Keto And Kidney Stones: Is There A Link?

The ketogenic diet is a low-carb, high-fat diet that has become popular for weight loss. However, it has been linked to an increased risk of kidney stones. Kidney stones are a well-known side effect in children who follow a keto diet for epilepsy, with 13 out of 195 subjects developing kidney stones in one study. This risk is thought to be due to the diet's restriction of fruits and vegetables, which are important for kidney stone prevention as they produce alkali, citrate, and potassium in the body. Additionally, the keto diet can cause a dramatic drop in urine pH due to excess protein intake, making uric acid and calcium oxalate kidney stones more likely. While some studies suggest that keto may be protective against gout, a form of arthritis, others indicate that people may experience an increased risk of gout when they first start the diet due to increased uric acid levels.

The keto diet can cause kidney stones in children with epilepsy

The ketogenic diet is a high-fat, low-carbohydrate diet that has been used to control seizures in people with epilepsy since the 1920s. While it has proven effective in reducing seizures, the keto diet is not without risks. One such risk is the development of kidney stones.

Kidney stones are a well-documented potential side effect of the keto diet. This is due to several factors. Firstly, the diet can cause metabolic acidosis, which reduces calcium reabsorption in the renal tubules, leading to increased urinary calcium excretion. Secondly, keto can induce hypocitraturia, a condition where there are low levels of citrate in the urine. Citrate normally binds to calcium, preventing the formation of kidney stones. Thirdly, acidosis caused by the diet can lead to persistently low urinary pH, which facilitates the formation of uric acid crystals, which can act as a nucleus for calcium stone formation. Lastly, dehydration is a significant factor in kidney stone formation, as ketosis has been shown to interfere with the normal thirst mechanism.

Research has shown that kidney stones are a significant complication of the ketogenic diet in children with epilepsy. In one study, 13 out of 195 subjects developed kidney stones while following the keto diet as a treatment for epilepsy. Another study reported that renal calculi developed in 3-10% of children on the ketogenic diet, compared to 1 in several thousand in the general population. A separate case study described a 5-year-old girl who developed a renal stone while following the keto diet to treat refractory seizure disorder.

The risk of kidney stone formation on the keto diet can be mitigated through proper hydration and urine alkalization using oral potassium citrate. Maximizing fluid intake and making the urine less acidic can help prevent the development of renal stones. Regular urinary studies, including calcium-to-creatinine ratio and ultrasonography, are recommended to detect this possible complication in children on the ketogenic diet.

The keto diet may increase the risk of kidney stones in adults

The ketogenic diet is a low-carb, high-fat diet that has become popular for weight loss. However, the diet has some risks, and one of them is kidney stones. Kidney stones are a well-noted potential side effect of the ketogenic diet, especially in children. Past research has shown that among children following the keto diet as a treatment for epilepsy, 13 out of 195 subjects developed kidney stones.

So, what is the link between the keto diet and kidney stones? One reason may be that keto diets are usually lacking in fruits and vegetables, which help prevent kidney stones by producing alkali that neutralises acid produced from protein metabolism. Additionally, fruits and vegetables are a main source of potassium in our diet, and potassium is an inhibitor of kidney stones.

Another reason for the link between keto and kidney stones could be excessive protein intake. The keto diet is high in animal protein, which can cause blood and urine to become more acidic, leading to increased excretion of calcium in the urine. This can increase the risk of kidney stone formation.

Furthermore, keto diets may not provide enough calcium, as milk and yoghurt are usually not allowed on this diet. Calcium reduces the amount of oxalate absorbed from food, and eating calcium-rich foods is key to kidney stone prevention.

In summary, while the keto diet may be effective for weight loss, it also has some potential risks, including an increased risk of kidney stones in adults. This risk may be due to a lack of fruits and vegetables, excessive protein intake, and inadequate calcium intake. Therefore, it is important to be aware of these risks and take precautions if considering the keto diet.

The keto diet may cause a drop in urine pH, leading to kidney stones

The keto diet is a low-carb, high-fat diet that is commonly used for weight loss. It is also used as a treatment for epilepsy, especially in children. The diet typically restricts carbohydrate intake to less than 50 grams per day and calls for a moderate increase in protein and fat intake. This can lead to a state of ketosis, where the body relies primarily on fat for energy instead of carbohydrates. While the keto diet can be effective for weight loss, it also carries certain risks, including kidney stones.

Kidney stones are a well-known side effect of the keto diet, especially in children who follow the diet as a treatment for epilepsy. In one study, 13 out of 195 children following a keto diet developed kidney stones, and children who took potassium citrate supplements had a decreased likelihood of developing kidney stones. The keto diet can cause a drop in urine pH, leading to an increased risk of kidney stones. This is because a high intake of animal protein and a lack of fruits and vegetables can make the blood and urine more acidic, leading to increased excretion of calcium in the urine.

