These 9 Signs of Alcohol Intolerance You Might Be Unaware Of

Posted on

After a couple of drinks, some people start feeling symptoms similar to an attack of vegetovascular dystonia, an allergic reaction, or other ailments. They often don’t even realize that these unpleasant side effects are caused by alcohol.

We collected a list of signs of ethanol intolerance, which can easily be confused with the symptoms of other diseases.

There are 2 types of alcohol intolerance:

  • Congenital is a genetically determined feature in which the body is unable to process ethanol and its metabolites.
  • Acquired alcohol intolerance arises from the use of medications, illnesses, or injuries.

How do alcohol-intolerant people differ from others?

Normally, after alcohol gets into the blood, ethanol is slowly broken down into acetaldehyde, which is later processed by enzymes for quite a long time. People with alcohol intolerance have a distortion of enzymatic activity in their body. Which means that alcohol dissolves too quickly and acetaldehyde concentrates in the blood and provokes the emergence of numerous unpleasant symptoms.

People with high arterial pressure often suffer from throbbing pain in the temples, tinnitus, and dizziness. If the pressure, on the contrary, decreases, then the symptoms can be a loss of vision, lethargy, and dizziness.

2. Runny nose

We’re used to accepting symptoms such as sneezing, a blocked nose, and being short of breath as those of a common cold. However, the source of the symptoms may actually come from alcohol intolerance. There is a huge number of capillaries in the nasal mucosa. When exposed to ethanol, edema develops on them, making it difficult to breathe and causing a sense of nasal congestion.
