Urinary tract infections (UTIs) are no fun. These infections happen when bacteria makes its way into your urinary tract, and they’re pretty common, especially in women. Some research suggests that up to 40% of women in the US will experience a UTI in their lifetime.
Many people use lubricants to make sex more comfortable. In fact, one study says that around 62% of women in the United States have used lube during sex.
But can lube cause UTIs? That’s the question we’re tackling in this article. We’ll explore the possible links between lubricants and UTIs, break down the risks, and offer some tips on choosing a lube that’s less likely to cause problems.
Understanding the link between lubricants and UTIs
So, can lube really cause a UTI? Here’s what you need to know.
How sexual activity plays a role
Any kind of sexual activity can increase your risk of getting a UTI because bacteria can be transferred into the urethra during sex. Bacteria can easily enter the urinary tract, and if they multiply, you may find yourself dealing with a UTI.
Vaginal dryness can make this situation even worse. When there’s not enough lubrication, intercourse can cause friction, which can sometimes lead to small tears or breaks in the skin. These tiny injuries can make you more prone to infection.
The role of vaginal microbiome and pH
It’s super important to have a healthy vaginal microbiome to keep UTIs at bay. The vagina naturally contains good bacteria, like Lactobacillus, that help maintain a healthy environment and keep harmful bacteria from taking over.
Lubricants can sometimes mess with the natural pH balance of the vagina. The normal vaginal pH range is 3.8 to 4.5. When lubricants disrupt this balance, it can become easier for bad bacteria to thrive, increasing the chances of a UTI.
Lubricant ingredients to watch out for
Some ingredients in lubricants can irritate the vagina and disrupt its natural balance of good bacteria, which, in turn, can make you more prone to UTIs. Here’s what to look for on the label:
- Spermicides (Nonoxynol-9). Studies have shown that using condoms with spermicide may increase your risk of getting a UTI.
- Flavors and sugars. Flavored or sweetened lubes can change the mix of bacteria in your vagina and increase the likelihood of infection.
- Preservatives (like parabens). Preservatives can irritate your vagina and throw off the natural balance of vaginal bacteria.
- Glycerin and propylene glycol. These ingredients may contribute to UTIs, especially if the glycerol content is higher than 9.9% or the propylene content is higher than 8.3%.
Osmolality and why it matters
Osmolality refers to the concentration of particles in a solution. Normal vaginal fluid has an osmolality of 260–290 mOsm/kg. Lubricants with high osmolality can pull moisture from vaginal tissues, causing damage and increasing your risk of a UTI.
According to some studies, some lubes have an osmolality as high as 6000 mOsm/kg — way too high for vaginal health.
Choosing the right lube: A guide to safer options
If you’re prone to UTIs, the type of lube you use matters. Here’s a rundown of the different types of lube and how they might affect your urinary health:
Water-based lubricants
Water-based lubes are usually considered the safest choice because they’re least likely to disrupt the natural pH and flora of your vagina. Plus, water-based lube is easy to wipe away after sex.
If you go with a water-based lube, be sure to read the ingredient list and choose one that doesn’t have a lot of additives that could irritate your sensitive tissues.
Silicone-based lubricants
Silicone-based lubes last longer than water-based products, so that’s a plus. But even though they’re generally considered safe, you should still check the label for ingredients that could cause irritation.
Oil-based lubricants and their limitations
Oil-based lubes aren’t a good choice if you’re using condoms because they can break down the latex. They’re also harder to clean off your body, and that could lead to bacterial growth.
pH-balanced and natural lubricants
Choosing a lube with a balanced pH is a good way to support the health of your vagina. And natural lubes usually have fewer synthetic ingredients, so you’re less likely to have a reaction.
Beyond Lube: Additional Tips for UTI Prevention
There are several steps you can take to help prevent UTIs, including the following.
Hygiene Practices
- Pee after sex. Urinating after sexual activity helps flush bacteria out of your urethra before it has a chance to cause an infection.
- Wipe front to back. After you pee or poop, always wipe from front to back. This prevents bacteria from your anus from getting into your urinary tract.
- Avoid douching and harsh soaps. These products can mess with the balance of bacteria in your vagina and make you more prone to UTIs.
Hydration and Diet
- Stay hydrated. Drinking plenty of water helps flush bacteria out of your urinary tract. Aim for around 11.5 cups of water per day.
- Modify your diet. Some people find that avoiding acidic, alcoholic, caffeinated, fatty, and spicy foods and drinks can help prevent UTIs.
Other preventative measures
- Wear cotton underwear. Cotton is a breathable fabric that can help keep your vaginal area dry and prevent bacteria from growing.
- Consider probiotics. Probiotics can help maintain a healthy balance of bacteria in your vagina and gut, which may help prevent UTIs.
- Treat vaginal dryness. If you’re experiencing vaginal dryness, talk to your doctor about vaginal estrogen therapy. This treatment can help restore moisture and prevent UTIs.
Final Thoughts
While lube itself doesn’t cause UTIs, certain ingredients in some lubes can definitely increase your risk. It’s all about being smart about what you’re putting in and around your body.
When choosing a lubricant, pay close attention to the ingredient list, pH levels, and osmolality. Prioritize good hygiene, drink plenty of water, and always pee after sex.
If you’re prone to UTIs, or if you have any concerns, don’t hesitate to talk with your doctor or another healthcare provider. They can offer personalized advice to keep you healthy and comfortable.
