low blood sugar - General Health Message Board

I gave blood today and passed out due to low blood sugar. Are there any warning signs before you pass out due to low blood sugar? I felt fine during the donation and it was noted that my face went between flush and pale. 15 mins before I passed out I had my BP checked and it was high for me but not high in general. Is higher BP than what is regular to you a sign? And what about heart fluttering? My pulse was 84. Also while recovering from passing out my whole body felt very hot. Any advice would help and by the way I am thankful I was not sent to the ER.

Hi, Angel . . . I have hypoglycemia (low blood sugar). When my blood sugar starts getting low, I will feel weak, sometimes shake a little, often have a crawling sensation across the top of my head and even feel hot.

This triggers adrenaline which can make your heart rate and/or blood pressure change as well.

I am guessing the anxiety of having blood taken (I have situational anxiety as well), may have triggered your low blood sugar attack.

I would advise if you plan to give blood in the future that you eat a high protein meal (like low fat meat, cheese, or an egg or two) within an hour of giving blood. That should help stabilize everything for you.

Best of luck!
