It is very common to experience edema during ovulation, especially in women. Edema is caused by an imbalance in the water-salt balance within the body and usually manifests as local or systemic edema. During ovulation, the cause of edema can be due to many factors, including stress, hormone levels, diet, and sleep.

Stress is also a common factor in edema. During ovulation, a woman's hormone levels change dramatically, which can lead to increased stress within the body. If you feel stressed, you can relieve it with relaxation techniques such as meditation or deep breathing.

There are a few things you can do to reduce edema. For example, avoid eating too much salt, get enough sleep, exercise appropriately and reduce stress, etc. In addition, you can also consult a doctor for professional advice and treatment.

Although edema during ovulation is a common phenomenon, it doesn't necessarily mean it's normal. If the edema is too severe or lasts for too long, or is accompanied by other symptoms such as pain, fever, headache, etc., then you need to consult a doctor for examination and treatment.
