When the temperature is low before heating, the blood vessels are constricted, the blood pressure is increased, and the blocked parts of the blood vessels are more likely to bleed. However, compared to the familiar stroke, there are some extracerebral strokes that are not as well known, but have an aggressive onset, so you need to take extra precautions. Eye Stroke Your eyes are fine, but you wake up and find that you can’t see. This means that you may have suffered an “eye stroke”. The most important symptom is a painless but rapid loss of vision, says Prof. Zhang Ming, who says “eye strokes” are most common in the elderly. Arteriosclerosis, hypertension, and hyperlipidemia can all cause strokes. The early morning hours are the most common time for strokes in the eyes. If you wake up in the morning and notice a sudden loss of vision, seek prompt medical attention. Leg Stroke When blood flow in the arteries of both lower extremities is blocked, the muscles and nerve tissues within their supply area are damaged, and the dreaded leg stroke occurs. Blood clots attached to the heart are the main culprit in leg strokes. Abdominal strokes are relatively rare. The onset of the disease is characterized by severe abdominal pain and rapid onset of shock. The cause is not fully understood and may be related to hypertension, atherosclerosis, etc. When patients with these diseases have severe pain in the abdomen, they should go to the hospital promptly.
