Type 2 diabetes is the most common form of diabetes and usually develops gradually, although it can occur in younger people as well.

BIMARIDUR HEALTH ENCYCLOPEDIA
Type 2 Diabetes
Type 2 diabetes is a chronic metabolic condition in which the body becomes resistant to insulin and, over time, may not produce enough insulin to maintain normal blood glucose.
ICDE11.9
Affected areaPancreas; liver; muscles; blood vessels; eyes; kidneys; nerves; heart and feet.
ContagiousnessNot contagious.
01 • QUICK UNDERSTANDING
What is Type 2 Diabetes?
02 • BODY & MECHANISM
What happens in the body?
Body structure involved
The pancreas produces insulin, while liver, muscle and fat tissues respond to insulin and influence blood-glucose regulation.
How it starts
Insulin resistance usually develops first, followed by increasing difficulty of pancreatic beta cells to maintain adequate insulin secretion.
What happens inside the body
Body tissues become less responsive to insulin and the pancreas initially compensates by producing more insulin. Over time, beta-cell function may decline, leading to persistent high blood glucose.
03 • TYPES & CLASSIFICATION
Types and classification
Type 2 diabetes is characterized by insulin resistance with progressive beta-cell dysfunction and is distinct from autoimmune type 1 diabetes.
Type 2 diabetes is a major diabetes category distinct from type 1 diabetes, gestational diabetes and secondary forms.
04 • SYMPTOMS
Symptoms and warning signs
Increased thirst
Increased hunger
Fatigue
Blurred vision
Slow-healing wounds
Frequent infections
Numbness or tingling
06 • CAUSES
What can cause this disease?
Type 2 diabetes results from a combination of genetic susceptibility, insulin resistance, progressive beta-cell dysfunction and environmental factors.
07 • RISK FACTORS
Who may have a higher risk?
1
Overweight or obesity
2
Family history of type 2 diabetes
3
Prediabetes
4
Physical inactivity
5
Increasing age
6
History of gestational diabetes in the mother
7
Certain ethnic and genetic risk factors
08 • DIAGNOSIS
How is Type 2 Diabetes diagnosed?
HbA1c, fasting plasma glucose, oral glucose tolerance testing or random plasma glucose with classic symptoms can establish the diagnosis.
Clinical evaluation
Weight and BMI
Blood pressure
Foot examination
Cardiovascular risk assessment
Eye screening according to recommendations
Kidney risk assessment
Laboratory tests
HbA1c
Fasting plasma glucose
Oral glucose tolerance test
Random plasma glucose when symptomatic
Urine albumin-to-creatinine ratio
Serum creatinine and estimated kidney function
Lipid profile
Imaging and scans
Retinal imaging or photography for diabetic eye screening
Vascular or other imaging when a specific complication is suspected
Special or confirmatory tests
Urine albumin testing
Retinal examination
Neuropathy assessment
Foot risk assessment
Cardiovascular risk evaluation

10 • EXTENT / STAGE
Stages or severity
Common clinical progression includes insulin resistance, prediabetes and established type 2 diabetes, followed by possible development of chronic complications.
Important:
Staging or grading systems differ between diseases. The information here is educational and should be interpreted by a qualified healthcare professional in the context of the individual case.
11 • TREATMENT
How is Type 2 Diabetes treated?
Lifestyle intervention is foundational. Medicines may include metformin or other glucose-lowering therapies selected according to glucose levels, cardiovascular and kidney status, weight goals and individual factors.
Medicines that may be used
Metformin
GLP-1 receptor agonist or related incretin-based therapy when appropriate
SGLT2 inhibitor when appropriate
DPP-4 inhibitor when appropriate
Sulfonylurea in selected patients
Insulin when indicated
Medicine safety:
Medicines listed here are for educational information only. Do not start, stop, or change a medicine without professional medical advice.
12 • COMPLICATIONS
Possible complications
Heart disease, stroke, kidney disease, retinopathy, neuropathy, foot ulcers, infections and other vascular complications.
URGENT SAFETY INFORMATION
When should urgent medical help be considered?
Severe hypoglycemia with confusion, seizure or loss of consciousness.
Very high glucose with dehydration or altered mental status.
Persistent vomiting or severe illness with suspected metabolic decompensation.
Severe chest pain, stroke symptoms or other acute cardiovascular warning signs.
If symptoms are severe, rapidly worsening, or life-threatening, seek emergency medical care immediately.
13 • OUTLOOK
Prognosis and recovery outlook
Good glucose, blood-pressure and lipid management can reduce the risk of complications. Earlier diagnosis and sustained treatment improve long-term outcomes.
How to interpret these statistics
Survival statistics describe outcomes in groups of people and cannot predict exactly what will happen to one individual. Prognosis depends on factors such as cancer stage, tumor biology, treatment response, overall health, and follow-up.
14 • EPIDEMIOLOGY
How common is it?
Type 2 diabetes accounts for the majority of diabetes cases worldwide and is increasingly recognized in younger adults and adolescents.
15 • PREVENTION
Risk reduction and prevention
Healthy eating, regular physical activity, weight management and treatment of prediabetes can reduce or delay risk.
