Considered the "epidemic of the 21st century". It is defined as the increase in total body fat that results from an exaggerated intake of calories that exceeds the total amount of energy used.
According to the World Health Organization (WHO), in 2017, more than 2.3 billion adults were overweight and more than 700 million were overweight. Every year at least 2.8 million people die from obesity or overweight worldwide. In 2020 it is estimated that we will reach the figure of 2.4 billion adults who are overweight.

It is estimated that more than 400,000 people die prematurely each year in the United States due to diseases related to obesity. In regards to our country, 7 out of every 10 Mexicans suffer from overweight. On the other hand, around 30% of Mexicans suffer from obesity, which gives us the unprofitable first place in the world in this field.

In Mexico, the direct complications of obesity such as cardiovascular diseases (heart infarction) and type 2 diabetes mellitus represent the first and third causes of death in the adult population.


In order to classify a person as obese and classify it among its different grades, it is important to know the body mass index (BMI), a quotient that results from dividing the weight in Kg between the height in meters squared.


< 18.5 LOW
18.5 - 24.9 NORMAL
25.0 - 29.9 OVERWEIGHT
30.0 - 34.9 SLIGHTLY OBESE
40.0 - 49.9 MORBID OBESITY
50.0 - 59.9 SUPER OBESITY

RISK OF OBESITY. - With a BMI greater than 30 the risk of the following conditions is increased: 55% in mortality, 70% in coronary artery disease (eg angina pectoris), 75% in acute myocardial infarction and 400% in type 2 diabetes mellitus.

DISEASES RELATED TO OBESITY. - Type 2 diabetes mellitus, hypertension, osteoarthropathies (joint damage), hyperlipidemias (high cholesterol and triglycerides), heart disease, gallstones (gallstones), gastroesophageal reflux, sleep apnea, asthma, infertility, urinary incontinence, some types of cancer (breast, uterus, colon).

PSYCHOLOGICAL PROBLEMS RELATED TO OBESITY. - Depression, low self-esteem, social isolation, discomfort in public, decreased sexual appetite.

BENEFITS OF OBESITY SURGERY. - Improve the general health of the patient, improve the quality of life, increase life expectancy, prevent and correct diseases, achieve greater self-esteem, provide a sense of well-being.

CANDIDATES FOR OBESITY SURGERY. - All patients with a BMI ≥ 40. Those patients with a BMI ≥ 35 + coexisting diseases (diabetes mellitus, hypertension, sleep apnea, joint damage, etc.)

What is digestive endoscopy and what is it done for? - Gastrointestinal endoscopy or gastroscopy is a medical test designed to detect problems in the upper digestive system, mainly the stomach, esophagus and duodenum (detect diseases such as helicobacter, gastric problems, etc ...). It is a fairly common test that helps diagnose and even treat digestive problems at the same time.

How is a digestive endoscopy done? - Digestive endoscopy is a test similar to colonoscopy, except that, in this case, the tube is inserted through the mouth and not through the anal canal.

Indeed, to perform gastroscopy the doctor introduces a flexible tube through the mouth, with the aim that the tube reaches the upper digestive system. This tube has a thickness of about one centimeter and a length of about one meter. In addition, it incorporates a micro-camera at the end that is inserted, with the aim of allowing the doctor to explore the interior of the patient. Also, this device called endoscope can also be coupled with other small work tools with which the doctor can perform another series of operations, such as the removal of polyps. It is a test usually done by the main doctor with the help of an assistant. First, they will open a way in the arm to administer to the patient some medication that makes them relaxed and drowsy during the test. It is likely that in many cases the patient does not remember anything.

The doctor will place a device in the mouth to prevent the patient from closing it during the process. An anesthetic spray will also be administered in the area of the mouth and throat, to minimize discomfort at the time of introducing the endoscope. The doctor will advance the endoscope little by little to the duodenum, asking the patient little by little to swallow, to facilitate the passage of the tube. It is advisable not to swallow unless the doctor asks for it. On the other hand, endoscopy is usually done lying on the left side of the body, but during the process it is likely that the doctor makes us change position but better explore some area.

Throughout the process, the doctor can see on a screen attached everything that is registering the endoscope. Also, you can also add other tools to the device, to perform biopsies or other tests or operations at the same time.

It is a test that lasts about 15-20 minutes, although it can be extended in case the doctor finds something suspicious or needs to perform some additional task.

It is also important to note that before performing a high digestive endoscopy it is necessary to be without eating the previous 6-8 hours so that there are no remains and the exploration is easier. If an emergency endoscopy is performed, it is likely that the doctor has to introduce a nasogastric tube before cleaning the stomach. Unlike colonoscopy, it is not necessary to perform a complete preparation and evacuation of the digestive system.

In addition, it should be noted that to carry out the test it is not necessary to take any medication.

What risks does a gastroscopy involve? - Many people are scared at the prospect of performing a high digestive endoscopy. However, there is nothing to worry about since it is a very usual and very safe test.

It is true that it is a medical test that can be somewhat uncomfortable and that we notice some discomfort or strange sensations. for example, swelling and tingling in the throat from the anesthetic spray. It can also happen that the person feels a sensation of suffocation when introducing the endoscope, but it is not common and is usually more caused by the nerves than by the test itself. During the examination, the patient may feel gas, abdominal pain or desire to vomit. Be careful with vomiting, as it could enter the respiratory tract and reach the lungs, causing pneumonia. Finally, endoscopy could also produce cardiac arrhythmias, but this is already a very remote possibility.
