Newly Dx’d T2DM – Need Advice

Hey all, Got a 47 y/o F who came in post-screening. Random glucose at the event was 227 mg/dL (12.6 mmol/L), so I did a fasting BG – came back 147 mg/dL (8.2 mmol/L). No hx of DM, but she’s overweight and pretty sedentary. Couple Qs: Dx Confirmation: Would you do a repeat FBG or jump straight to HbA1c? Lifestyle Rx: Any solid resources/tools for diet/exercise that pts actually stick to? Bonus if they’re simple and patient-friendly. Meds: Start metformin right away or give lifestyle changes a trial first? If metformin, anything specific to check besides Cr and LFTs? Endo Referral: When would you loop in an endo? Early on to set the tone or wait and see if things stabilize? Thanks!
