Can Lantus insulin cause serious lows? It can. Lantus (insulin glargine) is a long-acting basal insulin that is supposed to be released slowly and evenly throughout approximately 24 hours. The actual time it last varies in different patients. Bolus, or prandial, insulins are fast-acting insulins, and if you inject too much of them, or don't eat as much as you thought you were going to eat when you calculated the bolus dose, the result can be serious low blood sugar ( hypoglycemia ), because the insulin works quickly. People don't expect Lantus to cause hypoglycemia because it's supposed to be released slowly, a little bit at a time. However, although this is rare, Lantus can cause serious hypoglycemia if it's injected into a blood vessel. This happened to me once and several times to a good e-mail friend whose observational skills I trust. Neither of us uses bolus insulin. At least several people I don't know have reported similar episo...
An insulin testis a blood test that measures the amount of insulin, a hormone that regulates blood sugar.
How the test is performed
Blood is drawn from a vein on the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to fill with blood.
A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. After the blood is drawn, the band is removed to restore circulation. Then, the needle is removed, and the puncture site is covered to stop any bleeding.
For an infant or young child:
The area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site i...
Normally, there are no antibodies against insulin in your blood.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results mean
If you have IgG and IgM antibodies against insulin, your body reacts as if the insulin is foreign. This may make insulin less effective, or not effective at all.
The antibodies can also change the amount of time it takes insulin to work, putting you at risk for low blood sugar. This means that the insulin cannot move glucose from the bloodstream into the cells. As a result, increased levels of insulin are needed to have the same effect, which is called insulin resistance.
If the test shows high levels of IgE antibody against insulin, your body has developed an allergic response to the medication. This could put you at risk for skin reactions, or more severe reactions. Other medications, such as antihistamines or low-dose i...
