- A cramp is a sudden, involuntary muscle contraction or over-shortening; while generally temporary and non-damaging, they can cause significant pain, and a paralysis-like immobility of the affected muscle. Onset is usually sudden, and it resolves on its own over a period of several seconds, minutes or hours. Cramps may occur in a skeletal muscle or smooth muscle. Skeletal muscle cramps may be caused by muscle fatigue or a lack of electrolytes such as low sodium, low potassium or low magnesium. Cramps of smooth muscle may be due to menstruation or gastroenteritis.

- QUOTE: Low fluid levels in the body can result in calcium and phosphorus imbalances that can cause leg cramps. This can occur from taking diuretics, excessive perspiration, vomiting, and diarrhea. Water is important for transporting vitamins, minerals, and other substances throughout the body. Hydration is not the same when drinking caffeine or alcohol, since they are diuretics and end up dehydrating a person even further. … Calcium deficiency is also responsible for muscle tremors and twitching at night and may lead to night-time leg cramps. However, milk and other dairy products do not make effective calcium replacement sources because of their phosphorus levels. A non-phosphorus containing calcium supplement is possibly the best alternative. Another mineral easily depleted is potassium, which is the most important mineral regarding muscle activity, serving as an electrolyte in the body and helping to balance body fluids. It also plays an essential role in muscle control and acts as a co-factor in muscle building.
