Here are some ways to take care of your liver: 

• Eat a healthy diet: Eat a balanced diet with fruits, vegetables, whole grains, and fiber. Limit saturated fat, refined carbohydrates, and sugar. Avoid raw or undercooked shellfish. 

• Drink water: Staying hydrated helps your liver function. 

• Exercise: Aim for at least 150 minutes of exercise per week. 

• Manage your weight: If you're overweight, try to lose weight slowly. 

• Be careful with alcohol: If you're diagnosed with liver disease, your doctor may recommend limiting or avoiding alcohol. 

• Be careful with medications: Follow the instructions on all medicines and nonprescription drugs. Don't take more than the recommended dose of acetaminophen, which is found in many cold and flu drugs. 

• Be careful with herbs and supplements: Check with your doctor before using any herbal supplements, as some can harm the liver. 

• Prevent hepatitis: Prevent hepatitis A, B, and C. 

A doctor can assess your symptoms and determine the best tests to determine how well your liver is functioning. These tests may include a liver function test, liver scan, liver biopsy, CT scan, ultrasound, or MRI scan. 

What are the signs of a healthy liver? Signs include stable weight, clear skin, good digestion, regular bowel movements, healthy cholesterol and blood sugar levels, and sustained energy.
