Bladder stones are hard mineral deposits that form inside the bladder, causing pain and difficulty urinating. They are more common in men over 50, especially those with an enlarged prostate. While there are various causes, one of the main contributors is diet, which can increase the risk of bladder stone formation by altering urine chemistry. A healthy bladder stone diet should be high in fiber, obtained from whole grains, fruits, and vegetables, and should limit certain foods and nutrients that promote stone development.
Characteristics of diets that cause bladder stones in men
| Characteristics | Values |
|---|---|
| Water Intake | Dehydration and insufficient water intake can increase the risk of bladder stones. It is recommended to drink between 64-96 ounces of water per day. |
| Sodium Intake | High sodium intake may increase the risk of bladder stones by increasing calcium excretion in urine. It is recommended to limit sodium intake to 2,300 milligrams daily. |
| Animal Protein | Excessive intake of red meat and other animal proteins can increase the risk of bladder stones. It is recommended to limit animal protein and opt for plant-based proteins instead. |
| Caffeine and Alcohol | Alcoholic and caffeinated beverages may deplete the body's water content, increasing the risk of bladder stones. It is recommended to limit caffeine and alcohol intake. |
| Sugar | High sugar intake may promote bladder stone formation. It is recommended to reduce consumption of sugar and sugary foods and drinks. |

Dehydration increases the risk of bladder stones
Bladder stones are hardened mineral clumps that form in the bladder. They are caused when the bladder doesn't fully empty, and the remaining urine crystallises and forms stones. Dehydration increases the risk of bladder stones because drinking water and other fluids helps to dilute the minerals in urine and flush out the bladder. When the body is dehydrated, urine becomes more concentrated, and the likelihood of minerals binding together and forming bladder stones increases.
Drinking water is one of the best ways to prevent bladder stones. Water helps to dilute substances in urine that can lead to stone formation. Aiming for at least eight 8-ounce cups of water per day is recommended, but this may vary depending on age, climate, exercise, and other factors. Staying properly hydrated ensures that urine can effectively flush out minerals and prevent them from collecting in the bladder.
In addition to water, consuming citrus fruits like lemons can also help prevent bladder stones. Citric acid in lemon juice makes urine more basic and less acidic, inhibiting certain types of stones from forming. It is also beneficial to eat plenty of fruits and vegetables, as they have a high water content that contributes to overall hydration and kidney health.
A healthy diet is crucial in maintaining hydration and preventing bladder stones. A diet high in fibre from whole grains, fruits, and vegetables is recommended. It is also important to limit animal protein, sodium, and oxalate. Foods high in oxalate can increase oxalate levels in urine, promoting stone formation. Caffeine and alcohol should be consumed in moderation, as they can deplete the body's water content, leading to dehydration.
While dehydration is a significant risk factor for bladder stones, other factors also contribute to their formation. Men over 50 are more prone to developing bladder stones due to an increased likelihood of an enlarged prostate, which can partially block the urethra and make it difficult to empty the bladder completely. Nerve damage, bladder surgery, and kidney stones that cannot pass out of the bladder are also risk factors for bladder stones.

High-sodium diets may increase the risk of bladder stones
Bladder stones are hardened mineral clumps that form in the bladder. They cause pain and trouble urinating. While anyone can get bladder stones, men over 50 are more likely to develop them. This is because the prostate tends to get bigger with age, which can partially block the urethra, making it difficult to completely empty the bladder. Stones can form when urine sits in the bladder for too long.
Diet plays a large role in bladder stone development and prevention. Consuming a healthy bladder stone diet is important to reduce your risk. A diet high in sodium may increase the risk of bladder stones. This is because sodium causes the kidneys to excrete more calcium in the urine. Sodium and calcium share the same transport system in the kidneys, so eating high-sodium foods will increase calcium leakage in the urine. Therefore, a high-sodium diet can increase the chances of developing bladder stones.
High-sodium diets can also increase the risk of bladder stones by causing dehydration. Not drinking enough fluids can lead to mineral build-up and bladder stones. High-sodium diets often include processed foods, restaurant-prepared meals, and fast food, which tend to be high in "hidden" sodium. These foods are often also high in oxalates, which increase levels of oxalates in the urine. Calcium-oxalate stones are the leading type of kidney stone.
To prevent bladder stones, it is important to drink plenty of water. Water helps to dilute the substances in urine that lead to stones and flush out the bladder. Aim for at least eight 8-ounce cups of water per day. It is also important to reduce sodium intake and limit animal protein.

