overview
Orthostatic hypotension – also called orthostatic hypotension – is a type of low blood pressure that occurs when you stand up from a sitting or lying position. Postural hypotension can make you feel dizzy, dizzy, and possibly even pass out.
The orthostatic hypotension can be mild and the episodes can last less than a few minutes. However, prolonged orthostatic hypotension can indicate more serious problems. It is therefore important to see a doctor if you frequently feel dizzy when you stand up.
Occasional (acute) orthostatic hypotension is usually caused by something obvious, such as dehydration or prolonged bed rest, and is easy to treat. Chronic orthostatic hypotension is usually a sign of another health problem, so treatment will vary. Orthostatic hypotension (postural hypotension) Treatment in Hyderabad
symptoms
The most common symptom is lightheadedness or dizziness when you stand up after sitting or lying down. Symptoms usually last less than a few minutes.
Signs and symptoms of orthostatic hypotension include:
- Dizziness or lightheadedness when standing
- Blurred vision
- Weakness
- Fainting (syncope)
- confusion
- nausea
The reasons
When you stand up, gravity causes blood to collect in your legs and stomach. This lowers blood pressure as less blood returns to your heart.
Special cells (baroreceptors) near your heart and neck arteries usually recognize this drop in blood pressure. Baroreceptors send signals to centers in your brain that tell your heart to beat faster and pump more blood, thereby stabilizing blood pressure. These cells also narrow blood vessels and raise blood pressure. Orthostatic hypotension (postural hypotension) Treatment in Hyderabad
Orthostatic hypotension occurs when something disrupts the body’s natural process of fighting low blood pressure. Many conditions can cause orthostatic hypotension, including:
Dehydration. Fever, vomiting, insufficient fluids, severe diarrhea, and vigorous exercise that involve excessive sweating can lead to dehydration, which reduces blood volume. Mild dehydration can cause symptoms of postural hypotension such as weakness, dizziness, and fatigue.
Heart problems. Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack, and heart failure. These conditions prevent your body from responding quickly enough to pump more blood while standing.
Endocrine problems. Thyroid disease, adrenal insufficiency (Addison’s disease), and hypoglycemia can lead to orthostatic hypotension. Same goes for diabetes – which can damage the nerves that help send signals that regulate blood pressure.
Risk factors
Risk factors for orthostatic hypotension include:
- Age. Orthostatic hypotension is common in people aged 65 and over. Special cells (baroreceptors) near your heart and the arteries in the neck that regulate blood pressure may slow down as you get older. It can also be more difficult for an aging heart to accelerate and compensate for drops in blood pressure.
- Medication. These include medicines used to treat high blood pressure or heart disease such as diuretics, alpha blockers, beta blockers, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, and nitrates.
Other drugs that can increase your risk of postural hypotension include drugs to treat Parkinson’s disease, certain antidepressants, certain antipsychotics, muscle relaxants, drugs to treat erectile dysfunction, and narcotics.
Using drugs that treat high blood pressure with other prescription and over-the-counter drugs can lead to low blood pressure.
Some diseases. Certain heart conditions such as heart valve problems, heart attacks, and heart failure; certain nervous system disorders such as Parkinson’s disease; and diseases that cause nerve damage (neuropathy), such as diabetes, increase the risk of low blood pressure.

Exposure to heat. Being in a hot environment can lead to profuse sweating and possibly dehydration, which can affect your health.
