Decreased appetite and unintentional weight loss are nonspecific symptoms that can accompany many different types of illness. Likewise, fever may accompany inflammation in the body due to infection or other causes. Because these symptoms are not specific to one medical condition, it is important to take note of all your symptoms and discuss them with your doctor to determine the cause.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
