Hi.
Thanks for your query and an elucidate history.
Since your Mother has been diagnosed as antral erosion and
duodenitis and has already taken treatment and if not getting relief I would advise you the following:::
Zantac 12 hourly.
Pepcid every 3 to 4 hours when on empty stomach.
Add
Domperidone or such motility regulators.
Soft bland diet.
No aerated colas / soda/ drinks.
Early dinner. No late nights.
Treatment for anxiety (as prescribed / needs a prescription by your Doctor)
Lying in a reclining position
Walk around after dinner.
Think of the factors which increased the present problem, GERD, anxiety and try to avoid.
If no relief, get Upper GI endoscopy done and get prescription for added Medicines.
Also to get
ultrasonography and CT scan of the upper abdomen to see thre is no
gastrinoma or
pancreatic tumor that is causing these problems. in spite of proper treatment.
This helps all my patients and should help you hopefully.
