If you are taking the CDCES or BC-ADM exam in 2023, these new lipid targets for high risk individuals and treatment interventions are important to know.
For all of us who serve people with diabetes, evidence from many trials demonstrated that these more intensive LDL cholesterol targets will save lives and decrease CV disease. By sharing this information with our colleagues and teams, we can be a part of improving outcomes and quality of life.
The following content summarizes the 2023 updated ADA guidelines as outlined in Standard 10 – Cardiovascular Disease and Risk Management.
The guidelines have remained the same for lower risk individuals with diabetes aged 40–75 years without atherosclerotic cardiovascular disease, “Start moderate-intensity statin therapy in addition to lifestyle therapy”. They also are the same for people with diabetes aged 20–39 years with additional atherosclerotic cardiovascular disease risk factors, “Based on individual assessment, initiate statin therapy in addition to lifestyle therapy.”
In the category of primary prevention for people with diabetes aged 40–75 at higher cardiovascular risk (LDL >100, HTN, Smoke, CKD, albuminuria, family hx ACSVD), the goals have been intensified.
Secondary Prevention goals have also been intensified.
For people of all ages with diabetes and atherosclerotic cardiovascular disease:
Target LDL cholesterol reduction of 50% or greater from baseline and an LDL cholesterol goal of <55 mg/dL.
Addition of ezetimibe or a PCSK9 inhibitor with proven benefit in this population is recommended if goal is not achieved on maximum tolerated statin therapy.
In 2022, the ADA Standards did not include specific LDL targets for people with diabetes. However, based on recent study results, the committee updated the 2023 guidelines to reflect the latest research findings. To learn more about the study findings, Standard 10 – Cardiovascular Disease and Risk Management.
Keeping track of medications for hypertension and cholesterol can seem daunting. We have put together a Lipid Medication Cheat Sheet along with summary information for each class that is important to know for certification exams and is very useful in clinical practice.
Together, we can improve the quality of life and outcomes for people living with diabetes. Getting LDL cholesterol levels to target is an important interventions to maintain health. Thank you for reading this article and advocating for the best evidence-based care.

The cost of insulin is a real problem. According to an analysis of data from the CDC’s 2021 National Health Interview Survey, 1.3 million Americans with diabetes, or 16.5% of insulin users in the U.S. rationed their insulin in the past year due to the high costs of this life-saving hormone.
Insulin rationing is more common in adults under the age of 65, middle-income individuals, and Black Americans. This lack of insulin results in chronic hyperglycemia, intensifying the risk of diabetes-related complications, worsening quality of life, and can even lead to hospitalization and death.
In the 2021 National Health Survey, 16.5% of respondents living in the US, rationed insulin in the past year.
The retail price for a box of insulin pens (1,500 units) is about $500. A vial of insulin (1000 units) varies from $160 to $400. For this reason, many insulin companies offer coupons or biosimilar versions of certain insulins. However, these cost savings aren’t enough for many individuals.
Hopefully, the 2022 Inflation Reduction Act, will at least improve insulin access for seniors with Medicare by limiting insulin copays to $35 per month. However, a similar cap for the privately insured was removed from the bill, and copay caps do not aid the uninsured. Further reform is needed to improve access to insulin for all Americans.
According to a very compelling article published by USC, the insulin distribution intermediaries, or Pharmacy Benefits Managers (PBMs), are significantly contributing to increasing insulin costs.
A USC cross-sectional study of the U.S. insulin market was conducted in 2020 using 2014-2018 data from multiple sources. The study analyzed the flow of funds throughout the insulin distribution system which includes manufacturers, drug wholesalers, pharmacies, health plans, and (PBMs).
According to the USC study, in 2014, 70% percent of insulin revenue was going to the manufacturers and 30% of the insulin revenue went to the PBM middlemen, but by 2018, only 47% was going to the manufacturers. The intermediaries—mostly PBM’s and pharmacies–were pocketing the rest, a whopping 53% share of the revenue from insulin sales.
In light of this complicated insulin distribution system, more needs to be done to uncover these issues and get to the root of unaffordable insulin for the millions of people who rely on it every day.
Until we get a handle on the cost of insulin, here is some helpful information and programs that can make insulin more affordable.

