I had old and stale protein drink about 5 days back. Soon after that has fever, head ache, loose motion( only twice). Till today morning had fever. Doctor says it is viral fever, but I still doubt about the protein drink. Will it have side effect and what to take?
Hello, Welcome to Chat Doctor, Most of this protein powder will have milk or milk byproducts, like whey protein. These will develop an off flavor with time, more so if they are exposed to air. The other ingredients, like flavorings will deteriorate as well. The symptoms may be due to this, because the milk products can upset your gastrointestinal system and may produce symptoms like loose motion. The secondary bacterial infection can lead to constitutional symptoms like fever and headache. So avoid taking this protein powder, take appropriate treatment for the present symptoms. Oral re HY Chat Doctor. Thank you.
