Information for Patients


Also called: Iron poor blood

If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body.

Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

Conditions that may lead to anemia include

  • Heavy periods
  • Pregnancy
  • Ulcers
  • Colon polyps or colon cancer
  • Inherited disorders
  • A diet that does not have enough iron, folic acid or vitamin B12
  • Blood disorders such as sickle cell anemia and thalassemia, or cancer
  • Aplastic anemia, a condition that can be inherited or acquired
  • G6PD deficiency, a metabolic disorder

Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache.

Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have.

B Vitamins

The B vitamins are

  • B1 (thiamine)
  • B2 (riboflavin)
  • B3 (niacin)
  • B5 (pantothenic acid)
  • B6
  • B7 (biotin)
  • B12
  • Folic acid

These vitamins help the process your body uses to get or make energy from the food you eat. They also help form red blood cells. You can get B vitamins from proteins such as fish, poultry, meat, eggs, and dairy products. Leafy green vegetables, beans, and peas also have B vitamins. Many cereals and some breads have added B vitamins.

Not getting enough of certain B vitamins can cause diseases. A lack of B12 or B6 can cause anemia.

  • Anemia - B12 deficiency
  • Beriberi
  • Methylmalonic acid blood test
  • Niacin
  • Pantothenic acid and biotin
  • Pellagra
  • Riboflavin
  • Thiamin
  • Vitamin B12
  • Vitamin B12 level
  • Vitamin B6
