Too much potassium in your blood can be dangerous and can cause an irregular heartbeat or a heart attack. At first, many people with high potassium have few or no symptoms. Early symptoms can include muscles that are weak numb or in pain, tingling, shortness of breath, nausea, or other unusual feelings.
Potassium helps keep your heart beating at the right pace. It does this by helping to control the electrical signals of the myocardium -- the middle layer of your heart muscle. When your potassium level is too high, it can lead to an irregular heartbeat.
Having too much potassium in your blood can be dangerous. Potassium affects the way your heart's 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.
A large drop in potassium level may lead to abnormal heart rhythms, especially in people with heart disease. This can cause you to feel lightheaded or faint. A very low potassium level can even cause your heart to stop.
A typical potassium level for adults is between 3.5 and 5.0 millimoles per liter (mmol/L). Hyperkalemia occurs when potassium levels go above 5.5 mmol/L. A potassium level above 6.5 mmol/L can cause heart problems that require immediate medical attention.
If hyperkalemia comes on suddenly and you have very high levels of potassium, you may feel heart palpitations, shortness of breath, chest pain, nausea, or vomiting. Sudden or severe hyperkalemia is a life-threatening condition. It requires immediate medical care.
Excessive water consumption may lead to depletion of potassium, which is an essential nutrient. This may cause symptoms like leg pain, irritation, chest pain, et al.
A large drop in potassium level may lead to abnormal heart rhythms, especially in people with heart disease. This can cause you to feel lightheaded or faint. A very low potassium level can even cause your heart to stop.
Can I take the test at home? You can take a potassium test at home, either with a blood or urine sample. If using a 24-hour urine test, you will need to collect your urine wherever you are during the day. For blood tests, you often need to visit a local laboratory to have your sample collected.

Magnesium has a direct effect on the balance of other electrolytes, including sodium, calcium and potassium. Hypomagnesemia often happens alongside hypocalcemia (low blood calcium levels) and hypokalemia (low blood potassium levels).
Normal body levels of potassium are important for muscle function. Potassium relaxes the walls of the blood vessels, lowering blood pressure and protecting against muscle cramping.
Magnesium and potassium are often prescribed together for treating certain diseases and illnesses, such as heart failure, as they both provide cardiovascular benefits. Both minerals also work synergistically together to improve mood and reduce the risk of mental health conditions.
Low blood potassium typically occurs because of an excessive loss of potassium in your digestive tract. This may be due to frequent vomiting, diarrhea or laxative use. Other causes of hypokalemia include: Eating disorders, such as bulimia nervosa.
The Link Between Magnesium, Potassium, and the Heart
This is the critical link between these two ions and the heart — magnesium is critical to transporting potassium into the heart cells and optimizing heart health.
A low potassium level has many causes but usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics. A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop.
Very low levels of potassium in the body can lead to irregular heart rhythms, including sinus bradycardia, ventricular tachycardia, and ventricular fibrillation. If a person does not receive treatment, these conditions can be life-threatening. Doctors can detect irregular heart rhythms using an electrocardiogram (EKG).
cup of black coffee has 116 mg of potassium3. This is considered a low potassium food. However, many people drink more than one cup of coffee each day. Three to four cups of coffee a day is considered high in potassium and could raise your potassium levels.
Treatment by potassium replacement intravenously is effective, and recovery occurs within 24 hours.
