Restless leg syndrome, or RLS, is a condition that causes an intense and irresistible urge to move your legs due to uncomfortable sensations such as tingling, crawling, pulling or creeping. The sensations are usually brought on by lying down or sitting for prolonged periods of time. RLS usually occurs at night and can disrupt sleep, leading to daytime drowsiness. Severe potassium deficiency can contribute to RLS.
Potassium Deficiency and Restless Leg Syndrome
Potassium is an essential mineral that is needed for the proper functioning of nerve and muscle cells in your body. Potassium is also important for skeletal and smooth muscle contraction. Potassium deficiency can cause nerve problems, muscle weakness, muscle spasms and paralysis. Damage to nerves and muscles of your lower feet by potassium deficiency can contribute to RLS. You can obtain potassium from foods and dietary supplements.
Sources of Potassium
Eating a diet rich in potassium can help prevent potassium deficiency. You can obtain potassium from bananas, oranges, tomatoes, kiwi fruit, cantaloupe, milk, meat, fish, peaches, dates, prunes, beans, peas, Brussels sprouts, potatoes, cauliflower, broccoli, spinach, kale, mustard greens and collard greens.
Potassium Supplements
If you have a severe potassium deficiency, the doctor may prescribe potassium supplements. Potassium supplements are available in form of regular tablets, extended-release tablets, effervescent tablets, granules, powder and oral liquid. Take all forms of potassium supplements with a full glass of water or fruit juice. Do not chew or crush extended-release tablets. Dissolve potassium powder, granules and effervescent tablets in cold water and drink immediately. Do not take more supplements than prescribed. Follow your doctor's and pharmacist's directions.
Side Effects of Potassium Supplements.
Potassium supplements should only be taken under the supervision of a doctor due to possible adverse effects. Common side effects include stomach irritation, nausea and diarrhea.
