Except that in all these cases the underlying cause was /is arterial blood flow. There was no possible way that a lay person can get these correct, not even blood pressure measurements will be definite. A stool test might help eliminate some causes of the burping, blood tests the iodine deficiency . The self medicator will probably be dosing on Galviscon, and a double brandy to ensure sleep and block out tinnitus.
Did I mention iodine deficiency? That is but one cause of thyroid issues.
I simply pointed out that thyroid issues need to be considered as possibilities - absolutely NOT that they have been identified, or any treatment started or changed.
There are many issues with self-medication of all sorts. But people get into positions from which they have no acceptable alternative. Remember, it is their choice to refuse any treatment.
I wouldn't class Gaviscon or brandy as self-treatment of the disorders - just attempted symptom relief.
Issues of blood flow are themselves all too often caused by thyroid issues. And missed. Inappropriate thyroid hormone levels can result in remodelling of blood vessels and peculiar blood flows. They can be visibly altered such that just looking at a person's arm or torso, you see oddities.
I see person after person after person who was prescribed a medicine, typically a proton pump inhibitor or an H2 receptor antagonist, for reflux or burps. The doctor having missed both possibilities we have discussed - blood flow and thyroid issues. Given the context I see them in, thyroid is often eventually understood to have been the cause. Further, use of these can also impact on absorption of nutrients - such as B12. As B12 is likely already low (lots of links between low B12 and thyroid disorders), this can have the serious effect of causing real B12 deficiency.
