Tetany can also be brought on by magnesium deficiency or too little potassium. Having too plenty acid (acidosis) or too much alkali (alkalosis) in the physique can also end result in tetany. There are numerous clinical conditions and medicinal drugs that can cause slight to severe electrolyte imbalances.

For instance, hypoparathyroidism is a situation in which the body doesn’t create ample parathyroid hormone. This can lead to dramatically lowered calcium levels, which can set off tetany.
