ConditionICD-10: E11.9

Type 2 Diabetes

A chronic condition affecting how the body processes blood sugar (glucose).

Key facts

•37.3 million Americans have type 2 diabetes (CDC)
•GLP-1 medications lower A1c by 1–2% and aid weight loss
•Ozempic, Mounjaro, Trulicity, Rybelsus are FDA-approved for T2D
•Most commercial insurance plans cover GLP-1 for diabetes (vs weight loss)
•Newer GLP-1s offer cardiovascular benefits beyond glucose control

Why GLP-1 medications

GLP-1 agonists enhance glucose-dependent insulin secretion and suppress glucagon, lowering blood sugar without high hypoglycemia risk. Recent CVOT trials (LEADER, SUSTAIN-6, REWIND, SURPASS-CVOT) show cardiovascular benefits in T2D patients with established heart disease.

Common symptoms

Frequent urination, especially at night
Increased thirst and dry mouth
Unexplained weight loss or weight gain
Fatigue and irritability
Blurred vision
Slow-healing cuts, frequent infections
Numbness or tingling in hands and feet (later stage)

How type 2 diabetes is diagnosed

Diagnosis requires one of: A1c ≥ 6.5%, fasting plasma glucose ≥ 126 mg/dL, 2-hour oral glucose tolerance test ≥ 200 mg/dL, or random glucose ≥ 200 mg/dL with classic symptoms. Diagnosis should be confirmed with repeat testing unless symptoms are obvious. A1c reflects 3-month average glucose; ideal target is generally < 7% for most adults.

Treatment options

Metformin (first-line)

Cheap, well-tolerated, reduces glucose production by liver. A1c reduction: 1–2%. Used in 80% of T2D patients.

GLP-1 agonists

Ozempic, Trulicity, Mounjaro, Rybelsus. A1c reduction: 1–2% + weight loss + CVD risk reduction. Now ADA-recommended for T2D with established CVD or high CVD risk.

SGLT2 inhibitors

Jardiance, Farxiga, Invokana. Cause kidney to excrete excess glucose in urine. Cardiovascular and renal benefits.

Insulin

Used when other meds insufficient, or in newly-diagnosed patients with very high A1c (>10%). Long-acting (basal) + rapid-acting (mealtime).

Lifestyle & self-care

Mediterranean diet — emphasizes vegetables, whole grains, fish, olive oil
Limit added sugars and refined carbs
Exercise 150+ min/week aerobic + 2x/week resistance training
Lose 5–10% of body weight if overweight (can put T2D in remission for some)
Don't smoke — tobacco accelerates diabetic complications
Annual eye, kidney, and foot exams

When to see a doctor

Make an appointment if you have:

→Frequent urination, thirst, fatigue (especially with family history)
→BMI ≥ 25 with sedentary lifestyle
→Family history of T2D, gestational diabetes
→High blood pressure or abnormal cholesterol
→Age ≥ 45 (annual screening recommended)
