Hello, My Name Is Caleb , I Am A Type

hello, my name is caleb , I am a type 1 diabetic , I have had tis since I was 5 and I am 27 . recently I have had a few episodes of low blood sugar, followed by vomiting. I do not necessarily feel like I am sick(flu) and do not think it is food poisoning considering several people have ate what I have and they appear to be fine...I was recently sick with a bronchitis and have had excess drainage the past few days... could the drainage in combo with the low blood sugar cause me to vomit? thank you
