Insulin is a hormone produced by the pancreas, which helps to regulate the blood glucose level. This hormone is essential to transport and store glucose in the cells and helps to use glucose as an energy source for the organism.

Insulin acts as a key to let the glucose access the cells. If glucose cannot enter into the cells, it accumulates in the blood.

The pancreas produces insulin in two ways:

  • Slow and continuous insulin that helps blood glucose levels to remain always stable between 70-100 mg/dl, known as basal insulin secretion.
  • Another one, bolus insulin, secreted in a larger quantity, generally when the sanguineous glucose is increasing after meals, known as pulsatile insulin secretion.

Types of insulin

Depending on the type of insulin you use, the starting time effect varies, i.e., the moment in which insulin starts lowering the blood sugar level.

Moreover, it is necessary to know the peak, when insulin reaches its maximum effect, in which the the blood glucose level will be reduced.

There should be an awareness of the duration of the insulin effects that means, the period when the blood glucose level will keep lowering.

Insulin is classified into several groups:

Fast-acting insulin

It is rapidly absorbed from adipose (subcutaneous) tissue in the bloodstream. It is used to control blood glucose during the ingestion of food or drinks, and corrects the high blood sugar levels.

Start 10 – 15 minutes
Peak 30 – 90 minutes
Duration 3 – 5 hours

 

Examples: Apidra, Humalog, Novorapid, etc.

¿ME HE PUESTO YA LA INSULINA?

Insulclock es capaz de decirte si ya te has pinchado, te recuerda que debes pincharte si aún no lo has hecho, rellena el cuaderno del diabético por ti y hasta es capaz de saber si tu pluma ha estado expuesta a temperaturas que hagan que la insulina pueda haber perdido sus propiedades.



Short-acting or regular insulin

As its name suggests, they are short-acting insulins, usually takes longer to produce an effect.

Start 30 – 60 minutes
Peak 2 – 3 hours
Duration 5 – 7 hours

   

Example: Actrapid.

Intermediate acting insulin

This type of insulin acts like basal insulin, it is absorbed slower, extending the duration of its effect. It is administered once or twice a day and is specially used to control the blood glucose level during the night, fasting or between meals. It is normally combined with fast-acting insulins.

Start 1 – 2 hours
Peak 4 – 7 hours
Duration 10 – 13 hours

Example: Humulin N.

Long-acting insulin

Like with intermediate-acting insulins, it is used like basal insulins and is slowly absorbed, having a minimum peak effect. Its effect is more stable during most part of the day.

Start 1 – 2 hours
Peak 6 – 7 hours
Duration 24 – 36 hours

Examples: Tresiba, Toujeo, Levemir, Lantus.

Premixed Insulins

These are combinations of fast-acting insulins with intermediate-acting insulins, in different proportions. It is only necessary an injection of premixed insulin to control both basal and prandial glycemia.

It is impossible to take insulin pills because it would decompose during the digestion. It has to be injected into the fat located under the skin so that it can be incorporated into the blood.

We leave you the following link about how to inject insulin. Moreover, remember that our device Insulclock works with all the mentioned insulin pens.
