Hello Doctor, My mother is 53 years old , For the past 2 months, she has been experiencing abdominal pain every time she eats, even if it's a very small amount of food. The pain starts soon after eating. She has a medical history of Parkinson's disease, fibromyalgia, recurrent fatty liver, kidney stones, and piles. Additionally, in November, January, and March, she had episodes of infection with vomiting and loose motions. She consulted a doctor each time and was treated with medications and injections, after which she recovered. Could you please advise what the possible causes of her current symptoms could be? Could this be related to her liver, gallbladder, stomach, or any other digestive condition? What investigations would you recommend? Should she consult a gastroenterologist, and does this require urgent evaluation? Also, is there any medication that can provide temporary relief from the pain until she is evaluated by a specialist? If yes, please suggest
