What causes increased heart rate and low hemoglobin level in a 3 year old?
Patient: Hi, I have a 3.5 month old baby boy his heart rate is 150 we took x ray of baby's chest is normal, again blood test for knowing any infection, thyroid or any pottasium , calcium are in high or low, finally our baby has only 8.9gm hemaglobin, and doctor gave a iron syrup.We are worried too much Doctor: HI low hemoglobin results from decrease intake of foods containing iron(green leaf vegetables,carrot, fruits, dates etc) or due to loss of blood or eating pica(sand,paint etc). This results in decreased oxygen to all body parts-heart resulting in increased heart rate.Hope this answers your query and ready to help you further.
