Why did I gain so much weight after surgery?

The median change in body weight from before surgery to the day after surgery was + 0.7 kg (0.3–1.6), after correction for resected tissue. The lowest and highest values were − 0.7 and + 2.5 kg, respectively.

The stress response to surgery consists of two main components: neuroendocrine–metabolic and inflammatory–immune. After surgery, there is a state of hyper-catabolism, which produces readily useable metabolic energy sources. Cytokine production is related to the degree of surgical tissue injury.
