I Have Not Been Regular In A Few Weeks And

I have not Been regular in a few weeks and think this is why some days I just generally feel not right. Also hot flashes make me feel sorta sick right before I have one. I’m also diabetic and when I feel weak or faint my sugar is around 80 and I don’t think that is low. Can constipation make for these type of feeling? I think I’m the past it has but it’s going on for too long this time. And it’s not every day. I felt normal for about a week and yesterday I was pretty good. It’s all very confusing
