Post-meal abdominal discomfort can be a common issue and may arise from various causes. Given your description of experiencing a dull pain around the navel approximately 30 minutes after eating, it is essential to consider several potential factors that could contribute to this discomfort.

One of the most common causes of post-meal abdominal pain is related to digestive processes. After eating, the body directs blood flow to the digestive tract to aid in the breakdown and absorption of food. This can sometimes lead to sensations of discomfort, especially if the meal was large or high in fat, which can slow down digestion. Conditions such as gastritis, peptic ulcers, or even food intolerances (like lactose intolerance or gluten sensitivity) could also manifest as discomfort after meals.

Another possibility is that the pain could be related to the gallbladder, especially since you mentioned having had gallbladder surgery. After cholecystectomy (gallbladder removal), some individuals experience a condition known as postcholecystectomy syndrome, which can include symptoms like abdominal pain, bloating, and changes in bowel habits. This is due to the changes in bile flow and digestion without the gallbladder's storage function.
Additionally, while it is less common, conditions such as irritable bowel syndrome (IBS) or functional dyspepsia could also lead to post-meal discomfort. IBS is characterized by a combination of abdominal pain and altered bowel habits, while functional dyspepsia involves discomfort in the upper abdomen, often related to eating.

Regarding your concerns about appendicitis or cancer, it is important to note that appendicitis typically presents with more acute and severe pain, often starting around the navel and then moving to the lower right abdomen, accompanied by other symptoms such as fever, nausea, or vomiting. Cancer, particularly gastrointestinal cancers, usually presents with a more complex array of symptoms, including significant weight loss, changes in appetite, persistent abdominal pain, or changes in bowel habits over time.
Given that your bowel movements are normal and the pain is not severe, it is less likely that you are experiencing appendicitis or cancer at this point. However, it is crucial to monitor your symptoms. If the pain persists, worsens, or is accompanied by other concerning symptoms (like significant weight loss, persistent vomiting, or changes in bowel habits), it would be advisable to seek medical evaluation.

In conclusion, while post-meal abdominal discomfort can arise from various benign causes, it is essential to remain vigilant about your symptoms. If your discomfort continues or worsens, consider consulting a healthcare professional for a thorough evaluation, which may include a physical examination, imaging studies, or laboratory tests to rule out any underlying conditions. Regular follow-ups and open communication with your healthcare provider can help ensure that any potential issues are addressed promptly.
