Obesity Risk Calculator

Obesity can put you at risk of many complications throughout your life. With this tool, you can calculate the risk of developing obesity-related complications for the next 10 years.


Enter your height, weight, and medical history to find out risk of various medical complications. It is possible to compare what is a risk level at the current weight and what it would be after 13% of weight loss. Use these results as a starting point to discuss with your doctor how to manage obesity and its complications.

Risk prediction is possible if the BMI is between 30 and 50, and the age between 19 and 70 years.

The risk reduction below is possible if 13% of total body weight loss is achieved.
Your weight after weight loss is 0 kg.

BMI is 0

Benefit can only be predicted if the BMI is between 30 and 50. *

Result:

  • Risk with current body weight
  • Risk after losing weight by 13%

HEART AND VASCULAR DISEASES/ RISKS

Hypertension
Dyslipidemia

Atrial fibrillation
Unstable angina/ myocardial infarction

DIABETES

Type 2 diabetes

OSTEOARTHRITIS

Hip/ knee osteoarthritis.

BREATHING

KIDNEY DISEASE

Chronic kidney disease

Risk predictions are based on the study that has used the UK primary care database with records of 570,000 adult patients. *

Based on whether patients maintained or lost their weight during the initial four-year period of the research, they were divided into two groups. Follow-up was conducted over a period of 15 years to determine differences between the two groups of patients regarding the development of ten obesity-related comorbidities.

Based on the information you provided, the data show an average risk in both study groups – the one, where the patients have maintained a stable body weight and the another, where the patients have lost an average of 13% of their initial body weight.

Dieting, prescription weight loss medications, and referrals to a nutritionist or bariatric surgery were also noted in the study group that lost body weight.Dieting, prescription weight loss medications, and referrals to a nutritionist or bariatric surgery were also noted in the study group that lost body weight.
