Your Kidneys Are Carrying More Than You Think

Why does excess weight affect the kidneys?

When people gain weight, they often worry about their appearance.

But your kidneys worry about something else.

Every extra kilogram makes them work harder.

Your kidneys are two small organs, each about the size of your fist. Yet every day they filter nearly 180 litres of blood, removing waste and keeping your body in balance.

When you’re overweight, your body needs more blood, more oxygen, and more filtration. To keep up with the demand, your kidneys are forced to work overtime.

The benefits of losing weight

At first, they cope.

• But over the years, this extra workload begins to damage the tiny filters inside the kidneys. Protein starts leaking into the urine—often the first warning sign that the kidneys are under stress.
• Being overweight doesn’t just affect the kidneys directly.
• It also increases the risk of:
• Diabetes
• High blood pressure
• High cholesterol

Start with small, sustainable changes

Fatty liver

• Heart disease
• Sleep apnea
• Together, these conditions can make kidney disease progress much faster.
• Can losing weight really help?
• Absolutely.
• Even losing 5–10% of your body weight can:
• Reduce pressure on the kidneys
• Decrease protein leakage in the urine

Improve blood pressure

Improve blood sugar control

Reduce the risk of heart disease

Slow the progression of kidney disease

You don’t need a crash diet.

Start with small, sustainable changes:

Eat smaller portions.

Fill half your plate with vegetables.

Reduce sugary drinks, sweets, fried foods, and packaged snacks.

Walk for 30 minutes most days.

Sleep well and stay active.

Small changes, repeated every day, produce big results over time.

Remember…

Your kidneys cannot ask for a lighter workload.

But you can give them one.

The key message

Every kilogram you lose is a gift to your kidneys.

Don’t lose weight to fit into smaller clothes.

Lose weight so your kidneys can keep working for many more years
