Question 1

What deficiency causes extreme tiredness?

Accepted Answer

Iron, vitamin D and vitamin B12 deficiencies are the most common, alongside thyroid dysfunction. All four show up on a single blood panel.

How long is too long to be tired before I should worry?

Accepted Answer

More than two weeks of tiredness that sleep doesn't fix is the general threshold doctors use before investigating further.
