Most Common Cause of Intrauterine Fetal Growth Restriction

Many expectant mothers need to undergo regular follow-up examinations at the hospital during pregnancy, as directed by their healthcare provider, to monitor fetal development. What, then, is the most common cause of intrauterine growth restriction (IUGR)?

What is the most common cause of intrauterine growth restriction?

The most common cause of IUGR is maternal undernutrition or obesity. However, placental dysfunction cannot be ruled out as a contributing factor. Other potential causes include maternal systemic illnesses and genetic abnormalities.

When medication is required due to abnormal physical conditions, it must be taken strictly as prescribed by a physician. To achieve optimal therapeutic outcomes, it is also essential to adopt healthy dietary habits—such as eating smaller, more frequent meals—and avoid selective or imbalanced eating. Appropriate physical activity is likewise recommended. The primary principle in managing IUGR is to actively identify its underlying cause and treat any associated maternal condition. For instance, if IUGR results from pregnancy-induced hypertension, blood pressure control is mandatory.

Fetal anatomical ultrasound examination is recommended to rule out structural abnormalities. If indicated, fetal karyotyping may also be performed to assess for chromosomal disorders. Currently, no specific, universally effective treatment for IUGR exists in clinical practice. General supportive measures include adequate rest, routine oxygen supplementation, increased intake of high-protein foods, and, when necessary, low-molecular-weight heparin to improve placental circulation.
