What is diabetes mellitus?
Diabetes mellitus is a chronic condition where the body struggles to maintain blood glucose levels due to insufficient insulin (Type 1 diabetes) or insulin resistance (Type 2 diabetes). Insulin is crucial for moving blood glucose into cells, so when its function is impaired, this results in high blood sugar, which leads to various health complications. Effective diabetes management often includes a structured diabetes mellitus care plan to stabilize blood glucose and prevent further issues.
Causes of diabetes mellitus
The causes of diabetes mellitus vary, with different risk factors affecting blood glucose regulation:
Type 1 diabetes
In Type 1 diabetes, an autoimmune response damages the insulin-producing cells, leading to low insulin levels and poor blood glucose control. Genetic factors and certain viral infections are key risk factors. Managing this type often requires insulin injections to maintain target blood glucose levels.
Type 2 diabetes
Type 2 diabetes is marked by insulin resistance, making it difficult for cells to use insulin effectively. Key risk factors include obesity, sedentary lifestyle, and genetics. Diabetes management for Type 2 focuses on blood glucose monitoring, lifestyle adjustments, and sometimes medication to reduce associated risks, such as cardiovascular disease.
Gestational diabetes
Gestational diabetes arises during pregnancy due to hormone changes that heighten insulin resistance. Risk factors include obesity and advanced maternal age, making blood glucose control critical to minimize risks to both mother and child.
Symptoms of diabetes mellitus
Recognizing diabetes symptoms early helps maintain blood glucose levels and reduce complications.
- Common symptoms: Frequent urination, excessive thirst, hunger, unintended weight loss, and fatigue are expected as the body attempts to manage excess blood glucose.
- Other symptoms: Diabetes can cause blurred vision, slow-healing wounds, and tingling or numbness, often due to poor circulation and nerve function.
