Hi, Ann: I do not think that it would be out of place for you to suggest further medical consultation for your Mom if you think and feel it is necessary to do so. You worry about your Mom and that is understandable. As you've stated, both parents seem to agree with your concern which is already a good start. It would have been a more difficult position to work along with if they did not. As long as you keep them involved and you consult with them all the way throughout the processes and for so long as they agree, I don't think you would be disenfranchising them of their autonomy to make decisions over their health, life etc. I pray that all will be well with your Mom and that nothing more than an adjustment of medication would be called for.
