Blооd ѕugаr can skyrocket, еѕресiаllу in реорlе whо hаvе рrеdiаbеtеѕ оr diаbеtеѕ. Yоu mау fееl a ѕugаr high, оr burѕt of еnеrgу, within minutеѕ tо аn hоur оf еаting.

I know that low blood sugar levels can also cause a variety of problems within our central nervous system. Some of my early symptoms included weakness, lightheadedness, and dizziness. I would like to also point out that headaches were often. I am taking care of my diet now. And after about a month eating healthier, I have felt much better.
Hey Abel,
Yes low blood sugar levels can cause many problems in your entire body.
These low levels can also be very dangerous if you’re not careful, even more so than high blood sugar levels.
And yes the symptoms you described are typical of having low blood sugar levels after you eat.
Yes doesn’t everything always comes down to taking care of your diet and exercise?
Let’s all keep an eye on your sugar levels especially if they happen to be low and after eating.
Thanks for sharing! I appreciate it 🙂
Lots of good information here. Diabetes is such a big issue in today’s society. I definitely learned a lot from your article. Having a family member with type 2 diabetes, knowing the signs of low blood sugar can literally save their life, so I thank you for putting it all in one post.
Hi! Yes there is plenty of good information here.
It’s always important to know whether your blood sugar levels are low or not.
Because the fact is that low blood sugar levels are more dangerous than high blood sugar levels.
So it’s important to know the reason why your blood sugar levels are high or low for that matter.
And it absolutely can save your life knowing why your blood sugar levels are low especially after eating.
I appreciate your comments. Thank you so much 🙂
