6 common symptoms when suddenly stopping coffee consumption


If you’re a passionate coffee bean lover, you may experience 6 common symptoms when suddenly stopping coffee consumption.

6 common symptoms when suddenly stopping coffee consumption


After regularly consuming coffee for a long time, suddenly stopping caffeine intake can lead to the following conditions:


According to researchers from Johns Hopkins University and the University of Vermont (USA), headaches when stopping coffee consumption are caused by changes in blood flow to the brain. When consuming caffeinated beverages, blood vessels in the brain constrict, reducing blood flow. This blood flow increases when ceasing caffeine-containing beverages. The body may not adjust to this change quickly, leading to headaches.

Fatigue, lack of energy

6 common symptoms when suddenly stopping coffee consumption

Caffeine is a central nervous system stimulant that helps people increase their ability to concentrate. Many scientific studies have shown that supplementing with caffeine at both high and moderate doses can make users more alert. Therefore, suddenly reducing caffeine intake (especially when the body has become accustomed to it) can make you feel tired, sluggish, and sleepy.

Anxiety, irritability

Caffeine can increase dopamine levels in the brain. Therefore, when suddenly stopping coffee consumption, dopamine levels will also decrease, leading to feelings of dissatisfaction, anxiety, or irritability.

Difficulty concentrating

Several studies have shown that people who are sleep-deprived and supplement with caffeine can improve concentration and accuracy in their work. However, Dr. Eva Selhub advises us not to overuse caffeine to maintain concentration but rather to improve sleep quality.

Nausea and muscle fatigue

These are common symptoms of caffeine withdrawal. If they persist severely for an extended period, you should consult a doctor for advice on more effective caffeine withdrawal strategies.


Caffeine benefits the digestive system by increasing bowel motility. If the intestines are accustomed to being stimulated by caffeine, stopping consumption can lead to constipation.


Signs you should stop drinking coffee


6 common symptoms when suddenly stopping coffee consumption

Coffee is a beverage that is easily addictive because of its unforgettable taste. However, if you experience any of the following signs, you should stop drinking coffee to ensure your health.

High blood pressure

Coffee can increase blood pressure. Some studies have shown that consuming 200-300 mg of caffeine from coffee (equivalent to 1.5-2 cups) leads to an average increase of 8 mmHg and 6 mmHg in systolic and diastolic blood pressure, respectively. Many other investigation results also reflect that depending on genetics, the amount of coffee can either increase or not increase a person’s blood pressure. However, to ensure safety, individuals with high blood pressure should avoid coffee consumption.

Acid reflux

Caffeine can cause acid reflux symptoms by relaxing the lower esophageal sphincter. Consuming large amounts of caffeine can lead to diarrhea or even diarrhea in some people.

Sleep disorders

Usually, the feeling of drowsiness arises when a substance called adenosine accumulates in the brain. Caffeine directly blocks adenosine, reducing drowsiness after consumption. Drinking coffee within 6 hours or less before bedtime has disruptive effects on sleep.

Anxiety disorders

Caffeine can stimulate stress hormones. Therefore, individuals who often feel restless, easily irritable, or experience fatigue should avoid coffee.

Therefore, suddenly stopping coffee consumption can cause one of the above symptoms. These symptoms will typically subside after a short period (less than 1 month), so there is no need to worry excessively or consider coffee as an addictive substance.
