My dad was just diagnosed with diabetes. What do we do now?

Your first job: the first weeks

A diabetes diagnosis feels like a wall of new rules, but you have time and the basics are learnable. Get a few things moving now.

• Ask for a referral to a diabetes educator and a dietitian (it's called DSMES). It's proven to help and most families never hear about it, so ask at diagnosis, when it helps most.
• Learn the two things that matter first: how he'll eat (the plate method, below) and how to spot and treat a low blood sugar.
• Set up simple monitoring and one shared record (readings, medicines, questions). Ask whether a continuous glucose monitor (CGM) is a good fit.
• Pick one family point person, and bring his full medication list to every appointment.

The diagnosis: things to consider

The main number is the A1C, a blood test that reflects the average blood sugar over about three months (diabetes is diagnosed at 6.5% or higher). One A1C is an average, not a single day, which is why it and a home reading can differ. At his age this is almost certainly Type 2, the common kind, and the target is set for him: often looser for an older adult, on purpose, to avoid dangerous lows.

On treatment, food and activity are the foundation from day one. Metformin is the usual first medicine; newer drugs (the GLP-1 and SGLT2 classes) can also protect the heart and kidneys; and some people need insulin. For an older parent, simpler and gentler is often safer, and doctors will sometimes scale a regimen back rather than up.

Before you leave the appointment, ask about these

• What A1C target they're aiming for, given his age and health.
• Which of his medicines can cause low blood sugar, and what to watch for.
• A referral to a diabetes educator and a dietitian.
• Whether a continuous glucose monitor is a fit, especially one that can alert the family.

The road ahead

Diabetes is cared for over years, and this is where the family really helps. Here's the job, as a checklist, starting with the biggest lever you have.

Food, together (the biggest lever)

• Use the plate method: on a 9-inch plate, fill half with non-starchy vegetables, a quarter with lean protein, and a quarter with high-fiber carbs (whole grains, beans, fruit). No scale, no math; the plate does the portions.
• There's no such thing as "diabetic food." Cook one healthy meal the whole family eats. It drops the stigma, and it's good for everyone at the table.
• The easiest high-impact change: swap soda and juice for water, plain coffee, or unsweetened tea. Sugary drinks hit blood sugar hardest.
• Cook with him, not for him, and skip the "food police" role. Nagging backfires and adds stress; let the dietitian do the teaching.

Set up monitoring and medicines

• A glucose meter, or a CGM that shares readings to your phone with low alerts (a real safety net if he lives alone).
• One clear medication routine (an organizer, refill reminders). Keep fast-acting sugar where he'll need it, and know where any glucagon kit is. That med list and schedule are what Greenlue keeps in one place.

Sort the paperwork (while it's calm)

• A healthcare proxy, a financial power of attorney, and a HIPAA authorization (free forms: AARP, CaringInfo). It's routine planning, easiest done early.
• Keep those, the diagnosis, and his records in one place the family can reach. That's what Greenlue holds, so there's no binder to hunt for.

Know what to watch for

The one thing every family should catch fast is a low blood sugar, most likely if he takes insulin or certain pills. Here's how the American Diabetes Association describes it:

The ADA's rule for a mild low: give 15 grams of fast sugar (4 oz of juice or regular soda, or glucose tablets), wait 15 minutes, and recheck. If he can't swallow, passes out, or has a seizure, it's severe: give glucagon if you have it and call 911, and never put food in the mouth of someone who can't safely swallow. Go by his own team's plan.

His day to day

• Keep the routine: regular meals, some activity most days, medicines on time, and the yearly checks that catch trouble early, a dilated eye exam, a foot exam, and kidney labs.
• Check his feet with a quick daily look for cuts, blisters, or red spots, since nerve damage can hide an injury. Ask the team about the right footwear.
• Watch mood. Depression and "diabetes distress" are common and treatable, so mention low mood early.
• Get a sick-day plan from the team before you need it, and know that a very high reading with confusion or heavy thirst in an older adult needs a same-day call.

What he'll need from you, and protecting yourself

• Rides to appointments, help keeping the routine, and steady, non-judgmental encouragement.
• Carry an accurate medication list to every visit and hospital stay; mix-ups are common and risky on diabetes drugs.
• Split roles with siblings, and use FMLA if you work (up to 12 weeks, job-protected, a few hours at a time).
• Look after yourself too; a burned-out caregiver helps no one, and this is a long game.

Nearly all of it is coordination
