Why Does Nausea Occur During Ovulation?

The ovulation period is the phase following the follicular phase, which lasts about two weeks after menstruation begins. During ovulation, an egg is released from a follicle in the ovary. This period marks the transition from the low-temperature phase to the high-temperature phase in terms of basal body temperature. Changes in hormone levels specific to the ovulation period may contribute to feelings of nausea.

Hormonal Changes During Ovulation

Ovulation triggers a sudden change in hormone levels. Specifically, during the follicular phase following menstruation, estrogen (a hormone that thickens the uterine lining and lowers body temperature) increases, creating the low-temperature phase. Immediately after ovulation, progesterone levels increase to help maintain the uterine lining and raise body temperature, thus initiating the high-temperature phase.

Symptoms Triggered During Ovulation

Due to the rapid hormonal changes, the body can experience the following symptoms:

• Ovulation Pain

This pain occurs as the follicle ruptures and releases the egg, causing follicular fluid and blood to irritate the peritoneum. Although similar to menstrual cramps in terms of discomfort, it arises from a different mechanism. Ovulation pain is typically characterized by a pulling or tightening sensation on one side of the lower abdomen and may be accompanied by lower back pain.

• Ovulation Bleeding

When the follicle ruptures, a small amount of blood may be released, leading to ovulation bleeding. Unlike menstrual or abnormal bleeding, this bleeding is usually very light and lasts only 2-3 days.

Coping with Nausea During Ovulation

If you feel nauseous, try lying down in a comfortable position to relax. Gently massaging your abdomen can also help calm stomach activity. If you’re experiencing sleep deprivation, maintaining a regular sleep schedule for about a week can be beneficial.

For immediate relief, pressing the "Sanri" acupoint (located slightly below the knee) or the "Laogong" point (between the index and middle fingers on the palm) may help reduce nausea.

Additionally, eating slowly to avoid excess stomach acid production and choosing gentle foods can protect your stomach. Avoid overeating or consuming overly spicy foods.
