muscle cramps. confusion. constipation. an abnormal heart rhythm (arrhythmia) – skipped heartbeats or an irregular heartbeat.
Over time, low levels of potassium in your body can cause effects such as abnormal heart rhythms, muscle weakness and even paralysis.
Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L ) can be life-threatening and requires urgent medical attention.
Low potassium (hypokalemia) has many causes. The most common cause is excessive potassium loss in urine due to prescription medications that increase urination. Also known as water pills or diuretics, these types of medications are often prescribed for people who have high blood pressure or heart disease.
A person cannot live without potassium. Potassium helps carry electrical signals to cells in your body and is essential to ensure our nerve and muscles cells, particularly heart muscle cells, are functioning properly.
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.
Treatment by potassium replacement intravenously is effective, and recovery occurs within 24 hours.
Common causes of low blood potassium include: Medicines, such as diuretics (water pills), certain antibiotics (amphotericin B, chloroquine at toxic levels) Diarrhea or vomiting. Eating disorders (such as bulimia)
Low potassium levels can slow your heartbeat, too, which can result in fainting.
It is often due to a paraneoplastic syndrome, related to several kinds of tumors. It is most frequently reported in patients with small-cell lung cancer, but it is also described in patients with non-small-cell lung cancer, head and neck cancer, and, rarely, other malignancies.
Low levels of potassium have been linked to high blood pressure, heart disease, and stroke in people.
Severe hypokalemia can lead to abolition of all muscular contractions and mimic brain death.
Potassium is a mineral and an electrolyte that the body requires to support key processes. It is one of the seven essential macrominerals and plays a role in the function of the kidneys. Having too much or too little potassium can result in complications that affect the kidneys.
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.
We suggest criteria for hospitalization, which include severe hyperkalemia (≥8.0 mmol/L, with changes other than peaked T waves on the electrocardiogram), acute worsening of renal function, and supervening medical problems.

Levels higher than 7 mEq/L can lead to significant hemodynamic and neurologic consequences; levels exceeding 8.5 mEq/L can cause respiratory paralysis or cardiac arrest and can quickly be fatal.
5.5-6.0 mEq/L - Mild. 6.1-7.0 mEq/L - Moderate. 7.0 mEq/L and greater - Severe.
Low levels of potassium have been linked to high blood pressure, heart disease, and stroke in people.
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.
