Do you wake up exhausted? If you feel drained, even after a good night’s sleep, it is a red flag. People often dismiss this sign as general tiredness. Persistent fatigue and lack of energy, especially in the morning, could be due to the body’s inability to use glucose for energy. Elevated blood sugar levels at night can also disrupt energy metabolism, because in people with prediabetes, the cells resist insulin, leaving glucose unused. This could lead to lethargy that is especially worse in the morning.
