Chronic kidney disease (CKD) is a common complication of diabetes, affecting around 1 in 3 diabetic adults. Both Type 1 and Type 2 diabetes can cause kidney disease, leading to serious health problems.
However, a groundbreaking clinical trial conducted by Novo Nordisk has yielded promising results. The trial suggests that semaglutide, marketed as Ozempic, could potentially reduce the risk of kidney disease-related events in individuals with Type 2 diabetes and CKD.
In this article, you will learn how Ozempic could be a game-changer in slowing down the progression of CKD. We’ll explore the science behind the drug, the results of the clinical trial, and what this means for people living with diabetes and CKD.
How Does Diabetes Lead to Kidney Disease
Diabetes can lead to kidney disease, known as diabetic nephropathy, by damaging the small blood vessels in the kidneys. When someone has diabetes, their body’s high blood sugar levels can harm these vessels, making it hard for the kidneys to clean the blood properly. Over time, this damage prevents the kidneys from doing their job well, leading to a build-up of waste products in the body. If it gets really bad, it can cause the kidneys to fail, which is a serious health issue. Keeping diabetes under control and managing blood pressure can help slow down or prevent this kind of kidney damage.
The symptoms of diabetic nephropathy may not appear in the early stages. However, as the condition progresses to later stages, symptoms can include:
- High blood pressure becomes more difficult to control.
- Swelling in the feet, ankles, hands, or eyes.
- Urine that appears foamy.
- Confusion or difficulty thinking.
- Shortness of breath.
- Loss of appetite.
- Nausea and vomiting.
- Itching.
- Tiredness and weakness.
How Does Ozempic Slow The Progression Of Chronic Kidney Disease?

Ozempic, containing the active ingredient semaglutide, enhances kidney function primarily by stabilizing blood sugar levels in individuals with diabetes, reducing the strain on the kidneys. Elevated blood sugar levels can damage the tiny blood vessels and nephrons in the kidneys, impairing their ability to filter waste effectively.
By improving blood glucose control, Ozempic helps prevent further damage to these vital structures, thus preventing the progression of kidney disease. Additionally, the drug has been shown to aid in weight loss and reduce inflammation, improving kidney health by reducing blood pressure and thereby lessening the kidneys’ workload.
What Does the Research Say?
The FLOW trial, initiated by Novo Nordisk, was a study conducted to evaluate the effectiveness of Ozempic (semaglutide) in slowing down the progression of chronic kidney disease (CKD) in patients with Type 2 diabetes (T2D). The trial was double-blind and placebo-controlled, comparing injectable semaglutide (1.0 mg) with placebo as an adjunct therapy to standard CKD care.
The study involved 3,533 participants with T2D and moderate to severe kidney disease across 28 countries. The trial started in 2019 and was set to conclude in October 2023 but concluded a year ahead of schedule due to the demonstrated effectiveness of the drug.
The FLOW trial showed that participants who were treated with Ozempic experienced a 24% reduction in the risk of progression of kidney disease compared to those who received a placebo. Additionally, the study indicated a decrease in mortality from the kidney—and cardiovascular-related complications among the semaglutide group. However, the precise figures regarding these outcomes are still pending detailed publication.
Are There Any Risks or Side Effects?
Like all medications, Ozempic comes with possible side effects. During the trial, Ozempic was generally safe and well-tolerated, with side effects in line with those observed in previous drug studies. Common side effects associated with GLP-1 receptor agonists like Ozempic include gastrointestinal issues such as nausea, vomiting, diarrhea, abdominal pain, and decreased appetite. These side effects are often mild to moderate in intensity and tend to decrease over time as the body adjusts to the medication.
Could Ozempic And Other Diabetes Drugs Reduce The Need for Dialysis?

Despite the promising results of the FLOW trial, experts and dialysis specialists, including those from major providers like DaVita, caution against assuming these findings will significantly reduce the need for dialysis across the broader CKD patient population.
Specificity of Trial Participants: The FLOW trial participants were a specific subset of the CKD population, primarily those with type 2 diabetes and moderate to severe CKD. The outcomes may not be generalizable to all CKD patients, especially those with different underlying causes of kidney failure.
Long-term Efficacy and Safety: While the FLOW trial provides crucial data on the short to medium-term benefits of Ozempic for CKD progression, the long-term effects, particularly concerning the delay or prevention of dialysis, remain uncertain.
Narrow Subset of CKD Patients: Dr. Jeff Giullian, the chief medical officer for DaVita, noted that the trial’s inclusion criteria might limit its findings to a small portion of the CKD population. Less than 10% of all CKD patients meet these criteria, suggesting that the trial’s results may only apply to some patients.

Final Thoughts
Ozempic has potential benefits for individuals with diabetes at risk of chronic kidney disease (CKD). It helps control blood sugar levels and can lower the risk of kidney damage. Studies show that Ozempic can slow the progression of CKD, which might reduce the need for dialysis in the future. Despite its benefits, users should be aware of possible side effects and keep a close eye on their kidney function. While more research is needed to understand its long-term impact fully, Ozempic offers a promising option for managing diabetes and protecting kidney health.
