E70-E90: Metabolic disorders

E74: Other disorders of carbohydrate metabolism

Other disorders of carbohydrate metabolism, as classified under the E74 category, represent a group of conditions that affect the body's capacity to manage blood sugar levels properly. These conditions occur when enzymes responsible for breaking down these sugars in the blood are defective or absent. As a result, cells do not get enough energy, and sugar buildup can damage tissues and organs, particularly the liver and muscles. Common symptoms may include low energy levels, weight loss, sweating, nervousness, and a fast heart rate. The diseases are mainly genetic and thus cannot be transmitted from person to person through touch or air. Progression may lead to serious health problems, including heart disease, stroke, kidney disease, eye problems, and nerve damage. The exact manifestations and health impact will vary depending on the specific disorder within this category, the individual's other health conditions, and the level of control over their blood sugar levels.
