What is Diabetes?
Diabetes is a chronic (long-lasting) health condition that affects how your body turns food into energy.
Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Sometimes your body doesn’t make enough—or any—insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells.

What are the different types of diabetes?
The most common types of diabetes are type 1, type 2, and gestational diabetes.
Diabetes Symptoms
- Urinate (pee) a lot, often at night
- Are very thirsty
- Lose weight without trying
- Are very hungry
- Have blurry vision
- Have numb or tingling hands or feet
- Feel very tired
- Have very dry skin
- Have sores that heal slowly

Symptoms of Type 1 Diabetes
People who have type 1 diabetes may also have nausea, vomiting, or stomach pains. Type 1 diabetes symptoms can develop in just a few weeks or months and can be severe. Type 1 diabetes usually starts when you’re a child, teen, or young adult but can happen at any age.
Symptoms of Type 2 Diabetes
Type 2 diabetes symptoms often take several years to develop. Some people don’t notice any symptoms at all. Type 2 diabetes usually starts when you’re an adult, though more and more children and teens are developing it. Because symptoms are hard to spot, it’s important to know the risk factors for type 2 diabetes. Make sure to visit your doctor if you have any of them.
Symptoms of Gestational Diabetes
Gestational diabetes (diabetes during pregnancy) usually doesn’t have any symptoms. If you’re pregnant, your doctor should test you for gestational diabetes between 24 and 28 weeks of pregnancy. If needed, you can make changes to protect your health and your baby’s health.

How common is diabetes?
As of 2015, 30.3 million people in the United States, or 9.4 percent of the population, had diabetes. More than 1 in 4 of them didn’t know they had the disease. Diabetes affects 1 in 4 people over the age of 65. About 90-95 percent of cases in adults are type 2 diabetes.

The role of glucose
Glucose — a sugar — is a source of energy for the cells that make up muscles and other tissues.
- Glucose comes from two major sources: food and your liver.
- Sugar is absorbed into the bloodstream, where it enters cells with the help of insulin.
- Your liver stores and makes glucose.
- When your glucose levels are low, such as when you haven't eaten in a while, the liver breaks down stored glycogen into glucose to keep your glucose level within a normal range.
How insulin works
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).
- The pancreas secretes insulin into the bloodstream.
- The insulin circulates, enabling sugar to enter your cells.
- Insulin lowers the amount of sugar in your bloodstream.
- As your blood sugar level drops, so does the secretion of insulin from your pancreas.
