Orthostatic Hypotension
Orthostatic hypotension is a sudden fall in blood pressure that occurs within a few minutes of standing up. The brain briefly receives less blood, causing lightheadedness, blurred vision, or fainting. It is more common in older adults and people with conditions such as diabetes, Parkinson’s disease, or autonomic nerve disorders, and can also be a side effect of certain blood-pressure or diuretic medicines.
Medicine used to treat Orthostatic Hypotension
Why it happens and how it is managed
The most common triggers are dehydration, prolonged bed rest, excessive heat, and standing up too quickly. In hot, humid climates common across Southeast Asia, fluid loss through sweating can make symptoms noticeably worse.
Simple steps help most people: rising slowly, drinking enough water, adding a little extra salt to the diet (where the heart allows), and wearing compression stockings. When lifestyle changes are not enough, midodrine is the primary medicine used to raise blood pressure in the standing position. It works by tightening blood vessels and belongs to the broader group of heart and blood pressure treatments.
If you experience fainting, chest pain, or repeated falls, see a doctor promptly to identify any underlying cause.
