Impact of Ozempic & Similar GLP-1 Drugs on Gut Health: Insights from NHN Provider Donna Monthei, RD, LD of EverVital Nutrition

weight loss

In the realm of managing Type 2 diabetes and promoting cardiovascular health, GLP-1 receptor agonists like Ozempic, Semiglutide and others have emerged not only as effective treatments but also as potential aids in weight loss. These drugs, originally designed to regulate blood sugar levels, have garnered attention for their multifaceted benefits, but they also warrant careful consideration, particularly regarding their effects on gut health.

Understanding GLP-1 Drugs

GLP-1 drugs such as Ozempic are renowned for their dual action of controlling blood sugar levels and reducing the risk of major cardiovascular events like heart attacks and strokes. Developed primarily for patients with Type 2 diabetes, they work by mimicking the effects of a natural hormone called glucagon-like peptide-1 (GLP-1), which stimulates insulin secretion and inhibits glucagon release after meals, thus lowering blood sugar levels.

Beyond Diabetes: Weight Loss and Cardiovascular Benefits

One of the significant off-label benefits of GLP-1 receptor agonists is their role in weight management. Donna Monthei, RD, LD of EverVital Nutrition, underscores that these medications can aid weight loss, particularly for individuals with over 30 pounds to lose to reach their optimal weight when paired with lifestyle changes such as healthy diet, exercise and stress reduction. This effect can be pivotal not only for aesthetic reasons but also for overall health, as maintaining a healthy weight is crucial in managing diabetes and reducing cardiovascular risks.

Considerations for Gut Health

While the benefits are clear, there are important considerations regarding gut health. Long-term use of GLP-1 drugs, extending beyond six months, has been associated with potential changes in the intestines. Donna Monthei cautions that prolonged use can lead to lengthening of intestinal villi and increased surface area of the small intestine, potentially causing issues like malabsorption, obstructions and overgrowth conditions such as SIBO.

Side Effects and Long-Term Concerns

Like any medication, GLP-1 receptor agonists have side effects that users should be aware of, such as nausea, vomiting, constipation, loss of appetite, and potential impacts on gut motility. Moreover, long-term effects, especially concerning weight loss sustainability and overall health beyond blood sugar control, are areas that require further study.

The Role of Natural Alternatives

Donna Monthei advocates for a holistic approach to weight management and overall health. She emphasizes that while GLP-1 drugs can kickstart weight loss, there are natural alternatives that focus on addressing underlying issues such as gut health and hormone imbalances. As a registered dietitian specializing in holistic nutrition, Donna offers personalized guidance to regulate blood sugar, optimize diet and exercise, and maintain a healthy gut biome.


Guidance and Support

For individuals considering GLP-1 drugs or seeking alternatives, Donna Monthei recommends comprehensive gut biome testing before and after the course of medication. This proactive approach helps in understanding and mitigating any potential impacts on gut health.


In conclusion, GLP-1 receptor agonists like Ozempic offer significant benefits beyond their primary role in managing Type 2 diabetes, including weight loss and cardiovascular risk reduction. However, users should remain vigilant about potential effects on gut health and consider holistic approaches, such as those advocated by Donna Monthei, to achieve sustainable health improvements.
