Persistent watery stools?


Hello, doctor.
For the past month, I have been experiencing consistently unformed stools that are yellowish-brown in color, without any blood present.
The doctor has determined that my colon is quite sensitive.
During the medication period, my condition improved (but I only have a bowel movement every two to three days, and they are formed).
After stopping the medication, my symptoms gradually returned to their original state.
I typically have unformed stools at most once a day, often occurring after breakfast, and the abdominal pain subsides after bowel movements.
Previously, I also experienced hard stool at the beginning and loose stool at the end.
Could you please tell me if the above symptoms are typical of irritable bowel syndrome?

Hello: 1.
Irritable Bowel Syndrome (IBS) is a periodic and recurrent issue, but it is essential to rule out any organic problems.
2.
The diagnostic criteria require that within the past 12 months, the patient has experienced abdominal discomfort for at least 12 weeks (or more than 12 weeks) with recurrent symptoms including: ■ Abdominal pain or bloating that improves after a bowel movement ■ Changes in bowel frequency, such as constipation (fewer than 3 times a week) or diarrhea (more than 3 times a day) ■ Changes in stool form (hard lumps, loose stools, or watery stools) ■ Changes in bowel habits (straining, urgency, or feeling of incomplete evacuation) ■ Presence of mucus in the stool or passing mucus-like stools.

More Info


Based on the symptoms you've described, it does seem that you may be experiencing Irritable Bowel Syndrome (IBS), particularly the subtype characterized by diarrhea (IBS-D). IBS is a functional gastrointestinal disorder that affects the large intestine and is characterized by a combination of symptoms, including abdominal pain, bloating, and changes in bowel habits, such as diarrhea or constipation.

Your report of persistent loose stools that are yellowish-brown, along with the absence of blood, aligns with common IBS symptoms. The fact that your condition improves with medication but then returns to a less favorable state suggests a chronic, recurring nature typical of IBS. The abdominal pain you experience that alleviates after a bowel movement is also a hallmark symptom of IBS.

IBS can be triggered by various factors, including dietary choices, stress, and changes in routine. Given that you mentioned your symptoms often occur after breakfast, it may be worth considering whether specific foods are contributing to your symptoms. Common triggers include dairy products, high-fat foods, and certain carbohydrates known as FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols). Keeping a food diary to track your meals and symptoms may help identify any correlations.

Additionally, the fact that you experience a mix of stool types—sometimes hard at the beginning and loose at the end—further supports the diagnosis of IBS. This pattern can occur in IBS patients, where the stool consistency varies due to the irregular contractions of the intestines.

It’s also important to consider the role of stress and anxiety in your symptoms. IBS is often exacerbated by psychological factors, and many individuals with IBS report that their symptoms worsen during periods of increased stress. Since you mentioned experiencing anxiety, addressing this aspect through stress management techniques, therapy, or medication may also be beneficial.

In terms of management, dietary modifications are often the first line of treatment for IBS. A low-FODMAP diet has been shown to be effective for many individuals with IBS. This diet involves reducing the intake of certain carbohydrates that can ferment in the gut and cause symptoms. Additionally, regular physical activity and adequate hydration can help improve bowel function.

Medications may also play a role in managing IBS symptoms. Antispasmodics can help relieve abdominal pain, while certain medications can target diarrhea or constipation specifically. Since you mentioned that your condition improved with medication, it may be worth discussing with your healthcare provider whether a different medication or dosage might provide more consistent relief.

Lastly, if your symptoms persist or worsen, or if you develop new symptoms such as weight loss, severe abdominal pain, or changes in appetite, it is crucial to follow up with your healthcare provider. They may recommend further evaluation, such as additional testing or referrals to specialists, to rule out other conditions that could mimic IBS.

In summary, your symptoms are consistent with IBS, particularly the diarrhea-predominant type. A combination of dietary changes, stress management, and possibly medication adjustments may help you achieve better control over your symptoms. Always consult with your healthcare provider before making significant changes to your treatment plan.
