Introduction
Left lower abdominal pain may be caused by diseases of the descending colon and sigmoid colon. These include infectious inflammations in the descending and sigmoid colon due to various pathogens, such as bacterial dysentery, amoebic dysentery, and parasitic infections. Immune-mediated inflammations of the colon, such as ulcerative colitis, can also cause left lower abdominal pain. Additionally, colorectal tumors are a common cause of left lower abdominal pain.
As life pace gradually quickens, people are paying less and less attention to regular dietary and作息 habits. This can lead to various health problems, causing significant inconvenience in our daily lives. For example, lower left abdominal pain—what causes this discomfort?
What Causes Lower Left Abdominal Pain?
Lower left abdominal pain may be caused by diseases of the descending colon and sigmoid colon. Infections due to various pathogens in these areas—such as bacterial dysentery, amoebic dysentery, and parasitic infections—can trigger inflammatory responses. Immune-related inflammation in the descending and sigmoid colon, such as ulcerative colitis, can also result in lower left abdominal pain. Colon tumors are another common cause of pain in this region. Additionally, ischemic colitis frequently occurs in the descending and sigmoid colon, leading to lower left abdominal pain caused by colon disorders.
Lower left abdominal pain may also stem from urinary system disorders, such as urinary tract stones. Patients may experience severe pain in the left abdomen or lower left abdomen, especially during physical activity, often accompanied by back pain and hematuria (blood in urine). Moreover, in female patients, pelvic conditions are common causes of lower left abdominal pain, including pelvic inflammatory disease, adnexitis, ovarian cancer, and ovarian torsion. Additionally, extraperitoneal diseases—such as lumbar spine disorders, lumbar disc herniation, spinal tuberculosis, or tumors—can also manifest as lower left abdominal pain.
If you experience lower left abdominal pain, it is important to seek treatment early to prevent complications. You may visit a hospital's gynecology department for evaluation and care. We hope this information is helpful. Wishing you good health and happiness in life.
