I would like to know if N.H.S G.P can keep a very elderly patients condition secret?

I am 82yrs old.Have widespread Arthritis.In recent months I have had a colonostomey.Severe Diviticulitis diagnosed. Since then I have had much bloating of my stomach. I think I need an investigation of my stomach. G.P. gives anti spasmodic capsules. Is he refusing to take matters futher because of restraint in caring for the very elderly
