Abdominal pain can be a complex symptom with a wide range of potential causes, particularly in the field of gastroenterology. Your symptoms of abdominal pain, nausea, weight loss, and decreased appetite, without diarrhea, can indicate several underlying conditions that warrant further investigation.

One of the primary concerns with your symptoms is the possibility of gastrointestinal disorders. Conditions such as gastritis, peptic ulcers, or even gastroesophageal reflux disease (GERD) could lead to the symptoms you are experiencing. Gastritis, which is the inflammation of the stomach lining, can cause pain and nausea, particularly after eating. Peptic ulcers, which are sores that develop on the lining of the stomach or the first part of the small intestine, can also lead to similar symptoms, including weight loss due to decreased appetite.

Another potential cause could be a more serious condition, such as a malignancy. Weight loss and decreased appetite can be red flags for gastrointestinal cancers, including stomach or pancreatic cancer. These conditions often present with nonspecific symptoms, making early detection challenging. Therefore, it is crucial to consider these possibilities, especially if your symptoms persist or worsen.

Additionally, conditions affecting the liver or gallbladder, such as hepatitis or gallstones, could also lead to abdominal pain and nausea. Gallstones can cause intense pain, particularly after meals, and can lead to complications if they obstruct the bile duct. Hepatitis, an inflammation of the liver, can also present with nausea and weight loss.

In some cases, functional gastrointestinal disorders, such as irritable bowel syndrome (IBS), may also be a consideration. IBS can cause abdominal pain and changes in bowel habits, but it typically includes diarrhea or constipation, which you have not mentioned. However, stress and psychological factors can exacerbate gastrointestinal symptoms, so it is essential to consider the whole person when evaluating these symptoms.

Given the range of potential causes, it is important to seek medical attention for a thorough evaluation. A healthcare provider may recommend a series of diagnostic tests, including blood tests, imaging studies (such as an ultrasound or CT scan), and possibly an endoscopy, to visualize the gastrointestinal tract and identify any abnormalities.

In summary, your symptoms of abdominal pain, nausea, weight loss, and decreased appetite without diarrhea could be indicative of several gastrointestinal conditions, ranging from gastritis and peptic ulcers to more serious concerns like malignancies or liver disease. It is essential to consult with a healthcare professional for a comprehensive evaluation and appropriate management. Early diagnosis and treatment can significantly improve outcomes and alleviate symptoms.
