Top Diabetes Treatment Advancements in 2023

If you live with diabetes (or love someone who does), 2023 probably felt like the year your devices got smarter,
your meds got more “multi-tool,” and your doctor started talking about time in range like it’s the new
gold standard (because… it kind of is). We didn’t get a magic “cure” buttonscience doesn’t work like a movie
montagebut 2023 delivered real, practical leaps in how diabetes is treated day-to-day.

This guide breaks down the biggest diabetes treatment advancements from 2023what they are, why they matter,
who they may help, and how they’re changing real-world care. (Friendly reminder: this is educational info,
not personal medical advice. Your clinician should always have the final say on your treatment plan.)

Why 2023 Was a Standout Year for Diabetes Care

Diabetes treatment isn’t just about lowering glucose anymore. In 2023, the “best” therapies increasingly did
more than one job:

• Technology got closer to “set it and forget it” automation for insulin dosing.
• Continuous glucose monitoring (CGM) became easier to accessand more central to care.
• Medications kept moving toward weight, heart, and kidney benefits alongside glucose control.
• Cell therapy took a major regulatory step forward for a specific group of people with type 1 diabetes.

Think of it like this: 2023 wasn’t one single breakthroughit was a stack of meaningful upgrades that make diabetes
management less exhausting and, for many people, safer.

1) Automated Insulin Delivery Got More “Hands-Off”

Automated insulin delivery (AID) systemsoften called “closed-loop” or “hybrid closed-loop”kept improving in 2023.
The goal is simple: help people spend more time in their target glucose range with fewer highs, fewer lows, and fewer
mental math equations before breakfast.

The iLet Bionic Pancreas System: A New Style of Automation

In 2023, the FDA cleared key components of the Beta Bionics iLet Bionic Pancreas system for people
ages 6 and older with type 1 diabetes. One headline feature: the iLet approach is designed to reduce the burden of
traditional fine-tuning by using an algorithm-driven dosing strategy (paired with a compatible CGM).

Translation: it aims to do more of the “thinking” for youso you can spend less time micromanaging insulin delivery
and more time being a person with hobbies.

Medtronic MiniMed 780G: More Aggressive Auto-Corrections

Another major 2023 milestone was expanded FDA approval for the MiniMed 780G system for people
(generally) ages 7+ with type 1 diabetes. The big idea here is tighter automationmore frequent auto-corrections,
more help smoothing glucose swings, and improved sensor integration.

Interoperability, Remote Updates, and the “Ecosystem” Era

Behind the scenes, 2023 continued the trend toward diabetes tech behaving more like modern software:
updates, device compatibility, and systems built to work together. That matters because diabetes isn’t a single device
problemit’s a full-time logistics problem. The more seamlessly tools connect, the fewer “Why is nothing talking to
anything?” moments you have at 2 a.m.

2) CGMs Became More Accessible (Which Is a Treatment Upgrade)

A CGM isn’t just a gadgetit’s treatment support. It changes decision-making in real time: meals, activity, sleep,
illness, stress, and medication adjustments. In 2023, access improved in a big way, and that is a clinical advancement,
not a convenience perk.

Medicare Coverage Expanded in 2023

In 2023, Medicare eligibility for CGM broadened, including more flexibility for insulin-treated individuals and
expanded pathways for some people not taking insulin who have a history of problematic hypoglycemia. That change
matters because affordability and coverage rules often decide who gets the best toolsnot medical need alone.

Next-Gen Sensors and Better Wearability

CGM improvements were also about everyday usability: smaller profiles, simpler insertion, shorter warm-up times,
and more smartphone-friendly workflows. These features can sound “minor” until you remember the device is on your body
nearly every day. Comfort and simplicity directly affect whether people stick with a tool long-term.

Time-in-Range Became a Main Character

More clinicians and patients used CGM metricsespecially time in rangeto guide care in 2023.
Instead of focusing only on A1C (an average), time in range shows what daily life really looks like: spikes, dips,
overnight lows, post-meal climbs, and how often you’re where you want to be.

3) Medications Kept Evolving into “Metabolic Multi-Tools”

For type 2 diabetes, 2023 continued a shift away from “glucose-only” thinking. Many modern diabetes medications also
target weight, cardiovascular outcomes, and kidney protection. That’s not marketing fluffthose complications are what
make diabetes dangerous over time.

