The question of whether or not it is good for a person with a fever to have exhaustion cannot be generalized. Usually, for patients with digestive infections, the presence of gas at this time is a sign that the condition is improving. However, in patients with non-digestive tract infections, excessive exhaustion is not good for the condition. For patients with gastrointestinal infections, such as acute gastrointestinal infections, peritonitis, appendicitis or intestinal obstruction, if the condition improves after using certain antibiotics and antimicrobials, the exhaustion will occur on top of the original non-exhaustion. For example, patients with intestinal obstruction may experience exhaustion after the application of anti-inflammatory drugs, which proves that the flora in the intestine is returning to normal and is a sign of improvement. However, for patients with non-digestive system infections, upper respiratory tract infections and urinary tract infections, frequent outgassing is evidence of imbalance in gas production in the gastrointestinal tract, and at this time, there may be a double infection leading to gastrointestinal distention, which is not a good time to have excessive outgassing.
