Insulin. What Does It Do?

Glucose comes from the digestion of almost all foods, especially starchy ones. We need insulin to make energy from the glucose in these foods. Insulin is a special chemical (hormone) made by the pancreas gland, and allows the glucose from the blood stream to get in to our body’s cells to give us energy. Without insulin the glucose remains in the bloodstream and cannot give us the energy we need. In someone who does not have diabetes the amount of insulin produced depends on the amount of glucose/starchy foods eaten and the energy used and needed. Blood glucose level stays between 3.5 mmol/L and 7 mmol/L What happens when there is not enough insulin? When the pancreas fails to make enough insulin the glucose remains in the blood stream and the blood glucose level rises. This may come on gradually but eventually the glucose levels in the blood rise so high that they spill out of the blood stream through the kidneys and into the urine. The high blood sugar also pulls water out of the bloodstream, causing you to pass additional urine. This in turn makes you very thirsty. If the glucose in the blood cannot be used for energy the body has to find other alternative fuels. The body begin Continue reading >>

    Why does my insulin make my blood sugar rise/do nothing sometimes?

    My blood sugar was 224, so I took my insulin like directed, I waited 15 minutes, 235. I tried to calm myself down but my anxiety started to rise (anytime I go above 200 I feel like the worst person, that my doctor will think I'm the worst, all kinds of terrible things). I waited another 15 minutes and now it's 255. I took my insulin, novolog so fast acting, I haven't eaten in over an hour, and I took correct amount of insulin with my meal. Why is this happening? Is this normal? Also, sometimes when I go high, I start shaking and feeling like I'm low, though obviously I'm not. Any ideas?

    So after an hour and a half, and 8 units of insulin, it's dropping, slowly, but it's dropping. I am on my period, could this just be hormonal stuff?
