Nigerian doctor and health educator, Chukwuma Okoro, popularly known as Aproko Doctor, has warned Nigerians about the potential health risks of using untreated borehole water to rinse their mouths.

Aproko Doctor issued the warning on Monday in a video shared on X, where he raised concerns about possible contamination of borehole water and its potential link to Helicobacter pylori(H. pylori), a bacterium associated with peptic ulcers.

He explained that borehole water could become contaminated, particularly where water sources are poorly protected or located close to soakaway systems and other sources of contamination.

According to the doctor, exposure to contaminated water may increase the risk of ingesting harmful microorganisms, including H. pylori.

He consequently advised Nigerians to ensure that water from boreholes is properly treated before use, including when it is intended for brushing or rinsing the mouth.

Aproko Doctor also warned against the frequent or inappropriate use of painkillers such as ibuprofen and diclofenac, which belong to a group of medicines known as non-steroidal anti-inflammatory drugs and have been associated with peptic ulcers.

He urged Nigerians experiencing persistent stomach pain or other symptoms suggestive of an ulcer to seek medical attention rather than relying on self-medication.

The doctor further advised people to take black or tarry stool seriously, as it can be a sign of bleeding in the digestive tract and requires prompt medical evaluation.

H. pylori infection is recognised as a major cause of peptic ulcers. Health authorities also identify contaminated food and water as possible routes through which the bacterium can spread.

Aproko Doctor’s warning therefore highlights the importance of ensuring that borehole water is safe and properly treated before it is used for drinking or oral hygiene.
