Type 2 Diabetes
Also known as: T2D, Adult-Onset Diabetes, Non-Insulin-Dependent Diabetes, Type 2 Diabetes Mellitus
Type 2 diabetes is a chronic metabolic condition characterized by insulin resistance and relative insulin deficiency, leading to elevated blood sugar levels. It accounts for 90-95% of all diabetes cases and is strongly associated with obesity, physical inactivity, and genetic factors. While type 2 diabetes is a progressive condition, it can often be managed or even put into remission through lifestyle modifications, medications, and regular monitoring.
Symptoms
Causes
- Insulin resistance (cells don't respond properly to insulin)
- Progressive beta-cell dysfunction in the pancreas
- Genetic predisposition
- Excess body fat, especially visceral (abdominal) fat
- Sedentary lifestyle
Risk Factors
- Overweight or obesity (BMI ≥ 25)
- Physical inactivity
- Family history of type 2 diabetes
- Age 45 and older
- African American, Hispanic, Native American, or Asian American ancestry
- History of gestational diabetes or prediabetes
Diagnosis
- HbA1c test (≥6.5% indicates diabetes; 5.7-6.4% indicates prediabetes)
- Fasting plasma glucose (≥126 mg/dL)
- Oral glucose tolerance test (≥200 mg/dL at 2 hours)
- Random plasma glucose (≥200 mg/dL with symptoms)
Treatment
- Lifestyle modifications (healthy diet, regular exercise, weight loss)
- Metformin (first-line oral medication)
- SGLT2 inhibitors (empagliflozin, dapagliflozin) with cardiovascular and renal benefits
- GLP-1 receptor agonists (semaglutide, liraglutide) for glucose control and weight loss
- Other oral agents (sulfonylureas, DPP-4 inhibitors, thiazolidinediones)
- Insulin therapy when oral medications are insufficient
Prevention
- Lose 5-7% of body weight if overweight or obese
- Engage in at least 150 minutes of moderate exercise per week
- Follow a balanced diet emphasizing whole grains, vegetables, and lean protein
- Limit sugary beverages and processed foods
- Get screened regularly if you have prediabetes or risk factors
When to See a Doctor
- You have risk factors for diabetes and have not been screened
- You experience increased thirst, frequent urination, or unexplained fatigue
- Your blood sugar is consistently above target despite medication
- You develop numbness in your feet, vision changes, or slow-healing wounds
