How Do I Increase Insulin Sensitivity?

What is insulin sensitivity? Definitions Insulin sensitivity is a general phenomena in the body, and can be measured a few ways through studies. The pancreas (an organ that regulates blood sugar) secretes insulin in response to high blood sugar, and cells (like muscle or fat cells) can absorb blood sugar when stimulated by insulin. Insulin sensitivity is the relationship between how much insulin needs to be produced in order to deposit a certain amount of glucose. You are insulin sensitive if a small amount of insulin needs to be secreted to deposit a certain amount of glucose, and insulin resistant if a lot of insulin needs to be secreted to deposit the same amount of glucose. Insulin sensitivity is seen as good as the opposite, insulin resistance, is a major risk factor for the development of Type II diabetes. Types of Insulin Sensitivity There are three main types of insulin sensitivity; peripheral insulin sensitivity, hepatic insulin sensitivity, and pancreatic insulin sensitivity. Peripheral insulin sensitivity is how readily body cells in your periphery tissue, such as muscle and fat, can absorb glucose; either on their own (muscle can absorb glucose when contracted) or when Continue reading >>

    The V-Go is aimed at people with Type 2 diabetes. It has set basal delivery rates - the same amount is delivered each hour and it can't be changed. You also don't really get to choose how much because the device comes in 3 doses - 20, 30 or 40 units per day (that applies to the basal only). If you divide each of those amounts by 24, you get the amount per hour it delivers as basal. For the majority of people with Type 1 this wouldn't work. You can also use up to 36 units per day for boluses and those are delivered in 2 unit increments. Again, not very practical for people who are sensitive to insulin. I also don't see this device working for many people with Type 2 who are insulin resistant. There are people who take 50+ units of basal insulin twice a day via pen or syringe and also require large boluses to cover meals.
    A real pump allows you to have multiple basal rates throughout the day. You can also increase or decrease those rates temporarily to account for thinks like illness or exercise. You can bolus in much finer increments. 1/40th of a unit vs. 2 full units on the V-Go! You can also set up a bolus to deliver slowly over time to account for meals that take longer to digest.

    The prevalence of insulin-resistant conditions—such as obesity, the metabolic syndrome, and type 2 diabetes—is on the increase, affecting all age groups and both sexes.1 A sedentary lifestyle lies at the core of these disorders; therefore, increased physical activity is considered an integral part of lifestyle modification for the prevention and treatment of insulin resistance.2,3 There is a wealth of epidemiological evidence indicating that ...

  • How Does Exercise Affect Insulin Sensitivity?

    Insulin is an essential hormone that controls your blood sugar levels. It's made in your pancreas and helps move sugar from your blood into your cells for storage. When cells are insulin resistant, they can't use insulin effectively, leaving your blood sugar high. When your pancreas senses high blood sugar, it makes more insulin to overcome the resistance and reduce your blood sugar. Over time, this can deplete the pancreas of insulin-producing c ...

  • Exercise Insulin Sensitivity

    Insulin resistance (IR) is a pathological condition in which cells fail to respond normally to the hormone insulin. The body produces insulin when glucose starts to be released into the bloodstream from the digestion of carbohydrates in the diet. Normally this insulin response triggers glucose being taken into body cells, to be used for energy, and inhibits the body from using fat for energy. The concentration of glucose in the blood decreases as ...

  • Inflammation And Insulin Resistance Review

    Yes. In fact, calorie restriction induces a reduction in the insulin signalling pathways (both through IGF-I and insulin), and this reduction in insulin signalling pathways is thought to be one of the primary mechanisms through which calorie restriction acts to increase lifespan. High blood insulin levels are usually the result of high blood glucose levels. So high levels of insulin signalling are a signal of high "nutritional state", and shift a ...

  • Estrogen And Insulin Sensitivity

    Estrogen has many beneficial effects in the body, including helping optimize the action of insulin, the hormone that prevents high blood sugar levels. Consequently, low estrogen levels may lead to insulin resistance, or impaired insulin action. Insulin resistance is linked to metabolic syndrome, a group of traits and medical conditions that increase the risk of health problems such as diabetes, heart attack and stroke. Low estrogen levels and ins ...