Walmart and some other pharmacies also offer ReliOn insulins. These include Novolin R, Novolin N, and Novolin 70/30. For people with type 2 diabetes and some with type 1, these insulins offer an affordable option. They are only $25/vial or $44/5 pack of pens and do not require a prescription in most states. Access to these insulins can be truly life-saving in some circumstances. Every person with diabetes needs to be aware that they can purchase these insulins without a prescription if they are ever out of insulin.
Because insulin is a biologic drug, a true generic must come from the same manufacturer. Recently Lilly and Novo Nordisk have created generic insulins.
Lilly offers generics of insulin lispro, insulin lispro mix 75/25, and insulin lispro junior kwik pen.
Novo Nordisk offers generics of their insulin, which they are calling a “follow on Brand” and includes insulin apart and insulin Aspart mix 70/30.
Both Lilly and Novo offer approximately 50% cost savings from the original insulin product and the pharmacist can make an automatic substitution if you ask.
Most insulins offer a co-pay card which can bring down the price of insulin most commonly to $0 to $25/month depending on the manufacturer and type of insulin. For any person with a commercial insurance plan, it’s good to check if a co-pay card is available for the insulin before picking it up from the pharmacy.
The things to be aware of about these cards are that they have maximum savings and sometimes that is much less than the total cost of the insulin. Also, they only work for people with commercial insurance meaning they won’t for people without health insurance or that have a government insurance plan like Medicare. They also do not always work if the drug is not covered by the insurance plan. In that case, it would be preferable to switch to insurance covered by the insurance plan.
These are programs offered through pharmaceutical companies for people without health insurance or that have Medicare but still struggle to pay for medications. There are various income requirements to be eligible, but depending on the program it can be 250-400% above the Federal poverty line. Many people are surprised to find that they are eligible, so this is a good option to look into which can make insulin completely free. There is typically a packet of information that needs to be completed and then if eligible, the insulin is shipped to the prescriber’s office for the patient to pick up.
In summary, more needs to be done to make insulin more affordable. As diabetes specialists, we can write to our congresspeople and advocate on behalf of people living with diabetes, to ensure that people no longer have to ration insulin.

LS tells you that they frequently attend company mixers where they feel compelled to have at “least a few drinks”, to fit in and network. The tricky part of this scenario is that LS lives with type 1 diabetes. Since they don’t have a working pancreas, their circulating levels of insulin and glucagon are often mismatched to their body’s needs.
When discussing the situation, LS says they feel confident they can handle alcohol and prevent lows since they have lived with type 1 diabetes for over ten years. LS shares, “I feel comfortable recognizing when both arrows are pointing down and I am heading for a glucose crash”.
As educators, we are committed to taking person-centered approach while encouraging safe practices.
In regards to LS, we realize alcohol’s impact on the thought process and blood glucose levels. We know that alcohol can affect critical thinking and possibly impair recognition of an impending hypoglycemic event. Inebriation also has many symptoms in common with hypoglycemia. Plus, alcohol consumption slows glycogen breakdown in the liver, which increases the risk of hypoglycemia. Lastly, based on a study published in Endocrinology Advisor, higher levels of alcohol in the blood can delay and blunt the effectiveness of glucagon rescue medications.
In the worst-case scenario, if LS experiences severe low blood sugar and passes out, alcohol ingestion can blunt the effectiveness of the glucagon rescue medications.
Alcohol and Glucagon Pathophysiology Review
The body considers alcohol a toxin and as soon as it reaches the bloodstream, the liver prioritizes metabolizing the alcohol and breaking it down. During this clean-up process, the liver is distracted from responding to endogenous glucagon, the hormone that signals the liver to break down glycogen for energy and liberate glucose into the bloodstream. This clean-up can last for up to 8 hours, making delayed hypoglycemia a real possibility.
When a person with type 1 diabetes drink alcohol, they at increased risk of hypoglycemia because the liver isn’t breaking down stored glycogen to increase blood glucose levels.
Let’s get back to LS. What if LS is drinking gin and diet tonics and only munching on low-carb vegetables and cheeses during the mixer? LS is not ingesting many carbohydrates, so glycogen stores may be low and the liver is busy cleaning up the alcohol and blood sugars start dropping. By the 4th drink, LS isn’t thinking very clearly, says they “feel funny” and passes out.
A colleague of LS carries a glucagon emergency kit and provides LS with a dose and calls 911. After 15 minutes, LS still hasn’t regained consciousness, so a second dose is administered. The paramedics arrive and check the glucose, it is 53.
