I have a daughter (5-years-old) who has been bruising very easily then started getting petechiae all over her body now in her mouth, she has no appetite (she feels full all the time) and is tired, but has been acting like her normal self, could this be a dietary issue?
Hello, That is a very good question. Anytime we see petechial on a patient, it can mean internal bleeding. The flat dots that you see are broken capillaries that can be due to straining. Now you said her appetite is decreased. Is she sick in any other way? Does she have a cough or fever? Petechial inside the mouth can be from prolonged coughing or vomiting. Does she take any daily medications? There are a handful of medications that can lead to petechial and skin bruising. Lastly, when a child comes into the office with skin bruising and petechial, I would typically do a blood test to check for a fungal, viral or bacterial infections. Those include Cytomegalovirus (CMV) infection, Meningococci, Mononucleosis, Rocky Mountain spotted fever, Scarlet fever and of course Sepsis.  A bunch of those can be ruled out upon physical examination, but blood testing would be best. I hope this helps and if you have any other questions, let me know.
