You often wake up tired, even after a good night’s sleep. You’re
always feeling cold, and reaching for a sweater, regardless of the temperature.
If these statements are true, mention it to your doctor. Constant chills
and fatigue may mean you are low on iron.

“Causes of an iron deficiency can range from poor diet to a
serious illness,” says family medicine physician David Brill, DO.
“Other factors to consider are your age, gender and medical history.”
What are the symptoms of iron deficiency?
Your body uses iron, a mineral, to make hemoglobin. This helps
your blood carry oxygen throughout the body. If
you aren’t getting enough iron, this can limit oxygen flow and anemia may
develop.
If you show up at the doctor’s office looking pale, especially
around the eyes, and complaining of constant chills and exhaustion, your doctor
is likely to test for iron deficiency. Other symptoms include bruising, dry
skin and a bloated feeling.
Who is most at risk for iron deficiency
anemia?
Women. “By far, women are more at risk of iron deficiency, which can
start with the onset of menstrual cycles,” Dr. Brill says. Women also are at a
greater risk of auto immune disorders and hypothyroidism, which may cause
anemia. Pregnant women may need iron supplements, as well as babies who are
solely breast-fed after six months.
Older adults. As you age, your appetite typically decreases. Your more
meager meals may lack good sources of iron.
Those taking certain medicines. Medicines and treatments that can rob the
body of iron include: blood thinners, such as aspirin or prescription medicine,
such as Coumadin® (Warfarin). Chemotherapy and other cancer-targeted therapies
can also strip away iron.
Those with a chronic illness. Illnesses that cause blood loss, such as
ulcers and colon cancer, are sometimes the underlying cause of an iron
deficiency.
How do doctors diagnose anemia?
Blood tests can identify an iron deficiency, but that’s only
part of the evaluation during an office visit. Those with mild symptoms may
discover they are anemic during an annual checkup.
“We always listen to what the patient is telling us,” Dr. Brill
says. “A good history and physical are tools that no amount of technology can
beat.”
Lab tests then confirm the diagnosis. “I would recommend annual
lab screenings so we have a trail to look back on if there is a change,” he
says.
How do doctors treat an iron deficiency?
Your doctor first will determine what is causing your anemia.
Treatment will then focus on both the iron deficiency and the underlying cause.
If your diet is the culprit, Dr. Brill offers several tips for improving your
iron intake.
“An especially good source is quinoa — one serving has 5 mg or
about 1/3 of your daily needs,” he says.
Other good sources include:
·
Spinach (squeeze on
some citrus, like lemon, to help release the iron).
·
Red meat.
·
Oysters.
·
Peanut butter.
·
Pumpkin or squash
seeds.
·
Kidney beans and
lentils.
·
Dried fruits.
Your doctor also may recommend an iron supplement available
without a prescription.
“There are pros and cons for every type of treatment,” Dr. Brill
says. “We take into account the cause and the severity of the anemia. If the
severity is life-threatening, we can do a blood transfusion. This, however, is
not the answer for everyone.”
