Natalie,

Just as chemo can cause PN, it can cause ALL forms of PN, to include autonomic dysfunction. Autonomic neuropathy is a subset of PN and causes problems with BP, heart rate and GI emptying. You need to have a gastric empty study done to determine if you have gastroparesis. If you Goolge this condition you may find your symptoms match. If so, then talk to your doctor about getting this non-invasive test (you just eat some contrast laced scrambled eggs and lay down while they do nuclear scans for 2 hours to determine transit time).

Unfortunately, there isn't a wide range of treatments available. BUt life-style change and diet change can help. All depending on where you are located, there are medications available to help. In the US, nothing is approved, but in the UK, Canada, etc you can easily get Domperidone, which can be quite helpful.

If gastroparesis is confirmed, you can eat smaller meals, and follow a gastroparesis diet (you can find info online), but basically avoid raw veggies, fruits, and nuts (cooked/steamed is ok). Grinding your food in a blender is also helpful (the flavor does NOT change, but of course texture does). Also walking after eating is helpful (letting gravity promoted increased transit). Don't eat after 5-6 PM to avoid night time problems and sleep on a wedge pillow to again allow gravity to help movement in the night.

Hope this helps.
