Is Watermelon Good For UTIs? The Pros and Cons

Urinary tract infections (UTIs) are extremely common, affecting millions of people every year. The infection occurs when bacteria enter the urinary tract, usually through the urethra, and begin to multiply in the bladder. Common symptoms of a UTI include a persistent urge to urinate, burning or pain during urination, cloudy or bloody urine, and pelvic discomfort or pain.

For many people suffering from a UTI, the first question that comes to mind is what they can and cannot eat to help ease symptoms and promote healing. Watermelon in particular is a food that many wonder about when it comes to UTIs. Can eating watermelon help or hurt if you have a urinary tract infection? 

How Watermelon Impacts UTIs

Watermelon is made up of 92% water, giving it natural diuretic properties. Many believe that increasing urine output helps flush bacteria from the bladder more quickly, thus easing UTI discomfort. Watermelon also contains citrulline, an amino acid that may help relax blood vessels and in turn take pressure off the bladder. This relaxing effect could further diminish UTI symptoms.

Watermelon is rich in vitamin C, an antioxidant that helps strengthen the immune system and ward off infection. Vitamin C makes the urine more acidic, which creates an environment that is less hospitable to the bacteria causing the UTI.

However, watermelon is also naturally high in sugar. Eating too much of the fruit could potentially feed bacteria in the urinary tract rather than flush it out, allowing the infection to worsen .

Potential Benefits of Watermelon for UTI

1. Hydration: A Key Factor

One of the primary concerns when dealing with UTIs is hydration. Staying well-hydrated is crucial to flushing out bacteria and promoting urinary health. As watermelon is mostly water, it can undoubtedly contribute to your daily fluid intake and support urinary function. The high water content in watermelon ensures that your urine remains diluted, making it less likely for bacteria to thrive and cause infections.

2. Rich in Antioxidants

As mentioned earlier, watermelon contains powerful antioxidants like lycopene, which play a vital role in combating free radicals in the body. These antioxidants have been linked to potential anti-inflammatory effects and might help in reducing the risk of certain infections, including UTIs.

3. Natural Source of Vitamins and Minerals

Watermelon is a natural source of essential vitamins and minerals that can boost overall health. Vitamin C, for instance, is known to strengthen the immune system, making it better equipped to fight off infections. While watermelon can’t single-handedly treat a UTI, incorporating it into your diet might be a beneficial step in supporting your body’s defenses.

Here are some of the top ways that watermelon may help ease UTI discomfort and promote healing:

  • Encourages urination and flushing out of bacteria
  • Provides citrulline to relax bladder muscles
  • Boosts vitamin C to support immune function
  • Has mild diuretic effect to reduce bladder pressure
  • Contributes antioxidants to fight inflammation
  • Low in calories for those avoiding heavy foods

Eating watermelon in moderation may amplify urine production, support the immune system, reduce bladder pressure, and decrease inflammation related to the infection. These effects can potentially quicken recovery time.

Potential Risks of Eating Watermelon with UTI

Despite the potential benefits, there are also some possible downsides of eating watermelon with a urinary tract infection:

  • High sugar content could worsen infection
  • May irritate bladder due to acidity
  • Can act as a diuretic leading to dehydration
  • Natural chemicals may interact with medications
  • Could cause gastrointestinal issues like diarrhea

Consuming large amounts of watermelon or drinking juice made from the fruit could feed UTI-causing bacteria due to the high sugar content. The acids in watermelon could also irritate the inflamed bladder.

Frequent urination after eating can lead to dehydration, while chemicals like citrulline may interact with antibiotics or other UTI medications. Some people may experience loose stools after consuming substantial watermelon as well.

Tips for Safely Eating Watermelon with a UTI

If you want to incorporate watermelon into your diet while dealing with a urinary tract infection, keep the following tips in mind:

  • Stick to a small serving size of 1 cup or less
  • Avoid drinking watermelon juice, which has higher sugar
  • Be sure to stay well hydrated by drinking extra fluids
  • Monitor symptoms and stop eating it if you see a negative effect

Consuming watermelon in moderation, about 1 cup diced or less per day, provides benefits without going overboard on sugar. Focus on eating the fruit rather than juicing it. Drink plenty of extra fluids like water or herbal tea to stay hydrated.

Like most aspects of health, moderation is key when considering whether or not to eat watermelon with a UTI. For most people, enjoying a small serving can provide benefits like flushing out bacteria, relaxing the bladder, and supporting the immune system during infection.

However, those with sensitive bladders or who experience side effects may want to avoid it. Pay attention to your own symptoms, fluid intake, and lifestyle habits as well when nursing yourself back to health. With proper care, your UTI should clear within a few days’ time.


Watermelon can be a healthy part of your diet when recovering from a UTI, as long as intake is moderate. While it has some benefits that may ease symptoms, such as lowering bladder pressure and providing antioxidants, eating too much could potentially worsen the infection due to its high sugar content.

Enjoy small portions along with other positive lifestyle changes to support healing. With your doctor’s guidance, watermelon can be a refreshing complement to UTI treatment and speed your recovery. Most importantly, listen to your own body, stay hydrated, and rest as much as possible.
