Possible Causes of Abdominal Pain and Loss Of Appetite

Conditions that commonly cause both symptoms together

1Early Gastritis often produces non-specific symptoms: fatigue, malaise, or mild discomfort
2Early warning signs may include: abdominal pain, nausea, vomiting, loss of appetite
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 Gastritis
5Screening programmes are designed specifically to detect Gastritis before symptoms appear
6Core management targets: reducing abdominal pain, nausea, vomiting and preventing disease progression

Emergency Red Flags

Seek immediate medical attention if you experience any of these

Any of the characteristic symptoms of Gastritis — 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 Gastritis combined with new relevant symptoms

When to See a Doctor

Schedule a medical consultation if you notice these signs

You have risk factors for Gastritis 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 Gastritis

Scheduled monitoring appointments — do not skip even when feeling well

Conditions That Cause Both Abdominal Pain and Loss Of Appetite

9 conditions are associated with this symptom combination

Gastritis is inflammation of the stomach lining, commonly caused by H. pylori infection, prolonged NSAID use, or excessive alcohol. It can be acute (sudden) or chronic (long-term) and may lead to peptic ulcers if untreated.

Peptic ulcers are open sores that develop on the inner lining of the stomach or the upper part of the small intestine. H. pylori infection and long-term NSAID use are the most common causes. They cause burning stomach pain, especially when the stomach is empty.

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.

Pancreatitis is inflammation of the pancreas, which can be acute (sudden) or chronic (long-term). Gallstones and heavy alcohol use are the most common causes. It causes severe upper abdominal pain that may radiate to the back, nausea, and vomiting.

Gallstones are hardened deposits of digestive fluid that form in the gallbladder. They can range from sand-grain size to golf-ball size. Many are asymptomatic, but when they block a duct they cause severe 'biliary colic' pain in the upper right abdomen.

Appendicitis is inflammation of the appendix causing progressive right lower quadrant abdominal pain, nausea, fever, and rebound tenderness. Perforation risk increases with delayed treatment; surgical removal (appendectomy) is standard care.

Enterobiasis (Pinworm Infection)

Enterobiasis is the most common helminthic infection in temperate countries, caused by Enterobius vermicularis. It predominantly affects children and presents with intense nocturnal perianal itching. Treatment is with mebendazole or albendazole.

Taeniasis (Tapeworm Infection)

Taeniasis is intestinal infection by Taenia solium or Taenia saginata tapeworms, acquired by eating undercooked pork or beef. Symptoms include abdominal discomfort and weight loss. Neurocysticercosis (T. solium larvae in the CNS) is the most severe complication. Praziquantel is curative.