Simply put, glucagon rescue medications may not work if the person drinks too much alcohol.
After reviewing the package inserts of all available US manufactured Glucagon Rescue Meds, there are no warnings for alcohol intake decreasing the effectiveness of glucagon rescue meds. So, I dug a little deeper and found a decent study on the topic which describes the impact of alcohol ingestion on glucose-regulating hormones.
I also found a very helpful monograph published by Lilly Baqsimi in Canada. Baqsimi is a powdered glucagon rescue medication that is delivered nasally. The Baqsimi monograph clearly states several warnings, “Alcohol can suppress hepatic gluconeogenesis and chronic alcoholism can deplete liver glycogen stores. Therefore BAQSIMI may be less effective in presence of acute or chronic alcohol ingestion. Alcohol-induced hypoglycemia is associated with a failure of blood glucose levels to rise normally after glucagon administration. BAQSIMI may not work if the person drinks too much alcohol.“.
Keeping it Real and Safe
In conclusion, having a conversation with people with type 1 about the suppressive nature of alcohol on glycogen release for many hours after consuming alcohol is very important. Another important teaching point is that glucagon rescue meds may not be as effective and timely in raising glucose to safe levels.
As a general rule of thumb, encouraging people with type 1 to eat 15gms of carbs with each drink and have a glass of water in between, may help make sure they have enough circulating carbs and slow the pace of alcohol consumption to help the liver with processing. They may also consider decreasing their insulin dose in association with alcohol intake to prevent this serious side effect.

We have just added this novel, first in class, dual incretin hormone therapy, Tirzepatide (Mounjaro), to our printed version of our Diabetes Medication PocketCard.
This new twin therapy includes not only a GLP-1 Receptor Agonist, but also a Glucose-dependent insulinotropic polypeptide (GIP), which magnifies the therapeutic effectiveness. The SURPASS studies indicate that study participants experienced an A1C drop of up to 2.5% and weight loss of up to 10kg or more.
Incretins (GLP-1 and GIPs) play a major role in glucose regulation post prandially. Incretins are gut hormones that stimulate insulin release from the pancreas when glucose rises in response to food ingestion. They keep blood sugars in check as well as activating the satiety center, to increase the sense of fullness. Incretins slow gastric emptying and also curb post-meal glucagon release, decreasing post prandial glucose spikes. Unfortunately, people with type 2 diabetes, make less than half of the usual amount of the GLP-1 and GIP hormones, which contributes to chronically elevated glucose levels.
To date, therapies that have only included the Glucagon-Like Peptide-1 (GLP-1) have demonstrated major success in managing Type 2 DM.
By creating a formulation with BOTH the GIP and GLP incretin hormones, the A1C lowering and weight loss effectiveness has been significantly amplified.
Tirzepatide is a novel synthetic peptide, engineered to provide a once-weekly injectable medication that acts on glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors.
Tirzepatide has been granted FDA approval for treatment of type 2 diabetes based primarily on a series of trials known as SURPASS. The SURPASS 1 trial compared increasing doses to evaluate dose response. The SURPASS 2-5 Trials compared tirzepatide to the GLP-1 semaglutide and to the basal insulins degludec and glargine. In all of the trials, the findings were impressive.
Summary of SURPASS Trials and Results based on Tirzepatide Package Insert.
This once a week injectable is for adults with type 2 diabetes as an adjunct to diet and exercise to improve glycemic control and support weight loss. Tirzepatide is delivered with a single dose prefilled pen.
Starting Dose: 2.5 mg SC every week for 4 weeks initially; THEN increase to 5 mg SC every week. If additional glycemic improvement is needed, increase by 2.5-mg increments after at least 4 weeks at current dose.
Note: The initial 2.5-mg dose is intended for treatment initiation and is not effective for glycemic control
Maximum dose: 15 mg SC qWeek
Common Adverse Side effects: Nausea, diarrhea, abdominal discomfort and injection site hypersensitivity reactions. There is also a black box warning to avoid if family history of medullary thyroid tumor and to report any signs of pancreatitis immediately.
Cost: Tirzepatide is comparably priced to other GLP-1 RAs on the market at $974.33 for four weekly doses, regardless of dose size. Hopefully, insurance companies will recognize the long term benefits of these newer classes of agents, and increase coverage of these beneficial treatment options.
