"Hers Disease", also known as glycogen storage disease type VI (GSD VI), is a rare genetic disorder that affects the body's ability to break down glycogen. This condition is caused by a deficiency of the enzyme known as liver phosphorylase. Although Hers Disease is the commonly used term, it can also be referred to by its medical names such as GSD VI, hepatic glycogenosis with normal blood lactate, or glycogen storage disease type VI. Early diagnosis and appropriate management are crucial for individuals with this condition to prevent complications related to hypoglycemia. Treatment often includes a balanced diet, regular meals, and avoiding fasting periods to maintain stable blood sugar levels.
