Causes of hiatus<unk>  vary depending on each individual. Among the multiple causes, however, are the mechanical causes which include: improper heavy weight lifting, hard coughing bouts, sharp blows to the abdomen, and incorrect posture. Furthermore, conditions that increase the pressure of the abdominal cavity may also cause<unk> s or worsen the existing ones. Some examples would be: obesity, straining during a bowel movement or urination (constipation, enlarged prostate), chronic lung disease, and also, fluid in the abdominal cavity (ascites). Also, if muscles are weakened due to poor nutrition, smoking, and overexertion,<unk> s are more likely to occur. The physiological school of thought contends that in the case of inguinal<unk> , the above-mentioned are only an anatomical symptom of the underlying physiological cause. They contend that the risk of<unk>  is due to a physiological difference between patients who suffer<unk>  and those who do not, namely the presence of aponeurotic extensions from the transversus abdominis aponeurotic arch. Abdominal wall<unk>  may occur due to trauma. If this type of<unk>  is due to blunt trauma it is an emergency condition and could be associated with various solid organs and hollow viscus injuries.
