Hi,
Welcome to the ehealthforum and I am glad to help you out. To be honest, thereâs no such known illness in which thereâre such episodes of fever/rise of temperature during eating which come in cycles. However, it makes sense to get yourself evaluated by a physician. A thyroid profile should be done as increase in metabolism rate due to hyperthyroidism can result in increase in the body temperature. An x-ray of the chest and ultrasound along with liver and kidney function tests should also be done to sure everythingâs fine. I sincerely hope that helps. Take care.
