hello sir,
As you mention about your mother,I think this low
hemoglobin problem is unrelated to previous illness.
But
anemia i.e low hb is not good for patient of
hypertension and stroke as anemia causes more workload
on heart.
There are lots of causes of anemia .But in age group of 70 year old female history of passing blood in
urine ,stool or per vaginal bleeding is important.Also any history of gastric or intestinal operation is
important.
On investigation -peripheral blood smear s/o microcytic or macrocytic picture is also important.As causes
are different for both this condition.
Microcytic picture is most commonly consistent with iron deficieny and Macrocytic due to vit b12 an folic
acid deficiency.
So sir,I suggest you to do peripheral blood smear,urine microscopic examination,stool for occult blood.
According to peripheral picture iron or vit b12 ,
folic acid supplementation.
Also important is diabetic control an control of
high BP ,as this are independent risk factor for recurrent
stroke.
