The medical term for frequently waking up at night to urinate is nocturia. Broadly, this may be because of excessive urine production in general (poorly controlled diabetes mellitus, diabetes insipidus), excessive urine production only at night (congestive heart failure, obstructive sleep apnea, certain drugs), inability to empty the bladder (prostate enlargement) or inability to fully fill the bladder (bladder overactivity, bladder inflammation).

A consultation with a urology doctor will help diagnose the cause and set you on the path toward a more restful night. Untreated nocturia is associated with a poorer quality of life and can lead to depression, cognitive dysfunction, and increased risk for falls and fractures.

Hi @Edawaw if your ferritin is consistently low, you may have iron deficiency. If your haemoglobin level is below normal, then you should seriously consider iron replacement. 
First we have to make the diagnosis, you have to look at the iron saturation (it should be low ) and total iron binding capacity (it should be raised).
If you have these results, then consider increasing iron in your diet such as eat more red meat, take iron supplements.
Concurrently, you have to see your doctor and find out the cause of the low ferritin level. Is it blood loss in the gut, blood loss through menses or reduced dietary iron intake

@A-Marie-88 , the report seem to suggest there is a degree of iron deposition with the history of haemochromatosis. While it is less likely for pre-menopausal women to have significant liver disease/enlarged liver from haemochromatosis. I would reocmmend you see a liver specialist for other causes of enlarged liver. The prominence of portal triad is rather nonspecific.
Hope this helps!
