Infection in the body can be the cause of weight loss if they are sick enough. After it is treated, if the weigh loss continues, you need to move forward with imaging. Radiographs and ultrasound, basically you are looking for any signs of cancer or internal organ disease that could also cause weight loss. If you are worried about this things, you do not need to wait until treatment for infection is over, you can discuss getting those diagnostics done with your veterinarian. I hope this is helpful and please feel free to post any additional questions.
