Carbohydrate metabolism disorders are conditions that affect how the body processes carbohydrates, which are essential for energy. These disorders can lead to abnormal levels of sugars, such as glucose, in the blood, resulting in symptoms like fatigue, weakness, and increased thirst. Common examples include diabetes mellitus and galactosemia. These disorders can arise from genetic factors, enzyme deficiencies, or hormonal imbalances. Proper diagnosis often involves blood tests to measure sugar levels and other metabolic markers. Treatment may include dietary changes, medications, or insulin therapy to help manage symptoms and maintain normal carbohydrate metabolism.
