Understanding Obesity: Diagnosis, Health Risks, and Related Conditions

Obesity is more than a number on the scale. It is a chronic health condition that can affect many parts of the body and increase the risk of developing other health problems. Understanding obesity and its possible complications can help you take an active role in protecting your health.

What is obesity?

Obesity occurs when there is an excessive amount of body fat that may negatively affect health. One of the most common tools used by healthcare professionals to screen for obesity is body mass index (BMI), which is calculated using your weight and height.

Although BMI can be useful, it does not tell the whole story. Your healthcare provider may also consider your waist measurement, medical history, blood pressure, blood tests, lifestyle, and other factors when evaluating your health.

Most importantly, obesity should not be viewed as a personal failure. Many factors can contribute to obesity, including genetics, metabolism, sleep, medications, environment, stress, eating patterns, physical activity, and other health conditions.

Why does obesity matter?

Living with obesity can increase the likelihood of developing several other health conditions, sometimes referred to as comorbidities.

These conditions can affect your heart, blood sugar, liver, sleep, joints, mental health, and overall quality of life. The risk can vary from person to person, which is why a healthcare professional may recommend a comprehensive health assessment.

Obesity and type 2 diabetes

Obesity can increase the risk of developing type 2 diabetes. Excess body fat can make it harder for your body to use insulin effectively, which can cause blood sugar levels to rise.

Your healthcare provider may recommend blood tests to check your blood sugar and determine whether you have diabetes or are at increased risk of developing it.

The good news is that improving metabolic health can have important benefits. Depending on your individual situation, changes in nutrition, physical activity, weight, medications, and other treatments may help improve blood sugar control.

Heart disease and high blood pressure

Obesity is also associated with high blood pressure, abnormal cholesterol levels, heart disease, and stroke.

You may not notice symptoms from high blood pressure or high cholesterol, which is why regular checkups are important. Your healthcare provider can assess your cardiovascular risk and recommend appropriate screening and treatment.

Taking care of your blood pressure, cholesterol, blood sugar, and weight can be an important part of protecting your heart.

Fatty liver disease

Obesity can increase the risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD), sometimes referred to as fatty liver disease.

This condition occurs when excess fat builds up in the liver. Many people have no symptoms, so it may be discovered during routine blood tests or imaging studies.

In some people, MASLD can progress to liver inflammation and scarring. If you have obesity, diabetes, or other metabolic risk factors, your healthcare provider may evaluate your liver health.

Sleep apnea and poor sleep

Obesity can increase the risk of obstructive sleep apnea, a condition in which breathing repeatedly stops or becomes blocked during sleep.

If you experience these symptoms, talk with your healthcare provider. Sleep apnea can be treated, and improving sleep can make an important difference in your overall health and quality of life.

Joint pain and mobility problems

Carrying excess weight can place additional stress on your knees, hips, back, and other joints. Over time, this may contribute to joint pain and osteoarthritis.

Pain can also make it more difficult to exercise or remain physically active, creating a cycle in which reduced activity and weight gain can reinforce one another.

Your healthcare team can help you find safe and realistic ways to improve mobility and physical activity according to your individual needs.

Emotional health matters too

Obesity can affect emotional well-being as well as physical health. Some people living with obesity experience depression, anxiety, low self-esteem, or social isolation.

It is also important to recognize that weight stigma and discrimination are not healthcare solutions. Feeling judged can make people less likely to seek medical care or talk openly about their health.

If your weight is affecting your emotional well-being, talk with your healthcare provider. Mental health is an important part of overall health and deserves the same attention as physical health.

What should you discuss with your healthcare provider?

If you are living with obesity or are concerned about your weight, consider asking your healthcare provider about your individual health risks. Depending on your situation, your healthcare professional may evaluate:

• Blood pressure
• Blood sugar and diabetes risk
• Cholesterol
• Liver health
• Sleep apnea
• Joint and mobility problems
• Mental and emotional well-being
• Medications that may affect weight
• Other medical conditions and risk factors

This evaluation can help identify problems that may not cause noticeable symptoms yet.

Treatment is about more than losing weight

There is no single approach to treating obesity that works for everyone.

Depending on your health, goals, and medical history, treatment may include changes in eating habits, physical activity, behavioral support, prescription medications, or metabolic and bariatric procedures.

The goal is not simply to reach a particular number on the scale. Treatment can also focus on improving blood pressure, blood sugar, cholesterol, sleep, mobility, energy, and overall quality of life.

If you have tried to lose weight before and regained it, you are not alone. Obesity is a chronic condition, and managing it may require ongoing support and adjustments over time.

Taking the next step

If you are concerned about obesity or any of the conditions associated with it, you do not have to manage it alone.

Start by having an honest conversation with your healthcare provider. Ask what your current health risks are, whether you should be screened for obesity-related conditions, and which treatment options may be appropriate for you.

Your health is about much more than your weight. Understanding your individual risks and getting the right support can be an important first step toward better health and a better quality of life.
