7. Digestive issues
Symptoms may include nausea, diarrhea, constipation, bloating, or loss of appetite.
8. Heart palpitations
A rapid or irregular heartbeat can occur due to anemia caused by low B12 levels.
Who Is at Risk?
Older adults – B12 absorption naturally decreases with age
Vegans and vegetarians – B12 is mainly found in animal products
People with digestive disorders – Conditions like Crohn’s disease, celiac disease, or prior weight-loss surgery can reduce absorption
People taking certain medications – Long-term use of proton pump inhibitors or metformin can interfere with B12 absorption
What to Do
If you notice these symptoms or suspect a deficiency, consult a healthcare professional. A simple blood test can confirm low B12 levels, and treatment may include supplements, injections, or dietary changes.
Early detection is important—untreated B12 deficiency can lead to permanent nerve damage.
