What Overweight Means
Overweight means having more body weight than is considered healthy for your height. This extra weight can come from fat, muscle, or fluid, but it is often related to having more body fat than is ideal. Doctors commonly use a measurement called body mass index (BMI) to estimate whether someone is overweight. BMI compares your weight to your height and gives a number that helps categorize weight status. A BMI between 25 and 29 is usually considered overweight. This is different from obesity, which is a higher level of excess body fat, usually with a BMI of 30 or more.
Why Overweight Matters in Health and Cancer
Being overweight can increase the risk of many health problems. These include diabetes, high blood pressure, heart disease, stroke, sleep apnea, arthritis, and certain types of cancer. Research shows that people who are overweight or obese have a higher chance of developing at least 13 different cancers, including breast (after menopause), ovarian, colorectal, pancreatic, and liver cancers. Carrying extra weight can also affect cancer treatment and recovery. Understanding your weight and working toward a healthy range can help lower these risks.
What You Might See or Hear About Overweight
You might hear the term overweight during doctor visits, in medical reports, or when discussing cancer risk factors. Your healthcare provider may talk about your BMI or waist size as ways to understand your body fat and health risks. They might also discuss lifestyle changes like diet and exercise to help manage weight. Sometimes, genetic factors or health conditions like metabolic syndrome or polycystic ovary syndrome (PCOS) can contribute to being overweight.
How Overweight Is Measured and Used by Doctors
Doctors use BMI as a simple tool to estimate body fat and categorize weight status. While BMI is helpful for populations, it doesn’t directly measure body fat and may not perfectly reflect health risks for every individual. For example, athletes with more muscle may have a higher BMI but not excess fat. Doctors may also measure waist circumference because fat around the belly (visceral fat) is linked to higher health risks. These measurements help guide discussions about health, cancer risk, and treatment planning.
Common Questions to Ask Your Care Team
If you hear you are overweight, you might ask your healthcare provider what that means for your health and cancer risk. You can ask how your BMI and waist size relate to your personal situation, what lifestyle changes might help, and whether you need support from a dietitian or other specialists. It’s also important to ask about safe ways to lose weight if needed and how weight might affect your cancer care or recovery.
Understanding Overweight in Context
Being overweight does not automatically mean you will develop cancer or other diseases, but it is a factor that can increase risk. It’s one part of your overall health picture, which includes genetics, lifestyle, and other medical conditions. Weight is not the only measure of health, and small changes can make a difference. Your healthcare team can help you understand what a healthy weight means for you and how to achieve it safely.
