Familial periodic paralysis is caused by a lack of potassium 

Riyadh:  Howtat Bani Tamim General Hospital (Central Saudi Arabia) has diagnosed and treated a rare disease called Familial periodic paralysis in a male patient in his 20s. It occurs due to mutations in genes that regulate potassium in the blood.

The patient arrived at the hospital on 25 September with weak muscles, lower heart rates, acute kidney injury (AKI), and rhabdomyolysis that caused an inability to move the upper and lower body parts. The patient intakes cortisone for skin illness, expectedly lowering the potassium in the blood.

After examination, he received potassium intravenously and orally and was under observation until he retained his movement. Then, the healthcare providers took him to the outpatient clinic for follow-ups.
