Diagnosis
Before your procedure, a doctor or nurse will ask about your health, medicines, and any dizziness you have had. They may check your blood pressure and heart rate while you sit, stand, or lie down.
Tests that may be done
- Blood pressure and pulse checks
- Questions about your dizziness and symptoms
- A simple test of balance or walking
- An electrocardiogram (ECG) to check your heart rhythm, if needed
What to expect at your appointment
You may have your vital signs checked on the day of the procedure. If you feel dizzy, tell someone right away. They can help you sit or lie down and make sure you are safe.
Treatment
Treatment for dizziness on the day of a procedure focuses on keeping you safe and comfortable. Your care team can adjust how you sit, move, and when you get up. If dizziness is caused by anxiety or fasting, it often settles with simple measures.
Self-care at home
- Sit down or lie down if you feel dizzy.
- Take slow, deep breaths and try to stay calm.
- Do not stand up suddenly; get up slowly.
- Ask your care team if you are allowed to drink clear fluids or have a small snack.
- Wear comfortable shoes and ask for help when walking.
Medical treatments
Your care team may give you fluids through a vein (intravenous fluids) if you are dehydrated. They may also prescribe medicines to reduce nausea or vertigo, but you should never take any medication for dizziness without asking your doctor. You will not be given anything unless it is safe for you before your procedure.
When is surgery considered?
If the dizziness could interfere with your surgery, your team might delay or adjust the plan. This is rare, but safety comes first.
Living with this condition
After your procedure, dizziness may continue for a little while. Always get up slowly and hold onto a stable surface. Ask for help if you feel unsteady. Most people feel back to normal within a few hours or a day.
Lifestyle tips
- Take your time when changing positions.
- Stay well-hydrated if your doctor allows.
- Avoid screens and bright lights if they make you feel worse.
- Plan to have someone with you for the first 24 hours after a procedure, especially if you are still dizzy.
Diet and exercise
Follow the exact instructions about eating and drinking before and after your procedure. Afterward, start with small sips of water and light foods, like crackers or toast, if your doctor says it is okay. Avoid heavy exercise until you feel steady.
Mental health and emotional wellbeing
Feeling dizzy can be scary and increase anxiety. Remember that it is very common and your care team has seen it many times. It may help to tell a nurse about your worries so they can support you.
Prevention
You cannot always prevent dizziness, but you can lower your chances by following pre-procedure instructions, staying relaxed, and telling your care team about your history of dizziness. If you take medicines for high blood pressure, ask your doctor whether to take them on the day of the procedure.
Complications
If left untreated
- If you ignore severe dizziness, you could fall and injure yourself.
- Fainting may cause a head injury.
- Severe dizziness may delay your procedure, though this is uncommon.
Long-term outlook
The outlook is very good. Most dizziness before a procedure goes away quickly and does not cause any lasting problems. Your care team will monitor you and keep you safe.
