Diabetes Overview: Definition and Causes
Diabetes is a chronic metabolic disorder where the body cannot properly regulate blood sugar (glucose) levels. This happens either because the body does not produce enough insulin, or the insulin it does produce does not work effectively. Insulin is a hormone made in the pancreas that is essential for moving glucose from the blood into the cells for energy. When this process fails, blood sugar levels become abnormally high, leading to diabetes 2310.
Types of Diabetes: Type 1 and Type 2
There are two main types of diabetes. Type 1 diabetes is an autoimmune disease where the immune system destroys insulin-producing cells in the pancreas. It usually develops in genetically susceptible individuals and can be influenced by environmental factors like viral infections and diet 589. Type 2 diabetes is more common and is often linked to risk factors such as age, obesity, low physical activity, high blood pressure, and genetic predisposition. In Type 2, the body either becomes resistant to insulin or does not produce enough .
Prevalence and Global Burden
Diabetes is a growing global health problem, with the number of people affected rising every year. It is estimated that more than 30 million people in the United States (about 9.4% of the population) have diabetes . In Korea, about 14.4% of adults aged 30 and older had diabetes in 2016 . Globally, the number of people with diabetes is expected to reach over half a billion in the coming decades 1346. The disease is a major cause of severe illness and death worldwide 14.
Symptoms and Complications
Common symptoms of diabetes include frequent urination, excessive thirst, unexplained weight loss, fatigue, and increased susceptibility to infections. If not managed well, diabetes can lead to serious complications such as heart disease, kidney failure, nerve damage, vision loss, and increased risk of infections 379.
Management and Control
Managing diabetes involves monitoring blood sugar levels, following a healthy diet, regular physical activity, and often taking medication or insulin. However, many people with diabetes struggle to achieve good control of their blood sugar, blood pressure, and cholesterol. For example, in Korea, only 8.4% of people with diabetes had good control of all three targets (blood sugar, blood pressure, and cholesterol) . Early treatment and patient education are crucial to prevent complications and improve quality of life 376.
Awareness and Education
Despite the high prevalence, many people are unaware they have diabetes or are at risk. Education about the disease, its symptoms, and management is essential for both patients and the general public. Increased awareness can lead to earlier diagnosis, better management, and reduced complications 367.
Conclusion
Diabetes is a widespread and serious health issue that continues to grow globally. It is caused by problems with insulin production or function, leading to high blood sugar levels. The disease can cause many complications if not managed properly, but early detection, lifestyle changes, and proper treatment can help control it. Raising awareness and improving education about diabetes are key steps in reducing its impact on individuals and society 1346+2 MORE.
