Consequences of overeating?


Hello Doctor, on the evening of the 18th, I ate too much cold noodles, which caused discomfort in my stomach.
The next morning, I experienced severe diarrhea, but afterwards, the volume of my stools decreased, and I also had a slight loss of appetite.
Prior to this, my stools were usually large and formed.
I visited a doctor yesterday, and they diagnosed me with gastroenteritis.
After taking medication, I felt somewhat better, but the stool volume is still low.
I would like to know if it is advisable to undergo an endoscopy in this situation (I had a mild gastric ulcer a year ago) or if I should continue to monitor my condition.
Also, is it normal for my stools to turn black or dark green if I eat spinach and sweet potato leaves at every meal?

1.
There is no need for an endoscopy; you can gradually increase your intake of fruits and vegetables.

2.
It is caused by the pigments in leafy greens, so there is no need to worry.

More Info


Overeating can lead to a variety of gastrointestinal symptoms, and your experience seems to align with common aftereffects of consuming excessive amounts of food, particularly rich or heavy meals. When you mentioned that you had a significant amount of cold noodles, it’s important to recognize that large meals can overwhelm the digestive system, leading to symptoms such as abdominal discomfort, diarrhea, and changes in bowel habits.

The symptoms you described, including severe diarrhea the following morning and a subsequent decrease in stool volume, suggest that your gastrointestinal tract was reacting to the overload. This reaction can be due to several factors, including irritation of the intestinal lining, changes in gut motility, and alterations in the gut microbiome. Diarrhea is often a protective mechanism that helps the body expel irritants or pathogens, and in your case, it seems to have been triggered by the overeating episode.

Regarding your question about whether to undergo an endoscopy (gastroscopy), it is essential to consider your previous medical history, including the mild gastric ulcer you experienced a year ago. If your symptoms persist or worsen, or if you experience additional concerning symptoms such as significant abdominal pain, blood in your stool, or persistent vomiting, it would be prudent to consult your healthcare provider about the necessity of further investigation, including an endoscopy. This procedure can help visualize the upper gastrointestinal tract and assess for any abnormalities, including ulcers or inflammation that may have developed since your last examination.

As for the changes in your stool color after consuming spinach and sweet potato leaves, it is quite normal for certain foods to affect stool color. Dark green or black stools can result from the consumption of leafy greens, as they are rich in chlorophyll, which can impart a green hue to your stool. Additionally, sweet potatoes can also contribute to darker stool due to their high fiber content and natural pigments. However, if you notice a persistent change in stool color that is not related to dietary changes, or if you experience other symptoms such as abdominal pain or discomfort, it is advisable to seek medical attention.

In summary, while your symptoms may be a result of overeating and subsequent gastrointestinal irritation, it is crucial to monitor your condition closely. If your symptoms improve with medication and dietary adjustments, you may not need an endoscopy immediately. However, if you experience any alarming symptoms or if your condition does not improve, do not hesitate to consult your healthcare provider for further evaluation. Maintaining a balanced diet, avoiding overeating, and being mindful of food choices can significantly contribute to better gastrointestinal health.
