New Content Launched for Those Suffering from Constipation and Diarrhea, Aiming for the Ideal 'Banana Stool'

Bowel issues such as constipation and diarrhea are common yet difficult to discuss with others, often leading to prolonged discomfort due to self-prescribed remedies. In fact, a survey revealed that approximately 60% of people suffer from such irregularities.

Meanwhile, many individuals find that standard 'gut health' practices, such as consuming yogurt or fiber, do not yield noticeable improvements. This is because factors like diet, lifestyle, stress, and constitution vary, as do the state of the intestinal flora and stool type for each individual.

KEAN Health Co., Ltd. (Headquarters: Minato-ku, Tokyo; CEO: Keita Yamaji) will launch the new 'Constipation/Diarrhea Content' within its intestinal flora testing service 'chatFLORA G' starting April 27, 2026. This service presents tailored measures by combining stool condition with intestinal bacteria trends.

Through this service, the company aims to broaden opportunities for people to confront their bowel issues and make it easier to choose measures suited to them.

### Current State of Bowel Irregularities Upon launching this service, KEAN Health conducted an 'Abdominal Condition (Constipation/Diarrhea) Survey' among users of its services. The results showed that only 40.7% described their bowel movements as 'healthy.' The remaining 59.3% harbored some form of bowel concern: 31.1% were prone to constipation, 15.1% to diarrhea, and 13.1% experienced a cycle of both.

Concerns varied by gender as well. 61.1% of women reported bowel issues, exceeding the 54.3% reported by men. Notably, 'prone to constipation' stood out among women at 37.2%, while men showed a relatively high rate of 'prone to diarrhea' at 29.7%. This indicates that bowel concerns are a common challenge for many.

**Survey Details:** - Period: April 17, 2026 – April 24, 2026 - Method: Internet survey - Target: Users of KEAN Health's genetic and intestinal flora testing services - Valid Responses: 1,433

### Why Generic Gut Health is Often Ineffective Commonly known measures like 'fiber for constipation' or 'fermented foods for the gut' often fail to provide results. Bowel irregularities are linked to multiple factors including diet, stress, and constitution. Since gut flora and stool types are unique, generic measures often miss the mark.

To address this, KEAN Health developed new content that allows users to discover measures suited to them based on both stool condition and flora test results.

### Toward a World of Personalized Health Measures KEAN Health developed this service to help those who feel no change despite gut health efforts or don't know where to start. By supporting the entire journey—from understanding stool condition and bacteria trends to adopting suitable foods and habits—the company aims to contribute to improving bowel irregularities for many.
