During the exams people drink tea or coffee for focused and alert minds. For most people, the right amount of caffeine can help with focus; too much might hurt digestion, sleep and even your overall health — all of which may drag down academic performance rather than lift it up.

It's exam season, and although it is stressful time for everyone, some students are determined to study at their desk with as little rest as possible! To stave off exhaustion and stay focused, tea and coffee are natural bedfellows. One cup here and one there seems harmless enough, but as caffeine consumption spikes, the body reacts in unexpected ways. Digestion is one of the most frequently impacted.

Caffeine is a stimulant that stimulates the nervous system and prompts acid production in the stomach. Smaller amounts may act as a tonic to stimulate alertness; but too much—with or without food—irritates the lining of the digestive tract. How many of you find yourself admitting that during exams you suffer from symptoms like acidity, bloating, nausea, stomach cramps or irregular bowel movements while not being able to put your finger on the reason for why all this is happening to you? Caffeine over consumption, along with irregular meals and sleep, can slow gut health and may have you feeling far from your best.

Dr. Ashwin Chatterjee, Consultant Gastroenterologist at IPES Healthcare Kolkata, says people abuse caffeine for exam related reasons more frequently now. “Students are often over-caffeinated beyond what their body can manage. This what makes its way to the gut can lead to uncomfortable fullness and reduced energy while also disturbing digestion, nutrient absorption, and movements of the bowels,” he explains.

The Effects of Too Much Tea and Coffee on Digestion

Gastric Acid and Acidity

Caffeine is known to boost stomach acid production. Over-consumption can cause irritation to the lining of the stomach and even promote gastrointestinal disorders such as heartburn, gastritis, and acid reflux. You are more likely to experience burning and indigestion when consuming several cups of tea or coffee, especially on an empty stomach!

Disrupted Gut Movement

In addition, caffeine can accelerate the movement of the intestines and lead to loose stools or an immediate need for a bathroom break. It could cause children constipation as well, in some kids by dehydration. This imbalance in gut motility is a source of discomfort, cramps and unpredictable digestion during exams.

Reduced Nutrient Absorption

Compounds in tea and coffee also block the absorption of crucial nutrients such as iron, calcium and magnesium. Overindulging at exam time could lead to fatigue, weakness and inability to concentrate the opposite effect that students may be hoping for.

Increasing Bodily Discomfort

Anecdotes aside, exam stress is already known to hit the gut-brain axis. Excessive consumption of caffeine also amplifies stress hormones (cortisol), making acidity, irritate bowel syndrome (IBS) and nausea worse. This leads to a vicious cycle of anxiety and digestion issues that hits your performance.
