What’s The Cause of Low Blood Pressure after Surgery?

There was an incident in Australia where the doctor had difficulty knowing the cause. That patient had tummy surgery in Melbourne years ago and all of a sudden after the procedure, he experienced low blood pressure after surgery. But truthfully, there are many causes as to why this incident happens.

Anesthesia

Anesthetic agents can affect your blood pressure. It can happen while anesthesia is still in effect. In some people, anesthesia causes a significant drop in blood pressure. If this is the case, doctors will monitor you carefully and give you medications through an IV to help bring your blood pressure back to normal.

Hypovolemic shock

This is when your body goes into shock due to severe blood or fluid loss. A loss of a large amount of blood, which can happen during surgery, causes a drop in blood pressure. Less blood means the body can’t move it as easily to the organs it needs to reach.

Since shock is an emergency, you need to be treated in the hospital. The treatment goal is to try and restore the blood and fluids in your body before the damage affects your vital organs.

Septic shock

Sepsis is a life-threatening complication of acquiring bacterial, fungal, or viral infection. It causes the walls of small blood vessels to leak fluids into other tissues. If this condition becomes severe, it leads to septic shock and significantly drops the blood pressure.

You’re vulnerable to these infections if you’re in the hospital recovering from surgery. It is treated with antibiotics and extra fluids.

Home Remedies

If you still have low blood pressure as you get home, here are some home remedies

  • Stand up slowly: Take time to move around and stretch prior to standing. This will help get blood flowing in your body.
  • Minimize intake of caffeine and alcohol: These two drinks can cause dehydration.
  • Eat small, frequent meals: Some people experience low blood pressure after eating, and smaller meals help reduce your risk.
  • Increase oral fluid intake: Staying hydrated helps prevent low blood pressure.
  • Eat more salt: With the permission of your doctor, you can increase your salt intake by adding more to foods or taking salt tablets if your levels are off the chart. Don’t start adding salt without asking your doctor first.

 

Is there a need to worry?

Really low blood pressure numbers put you at risk of damage to vital organs, like your heart and brain, due to lack of oxygen.

Low numbers at this level are more likely to happen while you’re being treated in the hospital for emergencies like blood loss or a heart attack.

But in most cases, low blood pressure doesn’t really require treatment.

If you’re concerned about the continuous low blood pressure, it’s best to see your doctor, especially if you’re experiencing symptoms, like:

  • dizziness
  • lightheadedness
  • blurry vision
  • nausea
  • dehydration
  • cold clammy skin
  • fainting

Your doctor will be able to tell if there’s another health issue going on or if you need to add or change medications.
