2. Loss of Appetite
It is also common for patients suffering from bowel obstruction to lose their appetite. Because of this, a lot of them end up anorexic. However, the loss of appetite is also seen in other conditions. In fact, appetite loss is common in infections, as it is thought to be part of the acute phase response that is triggered by the various components of the bacteria causing the infection.
Loss of appetite can also happen in patients suffering from anxiety, pneumonia, cancer, appendicitis, kidney disease, dehydration, heart failure, fever, dementia, hypothyroidism, and some metabolic disorders. For patients with bowel obstruction, loss of appetite could occur as a result of increased intra-abdominal pressure, cramps, and abdominal pain.
