Sometimes blood sugar can be high without obvious symptoms, which is why regular checkups are important—especially for people at higher risk.
Here are 12 possible warning signs that may occur when blood sugar levels are elevated:
1. Increased Thirst
Excess glucose in the blood can cause the body to pull more water from tissues, leading to frequent thirst.
2. Frequent Urination
The kidneys may try to remove extra glucose through urine, causing more trips to the bathroom, especially at night.
