What Is A Unit Of Insulin

Side Effects Of Abnormal Insulin Levels

Since the insulin is so important to us, it’s vital to maintain normal insulin level. But what if you have abnormal insulin levels?

Side Effects of Low Insulin Levels

The blood sugar level can become elevated if there are reduced amounts of insulin secreted into the blood or the body cells become desensitized to insulin . If this is not carefully managed, patients may develop problems such as kidney disease, nerve damage or loss of vision.

Side Effects of Excessive Insulin

The side effects of excessive blood insulin include:

  • You may experience increased hunger, together with cravings for sugar and carb-rich food. In turn, you will gain weight.
  • Reduced levels of the mineral magnesium in your body cells. Magnesium is needed to relax your blood vessels and promote good blood circulation.
  • Increased retention of sodium, which in turn results in body water retention, leading to hypertension.
  • Lowered levels of beneficial high density lipoprotein , and increased levels of harmful low density lipoprotein and triglycerides. All these factors contribute to the development of heart disease.
  • Increased quantities of inflammatory compounds in the bloodstream. These can directly damage the walls of blood vessels and promote the formation of clots, which could result in respiratory failure or a heart attack.
  • A possible higher risk of cancer. This is because insulin promotes cell proliferation.
  • Fatty liver, polycystic ovary syndrome and increased blood pressure can also happen.

What Are The Different Kinds Of Insulin

There are two different ways in which insulin can be classified.

  • Origin: Is the insulin derived from animal sources, such as beef and/or pork, or human sources in a laboratory? This can be important, as a drug order may specify the origin of the prescribed insulin, because some patients respond more effectively to insulin from one source rather than another.

  • Action: How quickly does the insulin take effect? There are now four basic action speeds of insulin:

  • Rapid Action: The most rapidly-acting insulins are relatively new; of the two brands available, one has been around for 5 years and the other, 10 years . These insulins begin to work in 5-10 minutes, peak in 1-1.5 hours, and end in 3-5 hours. These rapid-acting insulins are taken at the beginning of a meal to counteract the rise in blood sugar due to eating, or they are used to lower blood sugar levels quickly when they are too high. The names lispro and insulin aspart both indicate rapid-action insulins.

  • Fast Action: Fast-acting insulin begins to work in about half an hour, peak in 2.5 to 5 hours, and then end in about 8 hours. Fast action insulins are often taken about a half hour before a meal, to counteract the rise in blood sugar that follows. The names Regular and Semilente both indicate fast-action insulins. To see a visual illustration of the difference in action between rapid and fast-acting insulins, see the charts below which show insulin levels over time in hours after an insulin injection:

  • Units To Milligrams Insulin Conversion

    The conversion factor for human insulin is: One International Unit equals 0.0347 mg of insulin.

    International Units are far easier to understand, especially when it comes to dosing, for insulin. Having a prescription say ‘inject ten units’ is easier to comprehend than ‘inject 0.347 mg’.

    Similarly, when listed as a concentration, such as the commonly used U100 , units correspond tidily with a volume .

    Nevertheless, if you are so inclined to convert between units of insulin and milligrams, you can use this handy conversion tool:

    Insulin: Units To Mg Tool

    Type a value in any of the fields to convert between Insulin measurements:

    *Note: The tool rounds to the ‘hundredths’ place for milligrams

    Total Daily Insulin Requirement:

    = 500 ÷ TDI = 1unit insulin/ 12 g CHO

    This example above assumes that you have a constant response to insulin throughout the day. In reality, individual insulin sensitivity varies. Someone who is resistant in the morning, but sensitive at mid-day, will need to adjust the insulin-to-carbohydrate ratio at different meal times. In such a case, the background insulin dose would still be approximately 20 units; however, the breakfast insulin-to-carbohydrate ratio might be breakfast 1:8 grams, lunch 1:15 grams and dinner 1:12 grams.

    The insulin to carbohydrate ratio may vary during the day.

    Combination With Other Antidiabetic Drugs


    A combination therapy of insulin and other antidiabetic drugs appears to be most beneficial in people who are diabetic, who still have residual insulin secretory capacity. A combination of insulin therapy and is more effective than insulin alone in treating people with type 2 diabetes after secondary failure to oral drugs, leading to better glucose profiles and/or decreased insulin needs.

