Two hormones injected immediately after a C-section can prevent a lifetime of obesity and brain dysfunction caused by skipping a natural birth.
Oxytocin and vasopressin administered to newborns replace the hormonal surge that normally occurs during a trip through the birth canal. Babies born via C-section often face a higher risk of weight gain and dopamine issues later in life. These hormones act as a biological trigger that sets the metabolic and neurological systems on the correct path. This simple pharmacological rescue stops the development of hypoactivity and excess weight in offspring. It provides a straightforward way to give C-section babies the same chemical head start as those born naturally. This intervention could mitigate long-term health risks for millions of children globally.
Oxytocin and Vasopressin at Birth Prevent Hypoactivity and Excess Weight Gain in Vole Offspring Delivered by Cesarean Section

Birth occurs during a sensitive period in brain development wherein hormones facilitate the dramatic shift in physiology that accomplishes the transition to extrauterine homeostasis. The surge in birth signaling hormones is abridged in cases of delivery by cesarean section (CS), which accounts for 32% of all births in the U.S. Epidemiological studies have associated birth via CS with increased risk of obesity in later life. Here, we sought to investigate this association using an experimental pr
