A C-section itself doesn't directly trigger psoriatic arthritis (PsA), but it can affect psoriasis symptoms in an indirect way.
During a C-section, the skin is cut and injured. For people with psoriasis, this kind of skin trauma can trigger something called the Koebner phenomenon — where new psoriasis patches appear on areas of skin that have been injured or traumatized. It's also worth knowing that PsA symptoms in general can worsen after giving birth, regardless of delivery method. Research shows that:
- 33% to 50% of people reported more severe arthritis symptoms after delivery
- 27% to 34% reported more severe psoriasis symptoms after birth
- Flare-ups are possible for up to six months postpartum
These changes are thought to be linked to hormonal shifts, fatigue, and medication adjustments during and after pregnancy.
It's really important to keep your rheumatologist and obstetrician closely in the loop before, during, and after delivery so they can help manage any flares or changes in symptoms.
