Cramps falling

Hypokalaemia occurs when the plasma-potassium level falls below 3.0 mmol/L Hypokalaemia may occur following loop or thiazide diuretic therapy. Patients at risk of developing hypokalaemia are often prescribed potassium supplements to counteract the potassium loss caused by the diuretic therapy. Symptoms of hypokalaemia include muscle weakness and cramps. Severe cases may lead to muscle paralysis and respiratory failure. 

Calcium deficiency in blood plasma causes muscle cramps, twitching and eventually convulsions. If the blood calcium level falls, calcium is leached from the bones, causing osteomalacia. A group of cardioactive drugs known as the Ca antagonists block influx of Ca2+ into infarcted, dying heart muscle cells following myocardial infarction.55,80...

Buffers in Blood Your blood is a slightly alkaline solution with a pH of approximately 7.4. To be healthy, that pH must be maintained within narrow limits. A condition called acidosis occurs if the pH falls more than 0.3 units below 7.4. An equally serious condition called alkalosis exists if the pH rises 0.3 units. You may have experienced a mild case of acidosis if you have overexerted and developed a cramp in your leg. Cramping results from the formation of lactic acid in muscle tissue. 

Various organo-phosphorus compounds are used two of the commonest are demeton-S-methyl and chlorpyrifos. Poisoning causes headaches, nausea and blurred vision. Further symptoms include muscle twitching, cramps in the belly muscles, severe sweating and respiratory difficulties. Extreme exposure may lead to death. All these effects are due to interference with a chemical enzyme called cholinesterase which is concerned with the passage of nerve impulses. The level of this enzyme in the worker s blood can be measured and if it falls below a certain value the worker must be removed from contact with the chemical until his blood returns to normal. The appropriate protective clothing must be worn at all times when working with these materials.
