Blood Disorders

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.

Types of blood disorders include:

  • Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots
  • Anemia, which happens when your blood does not carry enough oxygen to the rest of your body
  • Cancers of the blood, such as leukemia and myeloma
  • Eosinophilic disorders, which are problems with one type of white blood cell.

Twins, Triplets, Multiple Births

If you are pregnant with more than one baby, you are far from alone. Multiple births are up in the United States. More women are having babies after age 30 and more are taking fertility drugs. Both boost the chance of carrying more than one baby. A family history of twins also makes multiples more likely.

Years ago, most twins came as a surprise. Now, most women know about a multiple pregnancy early. Women with multiple pregnancies should see their health care providers more often than women who are expecting one baby. Multiple pregnancy babies have a much higher risk of being born prematurely and having a low birth weight. There is also more of a risk of disabilities. Some women have to go on bed rest to delay labor. Finally, they may deliver by C-section, especially if there are three babies or more.

Parenting multiples can be a challenge. Volunteer help and support groups for parents of multiples can help.
