What Are The Complications Of High Potassium
Having too much potassium in your blood can be dangerous. Potassium affects the way your heartâs muscles work. When you have too much potassium, your heart may beat irregularly, which in the worst cases can cause heart attack.
If you think you are having a heart attack, call 911 for emergency help.
Some of the most common signs of heart attack are:
- Feelings of pressure, pain, or squeezing in your chest or arms
- Stomach pain or nausea

What Is High Potassium
- High levels of potassium in the blood is unpredictable and can be life-threatening. It can cause serious heart problems and sudden death.1-3 There are often no warning signs, meaning a person can have high potassium without knowing it.4
- If symptoms do occur, they are often nonspecific such as heart palpitations, nausea, weakness, or paresthesia.5 Paresthesia is an abnormal sensation of tingling, numbness, or burning that is usually felt in the hands, feet, arms, or legs.
- Blood potassium > 5.0 indicates potassium imbalance.6 Arbitrary thresholds are used to indicate degree of severity, such as mild , moderate , and severe .5,7 Clinical severity is determined by the speed of onset, magnitude of the severity, and the development of clinical findings.4
- Hyperkalemia is further classified as chronic or acute.5 Acute hyperkalemia represents a single event, occurring over hours to days and usually requires emergency treatment. Chronic hyperkalemia develops over the course of weeks to months, may be persistent or develop periodically, and requires ongoing outpatient management.
- A person’s potassium levels can be easily checked with a simple blood test. The healthcare provider draws a small blood sample, and sends it to a laboratory for analysis. This is usually part of a routine blood test given during a physical exam. It is often performed as part of a basic metabolic panel, which checks for several conditions, including kidney function and diabetes.
Low Potassium Regimens For Pragmatic Management Of Ckd Patients With Hyperkalaemia
Nutritional therapy in CKD is very complex, as it has to consider concomitantly the intake of protein, energy, sodium, phosphorus and potassium. Individualized nutritional education programs and regular counselling are all important aspects of clinical management, which also look to improve patients lifestyle. Dietary interventions require the active participation of patients and their relatives and caregivers. Recommendations or prescriptions must be simple, understandable and easy to implement in daily life by most patients.

Quality Assessment For Risk Of Bias Within Studies
There were no intervention trials found related to this topic. Among the 11 reference articles analyzed in this systematic review, 10 were cross-sectional post hoc analyses of cohort studies . One was a retrospective observational cohort specially designed to assess the association between potassium intake and renal outcomes in patients with diabetes . We used the National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort, Cross-sectional Studies, and Case-Control Studies to assess the quality of each study. Studies were graded in 3 broad categories: the definition and representativeness of the studied population, definition and measurement of exposure and outcome, and data analysis. Each category was broken down into subcategories, with 1 point awarded per subcategory if clearly presented in the article. The maximum score was 20 points, and a score 16 was defined as high quality .
Stage 4 Kidney Disease: How Much Potassium Intake A Day
Potassium is one important mineral in our body that can be found in many foods. Just like calcium, potassium level in the blood should keep in normal range. Otherwise, both low and high potassium level can cause health problems. For patients with stage 4 kidney disease, potassium level is usually higher than the normal, so they should know how much potassium intake one daily to improve health condition.
What does potassium do in the body?
As one essential mineral, potassium is responsible for controlling nerve and muscle function, regulating heartbeat, and maintaining the balance of fluid, electrolyte balance and PH level. Nearly all potassium in our body comes from foods what we eat, and normally, it ranges from 3.5 to 5.5 mEq/L.
Why do patients with Stage 4 CKD need to restrict potassium intake?
In general, healthy kidneys can eliminate extra potassium from the body and make it range among the normal values. However, in stage 4, more than 70% of kidney function has lost, so extra potassium is more likely to accumulate in the body. We call this condition hyperkalemia that can cause nausea, irregular heartbeat, weakness and numbness. To reduce high potassium level and avoid these problems, stage 4 kidney disease patients should develop a low-potassium diet.

