Obesity is a medical condition characterized by being fat or overweight. It is defined by genetic and environmental factors that are hard to control when having food restrictions. Obesity is categorised as having a BMI of 30 and above. This disease can increase the risk of developing conditions such as diabetes, hypertension, and sleep apnea.
Every disease has its signs and symptoms. Many people can tell when they have gained weight based on the signs and symptoms they are presenting. Some of them include the following
- Clothes feeling tight
- An indication of the scale that you have added weight
- Possessing extra fat around your waist
- Having a higher Body mass index and waist circumference
The balance between intake of calorie and energy expenditure ascertains the weight of a person. If the person takes in more calories than he or she metabolises, the individual gains weight. Consequently, the typical causes of obesity are overeating and physical inactivity. The following are some of the common causes of this condition.
- A high carbohydrate diet
- eating frequency
- Slow metabolism
- Physical inactivity
- Physiological factors
In genetic factor, someone is more likely to develop obesity if his or her parents are obese. Overeating results in weight gain particularly if the diet contains a lot of fats.
Obesity can be diagnosed in various ways. Nevertheless, one of the common methods of finding out whether you are obese or overweight is through body mass index. This method estimates your body fat and determines whether you are at a risk of getting diseases that are associated with excess fat. It works by assessing your weight in relation to your height. Other ways include weight to height tables and body fat percentage.
Weight to height tables
- The tables show the general ranks of the average weight and overweight for the height of adults
Body fat percentage
- Medical professionals say that the percentage of body weight is a good indication of obesity. Men with above 25% of fat and women with more than 32% are regarded as being obese.
There are various treatment methods of obesity. Some of them include dietary modification, behaviour modification, exercise, medications and surgery.
- The calorie restrictive diets are classified into low calorie diets and very low calorie diets. In low calorie diets, the individuals should take 500 to 1000 calories a day less than they burn. In very low calorie diets, the intake is limited to only 400 to 800 calories a day.
- Patients using the drug therapy lose up to 10% of their excess weight. Some of the medications work by interfering with the body’s ability to absorb particular nutrients in food.
- Bariatric surgery works by sealing off the stomach to reduce the amount of food consumed.
