• To assess the risk for micronutrient deficiencies as evident from the pattern of food restriction.
• To assess, if the patient is underweight, for complications of protein/energy malnutrition including cardiac complications and the impact on bone density.
• To monitor, if required, nutritional rehabilitation in the underweight patient by admission with daily blood tests to rule out refeeding syndrome.
