1. Gastritis and Gastric Ulcers

Gastritis and gastric ulcers are conditions that compromise the stomach mucosa, causing inflammation and damage to the inner lining. These conditions can cause symptoms such as heartburn, abdominal pain, and digestive discomfort.

Reason for the Prohibition

Coffee contains substances such as caffeine and chlorogenic acids, which stimulate the secretion of hydrochloric acid in the stomach. This increased acidity can irritate the already inflamed gastric mucosa, worsening the symptoms of heartburn and pain. Furthermore, this effect can interfere with ulcer healing, prolonging recovery time and increasing the risk of complications.

People with gastritis or ulcers should avoid both caffeinated and decaffeinated coffee, as both contain acidic compounds.

Opt for mild infusions such as chamomile tea, which has anti-inflammatory and soothing properties, or oat water, known for being gentle on the digestive system.

Maintaining a balanced diet that avoids irritating foods such as fried foods, spicy foods, and citrus fruits can also help reduce symptoms.

2. Sleep Disorders

Sleep disorders, such as insomnia and sleep apnea, affect the quality of a night’s rest and can negatively impact overall health. The relationship between coffee consumption and these conditions is significant due to caffeine’s stimulant effects.

Reason for the Prohibition

Caffeine works by blocking adenosine receptors, a chemical that induces relaxation and promotes sleep. Consuming coffee, especially near nighttime, can make it difficult to fall asleep, reduce sleep depth, and disrupt the normal sleep cycle. This is particularly problematic for those who already suffer from insomnia or have difficulty achieving restful sleep.

Recommendations

Avoiding coffee completely or limiting its intake to the early hours of the day can be very helpful.

Replacing coffee with relaxing alternatives such as valerian, passionflower, or linden teas, which promote calmness and encourage sound sleep.

Establishing a sleep hygiene routine, which includes avoiding electronic devices before bed, can also improve outcomes.

3. Cardiac Arrhythmias

Cardiac arrhythmias are disturbances in the heart’s normal rhythm that can manifest as palpitations, tachycardia, or irregular heartbeats. This type of condition can be exacerbated by coffee consumption due to caffeine’s effects on the cardiovascular system.

Reason for the Prohibition

Caffeine has a direct impact on heart rate, as it can increase beats per minute and trigger episodes of tachycardia in susceptible individuals. Furthermore, its stimulating action on the sympathetic nervous system can intensify arrhythmias, causing discomfort and, in some cases, serious health risks.
