“A little high is better than an ambulance or hearse ride.”
I treat most lows pre-preemptively by predicting them and seeing them coming. I get less than one per month that I didn’t see coming, but still soon enough to self-treat. That’s with MDI and old- fashioned synthetic human insulin . I actually did worse using the latest analog insulins.
If you are experiencing lows often enough to be concerned about them, then you are taking too much insulin and/or taking it at the wrong times. With Humalog you can get fast acting good or bad results. You are also likely to be over-treating your lows.
There’s no excuse for overtreating lows using the generic 15/15 rule for 150 lb male strangers. Your carb to BG correction factor is the same as your insulin to BG correction factor. It just has the opposite effect.
To use insulin safely, you need to have accurate information. You must know your insulin to carb ratio(s) and your correction factor You must be conscious of what you eat, do a reasonably good job of counting carbs, and if you are uncertain about an unusual food, meter and intentionally under-bolus before, meter an hour to two after, and correct. Being high for an hour is safer than being low.
If you do these things you will reduce your lows. Preventing then os harder than it sounds in the books because humans are not machines. The need for insulin is not just dependent on food. Activity, and amount and quality of sleep changes the need. Varying hormones change it more. If you have a low one day the chance of your having one the next day are higher because you will deplete the stress response hormones that produce the warning symptoms. (Prolonged stress has the same effect; people without diabetes under extreme stress make mistakes more frequently because they experience the same symptoms (irritability, slower reactions, decreased awareness, fuzzy thinking, etc.)
Children, young adults and all women all have responses to insulin that can vary considerably form day to day due to growth and other hormones.
A person with “brittle” diabetes actually suffers from a lack of the right information about their body at the right time. Combine this with with a variable schedule, variable diet, variable sleep and variable activity and it’s nearly impossible to control your blood sugar unless you are a walking computer like Mr Spock or Sherlock Holmes.
If you are brittle, you ought to be seeing a professional and wearing a CGM
Keeping accurate* food, activity, and sleep logs for at least a month to get in tune with your body’s needs. Most people, not just women, have a monthly cycle. If you can identify yours and see the pattern of your uncontrollable changes, you can combine that with your controllable behavior to get a better grip on your lows.
*Accurate food logs have grams of carbohydrates based on weighing portions on a scale. The larger fast food chain restaurants should be able to give you a nutrition guide that lists carbs for their menu items. (imo, None of them have menus suitable for chronic eating, just emergencies and travel.)
