    Am I using my insulin correctly for type 2 diabetes?

    Type two diebeties:Lately I have been taking my insulin AFTER I get the blood results. I wait 30 minutes after I have a meal to see my sugar results and take my insulin amount after I get a more exact reading of what my level is at the time. It seems to work quite well because after another 30 minutes I check again and it seems to have a greater reaction and REDUCTION, the sugar levels seem much less. Is this a reliable method and can I continue doing it this way ?

    HI there,
    There are a couple of different types of insulin that can be prescribed for someone with type 2 diabetes:
    - rapid acting and longer acting taken separately
    - mixed insulin where the rapid and longer acting are mixed together.
    Regardless of the type the rapid acting insulin will start working in 10-15 minutes.

    After eating carbohydrate foods we get a nearly immediate rise in blood glucose levels so by waiting for 30 minutes you will have let your blood glucose levels rise quite significantly already. The time for glucose levels to peak after eating is usually 1 hour before it then starts to go down - hopefully to pre-meal levels.

    Usually the decision of how much insulin to inject is based on the pre-meal blood glucose reading rather than 30 minutes after the meal, in this way the insulin can start acting on the rise in blood glucose levels soon after you eat and prevent the blood glucose levels after the meal from getting too high.

    It sounds like you are really thinking about how best to manage your type 2 diabetes which is great. Having a chat with a diabetes educator about your management is a really good place to start - a team approach works best here - with you in charge.
    Good Luck.

    Thank you for your insite,I am trying my best but loosing the battle of the bulge and of course there by the battle of this incidious desease. Aparently “so I have heard” the insulin also makes it even harder to loose the weight, but that's life. Again thank you.

    It is a tricky disease but it really is best managed by a team, and yes, insulin does make weight loss more difficult, but not impossible.  If you haven't already I would recommend talking to your GP about a referral to a diabetes educator and a dietitian.
    All the best.
