Am I Obese?
Determining your weight status is a sobering task. But it's good place to start to determine your risk of dangerous health condition and to determine if you need to take action.
Your Body Mass Index (BMI) is one tool used to determine if you're of healthy weight, overweight, or obese. But a discussion with your doctor is also in order, even if you have a healthy weight, to identify any medical concerns. For example, not everyone who has high cholesterol is also overweight, although it can increase your risk; not everyone who gets cancer has a weight issue, although links between obesity and cancer have been seen.
To calculate your BMI:
(1) Multiply your weight in pounds by 703. (2) Divide that answer by your height in inches. (3) Divide that answer by your height in inches again. (4) Follow the chart below to see what category your BMI falls into.
BMI Category Chart
Below 18.5 -- Underweight
18.5 – 24.9 -- Healthy weight
25.0 – 29.9 -- Overweight
30.0 – 39.9 -- Obese
Over 40 -- Morbidly obese
Too Much Sugar in the Blood - Type 2 Diabetes
Type 2 diabetes reduces your body's ability to control blood sugar. It is a major cause of early death, heart disease, kidney disease, stroke and blindness. Risk factors for type 2 diabetes include:
- family history
- high cholesterol
- overweight and obesity.
However, the single best predictor of type 2 diabetes is being overweight or obese. In fact, almost 90% of people living with type 2 diabetes have a weight concern.
Diabetes cases among American adults have increased fourfold since the 1980's, and additional increases are expected, primarily due to the growing obesity epidemic.
Problems With the Ticker - Heart Disease and Stroke
Heart disease and stroke are the leading cause of death and disability for people in the U.S. Overweight people are twice as likely as normal weight people to have:
- high blood pressure
- abnormally high levels of blood fats, and LDL ("bad") cholesterol
-- all major risk factors for heart disease and stroke.
Being overweight also contributes to:
- angina (chest pain caused by decreased oxygen to the heart)
- sudden death from heart disease or stroke without any signs or symptoms.
If you are overweight or obese it’s likely you are physically inactive. Physically inactive people are twice as likely to develop coronary heart disease compared with regularly active people.
The Big C
Cancer is the second leading cause of death in the United States. It is responsible for about 22% of deaths.
Being overweight or obese raises your risk for:
About one third of cancer deaths are linked to excess body weight, poor nutrition and a lack of physical activity.
In a study published in 2018 in the CDC's Morbidity and Mortality Weekly Report obesity was found to be linked to 13 different kinds of cancers.
By 2030, nearly a half million Americans will be diagnosed with obesity-related cancers each year.
Obesity Contributes to Dementia and Mental Health Issues
Obese adults are more likely to suffer from depression, anxiety and other mental health conditions than normal weight adults. Obesity also increases the risk of experiencing a mood disorder.
New research suggests that obesity during midlife may increase the risk for later-life dementia.
Research published in the Alzheimer's & Dementia journal in 2017 suggests people who have a high body mass index (BMI) are more likely to develop dementia than those with a normal weight. However, as overt dementia develops in later years, body weight reduces, often below the body weight for those who remain healthy. Weight loss with dementia is caused by metabolic changes during the pre-dementia stage.
Maintaining a healthy weight might prevent, or delay, the onset of dementia.
Osteoarthritis is Linked With Obesity
Statistics show that obese adults are up to 4 times more likely to develop osteoarthritis of the knee than healthy-weight adults.
Osteoarthritis is a common joint problem -- often due to "wear-and-tear" of the knees, hips, and lower back.
The condition occurs if the tissue that protects the joints wears away. Extra weight can put more pressure and wear on joints, especially knees, causing pain.
This is further complicated by the fact that adults with osteoarthritis are significantly less likely to participate in physical activity compared to those without arthritis.
Sleep Apnea and Obesity
Those who are obese have greater risk suffer from sleep apnea, a serious condition.
Sleep apnea is a disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. It may be because obese patients have more fat stored around their neck making it harder to breathe. These breaks in breathing may last between 10 and 30 seconds, and in severe cases can happen hundreds of times per night. Sleep apnea can lead to serious, and often dangerous, daytime drowsiness. The risk for automobile accidents can skyrocket.