    How To Count The Units On An Insulin Needle

    Insulin injections are an inevitable part of daily life for people who have Type 1 diabetes, or those using insulin to control blood sugar levels. By combining a healthy diet, exercise, glucose monitoring, and insulin, diabetics can maintain a better overall quality of life. With a bit of concentration and a steady hand, nearly anyone can draw up the correct dosage of insulin, which will help you maintain control over your blood glucose levels.

    Things Youll Need

    • Alcohol swab

    Drawing up the correct dose

    Tips & Warnings

    • Make sure there are no air bubbles trapped in the barrel of the syringe. If there are, gently flick the barrel with your finger, until the bubble floats to the top of the syringe. Once the air bubble is closest to the needle, push the plunger up slightly, just until the bubbles are no longer present. Continue to draw up your dosage of insulin.
    • Consult your doctor when first beginning insulin injections.

    What are the possible side effects of SOLIQUA 100/33?

    Example #1: Carbohydrate Coverage At A Meal

    First, you have to calculate the carbohydrate coverage insulin dose using this formula:

    CHO insulin dose =     Total grams of CHO in the meal ÷ grams of CHO disposed by 1 unit of insulin .

    For Example #1, assume:

    • You are going to eat 60 grams of carbohydrate for lunch
    • Your Insulin: CHO ratio is 1:10

    To get the CHO insulin dose, plug the numbers into the formula:

    CHO insulin dose =

    • The carbohydrate coverage dose is 6 units of rapid acting insulin.
    • The high blood sugar correction dose is 2 units of rapid acting insulin.

    Now, add the two doses together to calculate your total meal dose.

       Carbohydrate coverage dose + high sugar correction dose = 8 units total meal dose!

    The total lunch insulin dose is 8 units of rapid acting insulin.

    What Are Normal Insulin Levels

    Your insulin levels will be typically measured in micro units per milliliter . However, experts often disagree on what should be the “ideal” levels of glucose.

    According to Health Central, the levels should be about 10-20 mcU/ml, while a Dr. Mercola says the normal levels should be under 5 mcU/ml. However, according to Stephen Guyenet, a researcher from University of Washington, the average blood insulin levels in the American population are 8.4 mIU/ml for women and 8.6 mIU/ml for men, but given the prevalence of obesity and metabolic disorders in the US, the ideal level is probably between 2-6 mcU/ml.

    Insulin levels are often assessed after fast for some time. One study, carried out in Arizona, found that women who had a fasting insulin level of 8 mcU/ml were more than twice as likely to develop prediabetes as those with 5 mcU/ml insulin levels. Women with 25 mcU/ml fasting insulin level had over 5 times the risk of prediabetes than women with 5 mcU/ml insulin level.

    Of course, the amount of insulin in the bloodstream will fluctuate in accordance with the levels of glucose. For more information on this, read the table below :


    Normal Insulin Level


    3 hours or more after glucose

    < 25 mIU/L

    *SI Units: Conversional units x 6.945

    The High Blood Sugar Correction Factor:

    Correction Factor = 1800 ÷Total Daily Insulin Dose = 1 unit of insulin will reduce the blood sugar so many mg/dl

    This can be calculated using the Rule of 1800.


    = 1800 ÷ TDI = 1 unit insulin will drop reduce the blood sugar level by 45 mg/dl

    While the calculation is 1 unit will drop the blood sugar 45 mg/dl, to make it easier most people will round up or round down the number so the suggested correction factor may be 1 unit of rapid acting insulin will drop the blood sugar 40-50 mg/dl.

    Please keep in mind, the estimated insulin regimen is an initial best guess and the dose may need to be modified to keep your blood sugar on target.

    Also, there are many variations of insulin therapy. You will need to work out your specific insulin requirements and dose regimen with your medical provider and diabetes team.

    Insulin Sensitivity Factor Or Correction Dose

    How to Convert U

    To create an Insulin Sensitivity Factor for RAPID insulin:

    • 100/TDD = number of mmol/L 1 unit rapid will lower glucose level.E.g. 100/50 units TDD = 2 1 unit will drop glucose by about 2 mmol/L

    To create an Insulin Sensitivity Factor for REGULAR insulin:

    • 83/TDD = number of mmol/L 1 unit regular insulin will lower glucose level. E.g. 83/30 units TDD = about 3. 1 unit will lower glucose by about 3 mmol/L

    To use an ISF:

    • / ISF= units to give to correct high glucose reading
    • e.g. If current BG 13 mmol/L , ISF is 2 and target is 7 mmol then:13 mmol/L – 7 mmol/L  = 6 / ISF 2 = 3 units for correction 


    • To create and adjust a correction scale, see the

    Insulin Analogs Vs Human Insulin

    There is also another, very important reason, why insulin products aren’t listed in milligrams and that has to do with the existence of Insulin analogs.