GLP-1 and Dual-Incretin Therapies: More Than Lowering Sugar

GLP-1 receptor agonists and dual-incretin therapies (like GLP-1/GIP combinations) remained a major force in 2023.
They can improve glucose control and often support meaningful weight loss, which can reduce insulin resistance and
improve cardiometabolic risk factors for many people with type 2 diabetes.

Practical example: someone who has struggled with post-meal spikes, weight gain, and rising A1C might benefit from a
medication class that helps appetite regulation and glucose controlpotentially reducing the need for escalating doses
of insulin that can sometimes increase weight.

Retatrutide: A Glimpse of What’s Next

2023 also brought attention to newer investigational medicines aiming to activate multiple hormone receptors involved
in metabolism. Retatrutide (a triple-hormone-receptor agonist) drew notice in clinical research because it showed
substantial weight loss effects in trials, including among participants with type 2 diabetes. It’s not a routine
diabetes prescription todaybut it’s a preview of where pharmacology is heading.

SGLT2 Inhibitors and Organ Protection: The “Standard That Keeps Getting Stronger”

SGLT2 inhibitors continued to be central for many people with type 2 diabetesespecially those with chronic kidney
disease or heart failure riskbecause they’re used not only for glucose management but for risk reduction. In modern
diabetes care, protecting kidneys and hearts is not optional; it’s part of the treatment mission.

4) Once-Weekly Insulin Became Much More Real in 2023

Daily basal insulin works, but it demands relentless consistency. Missed doses can cause runaway glucose. And for many
people, the daily routine is a major barrierespecially when life is busy, unpredictable, or already medically complex.

Insulin Icodec: Phase 3 Evidence and the Promise of Simplicity

In 2023, once-weekly insulin icodec produced high-profile phase 3 trial results in type 2 diabetes, showing strong
glycemic control compared with daily basal insulin comparators in studied groups.

What once-weekly insulin could change:

• Adherence: fewer “oops, I forgot” moments across a week.
• Routine burden: fewer injections can reduce burnout for some people.
• Care planning: weekly dosing could pair naturally with weekly coaching or check-ins.

The important nuance: longer-acting insulin strategies can raise safety questions, especially around hypoglycemia risk
and dose adjustment. Weekly insulin is excitingbut it must be used carefully with patient education, monitoring, and
individualized dosing plans.

5) Cell Therapy Hit a Major Regulatory Milestone for Type 1 Diabetes

For type 1 diabetes, insulin remains essential. But 2023 delivered a landmark step toward treatment options that could
reduce dependence on injected insulin for a very specific subgroup of patients.

Lantidra (Donislecel): First FDA-Approved Donor Islet Cell Therapy

In June 2023, the FDA approved Lantidra (donislecel), the first allogeneic pancreatic islet cellular
therapy made from deceased donor cells, for adults with type 1 diabetes who struggle with repeated severe hypoglycemia
despite intensive management and education.

This is not “a cure for everyone.” It’s a targeted therapy for people with dangerous low blood sugar eventsespecially
when they happen unpredictably. It can require immunosuppression, and it’s limited by donor cell availability, but it
represents a major clinical and regulatory milestone: type 1 diabetes treatment expanding beyond insulin and devices.

Stem Cell–Derived Islet Therapies: Still Experimental, Still Encouraging

2023 also featured ongoing updates and public attention around experimental therapies using stem cell–derived
insulin-producing cells. Some early clinical programs reported improved glucose control and reduced insulin needs in
participants, pointing toward a future where insulin replacement could be biologic rather than mechanical.

The hurdles are real: immune protection, durability, safety, manufacturing scale, and equitable access. But 2023 helped
make cell therapy feel less like science fiction and more like a developing treatment category.

6) Treatment Became More Personalized and Outcome-Focused

Another 2023 “advancement” wasn’t a single device or drugit was a clearer strategy: match treatment to the outcomes
that matter most for each person.

From A1C-Only to “A1C Plus Time-in-Range Plus Safety”

A1C remains important, but it’s not the whole story. Two people can have the same A1C and totally different lives:
one with constant swings and frequent lows, another with stable readings. In 2023, CGM-driven management strengthened
the push toward stability, safety, and quality of lifenot just averages.

Diabetes Care That Also Treats the Heart and Kidneys

For many people with type 2 diabetes, the “best” treatment plan isn’t the one that produces the lowest glucose number
on a single dayit’s the one that lowers long-term risk of kidney decline, cardiovascular events, and hospitalizations.
Medication choices increasingly reflect that reality.

