Thank yo for the query.
This medicines decreasing stomach acid production, allow bacteria to reach intestines. This can cause some gastrointestinal infection
and give diarrhea
You may try to get probiotic
and see if this will help.
If not, you may need a surgery to fix hiatal hernia. I suggest you to vonsult a surgeon. Laparoscopic surgery
can be very helpful and set you free from all symptoms so you want need mentioned medicines anymore.
Hope this will help.
