Obesity blood test

Professionally updated: January 27, 2026

If you have tried numerous diets and programs without losing weight, it is essential to recognize that being overweight is not only related to calorie intake. There are other factors that may be involved. For example, if there is inflammation present in the body, it can lead to increased levels of cortisol, which can cause weight gain. Irregularities in blood sugar, high liver values, metabolic problems and hormonal imbalances can also be a cause of being overweight. With that in mind, we offer a specialized blood test package for obesity, which aims to identify any underlying causes of being overweight. These tests can be a step towards starting appropriate treatment or counseling.
