No, it doesn’t.

If we don’t say bismillah before doing wudhu does it invalidate our wudhu?

I am 24 years old. I was a chain smoker and  from the last 4 years i left smoking . and from the day I left smoking my stomach is disturbed. I did not remain in wudhumore than 2 or 4 minutes my stomach start making gases in every ten minutes .and in Ramadhan it is difficult for me to do wudhu again and again. In Salah I also find difficult…please elaborate me briefly ?
