviate persistent dry mouth.
