Changes in Bowel Movements: From Formed to Diarrhea - Gastroenterology and Hepatology

Formed stool at the front followed by diarrhea at the end?


Hello, doctor.
During my midterm exam today, I suddenly experienced intermittent cramping in my abdomen.
I hurriedly submitted my exam and went to the restroom.
At first, I had to exert some effort to pass my stool, but then it turned into a more diarrhea-like consistency.
However, after I finished, the abdominal pain subsided, and there was no pain during the bowel movement.
Should I consider this a change in bowel habits that requires further examination?

Hello: If it is just an occasional occurrence, there is no need to worry excessively; it may be influenced by irritating foods or mental stress.
If there is a persistent change in bowel habits compared to the past, you should consult a gastroenterologist.

Changes in bowel movements can be concerning, especially when they deviate from what is considered normal for an individual. In your case, experiencing a sudden onset of abdominal pain followed by a change in stool consistency—from formed stools to a more diarrhea-like state—raises several considerations.

Firstly, it’s important to understand that bowel habits can be influenced by a variety of factors, including diet, stress, hydration levels, and underlying gastrointestinal conditions. The Bristol Stool Scale categorizes stool into seven types, with types 3 and 4 being considered ideal. Your description suggests a transition from a more formed stool to a looser consistency, which could indicate a temporary change in your digestive process.

The acute abdominal pain you experienced during your exam could be attributed to several factors. Stress and anxiety, particularly in high-pressure situations like exams, can significantly affect gastrointestinal function. This is often referred to as "nervous stomach" or functional gastrointestinal disorder, where stress leads to increased gut motility and can result in diarrhea.
Additionally, dietary changes or the consumption of certain foods prior to your exam could also contribute to this change. Foods that are high in fat, spicy, or contain lactose (if you are intolerant) can lead to gastrointestinal upset. If you have recently altered your diet, this could be a significant factor in your symptoms.

Given that your abdominal pain resolved after a bowel movement and you did not experience pain during the act of defecation, this suggests that the pain was likely related to the buildup of gas or stool in the intestines rather than a structural issue. The fact that you were able to pass stool without discomfort afterward is a positive sign.

However, it is essential to monitor your symptoms closely. If you continue to experience changes in your bowel habits, such as persistent diarrhea, abdominal pain, or any other concerning symptoms (like blood in your stool, significant weight loss, or prolonged changes in appetite), it would be advisable to seek further evaluation from a healthcare professional.
In terms of diagnostic steps, if your symptoms persist or worsen, a gastroenterologist may recommend tests such as stool studies to check for infections or inflammatory markers, and possibly imaging studies or a colonoscopy if there are concerns about structural abnormalities or conditions like inflammatory bowel disease (IBD) or colorectal cancer, especially if you have risk factors or a family history.

In summary, while your current symptoms may not immediately warrant extensive testing, it is crucial to remain vigilant about any ongoing changes in your bowel habits. Stress management techniques, dietary adjustments, and maintaining hydration can be beneficial in managing your symptoms. If your condition does not improve or if new symptoms arise, do not hesitate to consult a healthcare provider for a thorough assessment.
