Bowel movement issues


In the past two to three weeks, I have noticed that my bowel movements have become softer and somewhat light yellow in color.
There is no abdominal pain or other symptoms present, and I am unsure if there is any mucus, as I do not quite understand what mucus in stool means.
Typically, I have a bowel movement in the morning after breakfast, and occasionally in the evening as well.
Recently, I have been feeling that my bowel movements are not completely satisfying, and sometimes when I wipe after a particularly forceful bowel movement, there is a bit of blood.

I wonder if this is related to overeating during the New Year celebrations.
About two weeks ago, I started exercising to lose weight and began eating an orange after my workouts.
I noticed the strange bowel movements around that time.
This week, after exercising, I switched from eating an orange to toast, but my bowel movements still seem to be soft.

I have heard that colorectal cancer can cause changes in bowel habits and a feeling of incomplete evacuation.
I have lost about 0.9 kg since I started exercising two weeks ago, which seems to be a normal rate of weight loss.
Although the likelihood of developing colorectal cancer at my age is low, I am still somewhat concerned due to some reported cases.
What could these symptoms indicate? Thank you!

Hello: There is no need to worry too much; this should still be considered a normal phenomenon.
If you still have concerns, you can consult a gastroenterologist or a colorectal specialist to investigate the occasional presence of blood in your stool.

More Info


Changes in bowel habits can often be concerning, especially when they deviate from what is considered normal for an individual. In your case, you've noted that your stool has become softer and lighter in color over the past few weeks, and you are experiencing a sensation of incomplete evacuation. Additionally, you mentioned some minor bleeding when wiping after a bowel movement, which can understandably heighten your anxiety about potential serious conditions such as colorectal cancer.

Firstly, it's important to define what constitutes a change in bowel habits. Generally, this refers to any significant alteration in the frequency, consistency, or appearance of stools compared to your baseline. For instance, if you typically have well-formed stools and suddenly experience persistent diarrhea or very soft stools, this would be considered a change. The Bristol Stool Chart is a useful tool for categorizing stool consistency, ranging from type 1 (hard lumps) to type 7 (watery, no solid pieces). You mentioned your stools have become softer, which may indicate a shift towards types 5 or 6 on this chart.

The presence of mucus in the stool can also be a point of concern. Mucus is a normal component of stool, as it helps to lubricate the intestines. However, an increase in mucus, especially if accompanied by changes in stool consistency or color, can sometimes indicate underlying gastrointestinal issues, such as irritable bowel syndrome (IBS) or infections. In your case, since you are unsure about the presence of mucus, it may be beneficial to monitor your stools more closely.

Your recent dietary changes and increased physical activity could also be contributing factors to your altered bowel habits. A sudden increase in fiber intake, especially from fruits like oranges, can lead to changes in stool consistency. If your diet has shifted significantly, it may take some time for your digestive system to adjust. Additionally, stress and anxiety can have profound effects on gut health, potentially leading to symptoms like diarrhea or a feeling of incomplete evacuation.

Regarding your concerns about colorectal cancer, it is true that changes in bowel habits can be a symptom. However, it is essential to consider the context. Colorectal cancer typically presents with more severe symptoms, such as significant weight loss, persistent abdominal pain, blood in the stool, or changes that last for more than a few weeks. Given your age and the fact that you have recently started exercising and eating differently, it is more likely that your symptoms are related to dietary changes or stress rather than a serious condition.

The minor bleeding you mentioned could be due to several factors, including hemorrhoids, anal fissures, or irritation from wiping too hard. If the bleeding persists or worsens, it would be prudent to consult a healthcare professional for a thorough evaluation.

In summary, while your symptoms warrant attention, they are not necessarily indicative of a serious condition like colorectal cancer, especially given your age and recent lifestyle changes. It would be wise to continue monitoring your symptoms, maintain a balanced diet, and ensure adequate hydration. If your symptoms persist or worsen, or if you develop new symptoms, seeking medical advice would be the best course of action. Regular check-ups and open communication with your healthcare provider can help alleviate your concerns and ensure your gastrointestinal health is monitored effectively.
