How Your Body Uses Glucose and Insulin: American Diabetes Association®
Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. As blood sugar levels. Insulin's main task is to help turn carbohydrates from food into the energy that keeps the body running. After they are eaten, carbs are broken down into the sugar. Insulin affects carbohydrate, protein, and fat metabolism. Your body breaks these nutrients down into sugar molecules, amino acid molecules.
What is Insulin? - Important hormone allows your body to use sugar (glucose)
People with type 2 diabetes do not respond well or are resistant to insulin. They may need insulin shots to help them better process sugar and to prevent long-term complications from this disease. Persons with type 2 diabetes may first be treated with oral medications, along with diet and exercise. Since type 2 diabetes is a progressive condition, the longer someone has it, the more likely they will require insulin to maintain blood sugar levels.
Various types of insulin are used to treat diabetes and include: It starts working approximately 15 minutes after injection and peaks at approximately 1 hour but continues to work for two to four hours. This is usually taken before a meal and in addition to a long-acting insulin. It starts working approximately 30 minutes after injection and peaks at approximately 2 to 3 hours but will continue to work for three to six hours.
It is usually given before a meal and in addition to a long-acting insulin.
Type 2 Diabetes: What Is It?
It starts working approximately 2 to 4 hours after injection and peaks approximately 4 to 12 hours later and continues to work for hours. It is usually taken twice a day and in addition to a rapid- or short-acting insulin. It starts working after several hours after injection and works for approximately 24 hours. If necessary, it is often used in combination with rapid- or short-acting insulin. Insulin helps the glucose get into the body's cells. Your body gets the energy it needs.
The pancreas is a long, flat gland in your belly that helps your body digest food. It also makes insulin. Insulin is like a key that opens the doors to the cells of the body. It lets the glucose in. Then the glucose can move out of the blood and into the cells. But if someone has diabetes, either the body can't make insulin or the insulin doesn't work in the body like it should.
The glucose can't get into the cells normally, so the blood sugar level gets too high. Lots of sugar in the blood makes people sick if they don't get treatment.
What Is Type 2 Diabetes? There are two major types of diabetes: Each type causes high blood sugar levels in a different way.
In type 1 diabetesthe pancreas can't make insulin. The body can still get glucose from food, but the glucose can't get into the cells, where it's needed, and glucose stays in the blood.
This makes the blood sugar level very high.
Type 2 Diabetes: What Is It?
With type 2 diabetes, the body still makes insulin. But a person with type 2 diabetes doesn't respond normally to the insulin the body makes. So glucose is less able to enter the cells and do its job of supplying energy. When glucose can't enter the cells in this way, doctors call it insulin resistance.
Although there's plenty of insulin in the person's body, because it doesn't work properly, the pancreas still detects high blood sugar levels. This makes the pancreas produce even more insulin. The pancreas may eventually wear out from working overtime to produce extra insulin. When this happens, it may no longer be able to produce enough insulin to keep blood sugar levels where they should be.
In general, when someone's blood sugar levels are repeatedly high, it's a sign that he or she has diabetes. Who Gets Type 2 Diabetes? What makes people more likely to develop type 2 diabetes? No one knows for sure. But experts have a few ideas about what puts a person at greater risk: Most people who have type 2 diabetes are overweight.
People with family members who have diabetes get diabetes more often. People who are older than 10 are more likely to develop type 2 diabetes than younger kids.
How Insulin and Glucagon Work
People who have type 2 diabetes may not know it because the symptoms aren't always obvious and they can take a long time to develop. Some people don't have any symptoms at all.
But when a person gets type 2 diabetes, he or she may: This can cause a dark ring around the neck that doesn't wash off, as well as thick, dark, velvety skin under the arms, in between fingers and toes, between the legs, or on elbows and knees.
This skin darkening can lighten over time with improvement in insulin resistance.
