Q. When I was exercising, I felt dizzy and suddenly the sky was dizzy with dizziness. Why?


A. vagus vascular neurogenic syncope ( vasovagal syncope ) is first suspected. Vascular vagus nerve palsy has no abnormality in the heart itself, but some external factors temporarily cause an imbalance in the autonomic nervous system, which slows the heart rate and lowers the blood pressure, leading to loss of consciousness and collapse.
It occurs mainly in the younger layer, and is caused by a variety of external stimuli such as closed air with cloudy air, frequent sitting or standing in a hot place for a long time, disgusting smell, horrible sight, severe pain, defecation, urination, Vagus nervous system is activated, and syncope occurs.
Confirmation is a test of incontinence called slope table test. Of course, the possibility of arrhythmia is not completely excluded.

Uric acid is the final product of degradation caused by metabolism of a substance called purine, a component of nucleic acid, in the liver after the cell has reached its end of life and the nucleic acid has been liberated. Purine, a precursor to uric acid, is ingested through food. When purines are metabolized in the liver and become uric acid, uric acid is excreted in the urine via the kidneys. If you have gout, you should know and eat foods that have high purine content (liver, kidney beans, herring, mackerel, anchovy, etc.).

Alcohol reduces the excretion of uric acid in the body, and drink with alcohol is said to increase the amount of uric acid in the blood because of the high purine content. Among beer, beer is known to cause gout attacks most commonly because of the presence of purine in beer. Regardless of the type and amount of alc...

This is because leukocytes in the body are severely inflamed during the process of eliminating the uric acid crystals formed in the joints or around the joints. At this time, anti-inflammatory treatment should be started with ice fomentation. The most commonly used is oral anti-inflammatory (anti-inflammatory) agent. If these anti-inflammatory treatments are done early, most focal gout attacks are effectively treated. Gout attacks usually do not require anti-inflammatory treatment, but the inflammation gradually improves over time. However, without proper antiinflammatory treatment, arthralgia can last for weeks, so it is advisable to start anti-inflammatory treatment as soon as you have gout attacks. If the joint is still uncomfortable even though you think it has passed, you may still have symptoms because the severe inflammation has not co...
