Medication

Obesity is a serious disorder, which is an excessive amount of body fat. This disorder increases the chance to have other diseases, as heart problems, high blood pressure and diabetes. This is not just a cosmetic concern, according to some studies from the National Center for Health Statistics, in the United States, increased from obesity individuals from 19.4% in 1997 to 31.4% for the period January-September 2017 in people over the age of 20. Fortunately, this complex disorder has different kinds of treatment. Changing your lifestyle  can help you to lose weight and prevent or decrease the chance of having health problems associated with obesity. Dietary changes, physical exercises and other habits can help you to lose weight. You can also have other options as prescription medications and surgery. 

What are the signs and symptoms?

There are some classifications to define your degree of obesity. However, there are two  widely accepted. The first one is from the World Health Organization (WHO), which is based on body mass index (BMI). Your body mass is calculated by dividing your weight in kilograms by your height in meters squared. If your body mass index is 30 or higher you are considered obese.

Please find below the chart below, which shows the index and the weight status. 

BMI Weight Status
Below 18.5 Underweight
18.5-24.9 Normal
25.0-29.9 Overweight
30.0-34.9 Obese (Class I)
35.0-39.9 Obese (Class II)
40.0 or higher Extremely Obese (Class III)

For most people, the BMI can provide a reasonable estimate of body fat. However, for athletes and people who have more muscle, they can fall in the obese category even if they do not have excess of body fat.  Therefore, BMI should be evaluated differently in these type of people. The second classification widely accepted is the definition of obesity based on percentage of body fat, as follow:

Percentage of body fat Man: Higher than 25% and the limit from 21-25% Woman: Higher than 33% and the limit from 31-33%

Percentage of body fat
Man: Higher than 25% and the limit from 21-25%
Woman: Higher than 33% and the limit from 31-33%

When is it important to see a doctor?

If your BMI or your percentage of body fat is in the obese range, it is important to see a doctor. Your GP can help  you to understand the causes and the possible treatments to lose weight. To diagnose  obesity and possible treatments first, he will ask some exams and tests, as follow: 

  • The doctor will do general physical exams: measuring your height, checking your heart, lungs and abdomen, checking your vital signs, such as heart rate, temperature and blood pressure;
  • He will ask you about your health history: This is important to diagnosis the possible causes of your obesity. For example, your current diet, your stress levels, if you are taking other medications and any other issues about your health. He can also ask you about your family´s health history to analyze if you have the tendency to be obese.
  • He will calculate your BMI and will measure your waist circumferences: Both tests are important to determinate your overall health risks and it is good to do at least once a year. Fat stored in your waist can increase the chances to have some diseases, such as heart attack or diabetes.  For men, if you have a waist circumference greater than 102 centimeters, and for women, if you have more than 80 centimeters, the chances of having more health risks are higher than people with smaller waist circumferences.
  • Your GP can also ask for blood tests: According to the other tests and exams above, the doctor can ask for complement blood tests, for example, liver function tests, cholesterol test, thyroid test and others. 

After all these tests, the doctor can determine the cases of obesity and which treatment is adequate to your case.

What can cause Obesity? Which are the risk factors?

There are many risk factors and causes that may cause obesity. However, obesity happens when your body absorbs more calories than it is able to burn. The body stores these excess calories in fat form. There are some disorders that can cause obesity, for example, Cushing´s syndrome and Prader-Will syndrome, but usually they are rare. The most common causes are: inactivity, unhealthy diet and unhealthy eating habits.

It is always better to increase the level of daily exercises to avoid the weight gain;
  • Unhealthy diet and eating habits: The type of food and the quantity you eat, can interfere strongly in obesity. Nowadays, most of the people are consuming a diet full of fast food and are not eating healthy food such as vegetables and fruits, which increases the chance to have obesity.

  • Family habits: The way your family eats can impact in the way you eat. This can happen because  usually  family members share the same activities and eating habits;
  • Age: Despite the fact that obesity can occur at any age, but the tendency to gain weight will increase proportionally with age. This happens because during the years your metabolism is becoming slower and if you do not decrease the amount of food you eat, or increase the level of exercise, chances of suffering from obesity will rise.
  • Pregnancy: When you are pregnant, your body needs more calories to feed the fetus and you will gain weight. Unfortunately, some women after the baby is born, have difficulty losing weight which can lead to obesity;

There are others factors that can also influence the weight gain. But do not worry if you have one or more risk factors mentioned above. If you control your diet, change your habits and do more exercises, you probably will not become obese.
