Left upper abdominal pain?


Hello Doctor: Last October, I underwent an endoscopy which revealed a mild gastric ulcer and gastroesophageal reflux disease (GERD).
I was also diagnosed with Helicobacter pylori and completed the antibiotic treatment.
Currently, I am still taking a proton pump inhibitor (PPI) and have been on it for three months, with one month remaining.
However, in the past few days, I have experienced some pain in the upper left abdomen, slightly to the right of the rib cage, during dinner.
My diet has been normal, and I have not consumed any irritating foods.
I do not experience similar discomfort during breakfast or lunch; it only occurs during dinner.
The pain is present only while eating, not before or after meals.
What could be the possible cause of this?

Based on the symptoms, the likelihood of stomach pain is still the highest.
It is advisable to ask the physician to adjust the medication.
If there is still no improvement, an abdominal ultrasound examination is recommended.

Left upper abdominal pain can be a complex issue, especially when it arises after a history of gastrointestinal problems such as peptic ulcers and gastroesophageal reflux disease (GERD). Given your previous diagnosis of a mild gastric ulcer and the presence of Helicobacter pylori, it is essential to consider several potential causes for your current symptoms.

Firstly, the pain you are experiencing in the left upper abdomen, particularly after meals, could be related to your previous gastric ulcer. Even though you have completed the antibiotic treatment for H. pylori and are currently on a proton pump inhibitor (PPI), it is possible that the ulcer has not fully healed or that there is irritation in the gastric lining. Eating can stimulate gastric acid production, which may exacerbate any underlying irritation or inflammation, leading to discomfort during or after meals.

Another possibility is that your symptoms could be related to the esophagus or the lower part of the stomach. GERD can cause pain that mimics gastric discomfort, especially after eating. If the lower esophageal sphincter is not functioning properly, it can lead to acid reflux, which can cause pain in the upper abdomen and chest, particularly after meals.
Additionally, the timing of your pain—occurring specifically during dinner—could suggest a connection to the type or quantity of food consumed. If your dinner tends to be larger or richer than your other meals, this could lead to increased gastric pressure and discomfort. Foods that are high in fat or spices can also trigger symptoms in individuals with a history of gastritis or ulcers.

It is also worth considering the possibility of functional dyspepsia, a condition characterized by chronic or recurrent pain in the upper abdomen without an identifiable cause. This can occur even in individuals with a history of ulcers or GERD, and it may be exacerbated by stress or dietary choices.

Given that your pain is localized to the left upper abdomen and is associated with eating, it may also be prudent to rule out other gastrointestinal issues such as gastritis, pancreatitis, or even splenic issues, although these are less common. The fact that you do not experience pain at other times of the day, and that it is specifically linked to your evening meals, suggests that it may be more related to your digestive process rather than a serious underlying condition.

In light of your symptoms, it is advisable to consult with your gastroenterologist. They may recommend further evaluation, such as an upper gastrointestinal endoscopy, to assess the healing status of your ulcer and to check for any other potential issues. Additionally, they may suggest dietary modifications or adjustments to your medication regimen to better manage your symptoms.

In summary, while your left upper abdominal pain could be related to your previous gastric ulcer or GERD, it is essential to consider dietary factors, the timing of your symptoms, and the possibility of functional dyspepsia. A thorough evaluation by your healthcare provider will help in determining the exact cause and appropriate management for your condition.
