What BMI makes you morbidly obese?
A BMI above 40 indicates that a person is morbidly obese and therefore a candidate for bariatric surgery. Bariatric surgery may also be an option for people with a BMI between 35 and 40 who suffer from life-threatening cardiopulmonary problems, diabetes, or other medical problems listed below.
The National Institutes of Health (NIH) define morbid obesity as: Being 100 pounds or more above your ideal body weight. Or, having a Body Mass Index (BMI) of 40 or greater. Or, having a BMI of 35 or greater and one or more co-morbid condition.
Class III obesity, formerly known as morbid obesity, is a complex chronic disease in which a person has a body mass index (BMI) of 40 or higher or a BMI of 35 or higher and is experiencing obesity-related health conditions.
- You are more than 100 lbs. ...
- You have a Body Mass Index (BMI) of over 40.
- You have a BMI of over 35 and are experiencing severe negative health effects, such as high blood pressure or diabetes related to obesity.
A BMI over 25 suggests you're overweight, while 30-39 indicates you're obese. A BMI of 40+ suggests morbid obesity.
Obesity is determined by your body mass index (BMI). This score is calculated by finding your height and weight on the BMI chart. Morbid obesity is defined by a BMI of 40 or greater.
This table shows us that a woman who is 5 ft. 4 in. tall is considered overweight (BMI is 25 to 29) if she weighs between about 145 and 169 pounds. She is considered obese (BMI is 30 or more) if she is closer to 174 pounds or more.
You are likely morbidly obese if you are: more than 100 lbs. over your ideal body weight, or. have a Body Mass Index (BMI) of over 40, or.
Four phenotypes of obesity have been described, based on body fat composition and distribution: (1) normal weight obese; (2) metabolically obese normal weight; (3) metabolically healthy obese; and (4) metabolically unhealthy obese. Sarcopenic obesity has been characterized, related to all the described phenotypes.
8 to 10 years lost, on average, is significant. However, experts are quick to note that many additional years are lost to obesity that simply does not result in death. A study published in the UK found that a total of 20 “healthy years” were lost to obesity.
What is the highest BMI ever recorded?
At the time of his death, he weighed 798 lb (362 kg; 57 st) with a Body Mass Index of 105.3.
Class 1: BMI of 30 to < 35. Class 2: BMI of 35 to < 40. Class 3: BMI of 40 or higher. Class 3 obesity is sometimes categorized as “severe” obesity.

So the answer to the question is essentially yes, people with obesity can still be healthy. However, what this study, and prior research, shows us is that obesity even on its own carries a certain cardiovascular risk even in metabolically healthy individuals.
Obesity is not a choice and making people feel ashamed results only in them feeling worse about themselves, a report by top psychologists says.
Your body will build up fat stores if you continue to eat more calories than your body can use during daily activities and exercise. Obesity and morbid obesity are the result of too much fat being stored in your body. Certain medications, such as antidepressants, can cause weight gain.

Having severe obesity can make it difficult to do everyday activities, such as walking, breathing, and sleeping. It can also increase the risk of cardiovascular disease, type 2 diabetes, and various other health conditions.
It is possible to be overfat without being overweight, meaning that you're storing fat within your body even though the scale says you're at a normal weight. And that distinction is key when it comes to heart health.
How many days can an obese person go without food?
In general, a person can survive up to 110 additional days for every 50 pounds of excess body fat depending on exertion levels, hydration, overall health, and other factors specific to that individual.
