Hello Doctor, I am a 27 year-old male with weight 36 kg and height 5'7". I have the following symptoms: Severe constipation (no motion for 7–8 days sometimes) Bloating and tightness in stomach after eating Loss of appetite, weight loss Bad breath Chest discomfort, palpitations, weakness Nausea, occasional dry mouth Sharp pain during motion Heartburn and abdominal pain after meals I recently had CBC, LFT, RFT, chest X-ray, and ultrasound—all mostly normal except slightly raised SGOT. I also had MDR TB in the past. I suspect H. pylori or gastritis/ulcer. Please advise tests or treatment.
