Intrauterine Growth Restriction Causes, Symptoms and Treatment

Intrauterine Growth Restriction (IUGR) refers to a condition in which a fetus fails to achieve its expected growth potential while in the womb. In this blog, let us shed light on the causes, symptoms, and treatment options for IUGR, a condition that requires careful monitoring and medical management.

What are the Causes of IUGR?

Several factors can contribute to Intrauterine Growth Restriction, including:

  1. Placental Insufficiency: Insufficient blood flow or function of the placenta, which provides nutrients and oxygen to the fetus, can hamper fetal growth.
  2. Maternal Health Conditions:Chronic conditions such as hypertension, diabetes, kidney disease, and autoimmune disorders can impact fetal growth.
  3. Infections: Certain infections during pregnancy, such as cytomegalovirus (CMV) or Zika virus, can lead to IUGR.
  4. Genetic Factors: Inherited genetic abnormalities or chromosomal disorders may play a role in restricted fetal growth.
  5. Multiple Pregnancies:In pregnancies with twins or higher-order multiples, IUGR can occur due to competition for nutrients and space within the uterus.

What are the Symptoms of IUGR?

Detecting IUGR typically involves prenatal monitoring and ultrasound evaluations. Common symptoms and indicators include:

  • Small Fundal Height:The measurement of the uterus may be smaller than expected for the gestational age.
  • Decreased Fetal Movements:Reduced fetal movements or activity compared to normal patterns.
  • Low Birth Weight: Babies born with IUGR often have a birth weight below the 10th percentile for their gestational age.
  • Decreased Amniotic Fluid: A decrease in the volume of amniotic fluid (oligohydramnios) may be observed during ultrasound examinations.
  • Delayed Development:In severe cases, delayed development of organs or structures can be detected through ultrasound imaging.

What are the Treatment Options available for IUGR?

Managing IUGR requires a multidisciplinary approach involving obstetricians, perinatologists, and neonatologists. Treatment strategies may include:

  • Close Monitoring:Regular prenatal visits and ultrasound assessments to track fetal growth, amniotic fluid levels, and overall well-being.
  • Nutritional Support: Ensuring the mother receives adequate nutrition and hydration to support fetal growth.
  • Medical Interventions: Depending on the underlying cause and severity of IUGR, medical interventions such as medication or interventions to manage maternal health conditions may be necessary.
  • Fetal Surveillance:Monitoring fetal well-being through tests like Doppler ultrasound to assess blood flow in the umbilical artery and fetal heart rate monitoring.
  • Timely Delivery:In cases of severe or worsening IUGR, delivery may be recommended to prevent further complications.


Intrauterine Growth Restriction is a complex condition that requires careful evaluation, monitoring, and management throughout pregnancy. Understanding the causes, recognizing symptoms, and seeking timely medical intervention are crucial steps in optimizing outcomes for both the mother and the baby.
