5 Causes of High Blood Sugar

You have diabetes so it is very important to keep your blood sugar levels within a good range. Poor control of blood sugar levels over time can lead to heart disease, kidney failure, nerve damage and eye problems.

What are the causes of high blood sugar levels?

Do you know what causes your blood sugar levels to spike?? When I was first diagnosed with diabetes I tested so often to get an idea of what causes my blood glucose to spike. Some things surprised me, others did not but it was a great study to know for myself what causes those annoying spikes. Here are 5 causes you may or may not know.

1. Artificial sweeteners

You may ask Why? Well with sweeteners they can still have lot’s of carbs from starches. Be on the lookout for total carbohydrates on the label before you partake. Also look for those sugar alcohols. Xylitol and sorbitol can still cause your blood levels to spike. Yes they add sweetness with fewer carbs but that does not mean they are without carbohydrates so they could have just enough raise your levels.

2. Caffeine

That’s right your morning cup of joe could hinder your glucose levels and put a spike in your meter reading. Energy drinks and caffeine filled beverages are what you have to be aware of. You can do your own testing to figure out if caffeine is an issue for you. If you find spiked blood glucose then you may want to give it up all together or at least cut back.

3. The dawn phenomenon

What is the “dawn phenomenon” you ask? It is a surge in hormones that happens daily in the very early morning hours before you even wake. The rise in glucose is because of the body making less insulin and more glucagon a hormone that can increase your blood glucose. If you tend to have morning readings that are high you may want to discuss with your doctor or diabetes educators so you can better identify the problem and take some steps to correct it.

4. A bad night sleep

Even one bad night sleep can throw your blood glucose off. Sleep is restorative and our bodies need sleep to restore our bodies and not getting enough sleep can spell out chronic stress on our body. Our body will react and even raise our blood glucose if we are not getting the right amount of sleep. If you’re not getting proper sleep and it has become a problem for you bring it up with your doctor or diabetes educator and they can discuss what you can do to help in getting more sleep.

5. Having a bad cold

Most important is to make sure you stay hydrated. Drink, drink and drink more. Water and others fluids that help keep you stay hydrated. Make sure you make a doctor visit if you have had diarrhea or vomiting for more than a few hours or if you have been sick and are not feeling any better by the third day. Make sure to be aware that there are medications out there such as decongestants that can help with clearing your sinus but can affect your blood sugar. You may want to test more often while on medication so you can see how it affects your body.

Taking control over your own blood sugar is empowering. Not always will we know exactly what is going to make our sugar levels spike but studying your own body and getting to know what and what does not cause spikes is a great way to live.

    I always like your articles!! Where have I been I did not know that having a cold would give me reason to worry about my blood sugars. Now I will be a little more forgiving if it’s high when I am sick. Good to know. Thank you!
