For The Last Six Months I Am Losing Weight @

For the last six months I am losing weight @ 1.5 KG per month. I lost around 10 KG in 6 months. Once in 20 days I see blood in my stool. I also have gastric problem. I got endo and colonoscopy done. In endo report Chronic non-specific duodenitis is indicated. I also took Pantocid HP for one week but the problem still persists. I am feeling weakness and stress now. Kindly advise.
