High blood sugar, or hyperglycemia, can be dangerous if not recognized early. Here are 14 common symptoms that may indicate very high blood sugar levels:
1. Frequent urination (polyuria)
High sugar levels force your kidneys to work harder, leading to increased urination.
2. Excessive thirst (polydipsia)
The body tries to replace fluids lost through frequent urination.
3. Unexplained weight loss
Despite eating normally, the body starts breaking down fat and muscle for energy.
4. Extreme hunger (polyphagia)
Cells aren’t getting enough glucose, triggering intense hunger.
5. Fatigue
High sugar levels prevent cells from properly using glucose, leaving you tired.
6. Blurred vision
Fluid shifts in the eyes can affect lens shape, causing temporary blurred vision.
7. Slow-healing wounds
High sugar can impair circulation and immune response, slowing healing.
8. Recurrent infections
More susceptible to skin, urinary, and yeast infections.
9. Dry mouth and itchy skin
Dehydration from urination and poor circulation can cause dryness and itching.
10. Nausea or vomiting
Can indicate that blood sugar is extremely high, sometimes progressing toward diabetic ketoacidosis (DKA).
11. Shortness of breath
Occurs if the body starts producing ketones (sign of DKA).
12. Fruity-smelling breath
A sign of ketone buildup, common in type 1 diabetes emergencies.
13. Confusion or difficulty concentrating
High blood sugar affects brain function, leading to mental fog or disorientation.
14. Headaches
Often caused by dehydration and shifts in blood sugar levels.
⚠️ Important: Very high blood sugar can become a medical emergency, especially if you notice nausea, vomiting, fruity breath, or confusion. If any of these appear, seek medical attention immediately.
