Health Problems in Pregnancy

Every pregnancy has some risk of problems. You may have problems because of a health condition you had before you got pregnant. You could also develop a condition during pregnancy. Other causes of problems during pregnancy can include being pregnant with more than one baby, a health problem in a previous pregnancy, substance abuse during pregnancy, or being over age 35. Any of these can affect your health, the health of your baby, or both.

If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Some common conditions that can complicate a pregnancy include

  • High blood pressure
  • Polycystic ovary syndrome
  • Kidney problems
  • Autoimmune disorders
  • Obesity
  • HIV/AIDS
  • Cancer
  • Infections

Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.

Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your health care provider if something is bothering or worrying you.

Uterine Diseases

The uterus, or womb, is the place where a baby grows when a woman is pregnant. The first sign of a problem with the uterus may be bleeding between periods or after sex. Causes can include hormones, thyroid problems, fibroids, polyps, cancer, infection, or pregnancy.

Treatment depends on the cause. Sometimes birth control pills treat hormonal imbalances. If a thyroid problem is the cause, treating it may also stop the bleeding. If you have cancer or hyperplasia, an overgrowth of normal cells in the uterus, you may need surgery.

With two other uterine problems, tissue that normally lines the uterus grows where it is not supposed to. In endometriosis, it grows outside the uterus. In adenomyosis, it grows in the uterus's outside walls. Pain medicine may help. Other treatments include hormones and surgery.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
