Symptoms of Type 1 Diabetes
Type 2 diabetes is an impairment in the way the body regulates and uses sugar glucose as a fuel. This long-term chronic condition results in too much sugar circulating in the bloodstream. Eventually, high blood sugar levels can lead to disorders of the circulatory, nervous and immune systems.
In type 2 diabetes, there are primarily two interrelated problems at work. Your pancreas does not produce enough insulin — a hormone that regulates the movement of sugar into your cells — and cells respond poorly to insulin and take in less sugar. Type 2 diabetes used to be known as adult-onset diabetes, but both type 1 and type 2 diabetes can begin during childhood and adulthood.
Type 2 is more common in older adults, but the increase in the number of children with obesity has led to more cases of type 2 diabetes in younger people. There's no cure for type 2 diabetes, but losing weight, eating well and exercising can help you manage the disease. If diet and exercise aren't enough to manage your blood sugar, you may also need diabetes medications or insulin therapy. Signs and symptoms of type 2 diabetes often develop slowly. In fact, you can be living with type 2 diabetes for years and not know it.
When signs and symptoms are present, they may include:. Exactly why this happens is unknown, but being overweight and inactive are key contributing factors.
Insulin is a hormone that comes from the gland situated behind and below the stomach pancreas. Insulin regulates how the body uses sugar in the following ways:. Glucose — a sugar — is a main source of energy for the cells that make up muscles and other tissues. The use and regulation of glucose includes the following:. In type 2 diabetes, this process doesn't work well. Instead of moving into your cells, sugar builds up in your bloodstream.
As blood sugar levels increase, the insulin-producing beta cells in the pancreas release more insulin. Eventually these cells become impaired and can't make enough insulin to meet the body's demands. In the less common type 1 diabetes, the immune system mistakenly destroys the beta cells, leaving the body with little to no insulin. Type 2 diabetes affects many major organs, including your heart, blood vessels, nerves, eyes and kidneys.
Also, factors that increase the risk of diabetes are risk factors for other serious chronic diseases. Managing diabetes and controlling your blood sugar can lower your risk for these complications or coexisting conditions comorbidities. Healthy lifestyle choices can help prevent type 2 diabetes, and that's true even if you have biological relatives living with diabetes. If you've received a diagnosis of prediabetes, lifestyle changes may slow or stop the progression to diabetes.
For people with prediabetes, metformin Fortamet, Glumetza, others , an oral diabetes medication, may be prescribed to reduce the risk of type 2 diabetes. This is usually prescribed for older adults who are obese and unable to lower blood sugar levels with lifestyle changes. Mayo Clinic does not endorse companies or products.
