When you have looked at the results of your urine and blood sugar tests and come to the conclusion that the insulin dose has got to be changed, you must ask yourself the following questions:
1. Should the dose be increased or decreased?
Next you must ask:
2. By how many units must the dose be increased or decreased?
If you are having insulin injections in the evenings and in the mornings you must also ask:
3. Must the increase or decrease be made in the morning or in the evening?
First of all we will try to answer Question No. 2:
The general 'rule' which normally applies is that you can increase or decrease the dose of insulin by about 10% of the dose which you usually inject;
that means
if you inject 10 units, by 1 unit,
if you inject 20 units, by 2 units,
if you inject 30 units, by 3 units,
and so on.
"And if the dose is something in between?" You're quite right, let's try to formulate
the rule more precisely:
If you give 10 units or less in each injection, change the dose by 1 unit.
If you give between 11 and 20 units in each injection, change it by 2 units.
If you give between 21 and 30 units in each injection, change it by 3 units.
