Yes the specialist checked my saikang and later, he told me my haemoglobin went down to 8.7 from 9.3
And he let me choose between endo or colono which he added the latter is not urgent unless needed
Doing the scope tmr morning
U are losing blood as your reading has degraded from 9.3 to 8.7 over a week ?
You had symptom of a very fast heartbeat that can be triggered by low hb.
Hope your hb stays above 8 (may require blood transfusion if lower) and all the best for your endoscopy.
