Here are the most commonly overlooked symptoms, broken into high vs. low blood sugar.
🔴 Warning Signs of High Blood Sugar (Hyperglycemia)
(Often missed or assumed to be “just tired”)
1. Constant thirst (polydipsia)
Feeling thirsty all the time—even after drinking water.
2. Frequent urination
Especially waking up at night to pee (nocturia).
3. Increased fatigue
Blood sugar can’t enter cells efficiently → low energy despite eating.
4. Blurry vision
High sugar temporarily alters the fluid balance in your eyes.
5. Slow healing cuts or wounds
Sugar impairs circulation and immune response.
6. Frequent infections
Yeast, skin infections, UTIs, gum infections become more common.
7. Tingling or numbness in hands/feet
Early nerve irritation from elevated glucose.
8. Unexplained weight loss
The body breaks down fat/muscle when it can’t use sugar properly.
9. Increased hunger
Cells “starved” of usable glucose trigger cravings.
🔵 Warning Signs of Low Blood Sugar (Hypoglycemia)
(Often mistaken for anxiety or stress)
1. Shakiness or trembling
Body releases adrenaline to raise blood sugar.
2. Sudden sweating
Cold, clammy skin is a key early sign.
3. Rapid heartbeat
4. Irritability or mood changes
Low sugar affects brain function quickly.
5. Dizziness or lightheadedness
6. Difficulty concentrating or confusion
7. Blurred vision
8. Weakness or fatigue
9. Headache
⚠️ When Abnormal Blood Sugar Becomes Dangerous
Seek immediate care if there are:
-
Severe confusion
-
Trouble speaking
-
Vomiting
-
Fruity-smelling breath (sign of very high sugar)
-
Seizures
-
Fainting
These can signal diabetic ketoacidosis (very high sugar) or severe hypoglycemia.
🟢 What to Do if You Suspect Abnormal Blood Sugar
-
Check your glucose if you have access to a meter.
-
Monitor patterns—symptoms after eating vs. skipping meals.
-
Stay hydrated.
-
Avoid extremely sugary foods until evaluated.
-
See a healthcare provider for:
-
A1C test
-
Fasting glucose
-
Oral glucose tolerance test
-
Early recognition and treatment can prevent serious long-term complications.
