It is important to note that the degree of discomfort may vary among individuals, as some individuals may be more sensitive to the effects of caffeine or the acidity of espresso. If you experience stomach discomfort after consuming espresso, it may be helpful to adjust your intake or consider alternative beverages with lower acidity levels.
Gastrointestinal problems
In addition to stomach discomfort, excessive espresso consumption can contribute to gastrointestinal problems in the long term. The combination of caffeine and the acidity of espresso can lead to an increased production of stomach acid. Over time, this can potentially damage the lining of the stomach and contribute to the development of gastritis or ulcers.
Moreover, caffeine acts as a stimulant to the gastrointestinal tract, increasing motility and potentially causing diarrhea or loose stools. While this effect may be mild for most individuals, those with existing gastrointestinal conditions, such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), may be more susceptible to these adverse effects.
To minimize the risk of gastrointestinal problems, it is important to consume espresso in moderation and be mindful of your personal tolerance. If you have a history of digestive issues, it may be beneficial to consult with a healthcare professional about your espresso consumption and explore alternative beverages that are better tolerated by your gastrointestinal system.
Cardiovascular effects
Increased heart rate
The consumption of espresso, particularly due to its high caffeine content, can result in an increased heart rate. Caffeine is known to stimulate the central nervous system and trigger the release of adrenaline, a hormone that prepares the body for a “fight-or-flight” response. This can lead to a temporary increase in heart rate, making you feel more alert and energized.
While a slight increase in heart rate is usually well-tolerated by healthy individuals, it is important to consider individual differences and any underlying cardiovascular conditions. Individuals with cardiac arrhythmias, hypertension, or other heart-related conditions should exercise caution and consult with a healthcare professional before consuming espresso or any other caffeinated beverages.
Blood pressure changes
In addition to an increased heart rate, regular consumption of espresso can cause temporary elevations in blood pressure. This effect can be more pronounced in individuals who are more sensitive to the effects of caffeine.
