Hi, Thanks for the query. I understand your concern and no much to worry about this. This could be a viral fever
associated with gastritis
. Viral fever could last for 3-5 days and is associated with loss of appetite. It may be a coincidence of contracting viral infection and with the meal. Stomach ache, nausea
and loss of appetite could be treated with medicines. Please get back for further queries. Thank you for approaching Healthcare magic team.
