Tomorrow she sees another doctor for chronic diarrhea. I know it means more drugs. Why not? A few more won't hurt. It's probably the drugs that are causing the current problems.
I have no confidence in any of them.
While grandma $_its her pants, Dr. Whore wins a trip to France.
Is that wrong? Philosophically yes it is. But remember, when the only tool you have is a hammer, all the world looks like a nail.
Have ya'll have a long talk with your mother's primary care provider? (either a Family Practice Physician, Internist, Family Nurse Practitioner, or Physician Assistant)
The thing I would do is focus on any symptoms she is having and do a good scrub of the $700.00 a month of drugs she is on. What can happen (notice I said can happen) is a drug will cause a symptom that a specialist will treat with another drug. It does take some patience and time on the part of the patient, family, and "doc" to sort through this, but it might help.
Another thought is to see a gerontologist. Their specialty is to take care of old folks and they are quite skilled at getting to the bottom of such issues. (There are also Gerontological Nurse Practitioners who are great at doing this)
