What You'll Learn
Reduce protein intake
Creatinine is a waste product that the body produces when you use your muscles. It is a natural byproduct of the body's digestion of protein. High levels of creatinine in the blood or urine can indicate that the kidneys are not filtering the blood effectively, which may be a sign of chronic kidney disease.
High levels of creatinine can be caused by a high intake of protein, particularly cooked red meat. This is because the heat from cooking causes the creatine found in meat to produce creatinine. As such, reducing your protein intake can help lower creatinine levels. For people with CKD, eating a high-protein diet can contribute to elevated BUN and creatinine levels. This is because these lab markers indicate protein intake and protein stores in the body, which damaged kidneys are unable to remove. Therefore, restricting protein intake to about 0.6-0.8 grams per kilogram of body weight can be an effective way to slow the progression of CKD.
It is important to note that creatinine levels can also be affected by other factors, such as strenuous exercise, dehydration, and the use of certain medications or supplements. If you have high creatinine levels, it is recommended to work with a healthcare professional to develop a treatment plan and determine if any lifestyle changes are appropriate for you.

Limit cooked red meat
Creatinine is a waste product from the body's natural digestion of protein. It is produced when creatine, a natural compound made in the liver, is transported to the muscles and used for energy. When creatine is used as energy, it is degraded into creatinine, a metabolic byproduct.
Consuming cooked red meat can cause a temporary increase in creatinine levels. The heat from cooking causes the creatine found in meat to produce creatinine. People following diets very high in red meat or other protein sources, including dairy products, may have higher creatinine levels than those who eat less of these foods. Therefore, limiting cooked red meat may help lower creatinine levels.
If you eat a lot of red meat, you can try switching to more vegetable-based dishes. For example, instead of eating a beef burger, you could try a vegetarian alternative. Research has shown that people with high creatinine levels who increased their fiber intake saw significant reductions in their creatinine levels.
It is important to note that while limiting cooked red meat may help lower creatinine levels, it is not the only factor contributing to high creatinine levels. Strenuous exercise, dehydration, certain medications, and supplements can also cause temporary increases in creatinine levels. If you are concerned about your creatinine levels, it is best to consult a healthcare professional for personalized advice and guidance.

Stay hydrated
Staying hydrated is crucial for maintaining optimal health. Water is essential for many bodily functions, including waste removal, nutrient transport, joint and organ protection, and maintaining body temperature. Dehydration can lead to increased creatinine levels, a waste product in the blood that can indicate kidney issues.
Water is the best way to stay hydrated. It is caffeine-free, calorie-free, and readily available for most people. The recommended daily water intake varies depending on factors such as activity level, health, height, weight, and gender. As a general guideline, men are advised to drink approximately 3 liters of water per day, while women should aim for 2.2 liters. However, it's important to listen to your body and adjust your water intake accordingly.
To ensure adequate hydration, carry a water bottle with you and aim to drink throughout the day. If you're concerned about the environmental impact of plastic water bottles, opt for a reusable bottle and fill it with filtered water. Adding fresh herbs, fruits, or vegetables like mint, cucumber, or lemon wedges can enhance the flavor and make water more appealing.
In addition to water, you can also increase your fluid intake by consuming fruits and vegetables with high water content, such as watermelon, strawberries, cucumbers, and celery. These foods not only contribute to hydration but also provide essential vitamins and minerals.
While water should be your primary source of hydration, other beverages can also contribute to your fluid intake. Herbal teas, seltzer water, and diluted squash drinks (reduced in sugar) are suitable alternatives. Caffeinated drinks like coffee and tea can be consumed in moderation, keeping in mind that caffeine has a mild diuretic effect. It's best to avoid sugary drinks like soda or juice, as they are high in simple sugars and calories, which can negatively impact your health.

Monitor salt and potassium intake
To monitor salt and potassium intake, it is important to understand the implications of high salt and potassium levels in the body.
Firstly, high salt intake can lead to fluid retention or swelling, which puts a strain on the kidneys. This is because the body holds onto more water when there is excess salt, potentially leading to kidney complications. Therefore, it is advisable to limit the addition of salt during cooking or at the table and opt for herbs and other sodium-free seasonings.
Secondly, while potassium is essential for many body functions, people with kidney disease are at risk of having potassium levels outside the goal range, which can be either too high or too low. High potassium levels, known as hyperkalemia, can lead to complications affecting the kidneys. On the other hand, low potassium levels, or hypokalemia, can also have adverse effects. Thus, it is crucial to maintain potassium levels within the goal range.
To manage salt and potassium intake effectively, consider the following strategies:
- Consult a dietitian or healthcare professional: They can guide you in creating a personalised eating plan that takes into account your specific health needs and goals. A dietitian can help you understand food labels, portion sizes, and weekly meal planning to ensure you're getting the right amount of salt and potassium.
- Practice portion control: Eating smaller portions of protein-rich foods can help reduce the burden on your kidneys.
- Choose fresh or frozen foods: Opt for fresh or frozen fruits and vegetables instead of canned goods, as canned foods can have high salt and potassium levels. If you do use canned goods, remember to drain and rinse the contents with water to reduce salt and potassium intake.
- Limit processed foods: Many packaged and ultra-processed foods contain hidden sodium, so it's important to read labels carefully.
- Leach high-potassium vegetables: If you want to include high-potassium vegetables in your diet, consider leaching them to reduce their potassium content. This involves soaking them in warm unsalted water for a minimum of two hours, using ten times the amount of water as vegetables.
- Monitor your levels: Work closely with your doctor to regularly check your potassium levels through blood tests. This is important because people with high potassium levels may not always exhibit symptoms.

Exercise regularly
Exercise is an important part of maintaining a healthy lifestyle and can help manage your BUN and creatinine levels. Creatinine is a waste product that is generated when you use your muscles. It is produced when creatine, a natural compound made in the liver, is transported to your muscles and used for energy.
Regular exercise can help improve overall health and kidney function, especially for individuals with diabetes. It can help control blood pressure, manage weight, and reduce the risk of chronic conditions affecting kidney health. Aim for at least 30 minutes of moderate exercise most days of the week. However, it is important to note that acute and prolonged strenuous exercise can lead to a temporary increase in creatinine levels in the blood. Therefore, it is recommended to consult a doctor if you are engaging in strenuous exercise and have a risk of kidney disease to ensure that your exercise routine is suitable.
Additionally, staying hydrated is crucial when exercising, as dehydration can cause an increase in creatinine levels. Make sure to drink plenty of water, especially when exercising or in hot temperatures. Most adults need around six to eight glasses of water daily, but you may need to drink more depending on your level of activity and the climate. If you have difficulty drinking enough water, try adding slices of lemon or cucumber to make it more appealing, or drink other fluids like seltzer water or herbal teas.
Incorporating regular exercise into your routine and maintaining proper hydration can help manage your BUN and creatinine levels, contributing to improved kidney health and overall well-being.