    Insulin analogs and human insulin technically use the same conversion and are considered ‘equipotent’.

    Nevertheless, there are significant differences in the pharmacokinetic profiles of each .

    Human Insulin

    • Regular insulin .
    • NPH insulin .

    Regular human insulin products are considered ‘fast-acting’, with an onset of action around 30 minutes. High concentration regular human insulin , have a slightly faster onset of action and duration of action.

    NPH insulin is also known as isophane insulin and is intermediate-acting. It is regular human insulin with added zinc and protamine, which causes a delay in absorption and prolongs the duration of action.

    Insulin Analogs

    Insulin analogs are altered forms of insulin and are manufactured via genetic engineering. Analogs are created in such a way to alter their pharmacokinetic characteristics from human insulin.

    For example, there are several ‘rapid’ acting insulin analogs, and have a faster onset of action than human insulin products. These include:

    • Insulin  

    Conversions Between Human And Analog Insulin

    Although all insulin products are considered ‘equipotent’ in regard to the fact that 1 unit of each equals 0.0347 mg, as described above, they have significant differences in their onset of action, time to peak effect, and duration of action.

    First Some Basic Things To Know About Insulin:

    • Approximately 40-50% of the total daily insulin dose is to replace insulin overnight, when you are fasting and between meals. This is called background or basal insulin replacement. The basal or background insulin dose usually is constant from day to day.
    • The other 50-60% of the total daily insulin dose is for carbohydrate coverage and high blood sugar correction. This is called the bolus insulin replacement.

    Bolus Carbohydrate coverage

    The bolus dose for food coverage is prescribed as an insulin to carbohydrate ratio.The insulin to carbohydrate ratio represents how many grams of carbohydrate are covered or disposed of by 1 unit of insulin.

    Generally, one unit of rapid-acting insulin will dispose of 12-15 grams of carbohydrate. This range can vary from 6-30 grams or more of carbohydrate depending on an individuals sensitivity to insulin. Insulin sensitivity can vary according to the time of day, from person to person, and is affected by physical activity and stress.

    Bolus High blood sugar correction

    The bolus dose for high blood sugar correction is defined as how much one unit of rapid-acting insulin will drop the blood sugar.

    Generally, to correct a high blood sugar, one unit of insulin is needed to drop the blood glucose by 50 mg/dl. This drop in blood sugar can range from 30-100 mg/dl or more, depending on individual insulin sensitivities, and other circumstances.

    Evolution And Species Distribution

    Insulin may have originated more than a billion years ago. The molecular origins of insulin go at least as far back as the simplest unicellular . Apart from animals, insulin-like proteins are also known to exist in the Fungi and Protista kingdoms.

    Insulin is produced by beta cells of the pancreatic islets in most vertebrates and by the Brockmann body in some teleost fish.Cone snailsConus geographus and Conus tulipa, venomous sea snails that hunt small fish, use modified forms of insulin in their venom cocktails. The insulin toxin, closer in structure to fishes’ than to snails’ native insulin, slows down the prey fishes by lowering their blood glucose levels.

    Why We Can Use Iu As Insulin Unit

    IU stands for International Units and is used for the measurement of drugs and vitamins. Since each substance would have a different conversion ratio, we cannot put up a conversion for IU to milligrams that covers everything, or even most things. In pharmacology, the international unit is a unit of measurement for the amount of a substance; the mass or volume that constitutes one international unit varies based on which substance is being measured, and the variance is based on the biological activity or effect, for the purpose of easier comparison across substances. International units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and similar biologically active substances.Continue reading >>

    Regulator Of Endocannabinoid Metabolism

    Insulin is a major regulator of and insulin treatment has been shown to reduce ECs, the and , which correspond with insulin-sensitive expression changes in enzymes of EC metabolism. In insulin-resistant , patterns of insulin-induced enzyme expression is disturbed in a manner consistent with elevated EC and reduced EC degradation. Findings suggest that adipocytes fail to regulate EC metabolism and decrease intracellular EC levels in response to insulin stimulation, whereby insulin-resistant individuals exhibit increased concentrations of ECs. This dysregulation contributes to excessive visceral fat accumulation and reduced release from abdominal adipose tissue, and further to the onset of several cardiometabolic risk factors that are associated with obesity and type 2 diabetes.

