How long can a type 1 diabetic last without insulin injection?

It depends.: If relatively healthy and you have a ready supply of fluids to drink, you can get along but will be progressively losing weight and be hounded by insatiable thirst and frequent urination night and day.

After taking long term insulin why did my bs drop 50 points in 5 minutes?

Can recheck: If one is using Insulin and notices a sudden change in the blood glucose reading, she can double check the Insulin to make sure the dose is correct, and then retest the blood sugar. Sometimes, a blood sugar result is not correct, due to reasons such as machine error, problems with the test strip, human error, etc...

Is there any connection between Prozac and diabetes? After being put on prozac, diabetes type II went out of control to the high side and it is still out of control even after switching to insulin (both long and short acting). Is there any connection betw

I : I am unaware of any clear association between Prozac and diabetes. Depression is more common in those with diabetes so anti-depressants are frequently prescribed for people with diabetes. Prozac tends to not cause weight gain. If you are convinced the Prozac increased your sugar (not at all likely) you can discuss stopping it and using a different anti-depressant. Some people get more motivated to test their sugar when their depression is better. I wonder if you are just testing your sugar more. If your a1c (the 3 month test of sugar control) went up a lot after the Prozac as compared to before the Prozac and you had no weight gain, that would suggest the Prozac did it. Discuss that with your doctor. See my blog post on exercise and depression and how to use Insulin below. Your doctor may benefit from reading the Insulin post. ...Read more
