Diabetes treatment: Using insulin to manage blood sugar

It may be easier to understand the importance of insulin therapy if you understand how this naturally occurring hormone usually works in the body and what happens if you have diabetes. If you don't have diabetes, insulin helps: • Regulate blood sugar levels. After you eat, carbohydrates break down into glucose, a sugar that is the body's primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy. • Store excess glucose for energy. After you eat — when insulin levels are high — excess glucose is stored in the liver in the form of glycogen. Between meals — when insulin levels are low — the liver releases glycogen into the bloodstream in the form of glucose. This keeps blood sugar levels within a narrow range. If you have diabetes: Your glucose levels will continue to rise after you eat because there's not enough insulin to move the glucose into your body's cells. People with type 2 diabetes don't use insulin efficiently (insulin resistance) and don't produce enough insulin (insulin deficiency). People with type 1 diabetes make little or no insulin. Untreated, high blood glucose can eventually lead to complications such as blindness, nerve damage and kidney damage. If you have type 1 diabetes, insulin therapy is vital for replacing the insulin your body doesn't produce. Sometimes, people with type 2 diabetes or gestational diabetes need insulin therapy if other tre...

Glucagon: What It Is, Function & Symptoms

What is glucagon? Glucagon is a natural hormone your body makes that works with other hormones and bodily functions to control Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. Your pancreas is a glandular organ in your abdomen that secretes several Glucose is the main sugar found in your blood. You get glucose from carbohydrates in the food you eat. This sugar is an important source of energy and provides nutrients to your body's organs, Your body normally has a complex system to make sure your blood sugar is at optimum levels. If you have too much or too little glucose in your blood, it can cause certain symptoms and complications. Glucagon injections and nasal sprays There’s also a synthetic form of glucagon that can be administered as an What is the function of glucagon? Your body normally carefully regulates your blood glucose (sugar) primarily with the hormones glucagon and insulin. When your blood glucose levels trend lower or fall too low ( • Glucagon triggers your • Glucagon can also prevent your liver from taking in and storing glucose so that more glucose stays in your blood. • Glucagon helps your body make glucose from other sources, such as amino acids. If your blood glucose levels trend higher, your pancreas releases insulin to bring it back into range. What is the difference between glucagon...

How Secreted Insulin Works in Your Body

Insulin is a hormone that helps control your body's blood sugar level and metabolism -- the process that turns the food you eat into energy. Your pancreas makes insulin and releases it into your bloodstream. Insulin helps your body use sugar for the energy it needs, and then store the rest. What Insulin Does After you eat, your intestines break down carbohydrates from food into glucose, a type of sugar. That glucose goes into your bloodstream, which makes your blood sugar level rise. Your pancreas is an organ that sits just behind your stomach. It releases insulin to control the level of glucose in your blood. Your body makes and releases insulin in a feedback loop based on your blood sugar level. At its most basic level, it’s similar to your home's heating and cooling system, which releases cool or warm air as the temperatures rise or fall. High blood sugar stimulates clusters of special cells, called beta cells, in your pancreas to release insulin. The more glucose you have in your blood, the more insulin your pancreas releases. Insulin helps move glucose into cells. Your cells use glucose for energy. Your body stores any extra sugar in your liver, muscles, and fat cells. Once glucose moves into your cells, your blood sugar level goes back to normal. Low blood sugar prompts a different cluster of cells in your pancreas to release another hormone called glucagon. Glucagon makes your liver break down the stored sugar, known as glycogen, and release it into your bloodstream...

Insulin and glucagon: How they regulate blood sugar levels

Insulin and glucagon help maintain blood sugar levels. Glucagon helps prevent blood sugar from dropping, while insulin stops it from rising too high. Insulin and glucagon work together in a balance and play a vital role in regulating a person’s blood sugar levels. Glucagon breaks down glycogen to glucose in the liver. Insulin enables blood glucose to enter cells, where they use it to produce energy. Together, This balance helps provide sufficient energy to the cells while preventing damage that can result from consistently If a person’s body cannot maintain this balance, diabetes and other conditions can result. Prescription insulin and glucagon In this article, we explain the functions and processes of insulin and glucagon, how they work as medications, and their effects on a person’s blood sugar levels. Share on Pinterest stefanamer/Getty Images When a person consumes However, the body does not use all of this glucose at once. Instead, it converts some into storage molecules called glycogen and stores them in the liver and muscles. When the body needs energy, glucagon in the liver converts glycogen back into glucose. From the liver, it enters the bloodstream. There, insulin enables it to enter cells and provide energy for all of the body’s functions In the pancreas, different types of islet cells release insulin and glucagon. Beta cells release insulin while alpha cells release glucagon. How insulin works The body’s cells need glucose for energy, and insulin enables gluc...

Insulin Mechanism of Action: How Does It Work?

Your body produces a wide range of hormones to help control many important functions. Insulin is one of those vital hormones and is produced by your pancreas. It regulates how your body uses glucose, a form of sugar that’s created when your body breaks down the carbohydrates you eat. If your pancreas doesn’t produce insulin at all or doesn’t make enough of it or if the insulin in your body doesn’t work as efficiently as it should, it can cause harmful and even life threatening complications. The most common condition associated with insulin is diabetes. This article will help explain how insulin works, what happens when it stops working, and what the treatment options are. Insulin is a hormone produced by your pancreas that helps control how your body processes, stores, and uses glucose and other important nutrients. Insulin is needed to: • regulate the amount of glucose in your bloodstream • help store glucose in your liver • control how your body metabolizes carbohydrates, proteins, and fats When you eat food, the carbohydrates that you consume get broken down into glucose. Your pancreas then releases insulin so that the glucose in your blood can be transported to the cells in your body. Glucose will either be used as energy by those cells or stored in your liver as glycogen for when it’s needed later. When insulin works this way, it helps keep your blood sugar levels within a healthy range and ensures your body gets the energy it needs to carry out all its essential fun...

Insulin

What is insulin? The main job of insulin is to facilitate the uptake of glucose into the body’s cells. Insulin is a hormone made by the pancreas. The beta cells of the pancreas are stimulated to make insulin when the blood glucose level rises. Insulin tells your muscle, fat, and liver cells to accept glucose from your bloodstream. When these cells take up glucose, they can use it for energy or store it for later use, causing your blood sugar levels to decrease. What is glucose? Glucose is a simple sugar, a type of carbohydrate found in most foods. When broken down, glucose is the main form of energy for the body; our muscles and brain could not function without it. The amount of glucose in the blood must be tightly controlled: glucose is necessary for the body to function properly, but excess glucose in the blood can lead to health complications. As glucose circulates in the blood and comes into contact with cells, insulin allows the glucose to enter those cells to be used for energy. How does insulin work? When we eat, our food is broken down, and glucose is absorbed through our digestive system and released into the bloodstream. This causes our blood glucose level to rise. When the body’s pancreatic beta cells sense this, insulin is released from the pancreas, telling cells in the body to absorb glucose from the blood to be used for energy. Once this happens, your blood glucose levels return to the premeal range. Insulin also helps store glucose in the form of glycogen. ...
