"Taruis Disease" is a rare genetic disorder that affects the way the body metabolizes glycogen, resulting in a buildup of this complex sugar molecule in the muscles and liver. Although this condition is commonly referred to as "Taruis Disease", it is also known by other names such as "Glycogen Storage Disease Type VII" or "McArdle Disease". All these terms describe the same condition, which is characterized by muscle cramps, fatigue, weakness, and an inability to generate energy during physical exertion. Recognizing these synonyms is crucial for accurate identification and proper medical management of individuals with this metabolic disorder.
