Why Does Right Lower Abdominal Pain Occur During Menstruation?

During menstruation, women may experience pain in the right lower abdomen due to various physiological and pathological factors. Understanding these causes can help identify whether the discomfort is normal or requires medical attention.

Pelvic Congestion or Blood Stagnation: One of the most common reasons for right-sided abdominal pain during your period is pelvic congestion. During menstruation, increased blood flow to the pelvic region can cause localized swelling and pressure, which may lead to pain on one side—often the right.

Inflammation of the Reproductive Organs: Conditions such as pelvic inflammatory disease (PID) or inflammation of the right fallopian tube or ovary can flare up during menstruation. These conditions often result in sharp or persistent pain on the right side of the lower abdomen.

Exposure to Cold or Chills: During your menstrual cycle, the body's immune system may be temporarily weakened due to blood loss and hormonal fluctuations. Exposure to cold temperatures or drafts can trigger muscle contractions and cramping, particularly on one side of the abdomen.

Underlying Medical Conditions: In some cases, right lower quadrant pain may not be related to menstruation at all. Conditions like cystitis (bladder infection), urethritis, or kidney stones affecting the right ureter can become more noticeable or worsen during menstruation due to increased pelvic pressure and sensitivity.

If the pain is severe, persistent, or accompanied by other symptoms such as fever, nausea, or abnormal bleeding, it's important to consult a healthcare provider to rule out any serious underlying issues.
