Introduction: Hypokalemic periodic paralysis (HPP) is a rare disease. This disease is associated with skeletal muscle, characterized by intermittent episodes of acute flaccid paralysis accompanied by hypokalemia. Hypokalemia paralysis can be primary or secondary. Hypertension is a common health problem and affects about 10% of the population. Although most of the etiologies of HHP are primary, several sporadic cases of different etiologies have been reported, including rare causes such as primary hyperaldosteronism (PA). Primary hyperaldosteronism is the most common form of endocrine hypertension.
Case Report: A case of a 22-year-old male is presented here. The patient presented with weakness in all extremities since the morning after waking up and had the same history before. Laboratory evaluation revealed a markedly low potassium level. There are no other complaints felt by the patient and he was discharged with no neurologic deficits. Although rare, Periodic Paralysis must be differentiated from other causes of weakness and paralysis so that the proper treatment can be initiated quickly.
Discussion: From the clinical symptoms, the results of the patient's physical and laboratory examination, the diagnosis of hypokalemic periodic paralysis must be considered because episodic attacks of weakness occur in the presence of trigger factors and the laboratory examination reveals hypokalemia. Diagnosis of HPP was based on low blood potassium levels (less than 3.5 mmol / L) at the time of the attack, the patient had flaccid paralysis with other tests within normal limits, so this patient was suspected of having hypokalemic periodic paralysis accompanied by hypertension.
Conclusion: The goal of HPP management is to relieve the symptoms of an acute attack, manage complications, and prevent future attacks. The aetiology underlying the occurrence of hypokalemia should also be further explored, especially to rule out secondary causes in patients.
