Lesson 1: Diabetes, Insulin, and Insulin Resistance (English)Hyperglycemia and insulin resistance -
Insulin is essential for enabling the body to use glucose effectively and prevent blood sugar levels from rising too high. When insulin does not work effectively, blood sugar levels can rise, and diabetes can develop.
Many people with prediabetes can prevent type 2 diabetes from developing by taking lifestyle measures to counter insulin resistance and the development of diabetes early on. Read this article in Spanish. Insulin helps to stabilize blood sugar in people with diabetes.
Long-acting insulin shots occur once or twice a day, depending on the person and the…. Basal, or background, insulin helps regulate blood sugar levels in people diagnosed with diabetes. It keeps glucose levels steady throughout the day…. Researchers say gastric bypass surgery is more effective than gastric sleeve procedures in helping people go into remission from type 2 diabetes.
A study in mice suggests a potential mechanism that could explain why only some individuals with obesity develop type 2 diabetes. A type of medication used to treat type 2 diabetes could help lower the risk of developing kidney stones, a new study suggests.

Here are the high points: The food you eat is broken down into blood sugar. Blood sugar enters your bloodstream, which signals the pancreas to release insulin.
Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too. But this finely tuned system can quickly get out of whack, as follows: A lot of blood sugar enters the bloodstream.
The pancreas pumps out more insulin to get blood sugar into cells. The pancreas keeps making more insulin to try to make cells respond. Do You Have Insulin Resistance? What Causes Insulin Resistance? How to Reverse Insulin Resistance If you have insulin resistance, you want to become the opposite—more insulin sensitive cells are more effective at absorbing blood sugar so less insulin is needed.

While Natural vitamin alternatives insulin resistance is most frequently seen in the setting of medication side effects or rare genetic conditions, this report of two cases highlights the presence of severe insulin resistance in the setting of severe COVID and explores how this may contribute to the poor prognosis of patients with diabetes who become infected with SARS-CoV Both patients received aggressive insulin infusion and subcutaneous insulin therapy to obtain adequate glucose management. As their COVID clinical course improved, their severe insulin resistance improved as well.

Hyperglycemia-induced insulin resistance also has been described in adipocytes, where it has been linked to activation of novel and conventional protein kinase C isoforms that phosphorylate the insulin receptor and IRS. In addition, we have recently shown that hyperglycemia causes insulin resistance in cultured human umbilical vein endothelial cells HUVEC.
Here, it was associated with an increased propensity to apoptosis and, as in muscle, with an impaired ability of insulin to activate Akt. Interestingly, these effects of hyperglycemia and an increase in diacylglycerol synthesis, which is also caused, were prevented by adding AICAR, an activator of AMP-activated protein kinase AMPKto the incubation medium.
These results suggest that hyperglycemia causes insulin resistance in cells other than those in classic insulin target tissues. Whether AMPK activation can reverse or prevent insulin resistance in all of these cells remains to be determined.
Abstract Sustained hyperglycemia impairs insulin-stimulated glucose utilization and glycogen synthesis in human and rat skeletal muscles, a phenomenon referred to clinically as glucose toxicity.

As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As cells absorb blood sugar, levels in the bloodstream begin to fall. When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar. This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar. Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating. Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops. Advertising revenue supports our not-for-profit mission.
