I was looking for information for myself, and came upon your post. After reading it,I think I may have some ideas for you. I have a motility problem. I have gastroparesis - which basically means the nerve in my stomach does not work well. I take medication for it and live on a liquid diet. I also have some sort of motility problem in my bowels. The medication for my stomach helps things to move along otherwise I get very sick from being constipated. I also take 2 doses of miralax every evening to make sure that things move along. With my condition I can only drink liquids, but there are varying degrees of motility problems.....some people can eat more solid food others cannot. Generally people avoid fiber and too much fat as they digest slowly. Now let me tell you what can happen to me if things get backed up and I get the least bit constipated. My chest feels tight, I get heart palpitations, I have anxiety and feel very scared and this anxiety usually comes in waves, and finally I can feel dizzy and my arms can feel numb. In my situation I have learned that all of these problems are related to my motility problem. As soon as things start moving along, it starts to go away. For me
I stop all food and only drink gatorade or water for the day. I drink as much as I can as the more liquids you have the sooner you get better. I also take several doses of miralax. Gradually I notice the palpitations and all the other symptoms go away. So if you do have a motility problem in your bowels this could be the reason for your palpitations and anxiety. You could try drinking about 8 glasses of water daily and taking miralax for a few days and see if you feel better. You could also see if you feel better if you change your diet. Generally more fruits and vegetables and fiber lessen constipation. However, if you have a motility problem where your bowels are just slow moving, or your stomach is slow moving you may need to actually do the opposite and lessen or eliminate fiber and fat. You could talk to your gastro doctor about getting tested for motility problems also. Hope I was of some help
