When Strong Tea Becomes Harmful

According to the doctor, tea can be problematic when it replaces water as the primary source of daily fluid intake. The risk increases significantly if a person drinks strong tea on an empty stomach.

"Strong tea contains a higher concentration of tannins — natural compounds that can slow gastrointestinal motility while simultaneously stimulating the secretion of hydrochloric acid,” the doctor explained.

This combination can irritate the stomach lining. For people with erosive or ulcerative changes in the stomach, such stimulation may provoke a worsening of symptoms or trigger a relapse.

Impact on Digestion and Iron Absorption

Beyond its effect on the digestive system, strong tea can interfere with the body's ability to absorb iron from food. This is particularly relevant for individuals suffering from iron deficiency.

"People with iron-deficiency anemia should limit tea consumption or at least avoid drinking it immediately after meals — it is better to wait two or three hours,” the gastroenterologist advised.

Tannins bind iron in the digestive tract, reducing its absorption and potentially worsening anemia over time if the habit persists.

Moderation Is Key

Medical experts emphasize that tea itself is not harmful when consumed in moderation. Problems arise primarily from excessive strength, frequent intake, and inappropriate timing, especially on an empty stomach.

Balancing tea consumption with adequate water intake and mindful timing can help preserve its benefits while avoiding unnecessary strain on the digestive system.