In conclusion: This new medication class substantially lowers blood sugars and body weight, with a once a week injection. Coupled with healthy eating and keeping active, people with diabetes have the opportunity to improve their health and quality of life with this novel medication class.
Author’s note: Beverly Thomassian has no conflict of interest to report and distilled the content of this article from the SURPASS study results and the tirzepatide package insert.

The injectable GLP-1 semaglutide (Ozempic) can now be dosed up to 2.0mg a week. This higher maximum dose provides greater reductions in body weight (6.9kgs vs 6.0kgs) and A1c (2.2 vs 1.9% ) when compared to 1.0 semaglutide dose. There was a comparable safety profile with both doses. However, more people experienced negative gastrointestinal side effects when receiving the higher dose (34% compared to 30.8%).
This is good news for people with type 2 diabetes who would like to benefit from both A1C and weight reduction. Plus, semaglutide lowers the risk of cardiovascular events.
Without insurance coverage, this medication costs about $1000 for a month’s supply. However, since semaglutide (Ozempic) is an established diabetes medication covered by many insurance plans, we are hopeful that people who would benefit from this therapy will have access to this higher dose.
The SUSTAIN FORTE trial lasted for 40-weeks and enrolled 961 patients with type 2 diabetes with an A1C of 8.0-10.0%. All patients in the trial initiated treatment with a 0.25 mg dose of semaglutide that was doubled every 4 weeks until the target dose was achieved.
In addition to reduction in A1C and body weight, the semaglutide 2.0 mg arm of the trial saw a greater proportion of patients achieve an A1C less than 7% (67.6% vs 57.5% [OR, 1.60; 95% CI, 1.21-2.13; P=.001]) or a body weight reduction greater than 5% (59.2% vs 51.3% [OR, 1.41; 95% CI, 1.08-1.84]) than the semaglutide 1.0 mg arm.
We have updated our Diabetes Medication PocketCard with this higher maximum dose or our website, CDCES Coach App, and printed PocketCards.

Read More: What is a CDCES? First awarded in 1986, as Certified Diabetes Educator (CDE) credential and in 2020 with a new name: Certified Diabetes Care and Education Specialist (CDCES) to more accurately reflect the specialty. CDCES has become a standard of excellence for the delivery of quality diabetes education. Those who hold this certification are known to possess comprehensive knowledge of and experience in diabetes prevention, management, and prediabetes. “Becoming a Certified Diabetes Care and Education Specialist (CDCES) is one of the best professional and personal decisions I have ever made.” – Coach Beverly Thomassian, RN, MPH, CDCES, BC-ADM
Read More: 3 Reasons to Become a CDCES “The best part of becoming a CDCES is working with my colleagues and people living with diabetes. As diabetes educators, we hear compelling and beautiful life stories. I am astounded by the barriers they face and inspired by their adaptability, problem-solving skills, and resilience.” Reason 1: CDCES is a widely recognized certification by employers and health care professionals throughout the U.S. This credential demonstrates a specialized and in-depth knowledge in the prevention and treatment of individuals living with pre-diabetes and diabetes. Reason 2: Currently, 10% of people in the U.S. have diabetes and another 35% have pre-diabetes which means 45% of Americans are running around with elevated blood glucose levels. Given this epidemic, there will be plenty of future job opportunities. Reason 3: Having my CDCES along with my nursing degree, has opened many doors of opportunity; from working as an inpatient Diabetes Nurse Specialist in a hospital to working as a Manager of Diabetes Education in the outpatient setting to starting my own consulting company.

Diabetes medications are not just about glucose management anymore
In the past, to determine the right medication for an individual, the primary focus was placed on the glucose-lowering impact. However, with the introduction of the SGLT-2 Inhibitors and GLP-1 RA’s, there has been a tremendous leap forward and expansion of expectations for the co-benefits of diabetes medications.
The SGLT2s and GLP1’s, are both associated with weight loss without the fear of hypoglycemia. They decrease the risk of cardiovascular events and also offer renal protection. In addition, the SGLT-2s are so effective at treating heart failure (HF), that they are now being used for people with HF without diabetes.
Keeping close tabs on UACR and GFR
A big shift in determining the optimal diabetes treatment now includes thoughtful evaluation of Urinary Albumin Creatine Ratio (UACR) and GFR.
