11. Weight loss
Alterations in the intestinal wall caused by the disease can cause a failure in the ability of the intestines to absorb nutrients, which in turn causes weight loss. Besides, when an inflammatory process takes place, the energy demand increases. The energy comes from the degradation of nutrients present in the foods that are usually consumed. Therefore, intestinal inflammation leads to the consumption of a large amount of energy or nutrients, which translates into a more accelerated metabolic process and weight loss.
