Symptoms; Metallic taste in mouth; metallic/sulphurous odour of stool

Background:~ My current GP thinks I have IBS, I am booked for an endoscopy this July with the NHS of GB. I have had several blood tests for tropical disease/bacteria proved negative.

I have had gastric problems for 5 year or more now, no pattern.  I suffer with sever bloating every few weeks; diarrhoea frequently (3x a week approx.); occasional bleeding (v. red, 1 period a month, over 2 to 3 days); occasionally I feel nauseous and am sick - during this I feel exhausted.  Also something else I think maybe connected I have a metallic taste in mouth and a metallic/sulphurous odour to my stool, not necessarily at the same time.  Any ideas what could be causing these signs/symptoms?

First things that come to mind is GERD, which can cause taste changes.  Other possibilities would be inflammation of the upper digestive tract as well as an ulcer.  Diarrhea can certainly be caused by IBS, but also consider malabsorption as well as inflammatory bowel disease.  

The evaluate the upper digestive tract, the endoscopy is the reasonable next step - this is the most comprehensive test.  If negative, I would consider an ultrasound to evaluate the liver and gallbladder.  I would also consider a blood test for H Pylori - a bacteria associated with ulcers and inflammation (this may have already been done).

A lower endoscopy - either flexible sigmoidoscopy or colonoscopy - can be considered to evaluate the diarrhea.  Malabsorption can be evaluated via a fecal fat test or blood tests for celiac disease.  If all the tests are negative, then IBS can certainly be considered and treatment be optimized.  

Followup with your personal physician is essential.
