Insulin setting time

I need to know when the fast insulin must be put, I have read that if you put it immediately you do not have the same effect as if you put it 15 or 20 minutes before, that is, that it covers or not the carbohydrates we eat.Someone can explain it to me

Hi @"Cristóbal Castro Martínez"!

Very good question, and surely will help many people in the forum that have the same doubt.I tell you:

Fast insulin (or fast -acting insulin) is designed to act quickly after administration, but still has a small delay before starting to lower blood glucose.Therefore, it is normally recommended to put it about 15-20 minutes before starting to eat.Thus, when food hydrates begin to rise to blood glucose, insulin is already beginning to take effect and thus better postprandial control (after eating) is achieved.

If you put it just before eating or immediately afterwards, insulin goes "behind" carbohydrates and, therefore, it is easier for glucose to rise long after eating (what we call "glycemic peak").

Now, there are some nuances:

• If you are going to eat very little, or if your glycemia before the food is low, sometimes professionals recommend putting insulin just before or even later, to avoid hypoglycemia.
• It also depends on the rapid insulin type, since the current ultra-abides (such as FIASP or Lyumjev) can act a little faster, and in some cases they are allowed to put just before eating.
• It is always important to individualize and consult with your medical team.

In summary:

As a general rule, the ideal is to manage it about 15-20 minutes before starting to eat.But each person is a world and sometimes you have to adjust based on personal circumstances.

These types of doubts are super important and sharing them a lot of community!

Does anyone else want to share how it does or any personal trick?

A hug and a lot of encouragement!

And it also depends on whether or not there is delay in gastric emptying.Many long evolution diabetics can have what is called Gastroparesia, which is a vagus nerve injury that makes digestion slower.There are degrees, from slight to more serious and is quite frequent in DB of more than 10 years of evolution, especially if the control has been irregular.

According to this, it can be complicated to succeed because you can put the insulin and if it takes four or five hours to empty your stomach, you will have hiccups as soon as you eat for the effect of insulin and after 4 hper pq the effect is over and it is cdo you have finished emptying the stomach and gelling up.

You have to individualize a lot

Also take into account the "glycemic index" (how fast the hydrates are absorbed).More I.G.prick "soon."Less I.G.Click just before or even eating.

Rice: click before.

Chickpeas: just before starting or once started eating.With them I had my first "strong" hypo.It was the time I was trying with the times and click soon, so it began to get off before what I thought.

I usually try to adjust the anticipation time for each type of food according to I.G.To see when I do better.

They have changed my novorapid to Fiasp.So I have to start over with the calculations.

Another detail is what food we are going to click.It is not the same for breakfast as for dinner.

For breakfast I wait between half an hour and an hour between the puncture and start eating.In the rest of the meals I only wait a few minutes.

@Grati It is true that with the legumes (I am a lot of legumes in the lunches) I click just before or even while, depending on the level of blood glucose that you have at the time of starting the food.
