Lower abdominal pain refers to discomfort or pain specifically in the lower part of the abdomen. Several common causes of lower abdominal pain include: - Diverticulitis: Inflammation or infection of small pouches in the intestinal walls. - Gas: Buildup of gas in the abdomen, leading to pressure, burping, and passing gas. - Lactose intolerance: Inability to fully digest lactose, a sugar found in dairy products. - Celiac disease: An immune reaction to gluten, a protein found in wheat, barley, and rye. - IBD (Crohn's disease or ulcerative colitis): Chronic inflammation of the digestive tract. - Indigestion: Rarely causes lower abdominal pain, but can occur as a result of acid buildup after eating. - IBS (irritable bowel syndrome): A common disorder affecting the large intestine. - Constipation: Difficulty or inability to pass stool. - Hernia: When a body part or organ pushes through the abdominal wall. - Bowel obstruction: Blockage preventing the passage of digested material through the bowel. - Appendicitis: Inflammation of the appendix, causing dull pain that moves to the lower right abdomen and becomes sharper. - Stomach flu: Intestinal infection characterised by cramping, nausea, and fever. These are some of the common causes of lower abdominal pain. It's important to consult with a healthcare professional to determine the exact cause and receive appropriate treatment.
