6. Constant tiredness and fatigue

Fatigue occurs when a person has either high or low blood sugar. If the blood sugar is too high but it can't enter cells, the person will feel groggy and lethargic. If blood sugar is low, fatigue is also common. Hunger can also contribute to additional fatigue. People who do not drink enough fluids will feel more dehydrated and tired. Constant fatigue and tiredness alone do not usually indicate diabetes -- rather, these symptoms will occur along with others. Blood glucose testing can indicate whether high or low blood sugar is the cause of a patient's fatigue.
