For the last couple of months my husband has been burping (particularly) with the odd related hiccup at all times of day or night, regardless of whether he has eaten or not. I mentioned it to the doctor on a visit, but he didn't seem to attach any importance to it. Could this be a dementia-related symptom to do with growing difficulty in digesting? Which is why the doctor didn't pursue? But didn't clarify? It continues apace. Has anyone experienced this?
