E70-E90: Metabolic disorders

The category of metabolic disorders, denoted by ICD-10 codes E70-E90, represents a broad group of conditions that affect the body's ability to process the nutrients needed for daily function. These disorders occur due to malfunctioning of specific chemical reactions in the body, often because of enzyme deficiencies or abnormalities. Metabolic disorders can manifest in a variety of symptoms, which can depend on the specific disorder and the metabolic processes it affects. Some common symptoms include fatigue, weight loss or gain, abnormal growth, skin rashes, and cognitive difficulties. These disorders are typically not contagious and usually result from a combination of genetic factors and lifestyle. Disease progression varies, with some disorders causing mild symptoms and others being severe or even life-threatening. All body systems could possibly be affected by these disorders, depending on the specific metabolism problem that is present.
