Hello and welcome to HCM,
There is blood loss in road side accidents (RTA).
This blood loss may be external or internal.
Bruising indicates internal blood loss.
It leads to fall in hemoglobin
The fall in hemoglobin levels leads to symptoms of tiredness
, weakness, palpitations, etc.
You need to get complete hemogram done.
Any abnormality in level of hemoglobin, red blood cell counts, hematocrit
, RBC indices - MCV, MCH, MCHC can be detected.
In case of anemia
(low hemoglobin) appropriate treatment can be given.
Thanks and take care
Dr Shailja P Wahal
