Hypotension has the potential to cause fainting. Hypotension includes acute hypotension and chronic hypotension, and acute hypotension often causes hypoperfusion of target organs. For cerebral underperfusion can occur stroke, and dizziness, headache and fainting can occur, so hypotension can potentially cause fainting. Hypotension is also often seen in physiological hypotension, such as in the thin elderly, women and children. Hypotension is often combined with conditions such as hypoglycemia, so sudden fainting can also occur. For people with normal blood pressure, when postural hypotension occurs due to a change in position, it often occurs leading to increased vagal excitability, which causes vasovagal syncope to occur, so for patients with hypotension it is recommended to clarify the presence or absence of disease and to treat the disease. If there is no related disease, appropriate adjustments can be made in the diet by eating more high-fat and high-salt foods to raise blood pressure.
