WHAT ARE THE HEALTH RISKS OBESITY?
Being overweight or obese isn’t a cosmetic problem. It greatly raises the risk in adults for many diseases and conditions.
OVERWEIGHT AND OBESITY-RELATED HEALTH PROBLEMS IN ADULTS
Coronary Heart Disease
Coronary heart disease (CHD) is a condition in which a substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
Plaque can narrow or block the coronary arteries and reduce blood flow to the heart muscle. This can cause angina (an-JI-nuh or AN-juh-nuh) or a heart attack. (Angina is chest pain or discomfort.)
As your body mass index (BMI) increases, so does your risk of having CHD and a heart attack. Obesity also can lead to heart failure. This is a serious condition in which your heart can’t pump enough blood to meet your body’s needs.
High Blood Pressure
Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. If this pressure rises and stays high over time, it can damage the body in many ways. Your chances of having high blood pressure are greater if you’re overweight or obese.
Stroke
Being overweight or obese can lead to a buildup of plaque in your arteries. Eventually, an area of plaque can rupture, causing a blood clot to form at the site. If the clot is close to your brain, it can block the flow of blood and oxygen to your brain and cause a stroke. The risk of having a stroke rises as BMI increases.
Type 2 Diabetes
Diabetes is a disease in which the body’s blood glucose, or blood sugar, level is too high. Normally, the body breaks down food into glucose and then carries it to cells throughout the body. The cells use a hormone called insulin to turn the glucose into energy.
In type 2 diabetes, the body’s cells don’t use insulin properly. At first, the body reacts by making more insulin. Over time, however, the body can’t make enough insulin to control its blood sugar level.
Diabetes is a leading cause of early death, CHD, stroke, kidney disease, and blindness. Most people who have type 2 diabetes are overweight.
