What is type 2 diabetes?
Type 2 diabetes is a chronic condition where the body becomes resistant to insulin or doesn't produce enough. About 11% of US adults have it; another 38% have prediabetes.
Untreated, diabetes damages blood vessels, nerves, eyes, kidneys, and heart. Well-managed, life expectancy and quality of life are excellent. Newer medications (GLP-1 agonists like semaglutide) are highly effective both for blood sugar and weight.
Do I have type 2 diabetes? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Insulin resistance from obesity, genetics, age, physical inactivity, certain ethnic backgrounds, gestational diabetes history, PCOS. Some medications (steroids, antipsychotics) raise risk.
Is it contagious?
No.
Newer medications (especially GLP-1s and SGLT2s) don't just lower sugar — they protect heart and kidneys independently. The era of 'just metformin' is over for many patients.
Can it be treated online?
Established type 2 diabetes is well-suited to telehealth follow-up. New diagnoses benefit from in-person evaluation, full lab workup, and education. Type 1 diabetes, severe complications, or pregnancy with diabetes need in-person specialty care.
How type 2 diabetes is treated
Metformin first-line for most. GLP-1 agonists (semaglutide/Ozempic, liraglutide/Victoza, tirzepatide/Mounjaro) excellent for A1c and weight. SGLT2 inhibitors (empagliflozin, dapagliflozin) lower A1c and protect heart/kidneys. Insulin for advanced disease. Lifestyle always central.
Self-care while you wait
- Carb-aware eating — Mediterranean or low-carb works
- Exercise 30 min most days — even walking helps
- Lose excess weight — 5–10% weight loss substantially improves control
- Monitor blood sugar as advised
- Foot inspection daily
- Annual eye exam
- Quit smoking
- Manage BP and cholesterol aggressively
How long does it last?
Chronic but very modifiable. Some early cases with significant weight loss go into remission.
Frequently asked questions
Can type 2 diabetes be reversed?
Some early cases — with substantial weight loss (often 15+ lbs) and lifestyle change, blood sugar can normalize without medication. This is 'remission,' not cure — relapse is possible.
Is metformin enough?
For many people in the first few years, yes. As disease progresses, additional medications are usually needed.
What about Ozempic for diabetes?
GLP-1 agonists like semaglutide are excellent for type 2 diabetes — they lower A1c, promote weight loss, and reduce cardiovascular events.
Do I really need to test my blood sugar?
Depends on regimen. People on insulin need frequent testing; metformin-only patients may need only A1c every 3–6 months.
Will my kids get it?
Risk is elevated with family history. Healthy weight, activity, and diet substantially reduce risk.
