Semaglutide and Ozempic-like drugs may improve kidney disease outcomes
Semaglutide, a medication widely recognised under the brand names Ozempic and Wegovy for weight loss, is showing significant potential in treating chronic kidney disease. A new analysis reveals that patients with type 2 diabetes and chronic kidney disease who received weekly doses of the drug experienced improved survival rates and kidney function.
Protective Effects on Kidney Function
The findings indicate that the benefits of semaglutide extend to high-risk patients, including those with a history of heart failure, strokes, or heart attacks. Professor Katherine Tuttle of the University of Washington described the medication as a “highly kidney protective therapy.”
According to Professor Tuttle, maintaining kidney function to avoid the necessity of dialysis is just as critical as reducing the risks of major cardiovascular events. Patients with high heart disease risk may be more likely to remain alive and keep their kidney function when treated with semaglutide.
The Connection Between Obesity and Organ Health
The effectiveness of the drug stems from its classification as a GLP-1 receptor agonist. These medications mimic the glucagon-like peptide 1 (GLP-1) hormone, which helps manage blood sugar levels and slows digestion, leading to increased feelings of fullness.

Dr. James Tang, a kidney specialist and transplant physician at St Vincent’s Hospital, notes that obesity, type 2 diabetes, heart disease, and chronic kidney disease are all interconnected. By easing the impact of obesity and diabetes, the drug may create a positive “flow on effect” for the kidneys.
Clinical Context and Study Limitations
The analysis utilized data from the FLOW trial, which was funded by Novo Nordisk, the manufacturer of Ozempic and Wegovy. Natalie Raffoul, a registered pharmacist and senior manager for the Heart Foundation, stated that such industry sponsorship is standard for most major clinical trials.
Professor Tuttle acknowledged certain limitations in the study, noting that the participants were predominantly white, male, and older. The researcher expressed a need for more women and greater racial and ethnic diversity in future studies, as well as a longer duration to provide more statistical power for secondary outcomes.
Future Implications for Patient Care
The World Health Organization has recently recommended Ozempic-style medications as long-term treatments for obesity. Similarly, the Heart Foundation suggests considering semaglutide for weight loss in people with established cardiovascular disease to reduce future risks.

Researchers are now looking to determine if the heart health improvements are driven primarily by weight loss or if the drug possesses independent “anti-inflammatory effects.” Future evidence could clarify whether the medication’s benefits are a result of weight management or a direct pharmacological action on the cardiovascular system.
Medical professionals emphasize that these drugs require a prescription and carry potential risks and side effects. Treatment is generally recommended only when the clinical benefits outweigh the associated risks.
Frequently Asked Questions
What is chronic kidney disease?
It is a general term for kidney conditions that affect the removal of waste from the blood for a period of three months or longer.
How does semaglutide help with weight loss?
As a GLP-1 receptor agonist, it mimics a natural hormone that slows digestion and helps people feel full longer, often reducing incessant thoughts about food.
Who can benefit from semaglutide according to the FLOW trial analysis?
People with type 2 diabetes and chronic kidney disease, including those with a history of heart failure, strokes, or heart attacks, showed improved survival rates and kidney function.
How do you think the integration of weight-loss medications into kidney care will change long-term treatment strategies?
