Reduced abdominal wall strength and increased intra-abdominal pressure are the main causes of inguinal hernia. Reduced strength of the abdominal wall leads to weak points in the abdominal wall. Certain congenital channels in the abdominal wall of the human body, such as the spermatic cord or the round ligament of the uterus, pass through the inguinal canal where they are weak, and under the action of prolonged high intra-abdominal pressure, inguinal hernias are gradually generated. Continuous or instantaneous elevation of intra-abdominal pressure is the causative factor for the generation of inguinal hernia. Chronic cough, chronic constipation, difficulty in urination such as bladder stones, prostatic hypertrophy, and heavy physical labor can induce the occurrence of inguinal hernia. Inguinal hernia can cause serious complications, such as incarcerated hernia can cause intestinal strangulation, endangering the patient’s life. If you find an unexplained lump in the groin area, you should immediately go to the general surgery department of your local hospital, complete the examination, make a clear diagnosis and follow the doctor’s instructions for treatment.
