No one warned me about the consequences of having gastric sleeve surgery.

Four and a half years ago I had Gastric Sleeve surgery

In my particular case, it was not that I was significantly obese, but rather a genetic predisposition to fat and a love of sports that I could not fully satisfy at my weight.

However, there are many things that I have learned the hard way after the surgical procedure, that no doctor tells you and only friends and family who have had it done can tell you. Here I want to give you some things that you should take into account if you plan to do it or if you have just done it and are in the process.

Hypertension, sleep apnea, diabetes mellitus; Severe obesity causes health problems and risk of complications from regular disease conditions are many of the reasons why a person decides to have a sleeve gastrectomy.

And the reasons for having this surgery are very personal, they can vary from simply health reasons to psychological reasons such as wanting to improve self-esteem, and why not? social acceptance.

There are people whose condition of being overweight, with a high BMI body mass index; And even with extreme obesity, they suffer from anxiety of being accepted thanks to the beauty paradigms that the media and advertising establish as acceptable today. Others are at a point in their lives where their quality of life is impaired by excess weight that limits their physical activities.

I experienced the change that this surgery represents on two levels personally:

Feeding Habits.

My fat brain within weeks of having the surgery urged me to fill my plate with food with lots of food, with the same foods that I used to enjoy before. ! Oh surprise ! Foods fried in oil, not only caused me gas and heartburn when trying to digest them; they repulsed me. My body asked me at least once a week for a good piece of meat, just juicy. I couldn't see the plate full of food, because I had a couple of hard times overeating and having to throw up again. By eating less, my body cried out desperately for more food between meals, and I started eating the recommended 5 times, not because the doctor told me to, but because I necessarily needed it and the energy drops were the first warning sign that he had to rush something to his stomach.

Personally, I recommend that those between meals be as nutritious as possible, zero snacks or soft drinks, but fruit and nuts that fill you up and feed you. Then your meals at regular times, preferably well balanced nutritionally because your body now has another rhythm and needs.


The first effect after several weeks of having to start re-evaluating what was in the closet and practically having to buy everything again, is very positive. Me Self esteem went through the roof, I started to notice that the girls were looking at me more (seriously!), people were throwing compliments at you and cheering you on. Socially, and it hurts to say, they treat you differently. There is a new balance, as you lose more weight, you feel more energetic, and more active you are in all aspects of your life: at work, sports, with your children when going out to the park, I cannot stop describing.

Your character changes, let no one tell me otherwise, you are more affable and social, and any trace of depression that the fat caused you socially disappears.

However, and I can affirm it with great certainty, although not for myself; in married couples this effect is a challenge to marital stability. There are those who are suddenly in a situation of believing themselves so attractive after seeing compliments rain down from everywhere, that suddenly, if the foundations are not well established, marriages are destroyed. The ego grows to such an extent that it is believed to be and to be above the partner, and the parameters are lost. I have already seen several close-up cases in which the other person enters a kind of emotional crisis of wanting to be liked more, and believing that they are entitled to something better without weighing the consequences. Infidelity rates increase. This is an open secret in bariatric surgeons' offices, which is not discussed; but it happens.

That extra quota of energy that is felt, it is important to channel it into positive activities such as sports and work, not only because of the need to focus it positively, but for another more concrete one. Your skin, if you were very obese, is stretched, and when you lose weight so quickly it will tend to stretch irregularly if you do not have a good skin tone. In other words, the skin can wrinkle, and only with good nutrition and exercise you will be able to avoid having a tummy tuck for a couple of years, or being left with your arms and jowls hanging down, with a prune appearance.

In my case it was the best decision of my life, because I knew how to focus well, and be sufficiently applied with my diet. I urge you not only to go to a surgeon before surgery, but to a psychologist and review your situation in detail. Your life is going to change, and you must prepare for it.

Remember, this is my personal experience. Whether you are overweight to suffer from obesity  morbid, if you are thinking of having bariatric surgery; Also consult with your doctor about other types of surgery such as adjustable gastric band, gastric bypass, etc. depending on your body mass index, your nutrition, lifestyle and even your psychological state.

Any medical procedure, especially the gastric sleeve intervention, has consequences by reducing the length of the small intestine, or when the size of the stomach is reduced; although the results in the medium term will be formidable.

The truth is that if you have done it, your life now has to be in balance, and the natural has to be your lifestyle!

The main difference between gastric sleeve and gastric bypass lies in the surgical technique and the impact on digestion:

  1. Gastric sleeve: Focuses on reducing the size of the stomach. There is no alteration in the intestine, and nutrient absorption remains relatively normal.
  2. Gastric bypass: It involves both the reduction in the size of the stomach and the alteration of the intestine. This results in significantly reduced absorption of calories and nutrients.

Gastric sleeve, technically known as sleeve gastrectomy, is a surgical procedure for weight loss. In this procedure, a significant portion of the stomach is removed, leaving a tube-shaped or “sleeve” portion. This reduces the size of the stomach, limiting the amount of food that can be consumed and thus promoting weight loss.
