Medical Expert Warns: Black Stools May Indicate Serious Health Issues

Dr. Jetsada Bunyawongviroj, Deputy Director of Primary Care at Maharat Nakhon Ratchasima Hospital, has issued a public health advisory regarding the significance of black-colored stools. While many people immediately attribute dark stool to dietary intake—such as consuming iron supplements, blood-based foods, or dark-colored ingredients—Dr. Jetsada warns that this assumption can be dangerous if the underlying cause is internal.

According to the expert, individuals should be particularly concerned if the stool appears pitch-black, sticky, shiny like asphalt, and carries an unusually foul odor. These specific characteristics may indicate 'melena,' a condition caused by bleeding in the upper gastrointestinal tract, such as the stomach or the duodenum. In such cases, blood is digested as it travels through the digestive system, resulting in the dark coloration.

For residents and travelers in Thailand, this information serves as a reminder to monitor physical health symptoms closely. Dr. Jetsada emphasizes that one should not simply wait for the condition to resolve on its own. Instead, it is essential to evaluate the stool's color, texture, and odor, while also considering recent dietary habits and medication use. If these warning signs are present, seeking professional medical evaluation is recommended. It remains to be confirmed whether these symptoms are linked to specific dietary patterns or underlying medical conditions in individual cases.
