[50F] Experiencing severe lightheadedness with associated symptoms

What might be happening

Based on the information you've provided, you may be experiencing:

• Orthostatic Hypotension: This is a form of low blood pressure that happens when you stand up from sitting or lying down. It can make you feel dizzy or lightheaded, and you might even faint.

  • Treatment typically involves lifestyle changes, such as drinking plenty of fluids and standing up slowly. In some cases, medications may be needed.

• Cardiovascular Conditions: Given your family history of cardiovascular disease and your symptoms of chest pain and changes in heartbeat, conditions such as arrhythmias or heart disease could be contributing to your symptoms.

  • Treatment would depend on the specific condition and could range from lifestyle changes to medications to procedures or surgery.

• Vestibular Disorders: These are conditions that affect the inner ear and balance, which can cause dizziness and lightheadedness.

  • Treatment typically involves physical therapy, medications, and in some cases, surgery.

What you can do

You should definitely seek medical attention given your symptoms. In the meantime:

1. Try to stand up slowly from a sitting or lying position.
2. Stay well-hydrated and avoid alcohol.
3. Try to avoid sudden changes in posture.
4. If you feel dizzy, sit or lie down immediately and lower your head.

What you should look out for

You should seek immediate medical attention if:

• Your dizziness is accompanied by a severe headache, chest pain, or trouble breathing.
• You have a rapid or irregular heartbeat.
• You faint or lose consciousness.
• Your symptoms are getting worse or not improving.
