Weight Loss Blood Tests Manchester

Identify the medical barriers to weight loss — before you give up

If you are eating well and exercising regularly but still struggling to lose weight, the problem may be medical, not motivational. Thyroid dysfunction, insulin resistance, hormonal imbalances, and other conditions can make weight loss extremely difficult without the right treatment. Our Weight Loss Blood Test in Manchester helps identify these hidden barriers quickly.

Frequently Asked Questions

What is insulin resistance?

Insulin resistance is when your cells don't respond properly to insulin, leading to higher blood sugar and increased fat storage — particularly around the abdomen. It is a precursor to type 2 diabetes and is very common.

Can a thyroid problem cause weight gain?

Yes. Hypothyroidism (underactive thyroid) significantly slows metabolism, making weight gain easy and weight loss very difficult. A thyroid test can identify this.

Do I need to fast for this test?

Yes. Fasting for 10–12 hours is important for accurate fasting insulin, glucose, and HbA1c results.

Can Myway Clinic prescribe weight loss medication based on my results?

Yes. Our Independent Prescribers can discuss Mounjaro (tirzepatide) or Wegovy (semaglutide) eligibility based on your results, BMI, and medical history.
