There are many health benefits of coffee as we mentioned earlier, but there are negative results as well.
Health effects of coffee
Drinking a lot of coffee can also have some harmful effects. In the sections below, we cover some of these risks:
1. It can cause bone fractures
Some studies have found that women who drink a lot of coffee may have a higher risk of bone fractures.
On the other hand, men who drink more coffee seem to have a slightly lower risk.

2. It can be dangerous during pregnancy
The researchers added that coffee may not be safe during pregnancy. In fact, there is some evidence to suggest a link between higher coffee consumption and pregnancy loss, low birth weight and premature birth (s).
3. It can be dangerous to the endometrium
There may be a higher risk of endometriosis among coffee drinkers, but there isn't enough evidence to confirm this association.
4. It can cause gastroesophageal reflux disease
People who drink a lot of coffee may be more likely to develop this condition.
5. It can cause anxiety
Consuming large amounts of caffeine may increase the risk of anxiety, especially among people with panic disorder or social anxiety disorder.
Less commonly, it may lead to mania and psychosis in susceptible people (s).
6. It can affect mental health
One study from 2016 concluded that high caffeine intake during adolescence can lead to permanent changes in the brain.
The scientists who conducted the study expressed concern that this may increase the risk of developing anxiety-related conditions in adulthood (s).

Summary
A meta-analysis from 2017 concluded that it is "generally safe" for most people to consume three to four cups of coffee per day, and that doing so may actually reduce the risk of some health conditions (s).
However, the study authors cautioned that smoking may cancel out any benefits of drinking coffee.
Caffeine is an important characteristic of coffee, but coffee contains many compounds, and there are different ways to drink it.
This makes it difficult to determine exactly how coffee affects a person and which ingredients have benefits and risks.
A person who wants to get health benefits from coffee should avoid exceeding the recommended daily intake and try to monitor the ingredients they add, such as sugar, cream or flavorings, as they may not be healthy.
