I’m going to be tested for diabetes and was told I have to drink a fruity drink and have to hang out for 2 hours. Just wondering, has anyone had side effects while waiting? Like fainting or throwing up?

My wife has type 1 diabetes. My son is 2 years old and does not have it (I hope). I have noticed a change in the way his breath smells, but there are no symptoms of diabetes .
He was at the zoo all day yesterday and only had one sippie cup even though he walked quite a bit . He took a nap on the way home, woke up, ate a plate of pasta and chugged three cups of milk. Then he threw up.
Out of paranoia, I tested his blood sugar, It was 189. I tested it again in an hour and it was 137. I tested it this morning and it was 91.

I have an appointment with the doctor tomorrow. My question is: can a child, or anyone, have a blood sugar of 189 if he is not diabetic / hypoglemic? Could the milk, pasta, and vomit make it go up in a healthy person?

Maybe I’m not doing it right?
It’s a blood glucose reading kit — it comes with needle device, strips and electronic reading device.
So, I prick the finger to bring blood, then I take a strip…..put it into the slot in the end of the reader, and put the blood on the part of the strip that’s sticking out. Then I wait for a reading, but either I don’t get a reading or the numbers (characters) are unreadable. Please, what am I doing wrong? Can someone spell out step by step what I should do…am I putting in the strips wrong,…..thanks

I’m 28 weeks with my first. No one in my family has diabetes, ( i know it can be hereditary).
I went for my 1 hour test. I got a call back from my docs office and they told me it was high, they are sending me to a 3 hour test tomorrow morning. I’ve gained 15 lbs so far but i was about 20 lbs over weight before getting pregnant.
could this be diabetes? If so, does it go away after the baby is born? What happens at birth? Any info will help. I just want my baby and I to be healthy. I heard the baby will be big. Does this mean my child will be overweight and hard for them to lose weight in their lifetime?
thanks

I am 30 weeks pregnant and I just found out I have gestational diabetes. Ohio Caresource will pay for the blood glucose meter and all supplies. However, I was wondering what type of meter they will pay for. Does anyone know? This is my first time using a glucose meter and I have to check my blood 4 times a day. I am looking for the least painful meter. – thanks.

I am referring to the 1-hour test. My score was 111 and I wonder what that means. Thanks.
