I have been fortunate to have never had
anemia since developing type 2 diabetes, but I know several of our
support group that have. If you have diabetes, you will need to have
your blood checked regularly for anemia. It is common for people
with diabetes to also end up with this blood condition. It happens
when your body’s red blood cells cannot deliver as much oxygen as
your body needs. If you spot anemia early on, you can better manage
the issues causing it.
Usually, anemia happens because you don’t have enough red blood cells. That can make you more likely
to get certain diabetes complications, like eye and nerve damage. In
addition, it can worsen kidney, heart, and artery disease, which are
more common in people with diabetes.
Diabetes often leads to kidney damage,
and failing kidneys can cause anemia. Healthy kidneys know when your
body needs new red blood cells. They release a hormone called
erythropoietin (EPO), which signals your bone marrow to make more.
Damaged kidneys don’t send out enough EPO to keep up with your
needs.
Often, people don’t realize they have
kidney disease until it’s very far along. But, if you test
positive for anemia, it can be an early sign of a problem with your
kidneys.
People with diabetes are more likely to
have inflamed blood vessels. This can keep bone marrow from getting
the signal they need to make more red blood cells.
And some medications used to treat
diabetes can drop your levels of the protein hemoglobin, which you
need to carry oxygen through your blood. These drugs include ACE
inhibitors, fibrates, metformin, and thiazolidinediones. If you take
one of these, please talk to your doctor about your risk for anemia.
If you have kidney dialysis, you may
have blood loss, and that can also cause anemia.
When your brain and other organs don’t
get enough oxygen, you feel tired and weak. Other signs you may have
anemia include:
- Shortness of breath
- Dizziness
- Headache
- Pale skin
- Chest pain
- Cold hands and feet
- Low body temperature
- Rapid heartbeat
A complete blood count gives your
doctor a good picture of what’s going on in your blood. It counts
your red and white blood cells and platelets, and it checks whether
the red blood cells are a normal size.
It also checks the levels of hemoglobin
in your blood and your blood volume. If your hemoglobin levels are
low, you may be anemic. The normal ranges are 14 to 17.5 for men and
12.3 to 15.3 for women. If you have a lower percentage of red blood
cells in your blood, you may be anemic.
If you are, the next step is to find
out why. Your doctor may test you for:
- Iron deficiency
- Kidney failure
- Vitamin deficiency
- Internal bleeding
- Bone marrow health
If you’re anemic because your iron
levels are low, it may help to eat iron-rich foods and take
supplements. For people on kidney dialysis, it's best to get iron
injected directly into a vein.
If your kidneys don’t make enough EPO
-- the hormone that boosts the level of red blood cells you make --
your treatment may be a synthetic version of the hormone. You’ll
get an injection every week or two, or you’ll have it during
dialysis. It raises hemoglobin for most people, but it may also
increase your chances of a heart attack or stroke. Your doctor needs
to watch you closely while you’re on it
If your anemia is severe, you may need
a blood transfusion.
You can lower your risk. Make sure you
get enough iron from the food you eat. Most adult women need about 18
milligrams every day. Men need about 8.
Good sources of iron include:
- Iron-fortified breads and cereals
- Beans and lentils
- Oysters
- Liver
- Green leafy vegetables, especially spinach
- Tofu
- Red meat
- Fish
- Dried fruit, like prunes, raisins and apricots
Your body absorbs iron better if you
have it along with food that contains vitamin C, like fruits and
vegetables. Coffee, tea, and calcium can make you absorb less of it.
High blood pressure and high blood
sugar cause the kidney damage that brings on anemia. If your doctor
has prescribed you medication for either high blood pressure or high
blood sugar, it’s important that you take it. A good diet and
regular exercise also help.
