Hello @beth11,

Low iron is an interesting piece of information. It can indicate celiac disease. You might discuss this with your hematologist

Here is a link to some info about celiac disease, https://www.mayoclinic.org/diseases-conditions/celiac-disease/symptoms-causes/syc-20352220

If you read the article you will see that celiac disease in adults often does not cause digestive problems but other symptoms, up to and including neurological conditions. I'll copy that part of the article here:

"However, more than half the adults with celiac disease have signs and symptoms unrelated to the digestive system, including:

Anemia, usually from iron deficiency
Loss of bone density (osteoporosis) or softening of bone (osteomalacia)
Itchy, blistery skin rash (dermatitis herpetiformis)
Mouth ulcers
Headaches and fatigue
Nervous system injury, including numbness and tingling in the feet and hands, possible problems with balance, and cognitive impairment
Joint pain
Reduced functioning of the spleen (hyposplenism)"
