Manage your weight

Get the support you need to manage your weight with a home blood test, free insights, and GP support.

What can a blood test tell you about weight management?

If you’re finding it hard to lose weight or putting on weight for no particular reason, a home blood test might help you understand why. If you're carrying some excess weight, it’s also worth checking your liver function and diabetes risk.

Combined with GP-reviewed results and evidence-based ways to improve your weight, take your health into your own hands.

Blood tests related to weight management


HbA1c (diabetes)

If you carry any excess weight, it can increase your risk of type 2 diabetes. A HbA1c test measures your average blood glucose levels over the last few months. This helps indicate your risk of pre-diabetes and diabetes.



Testosterone is a hormone that's essential for both men and women's health. Low testosterone levels might affect your sleep quality and sleep duration.


Liver function

Your weight and liver health are tightly linked. If you carry excess weight, it can damage your liver function.


Thyroid function

Your thyroid gland produces hormones that control your body's metabolism. If it's over or underactive, it can affect your weight.



Testosterone plays a role in red blood cell production, which is important for energy. It also helps maintain your mood, muscle and bone strength, sex drive, and fertility.


Omega-3 fats

Omega-3 fatty acids are types of fat that you can only get from your diet. A diet high in omega-3 fats is linked to an increased metabolism and can help aid weight loss.



If you carry excess weight, it’s linked to increased inflammation in your body — a risk factor for heart disease. A high-sensitivity C-reactive protein (hs-CRP) test can measure this inflammation.
