Obesity is a term that means you weigh at least 20% more than what is considered a normal weight for your height. It makes you more likely to have conditions including:
Heart disease and stroke
High blood pressure
Gallbladder disease and gallstones
Breathing problems, such as sleep apnea (when a person stops breathing for short episodes during sleep) and asthma
Not everyone who is obese has all of those problems. The risk rises if you have a family history of one of those conditions.
Also, where your weight is may matter. If it’s mostly around your stomach (the “apple” shape), that may be riskier than if you have a “pear” shape, meaning that your extra weight is mostly around your hips and buttocks.
