Severe obesity and vitamin D deficiency treatment options before bariatric surgery: a randomized clinical trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Obesity, which has various complications and co-morbidities, is an epidemic issue worldwide.

Vitamin D deficiency (VDD) is a well-known metabolic disorder among patients with severe obesity.

Who Took Part

The study group was 100 patients.

The age groups tagged for this paper are adults, both men and women.

This was a single-blinded, randomized clinical trial on 100 patients who were referred for bariatric surgery from 2016 to 2018.

Vitamin D (VitD) level was checked before surgery for the patients included in the study, if their VitD level was <30 ng/mL.

How the Study Was Run

In design terms this was a randomized and single-blind study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Only one side, usually the patients, was kept unaware of whether Vitamin D, K2, Magnesium and Zinc was given.

What Was Measured

While they are good candidates for bariatric surgery, this deficiency can affect the outcome of surgery negatively.
