Metformin and Long Covid: A New Ray of Hope for Diabetic Patients
As the COVID-19 pandemic continues to evolve, researchers are identifying new ways to mitigate its long-term effects.
One such finding is the potential for metformin, a common drug used to treat type 2 diabetes, to reduce the risk of developing long COVID.
This groundbreaking discovery, supported by studies funded by the National Institutes of Health (NIH), suggests that metformin may offer significant protection for diabetic patients.
In this article, we will explore the evidence behind this discovery, the potential mechanisms, and the broader implications of metformin’s use in preventing long COVID.

What is Long COVID?
Long COVID, also known as post-acute sequelae of SARS-CoV-2 (PASC), refers to a range of symptoms that persist for weeks, months, or even years after the initial infection with the COVID-19 virus.
Common symptoms include chronic fatigue, brain fog, chest pain, and shortness of breath. For many, long COVID has severely impacted their quality of life, and researchers have been searching for effective treatments to prevent or reduce its effects.
The Role of Metformin in Diabetes
Metformin is one of the most widely prescribed medications for managing type 2 diabetes. It helps control blood sugar levels by improving the body’s response to insulin and decreasing the amount of glucose produced by the liver.
Due to its safety, affordability, and long-term use in treating diabetes, metformin has gained attention as a potential treatment for other conditions, including COVID-19.
The NIH Study on Metformin and Long COVID
In 2024, a large study funded by the NIH investigated the potential role of metformin in reducing the risk of long COVID in adults with type 2 diabetes.
The study analyzed health records from nearly 38 million patients, comparing those who were taking metformin to those using other diabetes medications.
The results were promising: diabetic patients taking metformin had a 13% to 21% lower risk of developing long COVID or dying from COVID-19 compared to those on other medications.
The findings build on previous research from 2023, which showed that metformin reduced the risk of long COVID by 40% in adults with overweight or obesity, regardless of their diabetes status.
This suggests that metformin may have a broad application in preventing long COVID across different populations.
How Metformin Reduces Long COVID Risk?
While the exact mechanisms behind metformin’s ability to reduce the risk of long COVID are not fully understood, researchers have proposed several potential explanations.
One theory is that metformin has anti-inflammatory properties that may reduce the inflammation triggered by the COVID-19 virus. This is crucial because inflammation plays a significant role in the development of long COVID symptoms.
Additionally, metformin may help decrease the viral load by inhibiting viral replication, preventing the virus from lingering in the body and causing prolonged symptoms.
Metformin has also been found to suppress the formation of disease-related proteins that may contribute to long-term complications from COVID-19.
Broader Implications for Metformin Use
The discovery that metformin could reduce the risk of long COVID has broader implications beyond the diabetes community.
As researchers continue to study its effects, there is potential for metformin to be used as a preventive treatment for long COVID in other high-risk populations, such as individuals with obesity or chronic health conditions.
Moreover, the affordability and accessibility of metformin make it an attractive option for widespread use. Unlike many newer treatments, metformin is widely available and has a well-established safety profile, making it an ideal candidate for broader public health interventions.
However, it is important to note that while metformin shows promise, it is not a cure for long COVID.
It is better to include best supplements to lower blood sugar in your diet.
Further randomized clinical trials are needed to confirm these findings and understand the full scope of metformin’s impact on long COVID across different populations.
Conclusion: Is Metformin a Game-Changer for Long COVID?
The research funded by the NIH provides compelling evidence that metformin could play a significant role in reducing the risk of long COVID in diabetic patients.
The drug’s ability to lower inflammation, reduce viral loads, and prevent the development of long-term complications makes it a promising candidate in the ongoing fight against COVID-19’s lingering effects.
While further research is needed to confirm these results and explore the broader applications of metformin in non-diabetic populations, the findings offer hope for millions of individuals affected by long COVID.
As scientists continue to investigate the potential of metformin, it could emerge as a critical tool in preventing long COVID and improving outcomes for those at risk.
