What is a Diabetes?
Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar. Hyperglycemia, or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels.Type 1 diabetes (previously known as insulin-dependent, juvenile or childhood-onset) is characterized by deficient insulin production and requires daily administration of insulin. The cause of type 1 diabetes is not known and it is not preventable with current knowledge.
Symptoms include excessive excretion of urine (polyuria), thirst (polydipsia), constant hunger, weight loss, vision changes and fatigue. These symptoms may occur suddenly. Type 2 diabetes (formerly called non-insulin-dependent or adult-onset) results from the body’s ineffective use of insulin. Type 2 diabetes comprises the majority of people with diabetes around the world, and is largely the result of excess body weight and physical inactivity.
Symptoms may be similar to those of Type 1 diabetes, but are often less marked. As a result, the disease may be diagnosed several years after onset, once complications have already arisen.
Until recently, this type of diabetes was seen only in adults but it is now also occurring increasingly frequently in children. Gestational diabetes is hyperglycemia with blood glucose values above normal but below those diagnostic of diabetes, occurring during pregnancy. Women with gestational diabetes are at an increased risk of complications during pregnancy and at delivery. They and their children are also at increased risk of type 2 diabetes in the future.
Gestational diabetes is diagnosed through prenatal screening, rather than through reported symptoms.
Diagnosis and Treatment
Early diagnosis can be accomplished through relatively inexpensive testing of blood sugar. Treatment of diabetes involves diet and physical activity along with lowering blood glucose and the levels of other known risk factors that damage blood vessels. Tobacco use cessation is also important to avoid complications.Interventions that are both cost-saving and feasible in developing countries include:
- Blood glucose control, particularly in type 1 diabetes. People with type 1 diabetes require insulin, people with type 2 diabetes can be treated with oral medication, but may also require insulin.
- Blood pressure control.
- Foot care.
Other cost saving interventions includes:
- Screening and treatment for retinopathy (which causes blindness).
- Blood lipid control (to regulate cholesterol levels).
- Screening for early signs of diabetes-related kidney disease and treatment.
Simple lifestyle measures have been shown to be effective in preventing or delaying the onset of type 2 diabetes. To help prevent type 2 diabetes and its complications, people should:
- Achieve and maintain healthy body weight.
- Be physically active; at least 30 minutes of regular, moderate-intensity activity on most days. More activity is required for weight control.
- Eat a healthy diet, avoiding sugar and saturated fats intake.
- Avoid tobacco use; smoking increases the risk of diabetes and cardiovascular diseases.
- The number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014.
- Over time, diabetes can damage the heart, blood vessels, eyes, kidneys, and nerves.
- Diabetes is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation.
- Almost half of all deaths attributable to high blood glucose occur before the age of 70 years. WHO projects that diabetes will be the 7th leading cause of death in 2030.
- Healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use are ways to prevent or delay the onset of type 2 diabetes.
- Diabetes can be treated and its consequences avoided or delayed with diet, physical activity, medication and regular screening and treatment for complications.
