Final answer:
Diabetes mellitus is a multifactorial disorder characterized by hyperglycemia due to either insufficient insulin production or a reduced response to insulin, requiring a combination of lifestyle changes, blood-sugar monitoring, and possibly medications.
Step-by-step explanation:
Diabetes is a multifactorial disorder characterized by the body's inability to regulate blood glucose levels effectively. People with diabetes experience elevated blood sugar due to either insufficient insulin production or cells' decreased responsiveness to insulin. Type 2 diabetes is considered a multifactorial disorder because it involves a combination of insulin resistance and impaired insulin secretion, leading to high levels of blood glucose over time.
Diabetes mellitus includes type 1 and type 2 diabetes, both caused by issues with the pancreatic hormone insulin. Symptoms such as excessive thirst, frequent urination, increased hunger, abnormally high blood glucose levels, or hyperglycemia, are indicative of this condition. While treatment often involves lifestyle changes, blood-sugar monitoring, and possibly insulin injections, medications that enhance pancreatic function are also available.
