Class III obesity, formerly known as morbid obesity, is a complex chronic condition that can lead to several serious health issues. There are many treatment options for class III obesity, including healthy lifestyle changes, behavioral and psychological therapy, medication and weight loss procedures.
Overview
What is morbid obesity (now known as class III obesity)?
Class III obesity, formerly known as morbid obesity, is a complex chronic disease in which you have a body mass index (BMI) of 40 or higher. The BMI scale isn’t always accurate. So, healthcare providers may use other tests and tools to assess obesity.
Class III obesity can lead to several serious health conditions, like Type 2 diabetes and heart disease. The good news is that it’s treatable. There’s no quick fix. But together, you and your healthcare team can create a tailored plan to reach a weight that’s healthy for you.
Symptoms and Causes
What are the symptoms of class III obesity?
There are no specific symptoms of class III obesity. The main feature of class III obesity is having a body mass index (BMI) of 40 or higher.
Class III obesity can cause side effects and complications in many parts of your body.
What are the complications of class III obesity?
Class III obesity can contribute to the development of several health conditions, including:
Atherosclerosis (plaque buildup inside your arteries)
Breathing issues, like obesity hypoventilation syndrome (OHS)
Certain cancers, like pancreatic, colorectal, breast and liver cancers
Depression or other mental health conditions
Heart disease
High blood pressure (hypertension)
Kidney disease
Liver disease
Osteoarthritis
Metabolic syndrome
Sleep disorders, like obstructive sleep apnea
Type 2 diabetes
Class III obesity can also cause fertility issues.
What causes class III obesity?
Class III obesity is a complex disease that has several contributing factors. The main reason your body stores adipose tissue (body fat) is an imbalance between the number of calories you consume and the amount your body uses. A lack of physical activity can play into this, as well.
But several other factors contribute to how much food you eat, the type of food you eat and how your body uses that energy. Every person’s body is unique and metabolizes energy differently. Some people are at a greater risk of weight gain than others.
Class III obesity rarely results from a lack of willpower to lose weight or a lack of “control” over the amount of food you eat.
Contributing factors to obesity include:
Genetics. There are at least 15 obesity-related genes. Certain genetic syndromes can cause obesity, as well, like Cohen syndrome, Down syndrome and Prader-Willi syndrome.
Hormonal imbalances. Hormone-related conditions that can lead to weight gain include Cushing syndrome, hypothyroidism and polycystic ovary syndrome (PCOS).
Certain medications. Antidepressants, antipsychotic medications, antiseizure medications, corticosteroids and other medications can lead to weight gain.
Cultural factors. Prevalent advertising for calorie-dense foods and increased portion sizes can contribute to developing obesity.
Environmental factors. Exposure to chemicals known as obesogens can change your hormones and increase adipose tissue in your body.
Financial factors. Easier financial and/or geographical access to fast foods compared to more nutritious, whole foods can lead to weight gain.
Geographical factors. Having limited access to parks or other places to exercise can lead to obesity. Having few safe or easy ways to walk in your neighborhood can, as well.
What are the risk factors for class III obesity?
Risk factors for developing class III obesity include:
Lack of sleep. Many studies show a link between high BMI and people who don’t get enough sleep (typically less than seven hours a night).
Chronic stress. Long-term stress triggers the production of hormones (like cortisol) that control your energy balances and hunger cues.
Your age. The risk of weight gain increases as you age.
Your sex. Females have more adipose tissue than males from puberty onward. Pregnancy and menopause can also contribute to excess adipose tissue.
Your race. In the United States, rates of obesity are highest in non-Hispanic Black people, followed by Hispanic people, then white people.
You can’t change some of these risk factors. But healthy lifestyle changes may decrease your risk of developing obesity.his issue:
So, it may well be that self discipline alone can solve the subject issue for those interviewed, who, one hopes, will seek the help the Cleveland Center or other medical outfit offers.
