I was diagnosed as Type 2 non-insulin dependent over 25 years ago. Through those years I have had times that I was very on track with my management and times I was off track. Recently, my team of physicians has decided that with all my diagnoses taken into consideration and the current state of my overall health, I needed to cease working and apply for disability. This is currently in process. This brings me to my current question. I have, since no longer working, had an opportunity to focus on my health management. for several years I have taken Humalog and Lantus. My problem is that I am experiencing a lot of super lows and super highs. I have been instructed to start taking my Humalog on a sliding scale, rather than a fixed dose, according to my blood sugar reading and my carbohydrate count for my meal. I need to have the "Rule of 1500" explained to me so that I can start calculating my Humalog dosage. Any help would be greatly appreciated. Thank you.

Without the proper medical training, it would be irresponsible for me to answer this. I did google "Insulin Sliding Scale" and came up with many hits. Your doctor is in the best position to answer these questions. Each individual's insulin sensitivity is different and can vary tremendously. Your Insulin sensitivity value indicates how much 1 unit of bolus insulin will lower your BG. For example, my insulin sensitivity is 100 so I can expect 1 unit of NovoLog to reduce my BG by 100 mg/dl's. Most diabetics have a lower sensitivity level than I do. Insulin sensitivity will affect any correction doses that you might need. Evidently, the "Rule of 1500 Insulin" is a calculation method to determine insulin sensitivity. Per my Google search "The 1500 rule works as follows: Divide 1500 by the total daily dose of Regular insulin, in units. For example, if a person's total daily dose is 30 units of Regular insulin, his insulin sensitivity factor would be 50 (1500 รท 30). So one unit of Regular insulin would be estimated to lower his blood glucose by 50 mg/dl." But by the date on this ,Jun 15, 2006, this is old and refers to "Regular" insulin, not Humalog. There may be other, newer, ways of determining your insulin sensitivity. Gary Scheiner's book "Think Like a Pancreas" has a chart which uses your total combined basal and bolus insulin to calculate your insulin sensitivity. His book is my go-to manual for understanding how to treat my diabetes with insulin. How many total insulin units are you taking per day? I'd be happy to look at Gary Scheiner's chart and let you know what it says about your insulin sensitivity factor.
