Hyperthyroidism limb paralysis symptoms?

summary

4% of hyperthyroidism patients had paroxysmal paralysis of limbs or lower limbs, most of them were male hyperthyroidism patients. The mechanism of hyperthyroidism with limb paralysis is not fully understood. Some people think that it is due to the increase of Na + - K + - ATPase activity in hyperthyroidism. The increase of Na + - K + - ATPase activity can lead to the increase of K + in cells and Na + out of cells, resulting in the decrease of blood K +. Lower blood potassium can cause limb paralysis.

Hyperthyroidism limb paralysis symptoms?

Hyperthyroidism patients with limb paralysis often have some inducing factors. Satiety and too much sweet food are common inducing factors. This is due to the decrease of blood potassium due to the entry of potassium into cells in the process of glycogen synthesis. Other inducing factors are fatigue, mental tension and so on. The onset time was mainly at night.

The frequency of attack is not consistent, less a few times a year, more a few times a day. Each attack time has the length to have the short, the elder several days, the short dozens of minutes, generally for 12 hours or so. During the attack, most of the blood potassium decreased, and a few did not. ECG examination can also prove hypokalemia.

Hyperthyroid limbs are usually reversible lesions. After hyperthyroidism, limb paralysis often does not occur. If limb paralysis still occurs frequently after hyperthyroidism is cured, it suggests that hyperthyroidism is not necessarily the cause of limb paralysis. Familial periodic quadriplegia is common and can coexist with hyperthyroidism. Therefore, after the control of hyperthyroidism, limb paralysis can not be stopped, and the possibility of familial periodic limb paralysis should be excluded.

matters needing attention

When patients with hyperthyroidism are treated with subtotal thyroidectomy, the preoperative preparation should be sufficient, especially when propranolol is used for preoperative preparation, the dosage should be sufficient, the time should be at least one week, and the postoperative medication should continue for one week. The operation should be gentle, and the appropriate amount of glucocorticoid can be supplemented after the operation.
