Introduction
A foul odor in lochia after cesarean delivery is typically caused by infection or prolonged lochia. Postpartum lochia with an abnormal odor may result from inflammatory responses triggered by persistent lochia and bacterial infection. Some women with conditions such as vaginitis, cervicitis, endometritis, cervical cancer, or precancerous cervical lesions may experience foul-smelling lochia.
After cesarean delivery, lochia is an issue every woman must confront. Some women may experience cessation of lochia within as little as 20 days, while others continue to have it beyond this period. If an unpleasant odor accompanies the lochia at this stage, many women become anxious. What causes foul-smelling lochia following cesarean delivery?
What Causes Foul-Smelling Lochia After Cesarean Delivery?
Foul-smelling lochia after cesarean delivery is typically attributable to infection or prolonged lochia. Postpartum foul-smelling lochia may result from persistent lochia combined with bacterial infection, leading to an inflammatory response. Women suffering from conditions such as vaginitis, cervicitis, endometritis, cervical cancer, or precancerous cervical lesions may also present with foul-smelling lochia.
In addition to a fishy odor, if the maternal surgical wound exhibits signs such as redness, swelling, pain, or purulent discharge, incisional infection should be suspected. For mild symptoms, local application of iodophor for disinfection may be attempted, followed by observation for improvement. If no improvement occurs—or if symptoms worsen—prompt medical evaluation and possible wound debridement with secondary suturing are required. Commonly prescribed antibiotics include penicillin. In cases of pronounced foul odor, timely evaluation at a reputable hospital is essential, along with active cooperation with the physician’s treatment plan.
Generally, dietary recommendations following cesarean delivery emphasize light, low-sodium meals. During the first week postpartum, it is advisable to consume millet porridge and eggs, and moderately drink crucian carp soup—these foods may enhance lactation. However, consumption of brown sugar and milk should be avoided, as they may cause indigestion and abdominal distension. We hope this information proves helpful!
