<s>[INST] Hi, Doctor, hope everything is fit n fine at your end by the Grace of Almighty Allah.I am taking this opportunity to discuss the condition of my father. He is 73. I am also sending you his medical reports by email separately. As per the medical reports, everything seems ok except Thyroid. My father suffers from extreme abdominal pain, we have to rush for the emergency treatment and every time there are Injections like. Flagyl, Lycofil etc and pain killers. He gets the relief but the same appears again after some days. I do not have the Ultra Sound image at the moment but that was also fine. He cannot eat more than 2 to 3 spoons/bites. Most of the time he vomits out everything right after eating. Some times he says, he is hungry but cannot eat.Doctor, pls advise as per your best judgment after checking the medical reports and the conditions described above.Awaiting your reply anxiously. Thanks & best regardsSameer Hafeezemail :  YYYY@YYYY [/INST] Hello, HafeezThanks for using Chat Doctor. You father seems to be suffering from Some pathology in side his gastrointestinal tract. It may not be visible in ultrasound. These type of cases have to go through endoscopic examination. This pathology can be in the throat, esophagus, stomach or duodenum. You have not given reports of liver function test, that also needs to checked. Now I suggest you to see his treating doctor and request him for the same, you can also give reference of our conversation as well.Meanwhile try to give him nourishment in the way it is possible, so that his general condition improves. Wishing you good luck and speedy recovery of your father. </s>
