Abdominal Pain and Fatigue: Causes, Conditions & When to See a Doctor

Early recognition of Colitis (Ulcerative Colitis) 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 Abdominal Pain and Fatigue

Conditions that commonly cause both symptoms together

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

Emergency Red Flags

Seek immediate medical attention if you experience any of these

Any of the characteristic symptoms of Colitis (Ulcerative Colitis) — 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 Colitis (Ulcerative Colitis) combined with new relevant symptoms

When to See a Doctor

Schedule a medical consultation if you notice these signs

You have risk factors for Colitis (Ulcerative Colitis) 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 Colitis (Ulcerative Colitis)

Scheduled monitoring appointments — do not skip even when feeling well

Conditions That Cause Both Abdominal Pain and Fatigue

30 conditions are associated with this symptom combination

Colitis (Ulcerative Colitis)

Ulcerative colitis is a chronic inflammatory bowel disease causing long-lasting inflammation and ulcers in the digestive tract, primarily affecting the colon and rectum. It leads to abdominal pain, diarrhea with blood, and urgency.

Hepatitis is inflammation of the liver, most commonly caused by viral infections (Hepatitis A, B, C, D, E). It can also result from alcohol use, toxins, or autoimmune conditions. Symptoms include jaundice, fatigue, abdominal pain, and dark urine.

Liver Cirrhosis

Liver cirrhosis is advanced scarring (fibrosis) of the liver caused by long-term damage from hepatitis, alcohol abuse, or fatty liver disease. As scar tissue replaces healthy tissue, the liver loses its ability to function properly.

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.

PCOS (Polycystic Ovary Syndrome)

Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age, causing irregular periods, excess androgen levels, and polycystic ovaries. It is associated with insulin resistance and increased risk of diabetes and heart disease.

Colorectal Cancer

Colorectal cancer develops in the colon or rectum and is the third most common cancer globally. Risk factors include age over 50, family history, inflammatory bowel disease, and diet high in red/processed meat.

Liver Cancer (Hepatocellular Carcinoma)

Hepatocellular carcinoma typically develops in the setting of chronic liver disease or cirrhosis due to hepatitis B, hepatitis C, or alcohol. It is a leading cause of cancer death globally.

Pancreatic Cancer

Pancreatic cancer has one of the lowest survival rates of all cancers, largely due to late-stage diagnosis. Symptoms include jaundice, weight loss, abdominal pain, and new-onset diabetes; most cases are adenocarcinomas.