Coaching, Telehealth, and Digital Support

Diabetes care in 2023 also leaned harder into remote support: CGM data review, virtual visits, smart insulin pens,
and app-based education. This can be especially helpful for people who don’t have easy access to endocrinology care or
need frequent adjustments early in treatment.

What to Do With This Information (A Practical 2023-Inspired Checklist)

If you’re trying to translate “advancements” into real life, here are questions worth discussing with your clinician:

• Would a CGM improve safety (especially overnight) or decision-making for me?
• Am I a candidate for an automated insulin delivery system, and which one fits my lifestyle?
• For type 2 diabetes: would a GLP-1, dual-incretin, or SGLT2 inhibitor make sense given my heart/kidney risk?
• If I use basal insulin (type 2): what’s the evidence and timeline for once-weekly insulin options, and would it be appropriate?
• If I have type 1 diabetes with severe hypoglycemia: should I ask about specialty evaluation for advanced therapies?

The best advancements are the ones you can actually useaffordably, safely, and consistently.

Conclusion: 2023 Made Diabetes Treatment Smarter, Broader, and More Human

The story of 2023 is not “one miracle.” It’s progress in multiple lanes: automated insulin delivery that reduces daily
workload, CGMs that became more accessible, medications that protect more than glucose, and cell therapy that reached a
new milestone for certain high-risk type 1 diabetes patients.

If diabetes management sometimes feels like juggling while walking a tightrope2023 didn’t remove the tightrope, but it
did add a safety net, a better balancing pole, and (finally) fewer flaming torches.

Real-World Experiences (About ): What These 2023 Advancements Feel Like in Daily Life

Clinical trials and FDA announcements are important, but diabetes is lived one meal, one commute, one exam, one night
of sleep at a time. Here are common real-world experiences people report when newer 2023-era tools and strategies enter
the picture. These are illustrative examples based on themes frequently discussed in clinical care and
diabetes communitiesnot one person’s story and not medical advice.

1) The “I Can Sleep Again” Moment (CGM + Alerts)

For many families and individuals, CGM alerts are emotionally huge. People describe the first week with a CGM as a mix
of relief and annoyance: relief because overnight lows are less mysterious, annoyance because the body apparently has
opinions at 3:17 a.m. Over time, the experience often shifts toward confidenceespecially when alerts are personalized
(not too sensitive, not too quiet). The advancement isn’t just a number on your phone; it’s the ability to plan sleep
without fear.

2) Less Mental Math, More Normal Life (Automated Insulin Delivery)

People who move into AID systems often talk about “brain space.” Instead of constantly predicting what food and
activity will do, they can check in, confirm, and move on. It’s not perfectmeals can still spike, and infusion sets
can still misbehave like tiny drama queensbut the daily load feels lighter. Many describe it as going from “manual
transmission” to “assisted driving.” You’re still responsible, but you’re not alone.

3) The Learning Curve Is Real (And That’s Normal)

New tech can bring new stress: alarms, calibration questions, adhesive issues, or “Why is my sensor reading different
than my fingerstick?” In 2023, better training and more clinician familiarity helped, but people still benefit from
realistic expectations: the first month is often a setup-and-tweak phase. The best outcomes show up when users
personalize alert thresholds, understand trend arrows, and learn what patterns their body repeats (because yes, your
glucose has favorite habits).

4) Medication Changes Can Feel Like Identity Changes

For type 2 diabetes, adding a GLP-1–based medication or newer combination therapy can change appetite, portions, and
cravings. Some people feel empowered“I finally don’t feel hungry all day”while others need time to adjust to side
effects or a new relationship with food. When it works well, patients often describe improvements that go beyond
glucose: less post-meal fatigue, more energy for walking, and a sense that their body is cooperating again.

5) Access and Coverage Are Part of the Experience

Many people experience “treatment advancement” as paperwork first: insurance forms, pharmacy shortages, and prior
authorizations. That’s why 2023 coverage expansions for CGM mattered so muchbecause an innovation is only real when
you can actually get it. People frequently report that once access barriers drop, adherence improves naturally: it’s
easier to use tools when you’re not rationing sensors or stressing about costs.

The honest takeaway: 2023 advancements didn’t just improve medical optionsthey improved the lived experience
of managing diabetes. And for a condition that requires daily effort, that’s not a small win. It’s the whole point.
