** Thanks for contacting with your health concern 1. loss of appetite and fatigue are not a disease but symptom of an underlying disease, and without being able to examine you directly I m of the following symptomwise approach: i. If after taking proper rest, diet you are not feeling better, then certain important points that may be missed are: - As history of falling ill is present, thus one has to find out the cause of the fever, and before labeling it as fever, one must look as a compulsory routine for pallor [Hb%], jaundice [S.bilirubin], neck stiffness, Abdomen for liver & spleen [ ultrasound], and auscultate the chest [X- ray] ii. the feeling of warm might mean that fever is still there, check with your primary care physician and ask for: - Hb%, EBC, ESR, Peripheral smear [for MP] - Widal titre - Urine culture, since additional treatment will depend upon the cause of the fever, so evaluation of associated symptoms is a must. 2. to fell better: take soft food like ganji, kheer, soft rice with milk/ ghee/ plain daal, boiled vegetables,, take plenty of fluids every 2-3 hours, take milk with Horlicks/bournvita, for snacks you can take plain idli with butter, bread butter, toast jam, or cornflakes.
