Differential Diagnosis for Left Side Abdominal Pain
- Single most likely diagnosis
- Constipation: The patient is experiencing abdominal pain but is still able to open their bowels, which suggests that the pain may be related to constipation or hard stools. The pain level is relatively low (2/10), which is consistent with constipation.
- Other Likely diagnoses
- Irritable Bowel Syndrome (IBS): IBS can cause abdominal pain, bloating, and changes in bowel habits. The fact that the patient is still able to open their bowels suggests that the pain may be related to IBS.
- Diverticulitis: Diverticulitis is an inflammation of the diverticula in the colon, which can cause abdominal pain, usually on the left side. However, the pain is typically more severe than 2/10.
- Gastroenteritis: Gastroenteritis is an inflammation of the stomach and intestines, which can cause abdominal pain, diarrhea, and vomiting. The fact that the patient is still able to open their bowels suggests that the pain may be related to gastroenteritis.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Appendicitis: Although the pain is on the left side, appendicitis typically presents with pain on the right side, it's possible for the appendix to be located on the left side (situated retrocecal or near the left pelvic wall). Appendicitis is a medical emergency that requires prompt surgical attention.
- Intestinal obstruction: An intestinal obstruction can cause severe abdominal pain, vomiting, and constipation. If the obstruction is not relieved, it can lead to tissue death and perforation.
- Ectopic pregnancy: An ectopic pregnancy is a life-threatening condition that occurs when a fertilized egg implants outside the uterus. It can cause abdominal pain, vaginal bleeding, and other symptoms.
- Rare diagnoses
- Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis): These conditions can cause chronic abdominal pain, diarrhea, and weight loss. However, they are less common than other diagnoses on this list.
- Colon cancer: Colon cancer can cause abdominal pain, changes in bowel habits, and weight loss. However, it is relatively rare, especially in younger patients.
- Ovarian torsion: Ovarian torsion is a rare condition that occurs when the ovary twists around its ligaments, cutting off blood supply. It can cause severe abdominal pain and is a medical emergency.
