Hi Nur,
I had my spleen taken out at the age of 17. It was very enlarged and the doctors were afraid that it could get accidently ruptured by falling down badly or while playing soccer, etc. My Hb prior to removal of spleen used to hover around 7.0-7.5 gms/dl. Post removal, it went up to 9.0-9.5 gms. Now, it remains around 8.5-9.0 gms. These comparisons are all with transfusions, and over same time gaps.
I had taken the Pneumo.... vaccine before the surgery. Post surgery, I have been taking 125mg of oral pennicillin on a daily basis, for the last 19 yrs. I have not really been plagued by any more infections after the splenectomy, than before. However, I did feel very energised post-splenectomy, as if a big weight had been rolled off me, which it had literally too (the spleen weighed some 2.4 kgs, if i remember correctly!!!).
Hope that is useful.
