Gastric Sleeve

Gastric Sleeve (Gastrectomy)

How Is Sleeve Gastrectomy Performed in Tijuana surgery center in Mexico?

We perform the sleeve gastrectomy as a laparoscopic procedure. This involves making five or six small incisions in the abdomen and performing the procedure using a video camera (laparoscope) and long instruments that are placed through these small incisions.

During the laparoscopic sleeve gastrectomy (LSG), about 75% of the stomach is removed leaving a narrow gastric “tube” or “sleeve”. No intestines are removed or bypassed during the sleeve gastrectomy. The LSG takes one to two hours to complete.

How Does Sleeve Gastrectomy Cause Weight Loss?

Sleeve gastrectomy is a restrictive procedure. It greatly reduces the size of your stomach and limits the amount of food that can be eaten at one time. It does not cause decreased absorption of nutrients or bypass your intestines. After eating a small amount of food, you will feel full very quickly and continue to feel full for several hours.

Sleeve gastrectomy may also cause a decrease in appetite. In addition to reducing the size of the stomach, sleeve gastrectomy may reduce the amount of “hunger hormone” produced by the stomach which may contribute to weight loss after this procedure.

Who Do We Offer Laparoscopic Sleeve Gastrectomy in Tijuana surgery center in Mexico?

This procedure is primarily used as part of a staged approach to surgical weight loss. Patients who have a very high body mass index (BMI) or who are at risk for undergoing anesthesia or a longer procedure due to heart or lung problems may benefit from this staged approach. Sometimes the decision to proceed with a two-stage approach is made before surgery due to these known risk factors. In other patients, the decision to perform sleeve gastrectomy (instead of gastric bypass) is made during the operation. Reasons for making this decision intraoperatively include an excessively large liver or extensive scar tissue that would make the gastric bypass procedure too long or unsafe.

In patients who undergo LSG as a first stage procedure, the second stage (gastric bypass) is performed 12 to 18 months later after significant weight loss has occurred and the risk of anesthesia is much lower (and the liver has decreased in size). Though this approach involves two procedures, we believe it is safe and effective for selected patients.

Are You a Candidate Who Can Benefit from the Gastric Sleeve Procedure?

  • Persons with a BMI 30-35 or greater
  • Persons that need to lose 50 lbs. or more
  • Some patients deemed high risk in other bariatric surgeries
  • Those who have experienced past failures with traditional weight loss methods
  • Good mental health
  • Age 18 or greater

After your gastric sleeve surgery you will wake up in the hospital, a bit groggy and without a lot of pain. You may actually feel happy. This is usually due to the excellent pain medication your doctor has already administered but it’s also due, in part, to the sense of relief that comes from knowing that you’re done and safe.


Pain is typically moderate on the first day. You still have your IV in your arm and it’s easy to administer pain medication as needed. Be sure to communicate to your nurse or your surgeon what you need. Individuals respond to pain differently.

You will have 5 or 6 small incisions on your abdomen which will be sutured and covered to heal. The incision that typically causes the most pain is the site that the surgeon removed a large portion of your stomach. This is typically located in the lower left quadrant of your abdomen. It could also be on the right side. Look for the largest incision.

At this point, you will be laying in a hospital bed so you may just feel a general sense of soreness across your abdomen. You may experience residual nausea from the anesthesia but this should improve quickly.


Nothing by mouth at this point. Some surgeons allow their patients to have mouth swabs. Others, allow a cup of ice every few hours. You’ll probably feel dehydrated and want to drink something, but you likely won’t be able to do this until the following day.

Your throat is going to be sore and swollen from the ET tube (breathing tube during surgery) so its not pleasant to eat or drink at this point anyways. You will be exhausted and while you might worry that you’ll be hungry, its likely that you will not be hungry. Part of your stomach has been removed and your hunger causing hormone (ghrelin) levels are likely low.


Your surgeon in Tijuana surgery center in Mexico may actually want you up and walking. This is often to help reduce pain that can result from the CO2 used during laparoscopic surgery. When you aren’t walking, you’ll mostly be on your back with a slight incline on the hospital bed.

