Check out these 15 symptoms of high blood sugar that might occur while you’re sleeping.

1. Frequent urinating

This is known as nocturia and occurs when your kidneys remove excess sugar from your blood.

2. Excessive thirst

As your kidneys eliminate sugar through your urine, you deplete magnesium, potassium, and calcium. You can also become dehydrated, so you may have excessive thirst.

3. Restless legs syndrome

Excess sugar depletes vitamin B1. Vitamin B1 deficiency causes lactic acid buildup and a lack of oxygen in the legs. This can also be related to magnesium deficiency.

4. Peripheral neuropathy

This condition causes burning, pain, or numbness on the bottom of the feet. Benfotiamine combined with alpha lipoic acid is a great remedy.

5. Cramps in lower legs and feet

Too much sugar in the blood can cause a magnesium deficiency and calcium buildup. Magnesium glycinate supplements can help, and can also improve sleep.

6. Excessive sweating

This usually occurs in the face, neck, or upper part of the body. High blood sugar causes sympathetic dominance, which causes a person to be in a constant state of fight or flight.

7. Sleep apnea

This usually occurs because a person has high levels of insulin.

8. Hypoglycemia

If you have high blood sugar, your body will try to lower it with insulin. This can cause you to wake up during the night with low blood sugar. Following a low-carb diet for at least 6 to 8 months can help correct this problem.

9. Delayed sleep

High levels of sugar delay the release of melatonin.

10. Gastric reflux

High blood sugar can affect the autonomic nervous system that controls the valve on the top of the stomach, causing GERD.

11. Nightmares/vivid dreams

This is typically related to a neurotransmitter problem caused by a deficiency in vitamin B1, which is depleted by high blood sugar.

12. High blood pressure

Nocturnal dipping occurs when your blood pressure and pulse rate decrease during sleep. When you have diabetes, this doesn’t happen. This is called non-dipping.

13. Heart palpitations

This is caused by a lack of potassium and magnesium and can be corrected with a good electrolyte powder.

14. Teeth grinding

The activation of the sympathetic nervous system puts a person into a state of stress while they’re sleeping, causing teeth grinding.

15. Headache upon waking

This usually occurs because of dehydration.
