What Your Bloodwork Isn't Telling You

The blood test comes back and something is low. Iron, ferritin, vitamin B12, vitamin D, perhaps all three. For the first time in months, the tiredness has a name.

The doctor prescribes a supplement and tells you what to eat. You take the tablets properly, add the foods you were advised to include and return for the next test. The number improves. You feel relieved. The problem appears to have been found and corrected.

Six months later, the report is low again.

The doctor might change the dose or get some more investigations or maybe you are told that your diet still needs work, even though you have been carrying the tablets in your bag, setting reminders and doing everything you were asked to do.

After repeating this cycle a few times, the question changes.

It is no longer simply, “What should I take?”

It becomes - 

“Why does my body keep losing the same thing, no matter what I put into it?”

That question still needs medical investigation. Recurring deficiencies can involve blood loss, absorption problems, medication effects, increased requirements, autoimmune conditions and other physical causes that require proper assessment.

But bloodwork is not designed to show the whole life in which the deficiency keeps returning.

A deficiency is more than a supply problem

We usually understand nutrient deficiency through a simple equation. If iron is low, perhaps there is not enough iron entering the body. Increase the supply and the number should rise.

That explanation is often correct, but the body is more complicated than a storage container waiting to be filled.

A nutrient level is the result of an ongoing negotiation between what enters the body, what can be absorbed, what is being used, what is being lost and whether the body has the conditions needed to rebuild its reserves.

Change any one of these, and the number can fall even when the person is eating carefully and taking supplements.

The report can show what is low. It cannot show the breakfast postponed because somebody needed you, the meal eaten while answering calls, the broken sleep, the antacid taken repeatedly, or the years in which your own hunger became less urgent than everybody else’s needs.

It cannot show the life around the intake.

What hides inside the word ‘stress’

Fear, guilt, resentment, helplessness, grief, overgiving and constant responsibility are usually flattened into one word: stress.

The word is convenient because it allows everyone to move on quickly.

• “Reduce stress.”
• “Try to relax.”
• “Think positively.”

But there is a difference between a busy week and living in a relationship where your voice carries no weight. There is a difference between working hard for something you chose and carrying a family role you are not allowed to leave. There is a difference between temporary worry and a body that has spent years waiting for the next problem.

These experiences change ordinary physiology and ordinary behaviour. Appetite becomes irregular. Meals are delayed. Sleep remains shallow. Digestion becomes unsettled. The person may rely on caffeine to continue, sugar to soften the evening and antacids to keep the stomach manageable.

Long-term emotional strain can also alter gastric function, including secretion and motility. Stress does not affect every stomach in the same way, but in some people reduced acid availability, sometimes compounded by frequent antacid use or long-term acid-suppressing medication, can make non-haem iron more difficult to absorb.

This is one possible pathway. It is not the explanation for every recurring deficiency, and prescribed medication should not be stopped or changed without medical guidance.

The larger point is simpler.

What enters the mouth is only one part of what the body eventually gets to keep.

The person who does everything right

The people most frustrated by recurring deficiencies are often the people trying hardest to correct them. They take the supplement regularly, research foods, improve the diet, exercise or sit in sunlight. They repeat the tests and keep every report in a folder.

This person may already be managing a home, work, parents, children, finances and the emotional temperature of several relationships. Even illness is approached through discipline. The body concern becomes one more responsibility to manage correctly.

• Take the tablet.
• Eat better.
• Sleep on time.
• Do not complain.
• Do not inconvenience anyone.
• Do not become a burden.

When the number falls again, the person blames the one part of the system that has already been working hardest: themselves.

• Maybe I was not consistent enough.
• I should have taken a better supplement.
• I need to exercise more.
• I did not manage stress properly.

The emotional layer is not meant to add another accusation. It is meant to ask whether the body has been living under an instruction that keeps using the same resource faster than it can be rebuilt.

Iron: strength continually spent

Iron belongs to strength, movement and the capacity to meet the world with force. Now consider a person whose strength is constantly used to tolerate rather than change.

She manages the family but cannot insist that anyone else share the burden. He handles every practical crisis but has very little authority inside the relationships where he most needs a say. Anger is converted into understanding. Exhaustion is converted into another plan.

The strength exists. It is simply never used on the person’s own behalf. The body may receive iron through food or tablets while the life keeps spending strength without allowing any of it to become self-protection.

Protein: the one holding everything

Protein belongs to structure and repair. Now consider the person who is the structure for everyone else. They remember, arrange, repair and hold. Their own needs remain postponed because somebody else’s problem feels more urgent.

“I eat last” is not merely a sentence about meal timing. It can describe an entire life in which nourishment continually moves outward before the person allows any of it to stay.

The person is held together by duty. Nobody notices that they are no longer being held.

Magnesium: the body that never unclenches

Magnesium belongs to relaxation and release. What about the person whose body has forgotten what off duty feels like? They lie down but continue planning. They sleep but remain alert. They take a holiday and spend it ensuring everyone else is comfortable.

Relaxation feels risky because it creates the possibility of missing a problem, losing control or allowing somebody else to make a mistake.

The body may be physically still. It has not actually stood down.

The other shortage

The deficiency shown in the report is real, and it still needs treatment. But it may not be the only shortage operating in the person’s life.

There may also be very little permission.

Permission to rest before everything is complete, to receive without immediately repaying, to stand firmly without being called difficult, to eat before everybody else has been taken care of and permission to admit that something is too much before the body has to prove it.

The supplement supplies the nutrient. It cannot change the life in which nourishment continually moves outward while pressure continues to move in. But the recurring loop may need more than one form of attention.

What bloodwork cannot ask

Bloodwork can tell you that ferritin is low. It cannot ask why your strength is always available to everyone except you.

It can show low vitamin D but cannot ask when you first decided that being visible was unsafe.

It can show low magnesium but not why rest still feels like neglecting a duty.

Those questions belong to a different conversation.

If the same deficiency keeps returning, continue the investigations and treatment. But also begin asking:

• What does my daily life keep asking the body to spend?
• Where does nourishment move outward before it reaches me?
• What becomes uncomfortable when I rest, receive, stand firmly or come first?
• What has the body learned to survive, and does it still need to survive that way now?

The purpose is not to replace the explanation on the report. It is to understand the life in which the report keeps repeating itself.

Continue your medical care and supplementation as advised by your doctor. This work sits alongside conventional treatment, not instead of it.