Getting out of bed the first day is difficult. Its almost like exercising a sore muscle. It will hurt. The more you are out of bed and walking, the better you will feel the following day.

Mental Stage

The first day is full of a variety of emotions. You’ve undergone a complete change of life, forever. Food has been a lifelong friend, a companion, and a stress reliever. Many patients will ask themselves, “Did I do the right thing?” or, “What did I do to myself?”

Day 1 After Surgery

You’ve probably had a somewhat restless night that included a lot of channel surfing while dozing in and out of sleep. Today, your radiologist will administer a swallow test to make sure there are no major leaks before your surgeon will allow you to drink water!

You will likely be visited by many people today including nurses, residents, students, surgeons, dieticians, discharge coordinators, physical therapists, and internists.


Pain is typically more noticeable at this point. The anesthesia has worn off and while your pain medications are working, you’re also moving a bit more. When you turn your trunk, pain is evident. Assuming your case was laparoscopic, your pain should be bearable. Different positions will offer different levels of comfort. Your throat is sore, swollen and dry; another source of pain but the small sips of water help.

You will be expected to use the IV pain medicine less and use oral medications more. The IV pain medicine works faster than the oral, so do not wait until the pain is unbearable to ask for the nurse to give you something by mouth.


You can drink clear liquids. Go easy but enjoy. At this point you may or may not be hungry. Many people are still not hungry at this point. But almost everyone is dehydrated and thirsty.

Follow the diet that your surgeon recommends. Most surgeons will allow for the following foods at this point.

  • Broth
  • Unsweetened juice
  • Milk
  • Strained cream soup
  • Sugar-free gelatin

Drink only small amounts of food at this point. Do not drink any carbonated beverages and nothing with caffeine. Caffeine has a slight diuretic effect and one of the major reasons for readmissions after these operations is dehydration.


You may be carted around for your swallow test in Radiology (which is usually in the basement of most hospitals). After your swallow test, your doctor should meet with you again. At this point he’ll probably check your pain, remove your catheter, make sure you can get up and on your feet and answer any questions you might have. A few hours later, your surgeon should discharge you with care instructions for your wounds and prescriptions for pain medication. Make sure you get these filled. Head home and read over your post-operative instructions.

Family Members

You are likely to be surrounded by some loving, well meaning, but completely bewildered family members. Unless they have previously undergone weight loss surgery, they will have trouble understanding your pain, your diet, your emotional liability, and your journey. Ask them to participate as much as possible. Have them present during the discharge planning, the dietician visit, and show them how to help you use this tool properly. The stress you are going through physically and mentally will take its toll on them too.

Day 2 & 3 After Surgery

Woman jogging. You are most likely on your own at this point. Your surgeon has discharged you from the hospital. That team of people that you had to help is now gone. Your spouse, family, or friend that has taken good care of you may be back at work. You have to do the heavy lifting. And, you may miss the pain pump or the IV administered pain medications that seemed to work better at the hospital.


Pain is still bearable for most people. Patients often experience the most pain between days 3 and day 6. This is typically because you are up on your feet more, turning your trunk more, and generally more active than before.

Typically, people report a pain in the range of 5/10 with some people’s pain getting up to a 7/10. Your doctor should have given you instructions regarding pain at this point as well. If the pain is unbearable or not what your surgeon told you to expect, you should let your surgeon know.

Most of your pain is restricted to the port sites (little incisions on your belly that are probably covered with a small dressing). The biggest port usually causes most of your pain. This is the incision where the surgeon removed the resected portion of your stomach. This incision is often stretched to get the stomach out and that stretching can result in more pain and bruising at this location.

Pain should slowly improve each day. Pain that is associated with vomiting, fever, new pains in the shoulder or back, and pains that don’t respond to oral pain medicine, are all reasons to call you surgeon.


Always continue to follow the diet your surgeon has given you. That diet may still just be clear liquids and the possible protein shake. After your doctor clears you from the clear liquid diet, you may be able to start on pureed (mashed up) foods. You will likely eat these soft pureed foods for two to four weeks. This diet includes foods that have the consistency of a smooth paste or thick liquid. There should be no solid pieces of food in the mixture.

