The Connection Between Urinary Tract Infections and Diabetes – What Floridians with Diabetes Need to Know

Published on: July 14, 2026

As of 2023, about 11% of Florida’s adult population had been diagnosed with diabetes. With more than two million people managing this condition across the state, it is essential to understand the increased risk of urinary tract infections (UTIs) among people with diabetes.

Recurrent UTIs can sometimes be associated with diabetes or poorly controlled blood sugar, but having repeated UTIs does not necessarily mean you have diabetes. Diabetes can make infections more likely, while an active UTI may temporarily make blood sugar more difficult to control.

UTIs can be incredibly uncomfortable, but there are steps you can take to reduce your risk. Keep reading to discover the connection between urinary tract infections and diabetes, whether a UTI can cause high blood sugar, the common symptoms to watch for, and when to seek medical care. The sooner you work to manage these conditions, the easier it may be to protect your health and reduce the risk of complications.

Concerned about recurrent or difficult-to-treat UTIs? Speak with your primary care provider about your symptoms. For specialized infectious disease care in Tampa Bay, call Infectious Disease Associates of Tampa Bay at 813-251-8444.

What Are Urinary Tract Infections (UTIs)?

A urinary tract infection is an infection within the urinary tract system, which includes the organs that produce, collect, and eliminate urine. UTIs usually begin when bacteria enter the urethra, the tube through which urine leaves the body.

Women are generally more susceptible to UTIs, but having diabetes can increase anyone’s risk. Common UTI symptoms include:

• A strong or persistent need to urinate
• Urinating more frequently than usual
• A burning sensation when urinating
• Cloudy, dark, or bloody urine
• Lower abdominal or bladder discomfort
• Back or side pain
• Fever or chills

The most common types of UTIs include cystitis, which affects the bladder; urethritis, which affects the urethra; and pyelonephritis, which is a potentially serious kidney infection.

UTIs begin when bacteria enter the urinary tract. Factors such as certain types of birth control, inadequate hygiene practices, urinary retention, and an impaired immune system may increase the risk. Due to certain risk factors associated with diabetes, people with the condition may experience UTIs more frequently than those without diabetes.

How Diabetes Increases the Risk of UTIs

The connection between diabetes and UTIs can sometimes be overlooked. Several diabetes-related changes may make it more difficult for the body to prevent and fight urinary infections.

High Blood Sugar and Glucose in the Urine

When blood sugar levels remain elevated, glucose may pass into the urine. This is known as glycosuria. The presence of additional glucose in the urinary tract may create conditions that allow bacteria to grow more easily.

Keeping blood sugar within the range recommended by your healthcare provider may help reduce infection risk and support the body’s immune response.

Changes in the Immune System

If you have diabetes, your immune system may be less effective at fighting infections. According to the Centers for Disease Control and Prevention, people with diabetes may experience certain illnesses, including urinary tract infections, more frequently and may take longer to recover.

Diabetic Neuropathy and Urinary Retention

Nerve damage caused by diabetes can affect bladder sensation and control. Some people may not feel when their bladder is full or may have difficulty emptying it completely.

Urine that remains in the bladder can allow bacteria to multiply, contributing to urinary tract infections and recurrent symptoms.

Can Recurrent UTIs Be a Sign of Diabetes?

Recurrent UTIs can sometimes be associated with diabetes, especially when they occur alongside other possible symptoms of high blood sugar. However, recurrent infections alone cannot confirm that someone has diabetes.

The CDC’s list of possible diabetes symptoms includes frequent urinary tract or yeast infections. Other possible symptoms include:

• Increased thirst
• Frequent urination
• Increased hunger
• Unexplained weight loss
• Fatigue
• Blurred vision
• Slow-healing cuts or wounds
• Numbness or tingling in the hands or feet

A person with diabetes who develops a UTI may have a higher risk of recurrence because of glucose in the urine, immune-system changes, poor bladder function, or difficulty fully emptying the bladder.

When someone with diabetes develops a UTI, the infection may become a recurring issue due to these factors. The symptoms can interfere with work, sleep, and everyday activities. Symptoms may also worsen quickly, making timely evaluation and effective treatment especially important.