    , also known as “low blood sugar”, is when blood sugar decreases to below normal levels. This may result in a variety of including clumsiness, trouble talking, confusion, loss of consciousness, or death. A feeling of hunger, sweating, shakiness and weakness may also be present. Symptoms typically come on quickly.

    How Much Does 1 Unit Of Insulin Bring Your Sugar Down

    Question Originally asked by Community Member karen How Much Does 1 Unit Of Insulin Bring Your Sugar Down Using a chart to give my mother her insulin, sometimes it just seams its not bringing her sugar down to a lower level. Answer The âcorrection factorâ is the term used for the amount of insulin a person needs in order to bring their blood sugar down to 120. It is different for everyone! Your motherâs endocrinologist should have a note of what this dose has been in the past, but you can also figure this out purely by conducting SAFE trial and error. If her blood sugar is at 200, try giving her one unit of insulin and test her blood sugar a half hour later, and then an hour later. If itâs still high, give another. For example, in MY body, if my blood sugar is at 200, I take two units of insulin to bring it down to 100 to 120. If I was going to be doing any exercise also at this time, i would only take one unit as my âcorrection factorâ because the exercise would help bring the blood sugar down, too.

    You’ll Need To Calculate Some Of Your Insulin Doses

    You’ll also need to know some basic things about insulin. For example, 40-50% of the total daily insulin dose is to replace insulin overnight.

    Your provider will prescribe an insulin dose regimen for you; however, you still need to calculate some of your insulin doses. Your insulin dose regimen provides formulas that allow you to calculate how much bolus insulin to take at meals and snacks, or to correct high blood sugars.

    How To Convert U

    Insulin is an injectable medication used to treat diabetes mellitus in dogs, cats, and other animal species. It is available in a variety of types and strengths. There are also different sizes of insulin syringes that are made to go with the varying types of insulin.

    KEY POINT: There are different types of insulin syringes. It is critical to match the correct syringe with the accompanying type of insulin to administer an accurate dose.

    The best way to ensure that you give the correct amount of insulin to your cat or dog is to understand the strength and type of insulin and use the syringe that is made to go with the applicable insulin.

    They may be instances where you are unable to match your syringe and insulin type, due to lack of availability or an emergency. This article is designed to help pet owners accurately convert insulin units to ml.

    How To Lower Insulin Levels

    Low insulin level can be mended by taking insulin injection. But cases of excessive insulin level are common and hard to deal with, so we will further talk about lowering and maintaining normal insulin levels.

    1. Change Your Diet

    To lower your levels of insulin, try eating more dark green vegetables and whole-grain foods rich in fiber. Avoid alcohol and anything containing refined sugar or trans-fats. Patients who followed these guidelines had decreased fasting insulin levels and female patients had lowered insulin resistance. For men, reducing the waist circumference may have a role in decreasing blood insulin levels and insulin resistance.

    2. Lower Your Glycemic Index

    Exercise can enhance insulin-mediated uptake of glucose into muscle tissue, and therefore reduce the body’s need for insulin. Physical activity is particularly effective when combined with a low glycemic index diet, which can also reduce the body’s insulin requirements. The glycemic index measures the effect of a particular food on blood glucose levels. One study showed that obese older adults with prediabetes lost weight and decreased their blood insulin after both exercising and eating low-GI food.

    3. Take Some Medication

    Definition Of 1 Unit Of Rapid Insulin

    How is insulin measured?

    • Insulin is measured in units. Insulin is available in “U100” or “U500”. U100 is the most common type of insulin. It has 100 units of insulin in 1 mL of solution. You must inject U100 insulin with U100 syringes. U500 insulin has 500 units of insulin in 1 mL. This type of insulin is rarely used, and mainly for people who are insulin-resistant. Insulin resistance is a condition where a person’s body cannot respond to and use insulin as it should. A special type of syringe is needed for U500 insulin.

    What Are Normal Levels Of Insulin

    Many people carefully monitor their glucose levels for signs of diabetes, but how many do the same with insulin levels? Your body requires constant circulation of insulin in the blood all the time, even when you’re not eating. The level of insulin circulating in your bloodstream is a good indication of your overall health and may be able to predict your risk of sudden death, so it’s really useful to know your insulin levels. But what levels of insulin are normal, and how do you know when things have gone awry?
