Five diseases caused by drinking too much coffee

We could say that the caffeine It is the most widely consumed legal drug in the world, almost always in the form of coffee: one of the reasons for this is the effect it has on the brain that makes us feel more alert.

Although a moderate dose of caffeine is not harmful, as in the consumption of anything, if we overdo it we can have health problems.


We drink coffee to wake up in the morning just to feel more alert when we wake up, or at night if we don’t want to fall asleep before finishing some work.

The stimulating effect of caffeine has to do with blocking the adenosine, a neurotransmitter, which influences the states of drowsiness.

Too much caffeine can disrupt our natural sleep cycles and prevent us from sleeping properly at night.


Another of the effects of caffeine, by blocking adenosine, is that it causes less blood to circulate in the blood vessels of the brain, which it can help relieve headaches, such as migraine headaches.

However, this effect may not be long-lasting, especially if we consume too much coffee: we become tolerant of caffeine and it no longer has the same effect stop headaches and may even appear to cause them.


Too much caffeine raises blood pressureThis may have to do with both the stimulating effect it has on the central nervous system and the fact that it causes vasoconstriction.

However, while the effects are remarkable, they are also known to be transient and generally have not been found to have a long-term effect on heart health.

Digestive problems

So coffee not only has effects on the brain, but on other organs and body systems.

There is evidence that coffee has a laxative effect, but in this case we cannot attribute all the responsibility to caffeine, because even consuming decaffeinated coffee we will have the same results.

It is thought that it could be because coffee helps to release the hormone gastrin, which stimulates digestion.

Raises cholesterol

In our body we have a certain amount of cholesterol circulating in the blood and we need it because it is one of the lipids that are used in the production of hormones, but a very large amount can cause plaque formation in the arteries, leading to serious conditions as the atherosclerosis.

Although it has been shown that coffee can have an effect on raising the level of cholesterol in the bloodThis not only has to do with the amount of coffee we consume, but also with the way we prepare it.

Unfiltered coffees, such as French press coffees, Turkish coffee or coffee that is only boiled live in water, are the ones that would cause this effect, possibly because in these cases there are compounds such as cafestol, which favor the increase of cholesterol in the blood.

So to continue enjoying coffee, but also in good health, you have to drink it in moderation and preferably filtered.
