Malabsorption refers to the body's inability to properly absorb nutrients from the diet, which can lead to several complications in sick patients. One significant consequence is dehydration. When nutrients, including fluids, are not adequately absorbed in the gastrointestinal tract, the body may struggle to retain necessary hydration levels. This may also occur alongside gastrointestinal symptoms such as diarrhea, which can further exacerbate fluid loss and lead to dehydration.

In contrast, the other options do not align with the typical outcomes associated with malabsorption. Increased appetite is generally not a direct result of malabsorption, as the body may not signal hunger effectively if nutrient levels are insufficient. Better metabolism is unlikely because malabsorption often results in a decreased ability to utilize nutrients effectively, which can lead to metabolic issues rather than improvements. Lastly, weight gain is generally not expected, as malabsorption typically leads to weight loss due to the body being unable to absorb and utilize nutrients properly. Thus, dehydration stands out as a key consequence of malabsorption in sick patients.