If you have frequent UTIs and have not been diagnosed with diabetes, talk to your healthcare provider. They can review your symptoms, risk factors, and medical history and determine whether blood glucose testing or another evaluation is appropriate.

Can a UTI Cause High Blood Sugar?

Yes, a UTI may temporarily raise blood sugar, particularly in people who already have diabetes.

When the body is fighting an infection, it may release stress hormones that make insulin less effective and cause the liver to release more glucose. As a result, blood sugar readings may be higher than usual until the infection improves.

Illness can affect people differently. Fever, reduced appetite, vomiting, dehydration, and changes in activity may cause blood sugar to rise or fall. People with diabetes should follow the sick-day plan provided by their diabetes care team and review the CDC’s general guidance for managing diabetes during illness.

Do not stop or adjust insulin, diabetes medication, or antibiotics unless your healthcare provider instructs you to do so. Contact your diabetes care team if your glucose readings remain outside your recommended range.

Symptoms of UTIs in People With Diabetes

If you have diabetes, recognizing UTI symptoms early is essential. The most common symptoms are painful urination, a frequent urge to urinate, and urine that appears cloudy or contains blood.

Other symptoms may include lower abdominal pressure, bladder pain, fever, chills, fatigue, or back and side pain. Symptoms may become more severe or lead to complications if the infection spreads to the kidneys.

Some UTI and high-blood-sugar symptoms can overlap:

Because both conditions may cause frequent urination or fatigue, symptoms alone cannot determine whether you have a UTI, elevated blood sugar, or both. A healthcare provider may recommend urine and blood testing.

Early detection and treatment are critical for avoiding complications related to UTIs or diabetes management. If you develop symptoms, contact a healthcare professional promptly to reduce the risk of the infection worsening or returning.

Diabetes can make infections more complicated. If urinary symptoms are worsening, treatment is not working, or blood sugar is becoming difficult to manage, call IDATB at 813-251-8444 to discuss whether an outpatient infectious disease consultation is appropriate.

Are UTIs Different in People With Type 2 Diabetes?

People with Type 2 diabetes may be more likely to experience recurrent or complicated UTIs, particularly when blood sugar is not well controlled.

High glucose levels, changes in immune function, diabetic nerve damage, and incomplete bladder emptying may all contribute to infection risk. Some people with diabetes may also experience less noticeable symptoms because nerve damage can affect bladder sensation.

For these reasons, people with Type 2 diabetes should not ignore changes in urination, unusual glucose readings, unexplained fatigue, or other possible signs of infection. Early testing can help determine whether symptoms are caused by a UTI, high blood sugar, or another condition.

How Are UTIs Diagnosed?

Healthcare professionals typically diagnose a UTI using your medical history, symptoms, a physical examination, and laboratory testing.

Urinalysis

A urinalysis examines a urine sample for signs of infection, such as white blood cells, bacteria, or blood.

Urine Culture

A urine culture can identify the bacteria causing an infection and help determine which antibiotic may be appropriate. This can be particularly important for people with diabetes, recurrent UTIs, or infections that have not responded to previous treatment.

According to the National Institute of Diabetes and Digestive and Kidney Diseases, additional testing such as urinary tract imaging or cystoscopy may sometimes be considered when bladder infections repeatedly return.

Do not take leftover antibiotics or medication prescribed for someone else. The correct treatment depends on the cause of the infection, your medical history, kidney function, previous treatments, and other individual factors.

Preventing UTIs in People With Diabetes

While it may be concerning to know that diabetes can increase the likelihood of UTIs, there are steps you can take to reduce your risk.

Manage Your Blood Sugar

Blood sugar management is critical for anyone with diabetes. Keeping blood sugar within your recommended range may also reduce UTI risk by limiting excess glucose in the urine and supporting immune function.

Work with your healthcare provider to create a plan for managing your condition, and regularly monitor your blood sugar as recommended, no matter how busy your day becomes.

Stay Appropriately Hydrated

Hydration can help support urinary tract health and regular urination. Drinking enough fluids may help flush bacteria from the urinary tract and prevent urine from remaining stagnant.

Ask your healthcare provider how much fluid is appropriate for you, particularly if you have kidney disease, heart disease, or another condition that requires fluid restriction.

