Is it normal to develop a fever after a cesarean delivery?

Caesarean delivery—commonly referred to as C-section—refers to surgical delivery through an abdominal incision, while “fever” denotes elevated body temperature. In general, whether fever following a C-section is normal depends on whether other symptoms are present. If any discomfort or concerning symptoms arise, prompt medical evaluation is recommended. A detailed analysis follows:

A mild, transient low-grade fever shortly after a C-section—without other associated symptoms—is considered a normal physiological response during the postpartum period. Such fever is often attributable to “absorption fever,” resulting from the body’s absorption of fluid accumulated at the surgical site and tissue repair processes. Body temperature typically does not persistently rise and usually returns to baseline spontaneously within a short time, without impeding overall postpartum recovery.

Conversely, high-grade or persistent fever following a C-section—especially when accompanied by abdominal pain, foul-smelling lochia, wound erythema or discharge, dizziness, or fatigue—is abnormal. This type of fever commonly stems from complications such as surgical site infection, endometritis, or urinary tract infection. These conditions reflect active inflammatory pathology that will not resolve spontaneously and require timely medical evaluation to identify the underlying cause and initiate appropriate treatment.

After a C-section, it is advisable to monitor body temperature regularly, keep the abdominal incision clean and dry, and avoid water exposure to prevent infection. Adequate rest, balanced nutrition, and increased intake of warm water support metabolic function and healing. Additionally, closely observe the characteristics of lochia and wound healing; seek medical attention promptly if abnormal fever develops, thereby facilitating rapid and safe postpartum recovery.
