How can doctors tell if I have liver failure?
Doctors look at:
Blood tests to check how well your liver functions and find out what's causing your liver failure
Urine tests, blood tests, and chest x-rays to see if your liver failure is affecting other parts of your body
How do doctors treat liver failure?
There are no treatments that actually make your liver get better. However, doctors will have you do things to put less stress on your liver:
Not drink alcohol or take medicines that can hurt your liver
Eat less red meat, fish, cheese, and eggs
Eat more vegetable protein (such as soy)
Eat less salt (by avoiding salty foods and by not adding salt to your food)
If your liver gets worse quickly, doctors will treat you in the hospital. Treatment may include:
Fluids through a vein to keep your blood pressure up
Laxatives (medicine to help you pass stool) or enemas (fluid pushed into your anus and into your intestines to help you pass stool)—helps get rid of poisonous substances (toxins) from your body
Glucose (a sugar) given by vein (IV), if you have low blood sugar
Blood transfusions or medicine to help your blood clot if you're bleeding
Breathing tube and breathing machine (mechanical ventilator) if you have serious trouble breathing
A liver transplant (surgery to remove a failing liver and replace it with a healthy one from a donor) can fix liver function. However, a liver transplant isn’t right for all people with liver failure.