Leaching Vegetables To Lower Potassium Content
For those people with high blood potassium, leaching is a way to remove some of the potassium from high-potassium vegetables.
Directions for potatoes, sweet potatoes, carrots, beets, and rutabagas:
Peel and cut vegetables into ?-inch thick slices.
Rinse vegetable slices in water for a few seconds.
Soak vegetable slices in water for a minimum of two hours. Use ten times the amount of water to the amount of vegetables.
After soaking, rinse vegetable slices again in water for a few seconds.
Cook vegetable slices with five times the amount of water to the amount of vegetables.
Directions for mushrooms and frozen greens:
Thaw frozen vegetables and drain.
Rinse vegetables in water for a few seconds.
Soak vegetables in water for a minimum of two hours. Use ten times the amount of water to the amount of vegetables.
After soaking, rinse vegetables again in water for a few seconds.
Cook vegetables with five times the amount of water to the amount of vegetables.
Leaching removes only some of the potassium in high-potassium vegetables. It is still important to limit how much and how often you eat these vegetables if you have high blood potassium .
Dietary Potassium Intake And Serum Potassium Concentrations Or Hyperkalemia Rates
With regard to the relation between dietary potassium intake and serum potassium concentrations or hyperkalemia rates, 4 studies reported on this outcome. Studies unanimously reported no association between potassium intake and serum potassium or hyperkalemia rates . Smyth et al. reported a higher OR for hyperkalemia with increased potassium intake however, the association became nonsignificant after adjusting for known risk factors .

What Should I Know About Phosphorus In My Diet If I Follow A Renal Diet
Phosphorus is another mineral that can build up in your blood when your kidneys dont work properly. When this happens, calcium can be pulled from your bones and can collect in your skin or blood vessels. Bone disease can then become a problem, making you more likely to have a bone break.
Tips to limit phosphorus in your diet
Dairy foods are the major source of phosphorus in the diet, so limit milk to 1 cup per day. If you use yogurt or cheese instead of liquid milk, have only one container of yogurt or 1.5 ounces of cheese per day.
Some vegetables also contain phosphorus. Limit these to 1 cup per week:
Certain cereals should be limited to 1 serving per week. These are:
White or Italian bread and low-salt crackers made with white flour have less phosphorus than whole-grain bread and crackers.
Soft drinks contain phosphorus, so only drink clear ones. Dont drink Mountain Dew® , colas, root beers, Dr.Pepper® . Also, avoid Hawaiian Punch®, Fruitworks®, Cool® iced tea, and Aquafina® tangerine pineapple.
Beer also has phosphorus. Avoid all kinds.
A note from Cleveland Clinic
We all need to pay attention to what we eat. If you have kidney disease, following a renal diet gives you more control over how you feel. Work with your providers and dietitian because youre the most important part of your healthcare team.

Kidney Disease And Hyperkalemia
- Under normal circumstances, the kidneys are responsible for excreting 90% of the potassium that is consumed daily, with the remaining 10% excreted by feces.4,9,27,28
- People with chronic kidney disease have a high risk for hyperkalemia, due in part to the effects of kidney dysfunction on potassium homeostasis.20,29
- A recent review reports hyperkalemia frequency as high as 40-50% in people with chronic kidney disease compared to 2-3% in the general population.7,8,16 CKD patients with the highest risk include those with diabetes, cardiovascular disease, advanced CKD, transplant recipients, and patients taking renin-angiotensin aldosterone system inhibitors.16
- An episode of hyperkalemia in patients with CKD increases the odds of mortality within one day of the event.30
- Hyperkalemia is also common in kidney transplant recipients who receive immunosuppressive therapy with calcineurin inhibitors , with a reported incidence of 44% to 73%. The use of ACE inhibitors and angiotensin-receptor blockers to slow the progression of chronic allograft nephropathy increases the risk.31

