What causes aching pain with a sensation of heaviness in the lower abdomen?

Generally, "lower abdominal discomfort" refers to the lower abdomen. A sensation of heaviness or pain in the lower abdomen may be caused by factors such as the menstrual cycle, intense physical activity or fatigue, ovulation pain, acute appendicitis, uterine prolapse, and others. If discomfort occurs, it is recommended to seek medical attention promptly. Specific causes are analyzed as follows:

1. Menstrual Cycle

Prior to menstruation, hormonal changes in the body can cause pelvic congestion, leading to a feeling of heaviness and mild pain in the lower abdomen. Applying heat to the lower abdomen in daily life can improve blood circulation and help relieve pain.

2. Intense Exercise or Fatigue

After intense exercise or prolonged physical strain, the muscles and ligaments in the lower abdomen may become overstretched or fatigued, resulting in a sensation of abdominal heaviness and pain. It is important to reduce exercise intensity appropriately and avoid overexertion.

3. Ovulation Pain

During ovulation, the rupture of ovarian follicles and the release of follicular fluid can irritate the peritoneum, causing a sensation of heaviness and pain in the lower abdomen. Gentle physical activities such as walking or yoga may help alleviate symptoms.

4. Acute Appendicitis

Consuming spicy, greasy, or irritating foods may trigger acute appendicitis. The appendix is located in the lower right abdomen; when inflamed, it can cause pain in this area, often accompanied by a sensation of heaviness in the lower abdomen, nausea, vomiting, and fever. Under medical guidance, an appendectomy—complete removal of the appendix via laparoscopy—may be performed.

5. Uterine Prolapse

Weakening or damage to the uterine ligaments can lead to uterine prolapse, where the uterus descends toward the vaginal opening, causing a sensation of pressure and pain in the lower abdomen. This may be accompanied by symptoms such as lower back pain, frequent urination, and urgency. Pelvic floor muscle exercises, such as Kegel exercises, may be recommended under medical supervision to strengthen the supportive muscles through repeated contraction and relaxation.

In daily life, it is important to get adequate rest, avoid fatigue, maintain regular作息 (sleep-wake cycles), and perform appropriate pelvic floor muscle exercises such as Kegel exercises.
