Expert Advice: What to Do About Persistent Diarrhoea

A 63-year-old man experiencing persistent diarrhoea for three weeks has raised concerns about his health after his symptoms worsened, accompanied by blood. Despite taking over-the-counter medications, he seeks guidance from medical professionals to understand the seriousness of his condition.

According to Dr. Zoe Williams, a specialist and NHS GP, there are several critical factors to consider in this situation. The presence of blood in the stool and the duration of diarrhoea merit a thorough medical evaluation. Dr. Williams emphasizes that any changes in bowel habits, especially in individuals over 60, should be taken seriously, even if the bleeding appears minor.

Diarrhoea that lasts more than four weeks is a cause for concern and requires further investigation. While the symptoms might stem from less serious issues such as irritated haemorrhoids or an anal tear due to diarrhoea, the potential for more severe conditions cannot be ruled out. Possible underlying causes include bowel infections, inflammatory bowel disease, bowel ischemia (reduced blood flow), diverticulitis, bowel polyps, or even cancer.

For those experiencing similar symptoms, Dr. Williams advises against self-medication with anti-diarrhoea tablets unless directed by a healthcare professional. Such medications can sometimes exacerbate underlying problems. Instead, staying hydrated is crucial. Patients should drink plenty of fluids and avoid alcohol, spicy foods, and non-steroidal anti-inflammatory drugs like ibuprofen.

While it is natural to feel anxious about persistent gastrointestinal symptoms, Dr. Williams reassures patients that seeking medical attention is the right course of action. Proper assessment is essential to determine the underlying issue and to establish an appropriate treatment plan.

In summary, if you or someone you know is experiencing prolonged diarrhoea with additional symptoms such as blood, it is vital to consult a healthcare provider promptly. Early intervention can lead to better outcomes and peace of mind.
