Which of the following are signs of potential complications during the third trimester?

Severe headaches during the third trimester can be indicative of potential complications, such as hypertension or preeclampsia. In a pregnant patient, especially in the latter stages, the presence of a severe headache that is new or different from typical headaches can signal an underlying issue that requires evaluation. Preeclampsia, characterized by elevated blood pressure and potential organ dysfunction, can manifest with headaches, changes in vision, and other symptoms. Recognizing severe headache as a sign of potential complications is crucial for ensuring timely medical intervention and improving maternal and fetal outcomes.

In contrast, increased appetite commonly occurs as the body requires more nutrition to support the growing fetus and does not generally indicate a complication. Normal swelling of the ankles can be a common and expected physiological change in late pregnancy, often related to fluid retention. Fluctuating weight can happen due to various factors, including fluid changes, but does not necessarily indicate a complication unless accompanied by other concerning symptoms.
