72-Year-Old Mother with IBS: Seeking Relief from Constipation

My father is 88 years old...he has IBS since last 8 years. Last 6 months, along with IBS he has excessive gas issue which is leading to abdominal cramp, which is further increased drastically in last 2 weeks..I have consulted with gastro specialist 2 months back as well as ayurvedic doctor one week back....nothing abnormal found in investigation..As per them , due to age he has bowel movement problem. They has given some medication, which my father is regularly taking without no improvement. Pls also note that , my father's gall bladder also removed 12 years back..He is also on very restricted diet as per advice of doctor. Can you pls suggest for any improvement in the situation?

Please suggest some remedies for IBS, constipation and gastric issues.
