Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.

 

Islam is built on accommodating people’s issues especially when it comes to medical problems.

 

First, you need to check with a doctor to make sure if there are any medications that you can take and it will help you control this issue.

 

If that is not a possibility, you only need to make wudu’ for each Salat and pray. Even if you pass gas during Salah, you can continue insha Allah and finish your salat.

 

Almighty Allah knows best.
