Intrauterine growth restriction is a health condition where a growing fetus is smaller than he or she is supposed to be. There are many causes of growth restriction including infections and maternal health conditions. Growth restriction impacts about 10% of the population in developed countries, but up to about 30% in developing countries.


Babies with growth restriction are more likely to have low blood sugar and jaundice after they are born. These babies go on to have other health conditions later in life, including difficulties with learning, obesity, high blood pressure, and diabetes. 

More information about growth restriction can be found on the Tiny But Mighty Baby website.

There is no cure for intrauterine growth restriction. However, the goal of the Tiny But Mighty Baby Foundation is to help support research into improving the lives of people with growth restriction. 

Dr. Zinkhan wrote the book, Tiny But Mighty Baby: A Parents' Guide to Navigating Your Child's Diagnosis of Intrauterine Growth Restriction to help empower, inform, and engage families in the care of their tiny but mighty babies (available now in paperback and Kindle).
