Feeling Tired, Forgetful, or Bloated? You’re Not Alone

Are you struggling with low energy, brain fog, mild digestive issues, or unexplained aches? Many of us put these down to stress or getting older, but sometimes they’re your body’s way of signalling underlying health issues—like subtle changes in liver function.

What Does the Liver Actually Do?

Your liver is one of your most hardworking organs. It helps to process nutrients from food, filters toxins from your blood, and even regulates cholesterol vital for heart and cardiovascular health. When your liver isn’t working at its best, all sorts of subtle symptoms can arise—even before tests at your GP pick up obvious problems.

Common early symptoms of poor liver health include:

Why Do These Symptoms Happen?

Liver problems can cause waste products to build up in your blood. This impacts your mind, digestion, and cardiovascular system. Early testing can help you catch changes before they become more serious.
