Differential Diagnosis for Left Side Abdominal Pain
Single Most Likely Diagnosis
- Constipation: The patient's complaint of left side abdominal pain and difficulty opening bowels (constipation) suggests a possible issue with bowel movements, which is a common cause of abdominal pain. The pain level of 2/10 is relatively mild, which is consistent with constipation.
Other Likely Diagnoses
- Irritable Bowel Syndrome (IBS): IBS can cause abdominal pain, changes in bowel habits, and difficulty opening bowels. The left side abdominal pain could be related to the sigmoid colon, which is commonly affected in IBS.
- Diverticulitis: Diverticulitis is an inflammation of the diverticula in the colon, which can cause left side abdominal pain, especially if the diverticula are located in the sigmoid colon.
- Gastroesophageal Reflux Disease (GERD): Although GERD typically causes upper abdominal pain, it can also cause referred pain to the left side of the abdomen.
Do Not Miss Diagnoses
- Appendicitis: Although appendicitis typically causes right lower quadrant pain, it can occasionally cause left side abdominal pain if the appendix is located in an unusual position (e.g., retrocecal appendix).
- Ectopic Pregnancy: In women of childbearing age, ectopic pregnancy can cause left side abdominal pain and should be considered, especially if there is a history of missed periods or vaginal bleeding.
- Ovarian Torsion: Ovarian torsion can cause severe left side abdominal pain and is a medical emergency that requires prompt attention.
- Intestinal Obstruction: Intestinal obstruction can cause abdominal pain, nausea, vomiting, and difficulty opening bowels. It is a serious condition that requires prompt medical attention.
Rare Diagnoses
- Inflammatory Bowel Disease (IBD): IBD, such as Crohn's disease or ulcerative colitis, can cause left side abdominal pain, but it is less common than other causes of abdominal pain.
- Colon Cancer: Colon cancer can cause left side abdominal pain, especially if the tumor is located in the sigmoid colon. However, it is a rare cause of abdominal pain in younger individuals.
- Splenic Infarction: Splenic infarction can cause left upper quadrant pain, but it is a rare condition that typically occurs in individuals with underlying splenic disease or trauma.
