Weight Loss and Nutritional Assessment

  • Martin H. Floch
Part of the Topics in Gastroenterology book series (TGEN)


Weight loss occurs because of inadequate caloric intake. [Optimal body weights are described in Chapter 2 (Table 2-6).] Weight loss is a state of malnutrition. However, malnutrition also includes obesity and disorders that result in overnutrition as well as undernutrition. Furthermore, malnutrition includes selective deficiencies in proteins, vitamins, and minerals such as described in Chapters 2 and 3. A simple lack of food supply remains the greatest cause of decreased caloric intake in the world. Consequently, starvation, kwashiorkor, and marasmus are the most common diseases resulting from inadequate food supply and are seen frequently in underdeveloped societies. Obviously, these are due to economic and sociologic factors rather than body disorders or digestive diseases.
