Problems During Pregnancy
Understanding pregnancy complications and how to manage them for maternal and fetal health
Quick Facts
- Type: Obstetric Complications
- ICD-10: O00-O9A
- Prevalence: 10-15% of pregnancies
- Critical Period: All trimesters
Overview
Problems during pregnancy encompass a wide range of medical conditions and complications that can arise at any point during the gestational period. While most pregnancies proceed without major complications, approximately 10-15% of pregnant women experience some form of pregnancy-related problem that requires medical attention and management.
Pregnancy complications can range from minor, manageable conditions to serious, life-threatening situations affecting both maternal and fetal health. These problems can be broadly categorized into those that existed before pregnancy (pre-existing conditions), those that develop during pregnancy (pregnancy-specific conditions), and those related to the developing fetus.
Early identification and proper management of pregnancy problems are crucial for ensuring the best possible outcomes for both mother and baby. Modern prenatal care, with regular monitoring and screening, has significantly improved the ability to detect and manage pregnancy complications early, reducing maternal and infant mortality rates.
Understanding the warning signs and risk factors for pregnancy problems empowers expectant mothers to seek timely medical care and actively participate in their prenatal care. While some complications cannot be prevented, many can be effectively managed with appropriate medical intervention, lifestyle modifications, and close monitoring throughout pregnancy.

Frequently Asked Questions
Approximately 10-15% of pregnancies experience some form of complication requiring medical intervention. However, with proper prenatal care and monitoring, most complications can be managed successfully, and the vast majority of pregnancies result in healthy mothers and babies.
While not all pregnancy problems can be prevented, many can be reduced through preconception planning, early prenatal care, healthy lifestyle choices, and management of pre-existing medical conditions. Taking folic acid, avoiding harmful substances, and maintaining a healthy weight are important preventive measures.
Ideally, prenatal care should begin as soon as you know you're pregnant, preferably before 10-12 weeks of pregnancy. Early prenatal care allows for timely screening, risk assessment, and intervention if problems are detected. Preconception care is even better for planning a healthy pregnancy.
Yes, certain pregnancy complications become more common as maternal age increases, particularly after age 35. These include chromosomal abnormalities, gestational diabetes, preeclampsia, and miscarriage. However, many women over 35 have healthy pregnancies with appropriate prenatal care and monitoring.
For low-risk pregnancies, typical prenatal visit schedules are: monthly until 28 weeks, every 2 weeks from 28-36 weeks, and weekly after 36 weeks. High-risk pregnancies may require more frequent visits. Always follow your healthcare provider's recommendations for your specific situation.
Follow your healthcare provider's instructions carefully, attend all scheduled appointments, monitor symptoms as directed, and don't hesitate to call with concerns. Many pregnancy complications can be successfully managed with appropriate medical care, lifestyle modifications, and careful monitoring.
