Why are my hemoglobin values consistently low?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My primary care physician and his PA overlooked at least 10 years of consistently low hemoglobin and hematocrit levels. When I recently had flu-like symptoms without any upper respiratory symptoms, I went to a new PCP who ordered the blood test.

That PCP noted the low hemoglobin and hematocrit and had me repeat the tests six weeks later. Still small, she referred me to a gastroenterologist to check for bleeding. He had access to all of my blood tests for the last 12 years and was the one who pointed out that the levels had been low.

He concluded that there was no blood loss. The PCP then referred me to a hematologist. I am waiting to be seen by him. Of note, I have been consistently exhausted with low energy and motivation. I also have a multiple-decade history of recurrent aphthous stomatitis that is worsening. My blood results also showed a Vitamin B-12 level in excess of 1000 and a healthy iron level. I am wondering what could be going on. Any thoughts or recommendations you may have would be much appreciated.

Please help.

Hello,

Welcome to icliniq.com.

If hemoglobin level and hematocrit are low, then iron deficiency anemia could be possible. I need to know what your hemoglobin value is. So kindly attach your CBC (complete blood count) report to give a further comment regarding that.

The B12 can be high due to supplement intake, liver disease, kidney disease, or myeloproliferative blood disorder. So apart from CBC, you can investigate with liver and kidney profile reports as well to exclude liver and kidney disease. If all comes clear, then there is no need to worry because B12 is a water-soluble vitamin readily excreted through the kidneys. Kindly attach your reports.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.

Patient's Query

Hi doctor,

I only have the last three blood tests available; see attached. The gastroenterologist I saw said that I had chronic normocytic anemia with hemoglobin and hematocrit levels hovering between low normal and mild to moderately low throughout that period. He said that the hemoglobin was as low as before for years at a time, which may have corresponded with a prostate biopsy I had.

Kindly help.

Hello,

Welcome back to icliniq.com.

I have seen your last three attached reports (attachment removed to protect patient identity).

In the previous two reports your hemoglobin level and hematocrit levels are slightly low. However, your iron profile reports are entirely normal. So in such a case any bleeding history, if present, needs to be searched for.

A stool occult blood test should be done to check for bleeding from the intestine or stomach by any ulcer. A stool routine micro examination also should be done. Stool analysis will reveal any parasite if present. If all reports regarding bleeding are normal, as you said, then mild low hemoglobin could be due to nutritional deficiency. Your hemoglobin level and hematocrit are mildly reduced. So need to be concerned, but do not worry.

You can take iron-rich foods like boiled red meat, green leafy vegetables, pumpkin seeds, and beans, etc. B12 is a water-soluble vitamin. Mostly it will readily be excreted through the kidney. Kindly repeat B12 after a few weeks to check the level.

I hope I have answered your question.

Let me know if I can assist you further.
