Overactive Bladder Diet Essentials: Tips and Strategies from The Bladder Dietitian™

Living with an overactive bladder (OAB) can really throw a wrench into your daily life, messing with everything from work to socializing. Trust me, I can relate—I’m an Interstitial Cystitis (IC) Warrior myself, dealing with a bladder condition that can be just as disruptive. But here's the thing: managing OAB isn't just about popping a pill. It's about taking a holistic approach, and your diet plays a huge role in how you feel. That's where I come in. As The Bladder Dietitian™, I'm here to give you the lowdown on what works when it comes to your OAB diet. My goal? To help you kick those pesky OAB symptoms to the curb so you can get back to living your life to the fullest.

Understanding Overactive Bladder

When it comes to diagnosing overactive bladder, there are three main types: stress, urgency, and overflow. Sometimes you might even have a mix of these, which is called mixed OAB. It's a pretty common condition, affecting millions of people worldwide, with women being more likely to deal with it.

Many underlying factors can cause OAB, but let’s focus on the major risk factors:

  • Age

  • Obesity

  • Pregnancy (& mode of birth)

  • Family history

  • Certain medical conditions, like diabetes

  • High impact exercise

  • Diet

  • Smoking

  • Ethnicity

  • Microbiome of the urinary tract

While we can't control some of these risk factors, I can tell you that tweaking your diet is a proven overactive bladder therapy that you can put into action right away. Let's dig into the research and see what dietary changes can help with overactive bladder treatment.

The Role of Diet For Overactive Bladder

Research shows that giving the Mediterranean diet a go can really help with managing OAB symptoms. Unlike the typical Western diet, the Mediterranean diet focuses on whole foods like fruits, veggies, whole grains, nuts, and healthy fats, while cutting back on red meat and processed foods.

The Mediterranean diet has also been linked to lowering the risk of various diseases and obesity. This is important because being overweight, especially carrying extra belly fat, can worsen OAB in women

Various foods on the Mediterranean diet

Loading up on certain nutrients can help stave off OAB. Vitamin D, protein, and potassium, in particular, have been shown to do wonders in preventing and easing OAB symptoms.

When it comes to foods that trigger OAB, there’s been some conflicting research about caffeine and alcohol. Right now there isn’t a set consensus on the recommended intake of either (including or avoiding) when it comes to overactive bladder. 

We do know, though, that artificial sweeteners can have a negative impact on OAB.

There was a recent research study done that investigated if drinking more artificially sweetened beverages is associated with OAB symptoms.


They found that women who drank one or more servings of “diet” drinks per day had a 10% higher chance of reporting OAB symptoms compared to those who drank less than one serving per week.

Another study found that cutting back on daily salt intake can help improve symptoms in people with overactive bladder, especially if they were consuming too much salt to begin with.

Considering all this information, you might be wondering, how do I combine all of this information and follow the best diet for OAB? 

Let’s dive into my recommendations for the best overactive bladder diet—a natural approach to ease your symptoms that can complement other treatments.

Key Dietary Strategies for Overactive Bladder

The best diet for OAB is the Mediterranean and is the first-line diet recommended to treat this condition. 

To get started with the Mediterranean diet and make sure you're getting all the right nutrients for treating the symptoms of an OAB, here's the best approach:

  • Increase Vitamin D intake: Include foods rich in vitamin D such as fatty fish, fortified dairy products, and eggs.

  • Get adequate protein: Incorporate lean sources of protein such as chicken, turkey, fish, beans, and lentils into your meals.

  • Add more B Vitamins: Include sources of B6 and niacin, such as chickpeas, fish, poultry, potatoes, bananas, brown rice, and peanuts.

  • Include potassium: Consume potassium-rich foods like bananas, oranges, spinach, sweet potatoes, and avocados.

  • Reduce salt intake: Limit processed foods and opt for fresh, whole foods to lower your sodium intake. 

  • Use caution with caffeine & alcohol: If you consume either, pay attention to your OAB symptoms and adjust accordingly if you suspect a sensitivity to either one.

  • Remove artificial sweeteners: Skip “diet” drinks (which contain artificial sweeteners) and choose water or herbal teas for your beverage. Instead of using artificial sweeteners like Splenda or Equal, go for real sugar and make the following adjustments:

  • Reduce sugar in recipes, choose naturally lower-sugar foods, and adjust your serving size of sugar-containing foods if you’re carb counting.

  • Test tomatoes & spicy foods: Although current research findings aren't strong for these, some published articles mention tomatoes and spicy food as potential OAB irritants. Pay attention to your overactive bladder symptoms and limit (or omit) these foods if you suspect a sensitivity.

Now let’s implement the above recommended dietary strategies and see how to include these foods daily to help control overactive bladder symptoms.
