I'm right there with your wife. I have advanced cardiac autonomic neuropathy with vagal nerve involvement. My digestive system is shutting down. It started with gastroparesis and has led to dysphagia and a colon that doesn't really have the peristalsis movement anymore. I have been through 3 feeding tubes, and if I hadn't had complications from the feeding tubes, they would've been awesome. My diabetes type 1 is completely out of control because I don't digest food properly. The feeding tube gave me control. Plus, you can still eat with a feeding tube...so it is not as scary and limiting as people think. I had it removed due to rare complications and cannot get another. I also have severe swings in blood pressure to the point that it is threatening my life. Dizziness and weakness are hallmark symptoms. They are talking to me about a vagus nerve stimulator. My sister had the stomach stimulator/pacemaker and it didn't really work for her. Anyway, wanted to reach out with my experience to show you...your wife is not alone. I pray things are going better.