Excessive animal protein can boost the risk of bladder stones
Bladder stones are hardened mineral clumps that form in the bladder. They are often asymptomatic and can pass out of the body during urination. However, larger bladder stones can cause pain, difficulty urinating, and other complications. While anyone can get bladder stones, men over 50 are more prone to developing them due to an increased risk of an enlarged prostate, which can partially block the urethra and make it challenging to empty the bladder completely.
Diet plays a significant role in bladder stone formation. A poor diet can alter urine chemistry, increasing the likelihood of bladder stones. Dehydration, in particular, is a key factor, as it can lead to mineral buildup in the bladder. Therefore, it is essential to stay hydrated and aim for at least eight glasses of water per day.
Excessive animal protein consumption, especially red meat, has been linked to an increased risk of bladder stones. A positive association has been observed between a higher intake of nondairy animal protein and the formation of kidney stones, which are similar to bladder stones. Each additional 100 grams of red meat consumed significantly raises the likelihood of kidney stones. Organ meats, such as liver, heart, and kidney, as well as anchovies, sardines, mackerel, and other fish, are among the foods highest in purines.
To reduce the risk of bladder stones, it is advisable to limit animal protein intake and opt for more plant-based protein sources, such as beans, chickpeas, lentils, and peas. A diet high in fiber from whole grains, fruits, and vegetables is also recommended, as it can help regulate digestion and promote a healthy bladder. Additionally, caffeine and alcohol consumption should be limited, as they can contribute to dehydration and increase the risk of bladder stone formation.

Bladder stone prevention through diet and lifestyle changes
Bladder stones are hardened mineral clumps that form when the bladder doesn't fully empty itself. They can cause pain and difficulty urinating. Bladder stones can be prevented through diet and lifestyle changes, such as:
Staying hydrated
Drinking plenty of water is one of the most important ways to prevent bladder stones. Water helps to dilute the substances in urine that can lead to stone formation and ensures that you urinate frequently, preventing a build-up of minerals. Aim for at least eight 8-ounce glasses of water per day, or about two to three litres.
Increasing citric acid intake
Adding citric acid to your diet can help prevent stone formation. Squeeze fresh lemon or orange juice into your water, or incorporate low-sugar/no-sugar lemonade or orange juice into your diet.
Eating calcium-rich foods
Eating calcium-rich foods can help prevent bladder stones. Good sources of calcium include dairy products such as milk, yoghurt, and some cheeses. The recommended calcium intake to prevent calcium stones is 1000-1200 mg per day.
Reducing sodium intake
A high-sodium diet can increase your risk of bladder stones by causing your kidneys to excrete more calcium in the urine. Sodium is often found in canned, commercially processed, restaurant-prepared, and fast food.
Limiting animal protein
A diet high in animal protein can increase the risk of bladder stone formation. Foods highest in purines, which are broken down into uric acid, include organ meats (such as liver, heart, and kidney), anchovies, sardines, mackerel, codfish, herring, mussels, scallops, shrimp, veal, and bacon.
Limiting oxalate and vitamin C
If you are at risk for calcium oxalate stones, limit your intake of oxalate and vitamin C. Foods high in oxalate include spinach, beets, rhubarb, nuts, wheat bran, buckwheat, and chocolate.
Reducing caffeine and alcohol consumption
Alcoholic and caffeinated beverages may deplete your body's water content, increasing the risk of bladder stone formation.
Increasing plant-based protein
Eating more plant-based protein, such as beans, chickpeas, lentils, and peas, can help prevent bladder stones.
Increasing fish oil intake
Consuming more fish oil can help decrease urinary citrate and oxalate levels. Good sources of fish oil include salmon, sardines, and mackerel.
It is important to note that individual dietary needs may vary, and it is always recommended to consult with a healthcare professional before making any significant diet or lifestyle changes.

Foods that help prevent bladder stones
Bladder stones are hardened mineral clumps that form in the bladder. They are often asymptomatic and can pass out of the body without treatment. However, larger bladder stones may require medical intervention.
The primary cause of bladder stones is urine left in the bladder, but diet can also play a role in their formation. Dehydration, for example, can cause minerals to build up and lead to bladder stones. Therefore, it is important to maintain a healthy diet and stay hydrated to prevent bladder stones from forming.
- Increase fluid intake: Aim to consume between eight and twelve cups of fluid per day, with a focus on drinking water. Water helps to dilute the substances in urine that lead to stones and flushes out your bladder.
- Consume citrus fruits: Lemon water or other citrus fruits and juices can increase urinary citrate levels, which help to break up existing stones and lower the chance of new stone development.
- Eat more plant-based protein: Include beans, chickpeas, lentils, and peas in your diet. These foods are rich in magnesium and fiber, which assist with digestion and lower the risk of urinary issues.
- Increase your intake of fish oil: Consuming salmon, sardines, and mackerel can help decrease urinary citrate and oxalate levels.
- Limit caffeine and alcohol: These beverages may increase urine output, but they can also deplete your body's water content.
- Reduce consumption of sugar and animal protein: A diet high in sugar and animal protein may lead to the formation of bladder stones. Limit your intake of red meat, poultry, eggs, seafood, and sugary foods and drinks.
- Choose low-sodium options: Sodium can increase the risk of certain types of bladder stones. Opt for fresh, low-sodium foods to help lower calcium leakage in the urine and maintain healthy blood pressure.
- Include cruciferous vegetables: Vegetables like Brussels sprouts, broccoli, and kale are rich in potassium and antioxidants. They help decrease calcium loss and prevent bladder stones, as well as providing potential protection against bladder, prostate, and kidney cancers.
