  1. 1. Obesity Done by : Mohammed A Qazzaz
  2. 2. Obesity All of us love to have a well-built bodies, or at least not to be obese, and we have the right to think like that, because obesity is not just a cosmetic concern, it's also a risk for some health problems, such as heart disease, diabetes and the high blood pressure and others.
  3. 3. I am sorry it looks dangerous but don’t panic, you can prevent your health problems easily, and you can lose weight through change the life and dietary style, increase physical activity and others.
  4. 4. What is Obesity? Obesity is that, you have a high amount of fat in your body, and from that definition you can notice that, obesity is not about more weight, it's about more fat . To understand this you may weight more because you are tall. And this is normal.
  5. 5. Now you want to know if you are obese or not, and this is easy, all you want is to measure your weight in Kilograms (kg) and your height in meters (m), and then use this formula Or you can use this one too
  6. 6. This formula will give you your body mass index (BMI). the obesity is diagnosed when the (BMI) is 30 or more. now look to this table below to know more about the (BMI). BMI Result Less than 18.5 Underweight 18.8-24.9 25-29.9 30-40 More than 40 Normal Overweight Obese very obese
  7. 7. Now with the (BMI) you can diagnose yourself as an obese or not, but still one problem. Some people like the muscular athletes find their (BMI) higher than normal, when they most likely have a normal amounts of fat in their bodies, and the answer is that, they weight more not because of fat, but because of muscles.
  8. 8. What are the causes of obesity ? Our daily bodies activities need energy come from food we eat, and more exercise and activities burn more calories that we get from food. And not just the activities need to burn calories, also many metabolic reactions in the body need the energy from food, such as to warm up in cold weather and to sweat in the hot days. But when our food calories amounts exceed the body need, they will be stored in the body as fat.
  9. 9. So the causes of obesity is a combination of states and risk factors that work together to store more fat in our bodies, and these factors include: •Inactivity: without activity you don’t burn as much calories. and you need to have more exercise to burn the excessive calories.
  10. 10. •Diets: some bad eating habits like high calories diets epically in the night, or skipping a healthy breakfast, and replace it by junk fast food, all of that increase the body fat . •Pregnancy: some women after the baby is born have an increasing in their weight, and if they don’t lose that weight, with many pregnancies after that, they may become obese.
  11. 11. •Lack of sleep: this cause disturbances in the body hormones, and increase the appetite. you also may crave to height calories food. •Drugs: some medications lead the body to gain more weight, these drugs include, diabetes medications, steroids and beta blockers, anti-seizure medications, antipsychotic medications and antidepressants drugs.
  12. 12. •Medical conditions: some diseases and syndromes lead the body to store more fat and gain weight like Cushing syndrome. some disease low the metabolic rate in the body and low the amount of burned calories every day such as the hypothyroidism. And some diseases lead the patient to low his activity, such as the arthritis or maybe the patients with paraplegia •Genetics: genes affect the amount of body fat we store and where to store, •Family lifestyle: not because of the genes we find the obesity runs in the families, it also because of their life style and the food they eat. We can notice that some countries such as USA, have more obese people than others countries like Japan and this is because the culture and the life style.
  13. 13. •Age: obesity could occur at any age, but when we get age we lose more amount of muscles built. more amount of muscles give higher rate of metabolism and calories burning. When we lose them we reduce the calories burning and tend to fill the body with fat.
  14. 14. What are the complications of obesity?
