Hi,
Your history is suggestive of an intestinal infection of sub-acute nature that is causing all the changes like loss of appetite and gurgling sounds in abdomen, more so on eating.
I would advise you the following in such a situation:
Get the stool tests done, if there is any infection a course of an antibiotic and
metronidazole can help you to get have restored the normalcy.
Also take pre and probiotics available in Pharmacy nearby and bananas with curds.
Use boiled for 20 minutes and cooled water for drinking.
Eat only home-made fresh foods.
If these things do not help then you may need additional tests of blood,
ultrasonography to find out the cause and get treated accordingly.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, General Surgeon
