HI, thanks for using healthcare magic
There are a number of different possible reason for
d dimer increase.
D dimer is the break down product of
fibrin which is a type of protein formed during clotting of blood.
Increases in d dimer can occur in
pregnancy as you mentioned but the other causes include: (1)any form of inflammation- inflammation can be due to allergies, infection,trauma, cancer
(2)
liver disease
(3)heart disease
(4)high levels of triglycerides
(5)high bilirubin
(6)high
rheumatoid factor eg as in rheumatoid arthritis
It can be repeated to see if it remains elevated. The symptoms of headache and the other pain may be due to inflammation/irritation of some aspect of the body.
This may cause an increase, when you are feeling better, it should be repeated.
I hope this helps
