What's the reason for high blood sugar in the morning?

This condition is called the dawn phenomenon. It can happen if you are a type 1 or type 2 diabetic, or if you have insulin resistance really bad.

Causes of elevated morning blood sugar:

1. Spike in Cortisol - Normally between 12 and 3 am, you have higher insulin sensitivity in the liver, so the blood sugar works a lot better. But, cortisol which mobilizes glucose for action and stress, peaks between 6 and 9 in the morning.

2. Type 1 diabetes – There’s a growth hormone spike that can mobilize the blood sugar.

3. Type 2 diabetes – The liver is making glucose called gluconeogenesis. Also, glucagon and epinephrine are hormones that can spike blood sugar. If you are a type 2 diabetic for a long period of time, you are eventually going to lose the ability to produce insulin.

4. Consuming a lot of carbs the night before. What to do if you have high blood sugar in the morning: • Give it time – Do the healthy ketogenic diet and intermittent fasting • Exercise • Avoid carbs – especially the night before • Take apple cider vinegar diluted with water the night before
