Diabetes.

Overview

Diabetes is a group of conditions characterized by elevated blood glucose. Type 1 and type 2 diabetes differ in cause and management, and gestational diabetes develops during pregnancy.

A condition may appear differently between people, so a symptom list alone cannot establish a diagnosis. Age, medical history and other circumstances affect assessment.

Signs and symptoms

Possible symptoms of high blood glucose include frequent urination, unusual thirst, fatigue, blurry vision and unintended weight change. Some people have few noticeable symptoms, while type 1 diabetes may develop relatively quickly. Recurrent infections or slow wound healing can also prompt assessment; only appropriate clinical testing can confirm diabetes.

Causes and risk factors

Type 1 involves autoimmune loss of insulin-producing cells; type 2 involves insulin resistance and impaired insulin secretion among other factors.

Risk factors do not guarantee that a person will develop this condition, and a diagnosis can occur even without obvious risk factors.

Diagnosis and tests

Blood tests including HbA1c or glucose measurements are used for diagnosis according to clinical criteria.

Tests are chosen for the individual situation. No picture or AI-generated response can confirm this condition.

Care and treatment

Management may involve nutrition planning, physical activity, glucose monitoring and medicines or insulin tailored to the type.

Treatment plans must consider severity, other illnesses, medication safety and personal preferences. Do not start or change prescribed treatment using this article alone.

Prevention and daily living

Learn the signs of high and low glucose, maintain regular clinical checks, follow a suitable eating and activity plan, and discuss foot, eye, kidney and cardiovascular monitoring appropriate to your diabetes type.

Individual care plans may differ, particularly in pregnancy, childhood, older age or when other illnesses are present. The linked clinical source provides more context.

When to seek help

Confusion, vomiting, deep rapid breathing, severe dehydration or symptoms of dangerously low glucose need urgent care.

If symptoms are severe, rapidly worsening or you feel unsafe, seek local emergency services. Do not wait for an online reply.

Questions for a clinician

What evidence supports this diagnosis? What tests are necessary? Which treatment options fit my situation? What should I monitor? When should I return or seek urgent help?
