Izomrángás

Izomrángás, also known as muscular twitching or fasciculation, refers to the involuntary contraction of a small group of muscle fibers. This phenomenon is often visible on the skin's surface as a brief, flickering movement. Izomrángás can occur in any muscle group but is commonly observed in the eyelids, arms, and legs.

Several factors can trigger izomrángás. Stress, fatigue, and excessive caffeine intake are frequently cited causes. Dehydration and certain electrolyte imbalances, such as low magnesium or potassium levels, can also contribute. In some cases, izomrángás might be a side effect of specific medications.

While usually benign and temporary, persistent or widespread izomrángás can sometimes indicate an underlying neurological condition. Conditions like amyotrophic lateral sclerosis (ALS), spinal muscular atrophy, or peripheral nerve damage can manifest with fasciculations. A medical professional can diagnose the cause of izomrángás through a physical examination, medical history review, and potentially further diagnostic tests like electromyography (EMG). Treatment typically involves addressing the underlying cause, such as managing stress, adjusting diet, or treating the specific medical condition.
