Signs That You Have Too Much Sugar in Your Blood (Page 2 ) | August 23, 2025

High blood sugar, or hyperglycemia, can manifest through a variety of symptoms. These include frequent urination, increased thirst, blurred vision, fatigue, headaches, nausea, vomiting, shortness of breath, and abdominal pain. You may also notice fruity-smelling breath, dry mouth, and confusion—especially if hyperglycemia is left untreated.

Specific Symptoms to Watch For:

1. Frequent Urination and Excessive Thirst
High blood sugar causes the kidneys to work harder to eliminate excess glucose, leading to more urine production and, as a result, increased thirst.

2. Blurred Vision
Elevated glucose levels can affect the small blood vessels in the eyes, causing vision to become blurry.

3. Fatigue and Weakness
When the body can’t effectively use glucose for energy, you may experience constant tiredness and weakness.

4. Unexplained Weight Loss
In uncontrolled hyperglycemia, the body may start breaking down fat and muscle for energy, leading to noticeable weight loss.

5. Frequent Infections
High blood sugar weakens the immune system, making you more prone to infections such as urinary tract infections or yeast infections.

6. Slow-Healing Wounds
Excess glucose impairs the body’s ability to heal damaged tissue, causing cuts and sores to heal more slowly.

7. Tingling or Numbness in Hands and Feet
Diabetic neuropathy, a complication of diabetes, can damage nerves—especially in the extremities—causing tingling or numbness.

8. Nausea and Vomiting
When the body can’t use glucose, it starts producing ketones, which can lead to nausea and vomiting.

9. Rapid Breathing or Shortness of Breath
In diabetic ketoacidosis, a severe complication of high blood sugar, breathing may become rapid and shallow, and it may be difficult to breathe.
