The Hidden Risks of Combining SGLT2 Inhibitors with a Keto Diet
Recent cases have brought to light an unexpected danger when patients using sodium-glucose cotransporter-2 (SGLT2) inhibitors adopt a keto diet. Understanding and awareness of this risk are paramount as the prevalence of SGLT2 inhibitors and ketogenic diets continue to rise.
The Synergistic Threat of SGLT2 Inhibitors and Keto Diet
SGLT2 inhibitors, commonly prescribed for managing type 2 diabetes, work by preventing the kidneys from reabsorbing glucose back into the blood. While they’re beneficial for many, recent FDA warnings have underscored the potential risks of acute kidney injury, urinary tract infections, and euglycemic diabetic ketoacidosis (DKA).
What may seem less intuitive is the synergy between SGLT2 inhibitors and ketogenic diets in precipitating DKA. While the FDA warnings on euglycemic DKA emphasize discontinuing these inhibitors before surgery, they don’t specifically mention ketogenic diets. Yet, the combination of these drugs and a high-fat, low-carb diet can thrust the body into ketoacidosis, a condition often underestimated by healthcare professionals.
Breaking Down Communication Barriers in Healthcare
The American healthcare system often operates in silos, complicating the provision of holistic care. In pharmacy schools, the focus is typically on prominent warnings, and less on nuances like avoiding strictly ketogenic diets while on empagliflozin.
Consequently, dietitians may not screen medication lists specifically for SGLT2 inhibitors when advising on a keto diet. Additionally, clinicians, constrained by the hustle of short consultations, may overlook tailored dietary guidance, assuming these medications are low-risk.
Real-World Cases: A Reminder of the Potential Risks
In recent months, three patients hospitalized with euglycemic DKA were initiated on keto diets while on long-term SGLT2 inhibitor therapy. These cases underscore the potential danger, despite the patients having tolerated the medication without issue for years.
Should We Advise Against Keto Diets With SGLT2 Inhibitors?
While it remains unclear if clinicians routinely discuss patients’ dietary habits, experiences in hospitals suggest that patients often learn about the keto diet independently, through search engines or other unvetted sources. This lack of communication can lead to unexpected complications.
Given these incidents, it’s prudent to consider advising patients against starting a keto diet when on SGLT2 inhibitors. Reporting these cases to the FDA through the MedWatch website could also help highlight this safety concern nationwide.
Looking Forward: Education and Policy Changes
In response to these challenges, healthcare education and policy may need to evolve. Integrating comprehensive discussions of diet and medication interactions in both pharmacy and medical training could help mitigate risks.
Moreover, leveraging technology to incorporate dietary risk assessments in electronic health records could enhance patient safety. For patients, increasing awareness through reliable channels is vital to prevent unwarranted ICU admissions.
FAQ Section
What is euglycemic DKA, and why is it a concern with SGLT2 inhibitors?
DKA is a serious condition characterized by high ketones and low blood pH levels, but often without the typical high blood sugar levels. SGLT2 inhibitors increase the risk of DKA even when blood glucose is normal, known as euglycemic DKA.
Should patients avoid keto diets entirely if taking SGLT2 inhibitors?
While not officially mandated, current evidence suggests that avoiding ketogenic diets while on SGLT2 inhibitors could be a prudent measure to prevent DKA.
How can patients and healthcare providers improve communication about dietary habits?
Patients should proactively discuss their diets with healthcare providers, who in turn should routinely inquire about diet changes or new diet plans during consultations, especially when prescribing SGLT2 inhibitors.
