Typically, the potassium level becomes low because too much is lost from the digestive tract due to vomiting, diarrhea, or excessive laxative use. Sometimes too much potassium is excreted in urine, usually because of drugs that cause the kidneys to excrete excess sodium, water, and potassium (diuretics).
Potassium is a mineral that every cell in your body needs. It helps just about your whole body work right, including your brain, nerves, kidneys, heart, and other muscles. You might be surprised by everything it does for you.
Hypokalemia is often caused by an excessive loss of potassium in your digestive tract due to vomiting, diarrhea or laxative use. Other causes include certain medications and some adrenal and genetic conditions.
Just as potassium levels in the body can get too high, they can also drop too low, which doctors refer to as hypokalemia. Hypokalemia is typically due to another underlying medical illness that a doctor must diagnose. Possible causes of hypokalemia include : kidney disease.
What cancers cause low potassium? Anyone with cancer has a high risk for electrolyte imbalance, which include hypokalemia. Patients with breast, stomach, kidney, pancreatic, thyroid, prostate cancer, and so on can have low potassium as part of the condition's complications and the side effects of the treatment.
Hypokalemia is common in the setting of cirrhosis: multiple potassium wasting mechanisms both inherent to the disease and resulting from its management make these patients particularly susceptible to potassium depletion even in the setting of normokalemia.
In hypokalemia, the level of potassium in blood is too low. 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.
If you are taking oral supplements for hypokalemia, it may take several days to weeks to get your potassium level back up. In certain situations, you may need to stay on oral potassium pills long term to counterbalance your body's loss of potassium.
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.
It is the job of your kidneys to keep the right amount of potassium in your body. If there is too much, healthy kidneys will filter out the extra potassium, and remove it from your body through urine. However, when kidneys do not work well, they may not be able to remove enough potassium.
Low serum potassium level is associated with nonalcoholic fatty liver disease and its related metabolic disorders.
Potassium plays an important role in regulating the contractions of all muscles, including the heart muscle. Very low levels of potassium in the body can lead to irregular heart rhythms, including sinus bradycardia, ventricular tachycardia, and ventricular fibrillation.
A small drop in potassium level often does not cause symptoms, which may be mild, and may include: Constipation. Feeling of skipped heart beats or palpitations. Fatigue.
Signs & Symptoms
However, symptoms of hypokalemia may include attacks of severe muscle weakness, eventually leading to paralysis and possibly respiratory failure. Muscular malfunction may result in paralysis of the bowel, low blood pressure, muscle twitches and mineral deficiencies (tetany).
Treatment by potassium replacement intravenously is effective, and recovery occurs within 24 hours.
An easy way to boost your potassium intake is by eating five portions of fruit and vegetables a day. Other foods like pulses, fish, nuts, seeds and milk are also high in potassium and low in salt, so can help benefit your heart.”
Potassium Chloride (Klor-Con M, K-Tab, Klor-Con, Micro-K) is a potassium supplement used to prevent and to treat low potassium. Potassium is important for the heart, muscles, and nerves. Too much or too little potassium in the body can cause serious problems. It is more popular than comparable drugs.
A diet high in potassium. Eating too much food that is high in potassium can also cause hyperkalemia, especially in people with advanced kidney disease. Foods such as cantaloupe, honeydew melon, orange juice, and bananas are high in potassium. Drugs that prevent the kidneys from losing enough potassium.
This disorder is most commonly caused by cancer or parathyroid disease. Hypercalcemia resulting from cancer is particularly common in conjunction with breast cancer, lung cancer or multiple myeloma and often results from the destruction of bone due to bone metastases.
Common symptoms of hypokalemia and/or potassium deficiency are reviewed as well, such as general and unspecific symptoms (e.g. tiredness, lack of concentration, lack of appetite and vomiting), and symptoms from the heart, kidneys and skeletal muscle.
Hyperaldosteronism can be caused by a tumor in the adrenal gland or may be a response to some diseases. High aldosterone levels can cause high blood pressure and low potassium levels.
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.
