What Causes Pain on the Left side of the Stomach?

Pain on the left side of the stomach can be caused by various underlying conditions and organs located in that area. It’s essential to consider the specific location and nature of the pain to help determine the possible cause. Some common causes of left-sided abdominal pain include:

  • Gas and indigestion: Gas trapped in the digestive system or indigestion can cause discomfort and pain on the left side of the abdomen.
  • Gastrointestinal issues: Conditions like gastritis (inflammation of the stomach lining), peptic ulcers, or irritable bowel syndrome (IBS) can cause left-sided abdominal pain.
  • Constipation: Difficulty passing stools or constipation can lead to pain and discomfort on the left side of the stomach.
  • Diverticulitis: Inflammation or infection of small pouches in the colon (diverticula) can cause left-sided abdominal pain, fever, and changes in bowel movements.
  • Kidney stones: If a kidney stone becomes lodged in the left ureter (the tube that connects the kidney to the bladder), it can cause severe left-sided abdominal pain, often radiating to the back.
  • Ovarian issues: In women, problems with the left ovary, such as ovarian cysts or ovarian torsion, can cause left-sided lower abdominal pain.
  • Splenic issues: The spleen is located on the left side of the abdomen, and problems such as an enlarged spleen, infection, or injury can lead to left-sided pain.
  • Muscle strain: Strained or pulled muscles in the abdomen can cause localized pain on the left side.
  • Pancreatitis: Inflammation of the pancreas can cause pain in the upper left abdomen.
  • Left-sided hernia: Hernias in the abdominal wall on the left side can cause discomfort and pain.
  • Infections: Various infections, such as urinary tract infections or pelvic inflammatory disease (in women), can cause left-sided abdominal pain.
  • Ectopic pregnancy: In pregnant women, an ectopic pregnancy (when the fertilized egg implants outside the uterus, usually in the fallopian tube) can cause left-sided abdominal pain and may be life-threatening if not treated promptly.

It is important to seek medical attention if you experience severe or persistent left-sided abdominal pain, especially if it is accompanied by other symptoms such as fever, vomiting, blood in the stool or urine, or changes in bowel habits. A healthcare professional can perform a physical examination, order relevant tests, and make a proper diagnosis to address the underlying cause of the pain. Self-diagnosis based on internet information is not recommended, as it may lead to incorrect assumptions or delayed treatment.
