Gi issues for last 4 months. Started with wrong omeprazole prescription for chest trouble. Erosive gastritis in antrum area found on nov 4th endoscopy. No h pylori. Ct on october 24th found diverticulosis. Ultrasound done late december suggests grade 1 fatty liver. Lost 18 kgs in 100 days. Rapid heart rate (20-25 hr more in mornings from oct end, esp. On standing up). It started off with me having some pores in chest in july. Since I had a history of hiatus hernia for which I used to take omeprazole before 2016, I was given omeprazole 20 mg in uk. After 3 months, I started developing some crawling, dripping feeling left of umbilicus. Omeprazole was increased to 40 mg. On october 12th, I had severe heartburn. October 19th I got shingles. I was on acyclovir, the shingles patches disappeared. Then I started losing weight. Every night I lost 1 kg to 1.25 kgs. My heart rate went up from last week of october. I developed intense anxiety. Currently - I lose weight daily. Have diarrhea and have 3-4 times bowel movement (mostly type 6 stool - soft, broken, thin, with mucus), have severe discomfort / gnawing feeling 1.5 hours after food, some days severe tender pain left of umbilicus, dripping/crawling feeling left of umbilicus, pain/pricks below ribs. No blood in stool. I feel week. I also have chest tightness in the morning. I feel crawling feeling in the back where stomach, it is quite irritating. Other symptoms are - ear full, ringing in ears, crawling in the back, numbness/tingling in toe fingers and ulnar finger (gets numb every day while sleeping), polyuria (i urinate lot more than I used to), orthostatic hypotension, possible postural orthostatic tachycardia syndrome (every day in the morning the heart rate goes upon standing). Many blood and stool tests have been done. Key markers outside range are a) hgb is 170 and hct 49.6 in one report, whereas one taken 3 days later shows hgb 150 and hct 45. B) food intolerance for cow milk, oat, rajma, maize etc. Vit e toxic level. B1, b3, b9, b12, selenium low c) lipase 61 I got cavity on jan 18th. Just recovered. Taking montek lc for 2 weeks, will continue for 2 more weeks. It seems to have slightly improved pain symptoms. I'm going to have pet scan tomorrow. If it is inconclusive they are suggesting colonoscopy current medications: famotidine 20 mg (1 or 2) propranolol 10mgx1 (1 or 2) vitamin d 60k once a week neurobion. I have met few doctors. One doctor prescribed lesuride 25 mg, looz fibre another doctor prescribed - normaxin rt, colapsa retard. Another suggested to stick to fomatadine, propranolol and take normaxin rt only when I have pain, and have vzl3 another doctor has prescribed - ivoral forte 2 days, rcifax (rifaximin) 550g x 3 - 2 weeks, econorm - 30 days, menoctyl - 40 mg - 3 a day for 15 days queries I have are a) can weight loss be owing to creams or microscopic colitis. Could that be the reason behind weight loss. But my calprotectin is within range b) which doctor's prescription should I take of the four given above c) when I have severe pain next to umbilicus what can I take to reduce pain e) when I have diarrhea can I take eldoper once in a while f) how to arrest weight loss, what food I can take safely in my condition to either stop weight loss or increase? G) could I have secondary polycythemia. I had severe sleep apnea. Because of aerophagia and weight loss I have stopped cpap. Should I test this in more detail h) many of my symptoms - fast pulse, diarrhea, sweating, weight loss - are inline with thyroid problems. But my tsh (2.11), t3 (9.4), t4 (7.1) are normal. Tgo ab, tpo ab were checked in november. They were there but within range. Haven't checked thyroglobulin and tshr ab. One doctor feels propranolol could be masking thyroid issues. Should I be looking into this? I don't have goitre or pain in neck. Could it be painless i) I am worried about pet ct and associated radiation. My creatinine is .93 and hba1c is 5.6. Given increased urination, should I be worried about ct contrast?
