<s>[INST] For a week now I have had a gnawing, uncomfortable feeling in my stomach, especially after eating small amounts of food. This occurs maybe half hour or so after eating. Its pretty much been constantly there for the whole week. I stayed home after the first day because I thought I had a stomach flu, but it s continued all week. Nighttime is very uncomfortable. I had a meal replacement drink because I was afraid to eat a meal but the pain and fullness feeling still came shortly after. No matter how small amount of food or drink I have, the full feeling and sharp pain still occur. Can you help me? [/INST] Hi Most likely you are suffering from Acid Peptic Disoder. You need to take simple soft diet without spices. Antacid suspension/gel containing oxetacaine 10ml 4 times daily before taking food with Proton-pump inhibitors (PPIs)- omeprazole 20mg, pantoprazole 40mg, rabeprazole 20mg in the morning empty stomach will be helpful. If needed you can take extra dose of Proton-pump inhibitors in the evening empty stomach. Instead of Proton-pump inhibitors, you can take H2 receptor antagonists - renowned brand Ranitidine (common brand name Zantac by Glaxo) 150mg morning and evening empty stomach may be used.
