Hello With such type of symptoms , I would come up with these possibilities , these include : 1 The first possibility is of peptic ulcer disease or hiatus hernia . Diagnosis can be confirmed by Upper G I endoscopy. Try raising the head of your bed about 4 inches with blocks. It might also help to avoid eating or drinking for 2-3 hours before you lie down. To control stomach acid ( HEART BURN ) ,one should not drink alcohol or drinks with caffeine in them or eat chocolates or greasy of oily foods . Also take some antacid but if symptoms are severe , you may need drugs like proton pump inhibitors like pantaprazole-D ,once or twice in days . 2 the next reason of such symptoms may be due to tension or worries or stressful life , so if possible avoid these predisposing factors. 3 Loss of appetite may be due to heart burn or hyper acidity or tension. So when such patient visit I prescribe them to take cyproheptadine+sorbitol=tricholine syrup . This will not only boost appetite but also help in digestion. Bad smell in the stool may be due to indigestion . Hope this will help you.
