Hi there ~
I understand you situation and that you and your wife may have problems with conception. I do not believe that the dizziness
is related to the surgery or the medications. It is also probably not the s typhi o or h that is causing her to be this way. I also think that you need to advise your wife to have better hygiene, daily routine and lifestyle. Adequately hydrating yourself will help. I think that you need to visit with a doctor regarding IVF treatment if you want to have kids. It would most likely be successful.
Take care and have a lovely day!
