When you overeat carbohydrates, your blood sugar rises, and insulin removes the sugar from the blood. Insulin also allows sugar to be used as fuel in the cell. Due to insulin resistance, many high blood sugar symptoms are related to low blood sugar and low sugar inside the cell.

Here are 7 high blood sugar warning signs.

1. Excessive urination

Waking up to urinate at night signifies a blood sugar problem and even a prediabetic situation. When you have too much sugar in the blood, it’s filtered by the kidneys and excreted in the urine.

2. Excessive thirst

Excessive urination leads to water loss and excessive thirst. High blood sugar causes sodium retention, which your body tries to dilute. High blood glucose also contributes to potassium deficiency, which also increases thirst.

3. Skin changes

Skin folds will often become darker due to excess glucose.

4. Brain fog and fatigue

Many people have no idea this is a symptom of high blood sugar! High blood sugar starves the neurons.

5. Mood swings

Irritability is often caused when your blood sugar that’s too high goes too low. A ketogenic diet can significantly improve mood issues.

6. Cravings

Cravings will typically be for sugar and salty carbs.

7. Blurry eyes

The lens of the eye becomes swollen, and the inside of the eye becomes reddened.

Fixing the diet and lowering carbohydrates could help eliminate symptoms of high blood sugar within weeks. You’ll also want to increase glucagon to decrease insulin by consuming high-quality protein like red meat, fish, or eggs.

An A1C test measures your blood sugar over 120 days. The higher the percentage of glycated hemoglobin you have, the more severe your diabetes is. If you’re on keto or the carnivore diet, you may notice that your A1C test is still high. This is because these diets extend the life of the red blood cells.