How Does Ckd Affect Other Nutrients
A person with CKD may be less tolerant of high sodium levels in their body. A high sodium diet can cause a large amount of fluid in the body, which can result in symptoms of swelling or shortness of breath. Doctors typically use drugs called diuretics to treat these symptoms.
People with CKD also tend to retain more hydrogen in their body.
In the body, hydrogen ions act as acids. If the kidneys are not working properly, there will be higher levels of hydrogen ions in the body. Doctors refer to this as metabolic acidosis. Individuals with metabolic acidosis may require bicarbonate supplements.
The inability of the kidneys to filter blood effectively can result in higher levels of phosphate and lower levels of calcium. This imbalance can cause bone weakness and increase the risk of heart disease and stroke.
Mortality Serum Potassium Concentrations And Dietary Potassium Intake
In earlier stages of CKD, higher dietary potassium intake was found to be associated with lower mortality rates . This may have occurred for 2 reasons. First, high-potassium diets are beneficial for CVD, the main cause of mortality in CKD. Second, as demonstrated in this review, in the early stages, higher potassium intake is associated with a lower rate of CKD disease progression, which, in and of itself, may improve mortality rates. In late CKD, none of the results suggest that lower potassium intake is associated with lower mortality risk. Theoretically, given that hyperkalemia rates increase in later stages of CKD and that hyperkalemia is associated with an increase in mortality one could have expected to see higher potassium intake associated with higher mortality, although this was not found in this systematic review.

Potassium And Chronic Kidney Disease
What is potassium and what does it do in the body?
Potassium is a mineral that controls nerve and muscle function. Theheart beats at a normal rhythm because of potassium. Potassium is also necessary formaintaining fluid and electrolyte balance and pH level.
In order for potassium to perform these functions, blood levels must be kept between 3.5 and 5.5 mEq/L. Thekidneys help keep potassium at a normal level.
When is potassium too low or too high?
Potassium comes from the foods we eat. Healthy kidneys remove excess potassium in the urine to help maintain normal levels in the blood.
Because most foods have potassium, low potassium is uncommon in people who eat a healthy diet.
Some of the effects of low potassium include muscle weakness, cramping and fatigue.
When kidneys fail they can no longer remove excess potassium, so the level builds up in the body. High potassium in the blood is called hyperkalemia, which may occur in people with advancedstages of chronic kidney disease . Some of the effects of high potassium are nausea, weakness, numbness and slow pulse.
Processed Foods Are A Hidden Source Of K+
The transition from raw to processed foods began approximately 10,000 years ago with the onset of agriculture. Processing foods has increased the amount of Na+ and, in some cases, has reduced the amount of K+ intake. As previously discussed, inadequate consumption of K+ combined with excessive intake of Na+ is thought to contribute to the pathophysiology of a variety of chronic diseases such as obesity, hypertension, diabetes, kidney stones, and bone disease. As consumers and health agencies have pushed to reduce the amount of Na+ in processed foods, the food industry has begun to use food additives and preservatives, which are hidden sources of K+. These additives can significantly contribute to the total daily K+ content of foods because some preservatives in meat may add 300575 mg of K+ per 100 g of intake . Additionally, there are products used to enhance flavor which are KCl based and include salt substitutes where 20% of salt is replaced by KCl, which adds approximately 12 mmol/d to the usual K+ intake . In many cases, low K+ products may be high in Na+, making it difficult for patients with CKD to simultaneously adhere to low K+ and low Na+ food selections on a chronic basis .

What Should I Know About Sodium And Salt If I Follow A Renal Diet
Sodium is a mineral found in salt . Its widely used to prepare foods.
Salt is one of the most commonly used seasonings. Itll take time for you to get used to reducing the salt in your diet. However, reducing salt/sodium is an important tool in controlling your kidney disease.
Here are some suggestions.
Low Potassium Foods < 100mg
- soy products ½ cup cooked soybeans ~431mg
- dairy-based foods ½ cup pudding ~215mg, 1 cup yogurt 579mg
- potatoes ½ cup mashed ~ 340mg, 1 medium baked ~925mg
Keep in mind this is not an all-inclusive list of high potassium foods. There are many online reference tools to identify if a food is high in potassium or not. The USDA Food Composition Databases and Health Canada are reputable online sites to assist in identifying nutrient data in various foods.
