An effect of malnutrition on respiratory function is

Malnutrition has extremely adverse effects on respiratory function, decreasing both surfactant production and vital capacity. Excessive lipid intake can impair capillary gas exchange in the lungs, although this is not usually sufficient to produce an increase in PaCO2 or decrease in PaO2; this results in decreased respiratory function.
