Abdominal pain after eating without diarrhea?


Two years ago, I went to the hospital for a colonoscopy due to oily food causing rectal bleeding.
At that time, there was inflammation in the intestines, but no polyps were found.
After taking medication and following a light diet for a few weeks, my condition improved.
About a month ago, I suspected another episode of intestinal inflammation after consuming oily food again.
The symptoms were similar: after eating, I experienced diarrhea that relieved the pain, with stool being wet and sticky, mixed with some clear liquid.
I thought that eating lighter foods, like toast, would help, but after two to three days without a bowel movement, eating chicken breast caused a recurrence.
I went to the hospital, and the doctor ordered a stool test and prescribed a five-day course of antibiotics.
After starting the medication, I stopped having diarrhea, but I experienced a dull pain in my abdomen, located about three to four fingerbreadths below my navel.
I completed the medication on time, and the stool test results were normal, showing no occult blood, viruses, or parasites, and the appearance was normal with neutral fat staining below 60 HPF, which is considered normal.

The doctor mentioned that since I wasn't experiencing diarrhea, there wasn't much concern.
However, it has now been over two weeks, and whenever I eat beef, chicken breast, or salmon, I experience dull abdominal pain, but I do not have diarrhea.
Eating shrimp or egg whites does not cause this discomfort.
Therefore, I mostly eat whole grain toast, apples, egg whites, shrimp, and tilapia.
My stool shape is generally normal, though it occasionally becomes soft, seemingly after experiencing the dull pain.
What could these symptoms indicate? Will I have to avoid red meat and chicken breast in the future? Thank you!

It is likely a functional disorder; it is recommended to consume low-fat, low-dairy, and non-irritating foods.

Post-meal abdominal pain without diarrhea can be a perplexing symptom, especially when you have a history of gastrointestinal issues. Given your previous experience with intestinal inflammation and the recent symptoms you've described, it’s important to consider several potential causes and management strategies.

Firstly, it is crucial to understand that the gastrointestinal tract can react to various foods differently, particularly after a history of inflammation. Your symptoms of abdominal discomfort after consuming certain proteins like beef, chicken breast, and salmon, while tolerating shrimp and eggs, suggest that there may be a food intolerance or sensitivity at play. This could be due to the way your body processes these specific proteins, especially if your gut lining has been compromised in the past.

One possible explanation for your symptoms is the concept of "postprandial distress syndrome," which refers to discomfort after eating, often linked to the type of food consumed. Fatty or rich foods can exacerbate symptoms in individuals with a history of gastrointestinal issues. Since you mentioned that your symptoms improved with a lighter diet, it may be beneficial to continue avoiding high-fat or heavily processed foods.

Another consideration is the possibility of a condition known as "functional dyspepsia," which can cause discomfort in the upper abdomen after meals, without any identifiable organic cause. This condition can be exacerbated by anxiety, stress, or dietary choices, leading to symptoms like bloating, fullness, and pain.

Given that your stool tests returned normal and you have no signs of infection or parasites, it seems that your gastrointestinal system is functioning adequately in terms of digestion and absorption. However, the recurring pain suggests that your body may still be reacting negatively to certain foods. It’s worth noting that some individuals develop sensitivities to foods they previously tolerated, especially after episodes of gastrointestinal distress.

To manage your symptoms, consider the following strategies:
1. Dietary Modifications: Since you’ve identified that certain foods trigger your symptoms, it may be wise to avoid red meat and chicken breast for the time being. Instead, focus on lean proteins that you tolerate well, such as fish and shrimp, and incorporate more plant-based proteins like legumes and tofu.

2. Food Diary: Keeping a food diary can help you track what you eat and how it affects your symptoms. This can provide valuable insights into which foods to avoid and help you identify patterns in your digestive health.

3. Gradual Reintroduction: If you wish to test your tolerance to certain foods, consider a gradual reintroduction approach. Start with small amounts of the food in question and monitor your symptoms closely.

4. Consultation with a Specialist: If your symptoms persist or worsen, it may be beneficial to consult with a gastroenterologist or a dietitian specializing in gastrointestinal disorders. They can provide tailored advice and may suggest further testing, such as an endoscopy or imaging studies, to rule out any underlying conditions.

5. Stress Management: Since anxiety can exacerbate gastrointestinal symptoms, incorporating stress-reduction techniques such as mindfulness, yoga, or cognitive behavioral therapy may also be beneficial.

In conclusion, while your symptoms may be frustrating, they can often be managed through dietary adjustments and careful monitoring. It’s important to listen to your body and seek professional guidance if needed, ensuring that you maintain a balanced diet that supports your overall health.
