Looking for help on my almost constant lightheadedness that ALWAYS goes along with urges for b.m.'s. Sometimes b.m's bring on the lightheadedness...they are always loose-no straining. Been to fam dr and neuro. mri's,ultrasounds,ct scans,blood all normal. never been to gastro dr yet. Neuro found "slight"neuropathy but I dont think its related to my lightheadedness with bowel area urges. Somedays I feel great(clear head)and thenI notice that I've not had a bowl movement that day.weird. the lightheadedness is not spinning but weak, tired,faint feeling, though i've never actually fainted. when i have the urge for b.m.s with the l.h. I usually don't even have a b.m...just the feeling to. I eat a mostly veget. diet-lots of raw food, org. carrot juice and fresh veggies. I have a hard time losing weight too(but i'm not at all overweight) and a very easy time putting ON weight with what most would call a regular meal. Could this be related? The l.h. affects my day--tired-hard to give the energy to 3 small kids that i want to give them!Any ideas????
