Hi, thanks for reaching out.
I understand your concern.
Bruises in little ones are usually common. There may be various causes for the bruises depending on how frequent they are, location, associating signs, color of the bruise, etc.
Differentials may be
injury, bleeding disorders ( if associated with a nosebleed),
thrombocytopenia, HSP ( associated with lower
abdominal pain, bruise like patches over the arms, legs, buttocks), hemophilia(factor deficiency), ITP, also a few drugs like antibiotics,
aspirin,
seizure medication may cause abnormal bruising.
For frequent bruising or abnormal bruising associated with signs it is best to get blood diagnostic tests done.
Hope this answers your queries.
Take care.
Regards,
Dr Vignan Rachabattuni
