What Is Protein?

Protein is an essential nutrient made up of smaller chemicals called amino acids. Your body relies on protein to:

• Provide Energy: Supplies fuel for daily bodily functions.

• Build and Repair: Helps make new cells, as well as maintain and rebuild muscle tissue.

• Transport and Signal: Carries other nutrients throughout the body and acts as chemical messengers.

• Protect: Supports your immune system to help fight off illness.

How Protein Affects Chronic Kidney Disease (CKD)

When your body processes protein, it breaks down and creates waste products. Healthy kidneys easily filter these wastes out of your blood, but damaged kidneys struggle to do so.

• Too Much Protein: Causes waste to build up in your blood, placing extra stress on your kidneys and making you very sick.

• Too Little Protein: Can leave you feeling weak and tired, while also increasing your risk of getting infections.

Finding the right balance protects your kidneys while keeping your body strong.

How to Get the Right Amount of Protein

Because every individual’s health situation is unique, managing your protein intake requires a personalized approach:

• Consult Professionals: Ask your doctor or a registered dietitian to determine your exact daily protein limit.

• Personalized Planning: Your specific diet depends on your level of kidney function and whether or not you are on dialysis.

• Monitor Changes: As kidney disease progresses, your nutritional needs will shift. Get regular blood tests and work with your care team to adjust your diet over time.

• Stay Committed: Adapting to dietary restrictions can be difficult, but sticking to your recommended guidelines is key to preserving your health.
