After the Surgery
B12 deficiency following gastric surgery

“I survived cancer but nearly lost my mind to B12 deficiency.”
George's Journey
The Beginning
In 2020, I was diagnosed with early stomach cancer. The surgery - a partial gastrectomy - was successful, and I was cancer-free. I was so relieved to survive that I didn't think much about the follow-up care.
The Struggle
A year after surgery, I started feeling unwell again. Severe fatigue, weakness, and I was becoming confused. My wife thought the cancer had returned. I was also becoming depressed and unsteady on my feet.
Getting Diagnosed
At my oncology follow-up, they ran blood tests and found my B12 was severely low at 98 ng/L. They explained that removing part of my stomach meant I could no longer absorb B12 from food - something I hadn't been warned about.
Recovery
Once I started B12 injections, the improvement was steady. My energy returned, the confusion cleared, and my mood lifted. It took about 6 months to feel like myself again.
Where I Am Now
I now have B12 injections for life, along with iron infusions and other supplements. I'm grateful my oncology team caught this, but I wish I'd been warned it was a risk of the surgery.