The keto diet can also reduce the amount of citrate in the urine, which is a powerful inhibitor of kidney stone formation. Citrate is found primarily in fruits, which are restricted on the keto diet. Additionally, the keto diet may cause excessive protein intake, which can further increase the acidity of the urine and the risk of kidney stone formation. It is important to note that not all keto diets are equal, and the risk of kidney stones may vary depending on the specific foods included in the diet.

To reduce the risk of kidney stones while on the keto diet, it is important to stay hydrated by drinking plenty of water. Additionally, eating more vegetables, especially those that are low in carbohydrates, can help neutralize the acid produced by protein metabolism. It is also important to monitor urine pH and ensure it stays within a healthy range. For those at risk of kidney stones, a prescription for potassium citrate may be recommended.

The keto diet may cause excess uric acid, increasing the risk of kidney stones

The keto diet is a low-carb, high-fat diet that is commonly used for weight loss. It can, however, cause excess uric acid, increasing the risk of kidney stones. Kidney stones are a well-noted potential side effect of the diet. Research has shown that among children following the keto diet as a treatment for epilepsy, 13 out of 195 subjects developed kidney stones. This is a significant number and highlights the potential risks of the diet.

The keto diet can cause a build-up of uric acid in the body, which can lead to the formation of kidney stones. This is because the diet is high in animal protein, which can cause blood and urine to become more acidic. This increased acidity can lead to several issues, including an increased excretion of calcium in the urine. Studies have also shown that the keto diet reduces the amount of citrate in the urine. Citrate is important as it can bind to calcium and prevent the formation of kidney stones. Therefore, reduced levels of citrate may also increase the risk of kidney stone development.

In addition, the keto diet is often lacking in fruits and vegetables, which are important sources of potassium. Potassium is crucial for maintaining the body's acid-base balance and preventing the formation of kidney stones. By restricting these food groups, the keto diet may further increase the risk of kidney stone formation.

Furthermore, the keto diet can also lead to dehydration, which is another risk factor for kidney stone development. Dehydration can cause minerals and salts to concentrate in the urine, increasing the likelihood of stone formation. Therefore, it is important for individuals following the keto diet to ensure adequate hydration.

While the keto diet may offer certain benefits, it is important to be aware of the potential risks associated with it. Excess uric acid and the formation of kidney stones are significant side effects that should be carefully considered before starting the diet.

The keto diet may cause dehydration, a risk factor for kidney stones

The keto diet is a high-fat, low-carb approach to losing weight that has become one of the most popular ways to shed pounds quickly. However, it is important to be aware of the risks before giving it a shot. One of the potential dangers of the keto diet is that it may cause dehydration, which is a risk factor for kidney stones.

The ketogenic diet is a high-fat, low-carbohydrate diet that was initially introduced in the early 19th century as a treatment for epilepsy. Today, it is touted as a remedy for everything from infertility to type 2 diabetes and is promoted as a way to lose weight quickly. On the keto diet, carbohydrate intake is typically limited to fewer than 50 grams per day, which can be a shock to the body as it depletes its carb stores. This low level of carbohydrates puts the body into a state of ketosis, where it relies primarily on fat for energy instead of carbs.

As the body adjusts to using ketones and fats as its primary energy source during the early stages of the keto diet, it may experience flu-like symptoms such as headaches, dizziness, fatigue, nausea, and constipation. These symptoms are due in part to dehydration and electrolyte imbalances. To help alleviate these symptoms, it is important to stay hydrated and eat foods rich in sodium, potassium, and other electrolytes.

Dehydration is a risk factor for kidney stones because it can lead to the concentration of certain substances in the urine, such as calcium, oxalate, and uric acid, which are the most common chemicals found in kidney stones. When the body is dehydrated, it does not have enough water to dilute these substances, increasing the risk of them forming stones in the kidneys.

Kidney stones are a well-known side effect of the keto diet, especially in children who follow the diet as a treatment for epilepsy. In one study, 13 out of 195 children following the keto diet developed kidney stones, which is a rate of about 25%. However, it is important to note that this study only looked at a small number of children, and more research is needed to determine the true prevalence of kidney stones in adults following the keto diet.

How to Prevent Kidney Stones on the Keto Diet

If you need to follow the keto diet for a medical condition, there are some things you can do to help prevent kidney stones:

• Drink plenty of water to stay hydrated and dilute substances in the urine.
• Eat as many low-carbohydrate vegetables as possible to increase alkali production and neutralize acid in the body.
• Limit your sodium intake to no more than 2,300 mg per day to reduce the amount of calcium in your urine.
• Consider taking a potassium citrate supplement, as this has been shown to decrease the likelihood of kidney stones.
