Keto And Urination: What You Need To Know

The keto diet is a popular, low-carb, high-fat diet that aims to put your body into a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. One of the most common side effects of starting a keto diet is increased urination, which can be alarming for some people. So, will keto cause changes in the way you urinate?

Frequent urination

When starting a keto diet, it is normal to experience frequent urination. This is due to the body getting rid of its glycogen stores, which hold onto water molecules in the muscles and liver. As the body burns through the glycogen, it releases the stored water, which ends up in the bladder. This is especially common during the first week or two of starting the diet.

The keto diet can also affect electrolyte balance, particularly sodium levels. When carb intake is reduced, the body excretes more sodium along with the water linked to glycogen, which can contribute to increased urination in the early stages of the keto diet. It is important to stay hydrated and ensure adequate electrolyte intake during this time.

The increased urination associated with the keto diet can also be explained by the drop in insulin levels that occurs when carb intake is reduced. Insulin normally signals the kidneys to retain sodium and water, so when insulin levels drop, the kidneys release more sodium and water, leading to increased urination. This is often when people start to see significant weight loss.

It is worth noting that frequent urination can also be a sign of dehydration, especially if it is accompanied by other symptoms such as fatigue, dizziness, or constipation. In this case, it is important to increase fluid intake and ensure adequate electrolyte intake to prevent further complications.

Overall, while frequent urination is a common side effect of the keto diet, it is generally not something to worry about. However, if it becomes bothersome or is accompanied by other symptoms, it may be a good idea to consult a healthcare professional.

The Glycogen Flush-Out

When you start a keto diet, your body uses up its carb stores, called glycogen. This glycogen is stored in your muscles and liver and it loves water—a lot of water. As your body burns through the glycogen, it releases all that built-up water, which ends up in your bladder, causing frequent trips to the bathroom, especially in the first few days.

This is a completely normal part of the transition to a low-carb, high-fat lifestyle. It's also why people often see dramatic weight loss during the first week of keto. In addition to getting rid of glycogen, your body is also flushing out excess water and electrolytes, which can make your kidneys work overtime.

To stay on top of your hydration and keep your body functioning optimally, it's important to drink plenty of water and replenish your electrolytes. Focus on foods packed with potassium, magnesium, and sodium, such as leafy greens and avocados. You can also consider taking an electrolyte supplement, especially if you're physically active.

While the increased urination may be a bit inconvenient, it's a sign that your body is adjusting to its new fuel source and finding its balance. As you continue on your keto journey, your bathroom habits will likely normalize as your body adapts to this new way of eating.

Dehydration and flu-like symptoms

The keto diet can lead to dehydration and flu-like symptoms, which is often referred to as the "keto flu". This is due to the body adapting to a low-carb state and burning ketones for energy instead of glucose. The symptoms of keto flu include frequent urination, fatigue, dizziness, irritability, nausea, muscle soreness, headaches, weakness, and constipation.

The frequent urination associated with the keto diet is a result of the body burning through glycogen stores, which hold onto water molecules in the muscles and liver. As the body breaks down fat, ketones are produced and removed through urination, leading to a loss of fluids and electrolytes. This can further contribute to dehydration and the exacerbation of flu-like symptoms.

To prevent dehydration, it is important to increase fluid intake and ensure adequate electrolyte consumption. Electrolytes such as sodium, potassium, and magnesium can be obtained through foods like leafy greens, avocados, and salt. Additionally, drinking plenty of water can help flush out toxins and keep the body hydrated.

The keto flu is typically temporary and usually lasts about a week. However, if you are experiencing severe or prolonged symptoms, it is recommended to consult a healthcare professional.

It is worth noting that the keto diet can also affect your electrolyte balance, especially sodium levels. The reduction in carb intake can lead to a decrease in sodium levels, as the body excretes more sodium along with the water linked to glycogen. This can contribute to increased urination and a feeling of thirst during the early stages of the keto diet. Therefore, maintaining proper hydration and electrolyte balance is crucial to avoid dehydration and mitigate flu-like symptoms.

Increased urination at night

While the keto diet can have many benefits, it can also cause some disruptions to your daily routine, especially in the first few weeks. One of the most common side effects of starting a ketogenic diet is an increase in urination, which can be disruptive if it occurs at night.

When you start a keto diet, your body transitions from using carbohydrates for fuel to burning fat. This is a significant metabolic change and can lead to a range of side effects, including frequent urination. The first few days of keto can be the most noticeable for this side effect as your body uses up its stored carbohydrates, or glycogen. Glycogen holds onto water molecules in your muscles and liver, and as your body burns through this glycogen, it releases all that water, which ends up in your bladder.

Additionally, the keto diet can affect your electrolyte balance, particularly sodium levels. When you drastically reduce carbohydrates, your body excretes more sodium along with the water associated with glycogen, which can also contribute to increased urination in the early stages of keto.

Managing Night-Time Urination

If you find yourself needing to get up in the night to urinate more often, there are a few things you can do to manage this side effect. Firstly, ensure you are staying adequately hydrated by drinking plenty of water throughout the day. This may seem counterintuitive, but dehydration can worsen this side effect and lead to other issues such as constipation and fatigue.

You should also focus on consuming enough electrolytes, including sodium, potassium, and magnesium. These can be obtained through foods such as leafy greens, avocados, and salt. Some people on the keto diet also find electrolyte supplements helpful, especially after intense exercise.

The good news is that this side effect is usually temporary. Most people find that their bathroom habits return to normal as their body adapts to its new fuel source. This process can take a few weeks, and in the meantime, it might be a good idea to invest in a bigger water bottle!

If you are concerned about any changes in your bathroom habits, it is always a good idea to consult your doctor. They can advise you on whether these changes are normal and expected or indicative of a more serious issue.

Changes in urine colour

The keto diet can cause changes in the colour of your urine. While not everyone experiences side effects when starting a ketogenic diet, changes in urine colour can occur, alongside increased urination.

When you start a low-carb diet, your body uses up its carb stores, called glycogen. Glycogen holds onto water molecules in your muscles and liver. As your body burns through the glycogen, it releases all that built-up water, which ends up in your bladder. This can result in frequent urination, especially in the first few days of the keto diet.

The keto diet can also affect your electrolyte balance, particularly sodium levels. When you drastically reduce carbs, your body excretes more sodium along with the water linked to glycogen. This can also contribute to increased urination in the early stages of keto.

It's important to stay hydrated and ensure adequate electrolyte intake when on the keto diet. Aim for at least 2 litres of water per day and include foods rich in potassium, magnesium, and sodium. Leafy greens, avocados, and a pinch of salt can help maintain electrolyte balance.

The changes in urine colour on the keto diet are typically due to the body adjusting to a new fuel source and finding its balance. As you continue on your keto journey, your bathroom habits will likely normalise as your body adapts.

If you notice any concerning changes in your urine colour or experience discomfort, it's always a good idea to consult your doctor. They can provide guidance and advice tailored to your specific situation.
