Metabolic Disease (Metabolic Disorder)

A metabolic disease (metabolic disorder) is a medical condition that disrupts the body’s normal metabolism. Metabolism refers to all the chemical processes that convert food into energy and essential substances needed for growth, repair, and normal body functions. Metabolic diseases can be inherited (genetic) or acquired during life. They often result from problems with hormones, enzymes, organs, or biochemical pathways that regulate the body’s use of carbohydrates, fats, proteins, vitamins, or minerals.

Common symptoms may include fatigue, abnormal weight changes, growth problems, organ dysfunction, neurological symptoms, or abnormal blood sugar levels.

Ten Important Metabolic Diseases

  • Type 2 DiabetesType 2 Diabetes Mellitus
    • Characterized by insulin resistance and high blood sugar levels.
    • The most common metabolic disorder worldwide.
  • Type 1 Diabetes
    • An autoimmune disease in which the pancreas produces little or no insulin.
  • Obesity
    • A chronic condition involving excessive body fat and altered energy metabolism.
  • Metabolic Syndrome
    • A cluster of conditions including obesity, hypertension, high blood sugar, and abnormal cholesterol levels.
  • Familial Hypercholesterolemia
    • A genetic disorder causing very high LDL (“bad”) cholesterol levels.
  • Gout
    • Caused by elevated uric acid levels, leading to crystal deposits in joints.
  • Phenylketonuria (PKU)
    • A genetic disorder in which the body cannot properly break down the amino acid phenylalanine.
  • Gaucher Disease
    • A rare genetic disorder caused by deficiency of an enzyme involved in lipid metabolism.
  • Wilson’s Disease
    • A genetic disorder that causes excessive accumulation of copper in the body.
  • Hemochromatosis
    • A disorder leading to excessive absorption and storage of iron.

Metabolic diseases affect the body’s ability to process and use nutrients and energy correctly. They range from very common conditions such as Type 2 Diabetes and Obesity to rare inherited disorders such as Phenylketonuria (PKU) and Gaucher Disease. Early diagnosis and treatment are often important to prevent long-term complications.
