Symptom Combination

Diarrhea and Nausea: Causes, Conditions & When to See a Doctor

Early recognition of Endometriosis is critical — treatment initiated at the earliest stage is significantly more effective and prevents long-term complications. Understanding the subtle initial presentations allows patients and clinicians to act before the condition progresses.

Possible Causes of Diarrhea and Nausea

Conditions that commonly cause both symptoms together

  1. 1Early Endometriosis often produces non-specific symptoms: fatigue, malaise, or mild discomfort
  2. 2Early warning signs may include: abdominal pain, fatigue, back pain, nausea
  3. 3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
  4. 4Family history and risk factors increase the probability that vague symptoms represent early Endometriosis
  5. 5Screening programmes are designed specifically to detect Endometriosis before symptoms appear
  6. 6Core management targets: reducing abdominal pain, fatigue, back pain and preventing disease progression

Emergency Red Flags

Seek immediate medical attention if you experience any of these

Any of the characteristic symptoms of Endometriosis — even mild — in a high-risk individual
Progressive worsening of early warning signs over weeks
Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
Strong family history of Endometriosis combined with new relevant symptoms

When to See a Doctor

Schedule a medical consultation if you notice these signs

You have risk factors for Endometriosis and develop any of the characteristic early symptoms
Screening tests return borderline or abnormal results
You have a strong family history and have not yet been screened for Endometriosis
Scheduled monitoring appointments — do not skip even when feeling well

Conditions That Cause Both Diarrhea and Nausea

15 conditions are associated with this symptom combination

Endometriosis
Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus. It causes chronic pelvic pain, especially during menstruation, and can lead to infertility. It affects approximately 10% of reproductive-age women.
Typhoid Fever
Typhoid fever is caused by Salmonella typhi, transmitted through contaminated food and water, causing sustained fever, abdominal pain, and rose spots. Antibiotic treatment is effective; vaccination is recommended for travellers to endemic areas.
Norovirus (Stomach Flu)
Norovirus is the leading cause of acute gastroenteritis worldwide, spreading through contaminated food, water, and surfaces. It causes sudden-onset vomiting, diarrhea, and stomach cramps lasting 1-3 days; hydration is the mainstay of treatment.
Salmonellosis
Salmonellosis is a foodborne illness caused by Salmonella bacteria, typically from contaminated poultry, eggs, or raw produce. Symptoms include diarrhea, fever, and abdominal cramps beginning 6-48 hours after exposure; most resolve within a week.
Celiac Disease
Celiac disease is an autoimmune reaction to gluten that damages the small intestine villi, impairing nutrient absorption. Symptoms include diarrhea, bloating, weight loss, and fatigue; strict gluten-free diet is the only treatment.
Diverticulitis
Diverticulitis occurs when diverticula (small pouches in the colon wall) become inflamed or infected, causing left lower quadrant pain, fever, and bowel changes. Uncomplicated cases are treated with antibiotics; perforation or abscess may require surgery.
SIBO (Small Intestinal Bacterial Overgrowth)
SIBO occurs when excessive bacteria colonize the small intestine, causing bloating, abdominal pain, diarrhea, and malabsorption. It is diagnosed with breath testing and treated with antibiotics and dietary modification.
Dumping Syndrome
Dumping syndrome occurs after gastric surgery when food moves too quickly from the stomach into the small intestine, causing nausea, diarrhea, sweating, and dizziness after meals. Dietary modifications and slower eating are primary management strategies.
