If you've been noticing the numbers on the scale creeping up without a clear reason, you should be looking beyond the surface. Our blood tests for weight gain can give you valuable insights into your overall health and can help uncover the factors influencing your weight.

Hormone imbalances and other underlying health issues can directly impact your metabolism and weight. By understanding the underlying causes of your weight gain, you can take steps to manage it better. Our tests are tailored to check your thyroid, blood sugar, cholesterol levels, hormone balance, liver health, vitamin D levels, and more.

  1. Why do I need this test?

    If you're experiencing unexplained weight gain, these tests can help shed light on the potential root causes. Hormone testing for weight gain is a key step to finding answers because, as you may know, they are in charge of controlling most of what goes on in your body. Knowing more about your blood sugar levels can tell you if you have diabetes or insulin resistance, another common cause of weight fluctuations. Other biomarkers can shine a light on potential kidney and liver problems that can affect the pounds you carry on your body.

  2. What are blood tests for weight gain?

    Weight gain blood tests are a series of biomarkers that analyze your blood to identify the effectiveness of your metabolic functions or, in other words, how your body’s using and storing energy. They can help determine if certain medical conditions or imbalances influence your weight. These tests have been designed to help humans experiencing unexplained weight gain understand the root cause of this issue.

  3. Which blood tests are recommended for unexplained weight gain?

    If your scale is going up without you wanting it to, some recommended blood tests typically include:

    • Thyroid profile (measures your thyroid function)
    • Hemoglobin HbA1c (measures your blood sugar level over the past few months) and insulin levels (measures your body’s response to sugar)
    • Cortisol (measure stress levels in the body)
    • Lipid profile (can tell you how your heart and arteries are doing)
    • Hormone tests (like testosterone and estradiol, can help you identify hormone imbalances)

    Some of our blood tests for unexplained weight gain may also include liver and kidney function markers and inflammation markers to leave no stone unturned.

  4. How often should I have blood tests if I'm experiencing unexplained weight gain?

    In most cases, it is recommended that you get tested at least 2 to 3 times per year if you’re experiencing any weight fluctuations that cannot be explained. The exact frequency at which you should be getting a blood test for weight gain depends on the underlying conditions you may have or the specific treatments you’re undergoing. It may also depend on your specific goals, so discussing the right frequency with your trusted health professional is best.

  5. Can a blood test reveal why I'm gaining weight despite eating well and exercising?

    Blood tests can help unveil medical conditions that, despite your efforts, can affect your weight, such as hormonal imbalances & insulin resistance. However, it's important to note that there can be many factors behind weight gain, which might have to be addressed in different ways. To fully understand your weight gain, you must aim to get a broad and comprehensive evaluation of your health that includes blood tests, lifestyle evaluation, examination of your medical history, and a complete physical exam.

  6. Do I need to visit a doctor?

    Nope. You don't need a doctor's visit to get a test with us.

  7. How do I get my results?
