There are discussions here you can search about lows & how low some of us have been.
Understand feeling sad & frustrated. It can be very scary. I hate the feeling that accompanies lows.
Yes, sadly, severe hypoglycemia can kill, but not at 50-60. You’re not taking it too seriously. Correcting lows & trying to stay at a target is important because being low often can result in hypoglycemic awareness. The body adjusts so you’re not aware of the drop.
There are things you can do, so please don’t worry.
First off, you need to know your ratio to correct highs so you don’t drop like a stone. In other words, you need to learn how many units of insulin lowers BG by how many points. Everyone is different, but there are general guidelines of 40-60 pts per 1 unit of insulin. By starting out conservatively & testing, you can can find what works for you.
How much insulin do you take to correct 400? Sorry, but also have to ask how often you’re as high as 400? Your doses of matching food to insulin aren’t right if you’re at 400. You can learn your insulin:carb ratio to prevent the highs to begin with. We all have highs & lows.
Along with knowing this, understanding how much glucose to take to fix a low is important so that you don’t over do it. Tempting to chug sugar. Again, everyone is unique. I’m super sensitive & I’m small. Just 1 gram glucose raises me 10 pts. Took a lot of testing to figure this out. It can take up to an 1 hour to see the full effects. Really hard to be patient waiting for this when we’re told the 15 minute rule.
It can be terribly overwhelming & confusing. Get the books Think Like a Pancreas & Using Insulin. They’re wonderful & will really help. Keep logs of your doses & readings to discuss with your doctor to adjust your doses.
