# Do You Have the Chvostek Sign? It Could Mean Something Life-Changing! Have you ever heard of the Chvostek sign? This subtle neurological reflex, named after Danish neurologist Johan Hence Chvostek, is far more than a medical footnote—it could be an early warning sign of a serious underlying condition that affects your health and quality of life. If you’ve ever felt a brief facial twitch or stiffness upon tapping your face, you might have experienced it firsthand. Understanding the Chvostek sign could not only reveal hidden health risks but also be life-changing. ## What Is the Chvostek Sign? The Chvostek sign is a neurological reflex where gently tapping the facial nerve (typically the mandibular branch of the trigeminal nerve) triggers an involuntary twitching or contraction of the facial muscles on the opposite side of the tapping. This reaction occurs when brainstem pathways controlling facial muscle tone are disrupted—commonly a signal of hypocalcemia, or low blood calcium levels, but it can also point to neurological conditions or metabolic imbalances.
