A member asked:

Tingle in hands and feet, fatigue, lightheaded, trouble thinking. been on 150mg zantac and 80 mg protonix 4 months now. could this be low b12?

2 doctors weighed in across 2 answers

Possible: Long term use of PPI(protonix) could cause decreased vitamin B12 absorption. You should be tested.

Certainly, vitamin deficiency could cause what you describe. The tingling could represent peripheral nerve problems, the thinking process perhaps cognitive clouding. Checking B-12 function would be one of several tests to consider.

I have occasional lightheadedness, and on other occasions I feel a head-rush similar to an adrenaline rush. I also sometimes have a tingling sensation in my feet and hands. Should I be worried about brain tumors or ALS? Or is this anxiety 101?
