Alcoholic beverages have inevitably become a part of the many social events we share in. There are plenty of warnings about the negative health effects of alcohol. However, many people still drink too much or too often.

Some people may have the ability to control their urge to drink. However, others end up becoming addicted and start to depend on the effects it gives them. The most worrisome thing is that there are strong economic and social interests that prevent alcohol from being appropriately regulated.

Because of this, everyone should be more aware of the consequences and effects of alcohol consumption, and choose the amount that is most suitable for their health. Often, we don’t think about the immediate effects of alcohol, and that’s why today we’re going to describe them for you in detail.

1. The effects of alcohol: uncontrolled blood sugar spikes

Right after you consume an alcoholic beverage, your blood sugar levels either drop or rise considerably. This reaction can lead to us feeling weak, or even dizzy or disorientated.

2. Irregularities in your heart rhythm

Excessive consumption of alcohol can speed up your pulse and cardiac activity. The toxins in alcohol don’t take long to travel through your bloodstream, and so they quickly affect the different systems of your body and heart.

3. Redness of the skin

Another of the effects of alcohol on your circulatory system is an increase in vasodilation and visible redness of the skin. In fact, some people have very obvious changes in their body temperature or begin to sweat.

4. Blurred vision

Problems with clear vision are among the most common effects experienced by those who don’t moderate their consumption of alcohol. Toxins that travel through the blood reduce your vision and cause it to become blurry.
This reaction is very dangerous, not just because it can negatively impact your vision in the long term, but because it causes an increase in the number of accidents.

5. Lack of coordination

A person who drinks too much alcohol finds it hard to keep their coordination under control. Their body is not only weak; they lose their balance and their reflexes too.

Because of this, a drunk person risks falling or getting into a serious accidentIt should also be noted that alcohol also affects inhibitions, and the capacity for self-control.

6. Digestive problems

Alcohol alters the natural pH of the stomach and, as a result, this can lead to irritation and inflammation of the lining that protects it from acidic gastric juices. This can cause the development of problems like gastritis and acid reflux.

In the long term, it can also lead to more serious complications, such as duodenal ulcers, stomach cancer, or cancer of the esophagus.

7. Dehydration

Your kidneys are the organ that suffer the most from excessive intake of alcoholic beverages. Because they become overworked trying to eliminate all those toxins through your urine, you also lose liquids and mineral salts that are essential for hydration.

8. Headaches

High levels of toxins and the difficulty your metabolism has at working fast enough to process the alcohol are the two reasons you have headaches after a night of drinking. That’s why it’s common for you to experience an increase in muscular tension and strong pains, like a migraine, hours after ingesting alcohol.

9. Vomiting

Nausea and vomiting are common after having too many drinks or when a certain drink is too strong. This reaction is accompanied by severe digestive discomfort, as well as dizziness and difficulty maintaining balance.

Some people aren’t even able to tolerate moderate amounts of alcohol, and, as a result, they experience this symptom immediately.

10. Liver problems

Your liver is the main organ responsible for metabolizing the substances in alcohol. Because of this, excessive consumption affects it directly and can cause serious problems with its function.

If your level of intoxication is regular and uncontrolled, the liver becomes more fibrous and you develop what is known as cirrhosis of the liver.

As you’ve seen, under no circumstances should you drink too much alcohol. While it can be consumed occasionally, it’s best to learn to control how much you drink.
