My mother is suffering from severe gastric issues and constipation. Please advice.

Hi doctor,

My mother is 66 years old. She is suffering from severe gastric trouble. She has had her gall bladder removed 20 years back and since then takes a lot of precautions while eating. Since last week she is having a lot of gastric issues and constipation. She had severe pain last week and has been taking Pantoprazole, Cyclopam (Paracetamol, Dicyclomine), Norflox TZ (Norfloxacin + Tinidazole) for the past one week with very little relief. She again had severe stomach pain in the middle of the night for two consecutive nights. The pain is unbearable, and she cries out of pain for about one hour and even vomited out fluid one night. It only got better when we gave her Digene (Antacid) and a hot water bottle to settle the spasms on both nights. She is now scared to sleep tonight, dreading another bout of pain. She has been eating very little food for the past week and is also constipated.

Please advise urgently.
