Differential Diagnosis for Lower Bilateral Abdominal Pain, Nausea, Fatigue, Fever, and Gas
Single Most Likely Diagnosis
- Diverticulitis: This condition is characterized by inflammation of the diverticula in the colon, which can cause lower abdominal pain, nausea, fatigue, fever, and changes in bowel habits. The presence of fever and abdominal pain, particularly if localized to the lower left side, makes diverticulitis a strong consideration.
Other Likely Diagnoses
- Gastroenteritis: Inflammation of the stomach and intestines, often due to viral or bacterial infection, can cause nausea, vomiting, diarrhea, abdominal pain, and fever. The symptoms provided could align with a severe case of gastroenteritis.
- Urinary Tract Infection (UTI): UTIs can cause lower abdominal pain, fever, nausea, and fatigue. The pain is often localized to the suprapubic area but can radiate to the lower abdomen.
- Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can present with chronic or acute abdominal pain, diarrhea, weight loss, fatigue, and sometimes fever. The mention of "mulberry fruit" is unclear but could potentially refer to a change in stool appearance, which might be seen in IBD.
Do Not Miss Diagnoses
- Appendicitis: Although appendicitis typically presents with right lower quadrant pain, it can sometimes cause more diffuse or bilateral pain, especially if the appendix is retrocecal. Missing appendicitis can lead to perforation and severe complications.
- Ectopic Pregnancy: In women of childbearing age, ectopic pregnancy is a critical diagnosis to consider with abdominal pain and can present with nausea, vomiting, and fever. It's a life-threatening condition if not promptly diagnosed and treated.
- Ovarian Torsion: This is another emergency condition that can cause severe lower abdominal pain, nausea, and vomiting. It occurs when the ovary twists around its ligaments, cutting off blood supply.
Rare Diagnoses
- Intestinal Obstruction: This condition involves a blockage of the intestine, which can cause severe abdominal pain, nausea, vomiting, and constipation. While it's less common, it's a serious condition requiring prompt medical attention.
- Endometriosis: In women, endometriosis can cause chronic pelvic pain, nausea, and fatigue, especially during menstruation. It's less likely to cause acute fever but should be considered in the differential for chronic symptoms.
- Mesenteric Lymphadenitis: Inflammation of the lymph nodes in the mesentery can mimic appendicitis or other causes of abdominal pain. It's more common in children and young adults.
