A1C reflects your average blood sugar over 2-3 months, so doctors set personalized targets, often aiming for <7% to reduce complications, but potentially lower for younger individuals or higher for older adults.

While some can stop with lifestyle changes (diet, exercise, weight loss) or if diabetes goes into remission, others need it lifelong; doctors monitor kidney function and Vitamin B12 levels, which can drop with long-term use, and may suggest alternatives or supplements. 

What is the life expectancy of a person with type 2 diabetes?

Type 2 diabetes can shorten life expectancy, often by several years, but this varies greatly; a diagnosis at age 50 might reduce life expectancy by about 6 years, while a diagnosis at 30 could mean up to 14 years lost, though good management (blood sugar, BP, cholesterol, weight, no smoking) can significantly improve this, potentially adding years back or even surpassing non-diabetic lifespans in some cases.

Metformin is widely considered the safest first-line medication for Type 2 diabetes due to its effectiveness, affordability, long history, and weight-neutral profile, though it can cause GI issues. Newer drugs like GLP-1 agonists (e.g., semaglutide) and SGLT2 inhibitors (e.g., Jardiance, Farxiga) offer added heart, kidney, and weight loss benefits, while alpha-glucosidase inhibitors are also very safe as they work locally in the gut. The "safest" choice depends on individual health factors, so consulting a doctor is essential.
 

Why switch from metformin to Jardiance?
