Can diabetes make you sleepy?

I often feel incredibly tired and sleepy, even after a full night's rest. I've been diagnosed with diabetes. Can diabetes make a person feel excessively sleepy and fatigued?

Yes, high sugar levels can make your blood thick and slow down circulation, which makes you feel very sleepy and tired after meals. I manage this by eating low-carb, high-fiber food and strictly checking my sugar levels post-lunch.

I have seen this question many times in our group, and the answer is yes. Both high and low sugar can cause extreme drowsiness. Keep a diary of when you feel most sleepy and share it with your doctor during your next visit.

I used to feel so guilty and lazy because I was constantly sleepy, and it really took a toll on my mental health. Please don't blame yourself, it is just your blood sugar acting up. Once your levels stabilize, your energy will return.

In my experience, whenever my sugar shoots past 250, I cannot keep my eyes open and just have to take a nap. Once my doctor adjusted my afternoon insulin dose, this sleepiness reduced a lot.

Yes, sleepiness is very common when sugar levels are high. Avoid heavy carbohydrate dinners, try to drink more water to flush out excess sugar, and make sure you do a 15-minute walk after your meals.

Actually yaar, post-lunch sleepiness is so real when you have diabetes. If I eat heavy rice, I am completely knocked out for two hours. Switching to quinoa or multigrain chapati really helped me stay awake.

At least you have a medical excuse to sleep during boring office meetings now! Jokes apart, it is usually just your sugar levels fluctuating. Get a quick blood test done and consult your doctor to fix your energy levels.

Feeling sleepy usually means your body is struggling to convert glucose into energy. If your doctor allows, doing a brisk 20-minute walk after meals is the best way to lower your sugar spikes and beat that sluggish feeling.
