Tag: Pyrexia of unknown origin

While most fevers are caused by infections, up to 40% of patients with megaloblastic anemia due to Vitamin B12 or folate deficiency may also present with fever. Understanding what vitamin deficiency can cause fever is crucial for investigating pyrexia of unknown origin (PUO) when more common causes have been ruled out.

According to past studies, fever occurs in about 40% of patients with megaloblastic anemia, a condition often caused by vitamin B12 deficiency. While typically low-grade, this symptom can be a surprising and often missed sign that a person's B12 levels are critically low.

Studies indicate that approximately 40% of patients with megaloblastic anemia, a condition stemming from severe B12 deficiency, also experience fever. While not a typical or early sign, the question 'is fever a symptom of B12 deficiency?' is surprisingly relevant in cases involving moderate to severe deficiencies and specific complications.

Studies have shown that fever occurs in approximately 40% of patients with megaloblastic anemia caused by a deficiency of either vitamin B12 or folic acid. This statistic highlights that while uncommon, the answer to "Can you get a fever from vitamin deficiency?" is a definitive yes, though it's typically tied to specific deficiencies and underlying conditions.

Approximately 40% of patients with megaloblastic anemia caused by folic acid deficiency experience a fever. While not a primary symptom, this low-grade pyrexia is a known, though often overlooked, manifestation of severe folate deficiency and the resulting ineffective hematopoiesis.

According to studies, fever has been observed in up to 40% of patients with megaloblastic anemia, a condition often caused by vitamin B12 or folate deficiency. While not widely known, the connection is well-documented in medical literature, meaning that for some, the answer to 'can vitamin B12 deficiency cause fever?' is a surprising 'yes'. This unusual symptom can be an overlooked clue to a serious nutritional issue.