Urinate Regularly and Empty Your Bladder

Avoid holding urine for long periods. Regular urination and fully emptying your bladder each time you use the bathroom may help prevent bacterial buildup and keep your bladder healthier.

If you regularly feel that you cannot completely empty your bladder, discuss this with your healthcare provider. It may be a sign of urinary retention or diabetes-related nerve damage.

Follow Good Hygiene Practices

Good hygiene practices should always be maintained to reduce the chance of infection. Clean the genital area gently during a shower or bath, change underwear regularly, and avoid clothing that is excessively tight or traps sweat and moisture.

Regular medical checkups are also a crucial part of successfully managing diabetes. Talk to your medical provider about UTI testing when you have symptoms and about other infections or health concerns that could cause future complications.

Managing UTIs in People With Diabetes

If you experience UTI symptoms, contact a healthcare professional promptly. Timely evaluation can help you receive the diagnosis and medication you need before the infection becomes more serious.

Bladder infections caused by bacteria are commonly treated with antibiotics. Once diagnosed, carefully monitor your symptoms to ensure they are improving and fully resolve during treatment.

Take antibiotics exactly as prescribed and complete the full course unless your healthcare provider gives you different instructions. Contact your provider if:

• Your symptoms are not improving
• Your symptoms return after treatment
• You experience medication side effects
• Your blood sugar remains unusually high or low
• You develop new or worsening symptoms

In the long term, continue following your diabetes management plan and the preventive steps discussed above to help reduce the risk of recurrent infections.

When to Seek Urgent Medical Care

A bladder infection can sometimes spread to one or both kidneys. According to the NIDDK’s kidney infection guidance, you should seek prompt medical care for symptoms such as:

• Fever and chills
• Pain in your back, side, or groin
• Nausea or vomiting
• Severe or worsening urinary pain
• Confusion
• Rapid breathing or heart rate
• Shortness of breath
• Severe weakness or dehydration

People with diabetes should also follow their healthcare provider’s instructions for unusually high glucose readings, ketones, vomiting, or difficulty keeping fluids down.

Call 911 or seek emergency care for severe symptoms, confusion, difficulty breathing, or other signs of a medical emergency.

Frequently Asked Questions

Can recurrent UTIs be a sign of diabetes?

Recurrent UTIs can sometimes be associated with diabetes or poorly controlled blood sugar, but they do not confirm diabetes on their own. If infections repeatedly return, especially alongside increased thirst, frequent urination, fatigue, or slow-healing wounds, discuss diabetes testing with your healthcare provider.

Does a UTI cause high blood sugar?

A UTI may temporarily raise blood sugar because the body releases stress hormones while fighting an infection. This effect may be more noticeable in people with diabetes. Blood sugar should be monitored according to your healthcare provider’s sick-day instructions.

Can a UTI cause high blood sugar in someone without diabetes?

A significant infection may temporarily raise blood sugar even in someone without diagnosed diabetes. However, repeated or persistently elevated readings require professional evaluation because they may be related to diabetes, another medical condition, medication, or the body’s response to illness.

Why are UTIs more common in people with Type 2 diabetes?

High blood sugar may lead to glucose in the urine, while diabetes-related immune changes can make infections harder to fight. Diabetic nerve damage may also prevent the bladder from emptying completely, giving bacteria more time to grow.

Can high blood sugar feel like a UTI?

High blood sugar and a UTI can both cause frequent urination and fatigue. Burning during urination, urinary urgency, cloudy urine, or lower abdominal pain are more suggestive of a UTI. Testing is often needed because symptoms can overlap.

When should someone with diabetes seek care for a UTI?

Contact a healthcare professional when UTI symptoms appear. Seek urgent care for fever, chills, back or side pain, vomiting, confusion, breathing problems, severe weakness, or glucose levels that remain outside the range established by your diabetes care team.

When should I see an infectious disease specialist for recurrent UTIs?

Specialized evaluation may be appropriate when UTIs repeatedly return, involve resistant bacteria, do not improve with standard treatment, lead to hospitalization, or are complicated by diabetes or another medical condition. Your primary care provider can help determine whether a referral is needed.
