I fainted 2 times in a row in the toilet of the Internet caf

The primary cause of your dizziness is that when you sit and stand up for a long time, blood flows to the lower limbs immediately, while the heart does not increase blood supply so quickly, resulting in head ischemia. The secondary reason is that vomiting causes the organs and muscles around the stomach and intestines to move violently, which aggravates the demand for blood, so the head is more ischemia.

In addition, stomach pain and vomiting may be an attack of acute gastroenteritis, and the body will also consume energy to resist. I wonder if you have eaten to replenish your energy in 10 hours? Don't think that sitting and playing on the computer doesn't consume physical strength, what's so strange about being weak?

It's not to scare you, sitting for a long time will easily form blood clots, which will cause edema of the lower limbs, secondary varicose veins, dermatitis, pigmentation, stagnation ulcers, and severe (when the blood clot breaks off and swims to other parts) will cause severe ischemia or interruption of blood flow in organs and tissues, such as insufficient blood supply to the brain, unstable angina, and even necrosis, such as acute myocardial infarction, stroke, etc.

Causes include malnutrition, hypoglycemia, and lack of sleep to dizziness and nausea. Then there is the computer-assisted ejection for a long time, which will make you dizzy, nauseous, and weak. After paying attention to these, you will not get dizzy.

Even if it's made of iron, you can't carry it.
