Foods To Avoid When Treating a Urinary Tract Infection (UTI)

Your diet plays an important role in your health, including preventing disease, illness, and infections. 

Urinary tract infections (UTI) cause over 8 million visits to a healthcare provider’s office annually. 

About 10 in 25 women and 3 in 25 men will experience a UTI in their lifetime.

If you’ve had a UTI, you know how uncomfortable they can be. 

If you haven’t had one yet, you probably want to keep it that way. 

How can your diet influence your UTI risk? We’ll cover that and more in this article.

Keep reading to learn which foods you should avoid, and what foods to include in a UTI diet.

What is a Urinary Tract Infection (UTI)?

A urinary tract infection (UTI) occurs when bacteria enter your urethra (a tube that carries urine from your bladder out of your body) and cause an infection in your urinary tract. Bacteria cause most UTIs, but rarely they can result from a fungus. UTIs are also called bladder infections.

UTIs can impact both men and women but are more prevalent in women. About 50% of women are likely to have a UTI at some point in their lifetime. One of the main reasons women are more likely to get a UTI is because their urethra is shorter than a man’s, which means bacteria don’t have to travel as far to reach the bladder and urinary tract system.

Urinary tract infections are especially problematic during pregnancy and can lead to preterm delivery. They are also more common in menopausal women because a drop in estrogen can trigger UTIs.

If a UTI goes untreated, it can spread to your kidneys and cause a kidney infection, which is why UTI prevention and prompt treatment are so important.

Can your diet prevent or treat a UTI?

Like many health conditions, your diet can greatly affect UTI prevention and treatment. While you might not be able to completely prevent a UTI through diet alone, you shouldn’t overlook the importance of your diet when it comes to UTI risk.

Certain foods can irritate your bladder lining, which can worsen the uncomfortable symptoms of a UTI. Other foods may help prevent UTIs by fighting off bacteria that cause infections. 

Some UTIs can be treated at home (resting, drinking plenty of fluids, eating a healthy diet, etc.), but some will require antibiotics. If you’re still experiencing symptoms of a UTI after several days, you should seek medical attention to see if you need antibiotics. 

Untreated UTIs can lead to kidney infections and more serious issues, so it’s important not to delay medical treatment if necessary. 

Foods to avoid with a UTI

1) Acidic foods

While some acidic foods may help prevent UTIs due to their vitamin C content, you might want to avoid them if you have an active UTI. Acidic foods can irritate the lining of your bladder, especially if it’s already irritated from an active infection.

Some examples of acidic foods include:

  • Citrus fruits
  • Tomatoes
  • Blueberries
  • Plums
  • Peaches

2) Spicy foods

Like acidic foods, eating spicy foods may irritate your bladder lining and intensify discomfort. Avoid eating spicy peppers like jalapenos, as well as black and cayenne pepper.

Eating spicy foods is fine if you’re not currently experiencing a UTI. Spicy foods may help with weight loss, combat inflammation, and improve your longevity, so there’s no need to be afraid of them outside of an active urinary tract infection.

3) Caffeine

Caffeine is a diuretic, which means it makes you urinate more. You should avoid caffeine during a UTI because it might increase the prevalence of symptoms such as burning during urination.

Caffeine may also worsen dehydration, which can exacerbate symptoms like burning while urinating. 

4) Sugary foods and drinks

While sugar doesn’t necessarily cause urinary tract infections, it can feed the bacteria that are present during an active infection. While there isn’t significant research on the topic, it’s never a bad idea to cut back on added sugar.

If you have an active UTI, avoid drinking sugary drinks and foods with added sugar like cookies and desserts and processed foods with added sugar.

5) Alcohol

Drinking alcohol doesn’t increase your risk of a UTI, but it can further irritate your bladder during an active infection. Similar to caffeine, alcohol causes you to urinate more, which may increase the intensity and frequency of UTI symptoms.

For an active UTI, avoid acidic and spicy foods and added sugars, caffeine, and alcohol. To help prevent UTIs, some things that might help when it comes to your diet include drinking berry juices, eating probiotics, getting enough vitamin C, and staying hydrated.
