Why do people use baking soda for UTIs?
Urinary tract infections often come on suddenly and can feel intense. Burning, pressure, and frequent bathroom trips can make it hard to sleep, focus, or get through the day. That constant urge is a big reason people search online for quick solutions they can try at home.
Baking soda (sodium bicarbonate) is commonly suggested because it’s inexpensive, easy to find, and often labeled online as a “natural” remedy. The idea behind it is that baking soda can make urine less acidic. Since acidic urine can sometimes make that burning sensation feel worse, some people believe that changing urine acidity will reduce symptoms or even stop the infection.
What baking soda does in the body
Baking soda is a base, meaning it can neutralize acid. When someone drinks baking soda mixed with water, it can temporarily make the urine less acidic. In short-term research, people who took oral baking soda saw their urine pH shift from acidic to more neutral or alkaline.
This is where the idea comes from that baking soda might help with a UTI. For some people, less acidic urine can briefly reduce the stinging or burning feeling when they pee. If you’re already uncomfortable, even a small change can feel noticeable.
But this effect is only temporary, and it’s important to understand what baking soda doesn’t do. It doesn’t kill bacteria or fungi, nor does it remove them from the urinary tract. And it doesn’t treat the infection itself. UTIs happen because pathogens are growing where they shouldn’t be, not because urine is “too acidic.”
So while baking soda might slightly change how urine feels for a short time, it doesn’t address the real cause of a UTI or help your body clear the infection.
Why baking soda for UTIs became a popular hack
There’s no shortage of health advice online, and unfortunately, not all of it is accurate. Baking soda is often shared as a simple, “natural” solution for UTIs that sounds almost too good to be true.
On social media and home-remedy blogs, baking soda is sometimes framed as a hidden trick or an overlooked cure. You’ll often see claims that a teaspoon of baking soda in water can cure a UTI overnight, flush bacteria out of the bladder, or work just as well as antibiotics — without needing a doctor.
These claims are misleading because they oversimplify what a UTI actually is. A UTI isn’t just irritation caused by acidic urine. It’s an infection caused by bacteria or fungi. Changing urine pH doesn’t remove those germs, even if symptoms briefly feel different.
When advice like this spreads online, it can make baking soda seem harmless or effective, when in reality it may delay proper care and allow an infection to get worse.
Is baking soda good for UTIs? What the evidence says
The short answer is no. There is little to no solid medical evidence showing that drinking baking soda treats UTIs or cures the underlying infection.
Antibiotics are the standard of care because they target the organisms causing the infection. Studies that look at urine alkalization don’t show that this approach treats UTIs or prevents them from coming back.
While baking soda may offer temporary symptom relief for some people, relying on it instead of proper testing and treatment can allow the infection to get worse.
Why baking soda isn’t a recommended UTI treatment
Medical guidelines don’t include baking soda or other urine-alkalizing remedies as treatments for UTIs, and there’s a good reason for that. UTIs are infections caused by bacteria or fungi, and changing the acidity of urine doesn’t remove or kill those germs.
While baking soda can change urine pH, it doesn’t treat the underlying infection. Studies haven’t shown that urine alkalization improves recovery, prevents complications, or stops UTIs from coming back. Because of this lack of proven benefit — and the potential risks — healthcare professionals don’t recommend baking soda as a UTI treatment.
Another reason it’s not recommended is safety. Baking soda contains a large amount of sodium, and taking it regularly or in larger amounts can throw off the body’s balance. Medical treatments for UTIs are designed to clear the infection safely and effectively, while baking soda simply doesn’t meet that standard.
Can baking soda mask UTI symptoms or delay care?
Yes, it can. For some people, baking soda may briefly reduce the burning sensation when they pee or slightly ease urgency. While that can feel like a win in the moment, it can also create a false sense that the infection is improving.
When symptoms seem better, people may put off urine testing or a visit with a healthcare provider. During that time, the bacteria or fungi causing the UTI can continue to grow. Delayed care increases the risk of complications, including infections that spread to the kidneys, symptoms that last longer than necessary, or UTIs that keep coming back.
Risks and side effects of using baking soda for a UTI
Drinking baking soda isn’t harmless, especially when used repeatedly or in larger amounts.
Short-term side effects and overuse
Consuming baking soda can cause:
- Nausea
- Stomach pain
- Bloating
- Muscle twitching
- Changes in the body’s electrolyte balance.
In more severe cases, it can lead to a condition where the body becomes too alkaline, which can affect the heart, muscles, and nervous system.
Who is at higher risk of complications
Some people are more vulnerable to the potential harms of drinking baking soda. Individuals with kidney disease, heart conditions, or high blood pressure are at higher risk because their bodies are less able to handle extra sodium. Baking soda contains a large amount of sodium, and consuming it can lead to fluid retention, swelling, and spikes in blood pressure.
People on sodium-restricted diets or certain medications that affect kidney or heart function should be especially cautious, as even small amounts of baking soda can upset the body’s balance. Using baking soda during pregnancy also carries risks, since excess sodium and changes in the body’s chemical balance can affect both the parent and baby.
While baking soda might seem like a harmless home remedy, these groups face a higher chance of serious complications, making it especially important to avoid using it as a UTI treatment and instead rely on proven, safe medical care.
Evidence-based ways to treat UTIs instead of baking soda
UTIs are most safely treated by confirming what’s causing symptoms and using proven treatments.
How UTIs are diagnosed and treated
If you suspect you have a UTI, healthcare providers usually start with a urine test to see if bacteria or fungi are present. Based on these results (or sometimes on typical symptoms alone), they prescribe antibiotics that are likely to target the infection. This approach works for many, but standard urine cultures can miss a significant number of infections, and sometimes the prescribed antibiotic may not be the most effective choice.
Evvy’s UTI+ Test offers a modern, at-home alternative. Using PCR technology, it can detect multiple UTI-causing bacteria and fungi that standard cultures might miss, as well as key antibiotic resistance genes. This means it can identify the presence of antibiotic-resistant bacteria and help your healthcare provider select a treatment that’s more likely to work the first time. For people dealing with recurring UTIs or unclear symptoms, this targeted information can reduce guesswork and shorten the path to relief.
While antibiotics are necessary to clear the infection, other measures can help you feel more comfortable as treatment takes effect, such as drinking plenty of water and taking pain relievers.