In the past, we collected UACR and GFR yearly to monitor kidney function. Now we use the results of these tests to determine not only kidney function but the risk of heart disease and the best therapy for diabetes, kidney health, and hypertension.
Now, more than ever, we are compelled to evaluate urinary labs to determine the albumin to creatinine ratio and keep a close eye on GFR to determine best practices to not only extend lifespan but improve healthspan.
For more info on UACR and GFR, see our blog post, “From Dipsticks to GFR – How to evaluate kidney function“.
Our updated Medication PocketCards reflect these shifts
In this latest version available for download and purchase, we have expanded and clarified the SGLT-2 considerations to reflect the changes in the 2022 ADA Standards of Care. We recognize that SGLT2 Inhibitors may be used as first-line therapy due to their additional benefits, “Along with metformin, SGLT-2s may be considered at first line diabetes therapy, especially for those with heart and kidney failure.” Since this class also slows the progression of chronic kidney disease, we also added, “for renal protection, use SGLT-2 Therapy if eGFR greater than or equal to 25 and UACR greater than or equal to 300.”
Since the GFR cut-offs for this med class are changing frequently, we removed the GFR guidelines for individual SGLT2’s and encourage users to review the package insert for the most recent recommendations.
Over the past twenty years, there has been tremendous expansion in the availability of diabetes medications that not only lower glucose but help decrease the progression of common diabetes co-comorbidities. In this evolving medication landscape, our Medication PocketCards capture the critical and current information you need for your clinical practice and certification exams.
Coach Beverly will highlight the key elements of the latest Medication Guidelines by AACE and ADA. We will explore clinical factors to consider when determining the best strategy to improve glucose management in people with type 2 diabetes and other co-conditions. There will be a special focus on cardiovascular risk reduction and renal protection.

Metformin is one of the most widely dispensed oral diabetes medications for good reason. It works great, lowering A1c 1-2% points, with an added benefit of dropping LDL cholesterol levels. It doesn’t cause hypoglycemia or weight gain and it is incredibly cheap. Many pharmacies offer a 3 month supply of this highly effective glucose-lowering medication for $10 or less, and that’s without insurance. This medication also seems to boost the diversity of the gut microbiota, in particularly increased levels of the very beneficial Akkermansia muciniphila.
However, it does have a few drawbacks. A small group of people on metformin will experience a B12 deficiency. This B12 deficiency may manifest as neuropathic pain or anemia.
Plus, a percentage of people will experience upset stomach, bloating, and diarrhea. People with these complaints will often respond better to the extended-release version (metformin XR), which isn’t any more expensive and it can be taken once a day. See our Mediation PocketCards for more info.
Currently, the ADA Standards have no clear recommendation for checking B12 for those on metformin, but it does note that long-term metformin use is associated with B12 deficiencies and that “measuring B12 levels should be considered for those with type 1 diabetes, peripheral neuropathy or unexplained anemia”.
To add to this, a study published this month in Human Nutrition and Metabolism, found the prevalence of B12 deficiency appears to be about 17% in people on metformin therapy. The highest rates of B12 deficiency were seen in those taking metformin for 2 years. Moreover, vitamin B12 deficiency is influenced by the occurrence and duration of diabetes.
They also measured the intake of vitamin B12 in the daily diet of the study participants. Those with lower vitamin B12 blood levels were also consuming less foods rich in vitamin B12 in their daily meal plan.
The authors of this article suggest that routine monitoring for vitamin B12 serum levels is needed in people with T2DM, particularly when metformin is used for more than 2 years with a dose of over 1000 mg per day. They also recommend further studies are needed to assess the correlation between metformin duration and dose and patients with T2DM and other metabolic syndromes.
B12 replacement therapy
This article, nor the ADA Standards recommend dosing for B12 replacement therapy. However, based on several articles, including this 2005 Cochrane review, high-dose oral replacement (1 mg to 2 mg per day) for B12 deficiency, seems to be as effective as parenteral B12 administration for correcting anemia and neurologic symptoms.
Conclusion – Vitamin B12 deficiency is associated with worsening nerve pain and anemia. Testing B12 levels for those on long-term metformin therapy, especially for those taking more than 1000 mg of metformin a day seems like a reasonable approach. Increasing the intake of foods high in vitamin B12 and providing oral B12 replacement therapy of 1 mg to 2 mg a day, are both helpful interventions to boost B12 levels.
