Coffee is often consumed as a solution to eliminate drowsiness and increase concentration. However, there are some side effects of coffee that you need to be aware of, especially if you over-consume it.
Various studies have proven the benefits of coffee for the body, ranging from improving mood and metabolism to lowering the risk of cardiovascular disease, type 2 diabetes, Parkinson’s disease, gout, and cancer.
If consumed in the appropriate amount, i.e. no more than 2–3 cups per day, coffee is generally safe for adults and does not harm health. However, side effects of coffee can appear if the coffee is consumed in excess amounts, which is more than 4 cups of coffee per day.
Various Side Effects of Coffee
Consuming too much or consuming too much caffeine can eventually lead to side effects called caffeinism. In general, coffee side effects that often occur include:
Caffeine can keep you awake, overcome sleepiness, and increase concentration. However, excessive caffeine intake can reduce sleep time and make the body unable to sleep well. This can make you experience sleep disorders, such as insomnia.
2. Frequent urination
Increased frequency of urination is a common side effect of coffee. Coffee contains caffeine that is diuretic so it can stimulate urine discharge and make you urinate more often. This is what makes you go to the toilet more often after consuming coffee.
Caffeine can indeed increase alertness because it has a stimulant effect. However, the side effects of coffee can also make you become restless and anxious. This effect can even cause panic attacks and relapse symptoms of anxiety disorders.
4. Heart rate becomes fast
Drinking too much coffee can also cause the heart to beat faster and the rhythm of the heartbeat to change (atrial fibrillation). If you experience this after drinking coffee, consider reducing your coffee intake.
Do you become more frequent in defecation after consuming coffee? If so, this is due to the laxative effect on coffee. Side effects of this coffee can make the intestines become more active, so that the movement of the intestine becomes faster.
Not only that, excessive coffee consumption can also cause other side effects, such as diarrhea, stomach ulcers, and relapse of GERD disease.
6. Caffeine withdrawal
Caffeine withdrawal is a side effect of coffee that appears when a person is used to regularly drinking coffee, then suddenly stop taking it.
When experiencing the side effects of this coffee, you can feel headaches, dizziness, nausea, fatigue, difficulty concentrating, until the mood changes quickly.
In addition to the above conditions, drinking too much coffee in the long run can also cause other side effects, such as high blood pressure and rhabdomyolysis.
Who Should Reduce or Avoid Coffee?
Not everyone is safe to consume coffee. Therefore, you should limit or even avoid coffee if you experience certain conditions or diseases, such as:
- Mental disorders, such as anxiety disorders, bipolar disorder, or depression
- Indigestion, including stomach acid disease or GERD and irritable bowel syndrome
- Uric acid
- Consumption of certain medications, such as antibiotics, antidepressants, or asthma medications
In addition to some of the above conditions, pregnant women are also recommended to limit coffee consumption because it can increase the risk of miscarriage, premature birth, and low baby birth weight.
Nursing mothers are also advised to reduce coffee. This is because caffeine content can be absorbed into breast milk, so babies who are breast-fed can become more fussy, sleepless, and at risk of colic.
Side effects of coffee usually appear when a person consumes a large amount of coffee or in the long run. However, in people who are sensitive to caffeine, coffee side effects can appear even if they consume only a small amount of coffee.