There are two types of sleep apnea:
Obstructive sleep apnea: when the nose or throat airways become blocked. partially or completely blocked. Excess tissue in the airway is more common in those who are overweight, and may lead to airway blockage during sleep when muscles relax.
Central sleep apnea occurs due to damage of the brain stem, possibly by infection or stroke. The brain stem helps to controls breathing.
If you think you suffer from sleep apnea, see your doctor. There are treatment options for this breathing disorder.
Kidney, Liver and Gallbladder Problems
Obese individuals are far more likely to develop kidney disease than normal-weight individuals. They are also at greater risk of nonalcoholic steatohepatitis (NASH), a liver disease which can lead to cirrhosis, in which the liver is permanently damaged and no longer able to work properly.
NASH is one of the major causes of cirrhosis in the U.S., only behind hepatitis C and alcoholic liver disease.
People who are overweight or obese are also at increased risk of having gallstones. Gallstones are hard pieces of stone-like material that form in the gallbladder. They're mostly made of cholesterol. Gallstones can cause stomach or back pain. Being overweight may result in an enlarged gallbladder that doesn't work well.
Obesity in U.S. Kids and Teens
According to the Robert Wood Johnson Foundation, data from October 2017 show that the U.S. childhood obesity rate (ages 2 to 19 years) stands at 18.5%. More than 200,000 youth under 20 years of age have type 2 diabetes, and the number at risk is even greater.
Obesity has an immediate and long-term effect on the health of children.
- Childhood obesity can be linked with increased risk of emotional problems and lower self-esteem.
- Depression, anxiety, and obsessive compulsive disorder can also set in.
- Bullying can be more common towards overweight children.
- A 2018 study shows that rates of cancer in young adults appear to be associated with obesity from childhood.
- Children who are obese have a greater chance of maintaining obesity in adulthood, and the associated health hazards that come along with obesity.
But the news is not all bad. Research shows that childhood obesity rates are starting to decline. Signs of progress are being seen where strategies have been put in place to make healthy eating choices available and boost physical activity. For example, in the federally-funded Women, Infants, and Children (WIC) nutrition program for low-income families in the U.S., the obesity rate among preschoolers dropped from about 16% percent to 14.5% and the rate of severe obesity dropped from roughly 2.1% to 2.0%. However, for these positive results to stay on track, these programs need to remain in-place and funded by the government.

Fight the Battle of the Bulge
Obesity is usually caused by taking in more calories than you burn because the body stores unused calories as fat.
Following a healthy lifestyle can help you prevent being overweight or obese. Get advice if you can. Meet with your doctor. Consult with a dietician. Follow a prescribed healthy eating plan and think about calories and portion size. Boost your exercise on a daily basis. Stay hydrated; water can help you feel more full and it's great for your health. Avoid sugar-ladened beverages like sodas and fruit juices.
Think about fresh vegetables, fruit, fiber, water and lean cuts of meat; keep the ice cream cone as a very occasional treat for healthy eating.

Top Tips For a Healthy Lifestyle
- Focus on portion size. Read this 2018 article to learn more about the "Nutrition Facts" labels, portion sizes and content of packaged foods. Watch the portion sizes in restaurants, too, and avoid all fast food. The portions served often are enough for two or three people. Children's portion sizes should be smaller than those for adults.
- Be active, stay active. Make personal and family time active. Find activities that everyone will enjoy. For example, go for a brisk walk, bike or rollerblade, or train together for a walk or run. Get at least 30 minutes of activity at least 6 days per week.
- Reduce screen time. Limit the use of TVs, computers, smart phones and tablets because they limit time for physical activity. Health experts recommend 2 hours or less a day of screen time that's not work or homework related. Kids may need even less.
- Keep track of your weight, body mass index, and waist circumference. Also, keep track of your children's growth and weight. Make your healthy routines become part of your every day routines.
- Check with your doctor before you begin any diet or exercise routine for advice and a stamp of approval.
