What is BMI?
The Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person.
The BMI is defined as the body mass divided by the square of the body height and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in meters.
How to calculate your BMI?
Here’s the formula:
BMI = weight / height²
A graph of body mass index as a function of body mass and body height. The dashed lines represent subdivisions within a major class.
BMI is a common tool for deciding whether a person has an appropriate body weight. According to the National Institutes of Health (NIH):
A BMI of less than 18.5 means that a person is underweight.
A BMI of between 18.5 and 24.9 is ideal.
A BMI of between 25 and 29.9 is overweight.
A BMI over 30 indicates obesity.
However, BMI should not be the only measure method for an individual to assess whether his weight is ideal or not. Because there’re many other factors that have an impact on your health.
Waist-hip ratio (WHR), waist-to-height ratio (WtHR), and body-fat percentage are also effective ways to measure your healthy weight.
Obesity, even though it’s a completely treatable disease, has become a global health concern. It’s defined by having an excessive amount of body fat and measured by a body mass index (BMI) of greater than or equal to 30. This epidemic is caused by many factors, and it’s important to remember it’s no one’s fault. Over-consumption of food isn’t the only factor leading to obesity. Genetic and environmental components contribute as well.
When a person is obese, their weight is considered higher than the recommended range for a healthy individual. BMI is a simple off the cuff formula to categorize a person’s weight. It identifies the level of risk a person potentially faces if their weight isn’t managed. The higher the weight, the greater the risks on their health. This chart describes the different classifications of obesity.
Class 1: BMI of 30 to < 35
Class 2: BMI of 35 to < 40
Class 3: BMI of 40 or higher can be termed “severe” or “extreme” obesity.
Measuring body fat accurately often requires the skill of a health professional. BMI serves as a valuable and non-specific tool used to discuss weight ranges by measuring a person’s weight relative to their height. However, it doesn’t take into account a person’s specific body fat percentage. BMI can only provide a partial diagnosis of obesity. It’s recommended you speak to your healthcare provider to determine a more accurate diagnosis.
What are obesity symptoms?
The treatment of obesity seems simple. Eat less and exercise more. However, obesity can become a life long struggle due to the underlying reasons. These variables show up in a variety of symptoms.
Across social media, there is a dominant portrayal that slim equates to the beauty that causes emotional distress in obesity. Depression becomes one of the most common symptoms. People feel unattractive in their physical appearance and can be the subject of ridicule and discrimination. Those feelings bring on shame and isolation. Eating more may even be a coping mechanism to deal with that rejection. Take the chicken or the egg phenomenon. Which came first? As depression ensues, people may deal with it by eating more, causing obesity. As a person gains weight, their depression may worsen causing them to eat more, like a vicious cycle.
Other day-to-day health problems that result from obesity include breathlessness, increased sweating, snoring, inability to cope with sudden physical activity, back and joint pain, consistent fatigue, low confidence, and self-esteem.
Almost half of all cases of Diabetes Mellitus are linked to obesity. Commonly known as Diabetes, this metabolic disorder is a result of high blood sugar levels over an extended period. Diabetes symptoms show up as increased hunger, frequent urination, and increased thirst. The long-term complications if left untreated include cardiovascular disease, foot ulcers, damage to the eyes, stroke, and chronic kidney disease.
