Low-salt diet for cirrhosis: why it matters and how to follow it

TL;DR

• A low-salt (low-sodium) diet is a cornerstone of daily management for cirrhosis, especially with ascites or swelling.
• Most liver specialists recommend ≤2 grams of sodium per day (about 5 grams of salt).
• Reducing salt helps limit fluid retention, improve comfort, and support other therapies.
• Salt reduction is often more important than water restriction.
• Small, practical food swaps can make a big difference.

What is a low-salt diet for cirrhosis?

A low-salt diet for cirrhosis limits daily sodium intake to reduce fluid buildup in the body.

In cirrhosis, the liver’s reduced function leads to hormonal changes that cause the kidneys to retain sodium and water. Eating less salt helps counteract this process and reduces complications such as ascites (fluid in the abdomen) and leg swelling.

Why is salt restriction important in cirrhosis?

Salt restriction helps prevent fluid retention and makes symptoms easier to manage.

High sodium intake:

• Pulls water into the bloodstream and tissues
• Worsens ascites and edema
• Reduces the effectiveness of diuretics

Clinical guidelines consistently show that without salt restriction, other supportive measures are less effective.

How much salt is usually recommended?

Most guidelines recommend no more than 2 grams of sodium per day.

This equals:

• ≈5 grams of salt (sodium chloride)
• ≈1 teaspoon of salt total per day, including hidden salt in foods

This target is commonly used in patients with:

• Decompensated cirrhosis
• Ascites
• Fluid-related symptoms

Is sodium the same as salt?

No, but they are closely related.

• Salt = sodium + chloride
• Sodium is the part that affects fluid balance

Food labels list sodium, not salt.

As a rule of thumb:

• 1 g sodium ≈ 2.5 g salt

Understanding this helps when reading nutrition labels.

Which foods are high in salt and should be limited?

Processed and packaged foods are the main sources of excess sodium.

Common high-salt foods include:

• Ready meals and instant soups
• Processed meats (ham, bacon, sausages)
• Cheese (especially hard and processed cheeses)
• Bread and bakery products
• Sauces (soy sauce, ketchup, salad dressings)
• Snack foods (chips, crackers, salted nuts)

Even foods that do not taste salty can contain large amounts of sodium.

What foods are better choices on a low-salt diet?

Fresh, minimally processed foods are naturally low in sodium.

Better options include:

• Fresh vegetables and fruits
• Fresh meat, poultry, and fish (not cured or smoked)
• Eggs
• Unsalted rice, pasta, and potatoes
• Homemade meals using herbs, spices, lemon, or vinegar for flavor

Cooking at home gives you the most control over salt intake.

How can you reduce salt without losing flavor?

Flavor does not depend on salt alone.

Helpful strategies:

• Use herbs and spices (garlic, paprika, cumin, rosemary)
• Add acidity (lemon juice, vinegar)
• Toast spices to enhance aroma
• Use onion, ginger, and fresh herbs

Taste buds adapt over time, and many people find food more enjoyable after a few weeks.

How does a low-salt diet affect fluid intake?

Lower salt intake can reduce thirst and fluid retention.

For many people with cirrhosis:

• Reducing salt improves comfort
• Fluid restriction may become less strict or unnecessary (unless sodium levels are low)

This is why salt reduction is often emphasized before limiting water.

Is a low-salt diet safe for everyone with cirrhosis?

Most people with cirrhosis benefit from salt reduction, but needs can vary.

Extra guidance is important if you have:

• Poor appetite or unintentional weight loss
• Muscle wasting (sarcopenia)
• Kidney problems

In these cases, diet changes should balance sodium restriction with adequate calories and protein.

Practical tips for everyday life

Simple habits make a low-salt diet more sustainable:

• Read food labels and compare brands
• Aim for foods with <120 mg sodium per 100 g
• Avoid adding salt at the table
• Plan meals ahead to reduce reliance on convenience foods
• Keep low-salt snacks available

Keeping a food diary can help you reflect on patterns and prepare questions for your care team.
