Obesity is a medical condition in which excess fat of the body accumulated in the parts of the body especially in the belly which causes negative effects on health. A person who is obese or not obese is determined on the basis of his/her body mass index (BMI). Adults with more than 30 BMI is considered as overweight as per the centre for disease control (CDC).
Obesity is correlated with various diseases like heart disease, high blood pressure and type-2 disease, cancer and sleep apnea. High BMI may cause certain other diseases, which creates many problems and may lead to sudden death.
Obesity may vary to race, ethnicity and region as Americans are more prone to get obesity while Africans are not. But in general, obesity is more common in developed countries. Due to obesity, more than 4 million people die annually in the world.
Causes of Obesity
Eating more calories than requires by the body causes accumulation of fat that resulted in obesity. If a person is not utilizing the calories he takes, not exercising as regularly then he will get obesity. But there is a catch, always eating more than requires calorie does not result in obesity but due to some other reasons obesity occurs like:
Getting older- As we ages, our metabolic rate slow down and muscle mass is also very low which helps to gain weight.
Genetics- If your parents are obese then there is obesity in your genes which may cause obesity in your body.
Low Sleeping- If you don’t take enough sleep, you will be probably at risk of having obesity because certain hormones secreted in your body may cause hunger and resulted in high-calorie consumption and storage.
Hyperthyroidism- When the thyroid levels increase in our body due to problems in the thyroid gland it resulted in obesity.
Excessive Eating- If someone eats too much oily and fried food and does not work up daily, he may be prone to get obesity.
Diagnosis of Obesity
There are different ways to diagnose obesity. One simple way to diagnose obesity is by calculating your BMI. If your BMI is more than 30 you are obese. The second one is the skinfold thickness test and waist to hip comparison test. Obesity can also be measured with the help of certain blood tests like lipid profile tests and thyroid tests. Your doctor may ask you to perform ECG and Eco test to measure your heart condition if obesity is diagnosed.
Complications due to Obesity
It is said that obesity is the gateway to diseases. If you are obese, your body will gradually develop a lot of diseases like heart disease, type-2 sugar, pain in joints, Stroke, fatty liver, stone in the gallbladder, inability to walk for long-distance and cancer. It also causes inflammation in the body which gradually develops cancer.
Treatment of Obesity
The treatment of obesity is depended upon the extent of fat present in the body. The simple and tested method of losing weight is to follow a strict diet plan and exercise or physical activities.
