Causes of left abdominal pain in males can include testicular torsion, a gastrointestinal infection or Crohn’s disease, according to Healthgrades. Another cause of such pain is acute pancreatitis, a medical condition that occurs when the pancreas becomes inflamed, notes MedlinePlus.
Acute pancreatitis is commonly caused by excessive alcohol use and gallstones, explains MedlinePlus. Other causes of acute pancreatitis include viral infections, medications, hyperparathyroidism and Kawasaki disease. The pain associated with the condition is felt in the middle or upper left side of the abdomen and gets worse after eating or when lying on the back. Patients with acute pancreatitis typically look ill and have symptoms such as fever, vomiting and nausea.
Testicular torsion occurs when the spermatic cord that supports the testes becomes twisted, according to MedlinePlus. The condition causes the blood supply to the testicles to become cut off, resulting in symptoms such as severe testicular pain, vomiting, lightheadedness, scrotal swelling and blood in the semen. Testicular torsion is caused by defects or injury to the scrotum.
Crohn's disease is chronic intestinal inflammation and ulceration, notes Cleveland Clinic. Doctors do not know what causes the condition, which often leads to complications such as blockages in the bowel, malabsorption and abnormal passageways within the bowel and nearby tissues. Patients with Crohn's disease experience symptoms such as fever, weight loss, chronic diarrhea and abdominal pain and tenderness.
