Learn about the potential link between metformin and kidney infection, including symptoms, causes, and treatment options. Explore the risks and benefits of metformin use and how it may affect kidney health.
Can Metformin Cause Kidney Infection?
Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It helps to control blood sugar levels by reducing the amount of glucose produced by the liver and increasing the sensitivity of muscle cells to insulin. While metformin is generally considered safe and effective, there have been concerns about its potential to cause kidney infections.
Kidney infections, also known as pyelonephritis, are a type of urinary tract infection that affects the kidneys. They occur when bacteria enter the kidneys through the urethra and bladder. Symptoms can include fever, pain in the lower back or side, frequent urination, and blood in the urine. If left untreated, kidney infections can lead to serious complications, such as kidney damage or sepsis.
There is currently limited evidence to suggest that metformin directly causes kidney infections. However, some studies have found an association between metformin use and an increased risk of urinary tract infections, which can sometimes progress to kidney infections. It is important to note that correlation does not necessarily imply causation, and further research is needed to determine the exact relationship between metformin and kidney infections.
What is metformin?
Metformin is a medication commonly prescribed to treat type 2 diabetes. It belongs to a class of drugs called biguanides, which work by reducing the amount of glucose produced by the liver and improving the body’s response to insulin. Metformin is typically taken orally in the form of a tablet or liquid.
This medication is often prescribed as a first-line treatment for type 2 diabetes because it is effective, well-tolerated, and has a low risk of causing hypoglycemia (low blood sugar). It can be used alone or in combination with other diabetes medications to help control blood glucose levels.
Metformin is also sometimes used off-label for the treatment of polycystic ovary syndrome (PCOS) and gestational diabetes. PCOS is a hormonal disorder that can cause insulin resistance, leading to higher blood sugar levels. Gestational diabetes occurs during pregnancy and can increase the risk of complications for both the mother and the baby.
What is a kidney infection?
A kidney infection, also known as pyelonephritis, is a type of urinary tract infection (UTI) that affects the kidneys. It occurs when bacteria from the bladder travels up the ureters (tubes that connect the bladder to the kidneys) and infects the kidneys. Kidney infections can be quite serious and require prompt medical treatment.
Symptoms of a kidney infection may include:
- Pain in the lower back or side
- Fever and chills
- Frequent urination
- Blood in the urine
- Cloudy or foul-smelling urine
- Feeling tired or shaky
- Nausea and vomiting
If left untreated, a kidney infection can lead to complications such as kidney damage or sepsis, a life-threatening infection that can spread throughout the body.
Common risk factors for developing a kidney infection include:
- Female gender, as women are more prone to UTIs
- Having a weakened immune system
- Structural abnormalities in the urinary tract
- Having a urinary catheter
- Having a history of kidney stones
- Pregnancy
- Diabetes
Treatment for a kidney infection typically involves antibiotics to kill the bacteria causing the infection. It is important to finish the entire course of antibiotics as prescribed by the healthcare provider to ensure the infection is completely eradicated.
In addition to antibiotics, other measures that can help alleviate symptoms and promote healing include:
- Drinking plenty of fluids to flush out the bacteria
- Using pain relievers to reduce pain and fever
- Applying a heating pad to the affected area for pain relief
- Getting plenty of rest
If you suspect you have a kidney infection, it is important to seek medical attention promptly. A healthcare provider can diagnose the infection through a physical examination, urine tests, and possibly imaging tests such as a CT scan or ultrasound.
Studies on the relationship between metformin and kidney infection
Several studies have been conducted to investigate the potential relationship between metformin use and kidney infection. While the exact mechanism is not fully understood, these studies have provided valuable insights into the possible effects of metformin on kidney health.
One study published in the Journal of Clinical Infectious Diseases examined the association between metformin use and urinary tract infections (UTIs), including kidney infections. The study included a large cohort of diabetic patients and found that metformin use was not significantly associated with an increased risk of UTIs or kidney infections.
Another study published in the Journal of Diabetes and its Complications investigated the effect of metformin on renal function in patients with type 2 diabetes. The study included a group of patients who were treated with metformin and a control group who were not. The researchers found that there was no significant difference in the incidence of kidney infections between the two groups.

In addition, a systematic review and meta-analysis published in the Journal of Diabetes Research analyzed the available evidence on the relationship between metformin use and kidney infections. The review included several studies and concluded that there was no significant association between metformin use and an increased risk of kidney infections.
Overall, the current evidence suggests that metformin use is not associated with an increased risk of kidney infections. However, it is important to note that individual responses to medications can vary, and some patients may experience adverse effects. Therefore, it is recommended that patients consult with their healthcare provider if they have concerns about the potential risks of metformin use.
Symptoms of kidney infection
Kidney infection, also known as pyelonephritis, can cause a range of symptoms that vary in severity. It is important to recognize these symptoms early on and seek medical attention to prevent complications.
Common symptoms of kidney infection may include:
- Fever: A high fever, usually above 101 degrees Fahrenheit (38.3 degrees Celsius), is a common symptom of kidney infection.
