Eating Right Into a Leaky Bucket
The PPI Was Supposed to Manage Reflux
It gave me osteopenia, drained my B12, and it was never GERD at all. What I thought was a diagnosis was a guess. It was a hiatal hernia and Barrett’s Esophagus, dismissed for years as stress or acid. The first endoscopy showed precancerous changes.
I'm on endoscopic cancer surveillance every six months now.
Wrong diagnosis, wrong treatment, real consequences, some still unfolding. And I only found out about the nutrient piece by stumbling onto a depletion chart made for clinicians. Not for me. Not handed to me by anyone. Just something I found and recognized myself in.
That was one drug. There were many others. Nobody was looking at the whole list.
You’re fighting to stay upright, eating carefully, rebuilding slowly. Something in the background quietly pulls the floor out from under you. Not labeled. Not flagged. Just accumulating.
Why It Happens
Long-term medications can interfere with absorption or increase excretion of specific nutrients. This isn’t a typical “side effect.” It builds slowly, mimics symptoms you already have, and gets attributed to the illness or to stress.
Sound familiar?
Here’s what that “leak” can look like in practice:
- PPIs and antacids reduce B12 and magnesium absorption over time, worsening fatigue and nerve symptoms already common in dysautonomia. If the underlying cause isn't actually GERD, you're absorbing the depletion without the benefit.
- Corticosteroids impair vitamin D and calcium, quietly, while you're eating the kale.
- Statins deplete CoQ10, amplifying muscle pain that's already part of the picture.
- Methotrexate and anticonvulsants drain folate, with downstream effects on mood and cognition.
- Diuretics pull potassium and magnesium both, which matters enormously in POTS.
None of this is inevitable. Most of it is testable. Some of it is fixable.
The Cognitive and Psychological Weight
Low B12 doesn't just cause tingling. It causes brain fog, anxiety, low mood, a flatness that's easy to attribute to depression or disease progression, or as I was told for years, stress. Magnesium deficiency worsens sleep, irritability, and the nervous system dysregulation already central to dysautonomia. Folate loss affects neurotransmitter production in ways that quietly erode the mental resilience you need just to manage a chronic illness day.
The cruel part: you're putting in the effort. Kitchen work, planning, the discipline of eating well when you feel terrible. And the output doesn't match. That gap is demoralizing in a specific way.
It can feel like confirmation that nothing works, that your body is beyond help.It's not. It's physics. The bucket has a hole. And in my case, the hole had been there for years before anyone looked for it.
Trail-Ready Reference
| Med / Situation | What Gets Depleted | What It Can Mimic |
|---|---|---|
| PPIs / antacids | B12, Magnesium | Fog, neuropathy, fatigue |
| Steroids / Lupus flares | Vitamin D, Calcium | Bone pain, weakness |
| Diuretics / POTS | Potassium, Magnesium | Palpitations, cramps |
| Statins | CoQ10 | Muscle pain, fatigue |
| Methotrexate | Folate | Mood changes, brain fog, anemia |
| Antibiotics (long-term) | B vitamins, Vitamin K | Fatigue, mood, gut issues |
Why You Have to Advocate for Yourself
Most of us were raised to trust doctors completely. They’re the expert. You don’t question, you comply.
But most physicians receive very little formal training in nutrition. Not nothing, but not enough to reliably spot depletion patterns without looking for them.
The problem isn’t malice. It’s time, training, and pattern recognition. “Stress” is often the fastest explanation when the picture is complex.
I was told things were fine for years. The depletion chart wasn’t given to me. I found it. The precancerous changes were found the same way, after pushing for a scope nobody thought I needed.
Self-advocacy isn’t about being difficult. It’s about recognizing you’re the only one in your body full time.
You're allowed to be the expert on your own experience.
What To Actually Do
Bring your full medication list (prescriptions, OTCs, anything you take regularly) to your doctor or pharmacist. Ask specifically about depletion, not just side effects. It’s a different question, and it gets a different answer.
Request basic labs: B12, vitamin D, magnesium, and electrolytes. If you’re on a PPI and nobody has checked your B12, flag it.
Start with food. If something shows up low, then consider targeted supplementation. Not guesswork. Confirmation.
A useful question to bring in:
“Could depletion be contributing to what I’m experiencing?”
And if a medication isn’t treating the right problem, push on that too.
If you’re doing everything right and it still isn’t working, it’s worth asking whether the problem isn’t effort, but leakage.
