Coffee, as one of the most popular beverages in the world, is known not only for its caffeine and increased alertness but also for its complex chemical compounds that can have unexpected effects on the human body. From its impact on the digestive system to changes in drug absorption, coffee can affect health in various ways.

Digestive Effects of Coffee

Studies show that nearly three out of ten people feel the urge to have a bowel movement after drinking coffee. This effect is not only related to caffeine but also stems from other compounds found in coffee. Additionally, coffee can increase large intestine activity in the morning, when most people drink their first cup of coffee. Factors such as lactose in milk or sugar-free sweeteners can also influence bowel movements.

Effects on Health and Medications

Coffee can exacerbate reflux symptoms in some individuals. This condition, where stomach acid flows back into the esophagus, can lead to coughing, wheezing, and other respiratory symptoms. Additionally, caffeine can increase intraocular pressure in some individuals with glaucoma, necessitating monitoring of eye pressure. Therefore, individuals with these issues may be advised to limit their coffee and caffeine intake.

Most medications are also somehow affected by coffee. For example, coffee can reduce the absorption of the thyroid medication levothyroxine and the osteoporosis drug alendronate. Furthermore, caffeine can slow the metabolism of the antipsychotic medication clozapine, increasing its concentration in the blood. Conversely, some medications, such as the antibiotic ciprofloxacin, can slow the breakdown of caffeine, so drinking coffee may have different effects when taking these medications.

Impact on Iron Absorption and Gut Microbiome

Coffee can also reduce iron absorption. Drinking coffee during meals can significantly decrease the absorption of non-heme iron. This effect is particularly important for individuals who rely on plant-based iron sources or have low iron stores. On the other hand, coffee contains compounds that can benefit the gut microbiome. Some chlorogenic acids in coffee reach the gut and are broken down by microbes, which can have positive effects on gut health.

Ultimately, coffee has complex effects on the body that go beyond caffeine. The multiple compounds present in coffee can interact with the digestive system, microbiome, medications, and nutrients, sometimes leading to unexpected outcomes. While coffee may be recognized as a popular beverage with known benefits, understanding its effects on health requires further investigation.