Foods that blend well are typically recommended. These include:

  • Lean ground meat
  • Beans
  • Fish
  • Yogurt
  • Soft Fruits

And it helps to blend the solid food with liquids:

  • Water
  • Fat-free milk
  • Juice
  • Broth

Remember to stay hydrated. Your body is used to getting a lot of fluids from food which it will no longer be getting. Stay hydrated and if you’re diabetic be sure to check your sugar levels on a regular basis. Your diabetic medications have likely been reduced as part of your discharge plan. Right now, a sugar of 150 is much better than one of 55.


At this point, you will probably start to feel exhausted. Your diet is limited and your body is not used to the limited number of calories. Its also just been through a major surgery. A lot of your body’s energy is focused on recovery.

As always follow your doctors guidelines. As it pertains to activity, this mostly includes rest. Some doctors will want you walking a few times a day around the house. Keep your activity limited. You won’t have the energy for much more.

Climbing stairs is acceptable, but step every few seconds. Don’t carry anything up or down the stairs with you. Driving is not permitted while taking narcotic pain medication. Lifting is permitted, as long as it is something you can comfortably lift with one arm.

Week 1 & 2 After Surgery

Some people are ready to get back to work after week 1. Most people are still in too much pain when they twist and turn to think about work. And, surprisingly, many people say they are just too tired to work. Their bodies are still adjusting to the new food regimen.


Pain should not be severe. It should be tolerable but probably nagging. It will be most noticeable when you start to do errands, like getting in and out of your car.


You probably hate your blender at this point. But your diet hasn’t changed from the pureed foods. Its very important to stick to the diet that your surgeon prescribes – this can be tough but absolutely necessary. Eating solids such as nuts or fibrous vegetables could cause your staple line to rupture and you could leak. A leak is life-threatening. The good news is that you’ve already lost weight. And this should encourage you to stick to your new diet.

Its still very easy to become dehydrated, so drink your fluids.


Follow the exercise/activity regimen your surgeon has provided. This is typically not more than simple daily walks. In most instances, patients are encouraged to walk 3 to 5 times per day for 5 to 10 minutes at a time, gradually increasing the length of each walk as tolerated. Other forms of exercise are generally not recommended. Weight training is typically contraindicated at this point.

If returning to the gym is permitted by your surgeon, cut everything in half; half the time at the gym, half the speed/time on the treadmill, half the weights lifted and reps performed. Gradually work back to where you were pre-operatively.

Week 2 to Month 3

You’re back at work and you’ve already lost a good amount of weight. While some people still feel a bit tired, most people are encouraged by their weight loss, feel lighter and some have more energy than they did before surgery. You may need additional support during this stage. Your mood is likely to be up and down.


By month 2, you shouldn’t have much pain and you are probably off of all pain medications. If you’re still experiencing pain, make sure your doctor is aware of it.


After a few weeks of soft, pureed foods its time for a change. With your doctors approval, you can typically add soft, solid foods to your diet. These include:

  • Ground or finely diced meats Scrambled eggs.
  • Canned or soft, fresh fruit
  • Cooked vegetables

This diet usually lasts about 8 weeks or so before your doctor will clear you to eat solid foods. This diet is a big improvement over the soft, pureed foods only diet. Remember, you’re losing weight – stick to the diet. Aside from losing weight, you do not want to risk any complications.


Depending on your fitness level, your bariatric surgeon may approve increased activity (more than just walking) after 30 days. This may include swimming and low-impact aerobic exercise. For many patients, water aerobics can be a wonderful option. It is easy on the back, hips, knees, and ankles, and is very good cardiovascular exercise. It is worthwhile to investigate gym memberships at facilities that have a pool. Regardless of the exercise your doctor recommends, he/she will still likely ask you to stay at a low aerobic level where speaking is still comfortable.

Month 3 to 6 and Beyond

At this point you should be very glad you decided to have gastric sleeve surgery. You’ve started to lose a very visible amount of weight. You’re lighter on your feet and your surgeon has probably approved you for solid foods!


There should not be much, if any, pain at this point. If you still have pain, discuss this with your doctor.


After about 2 months, your doctor will probably approve solid foods. While this is very exciting, start slowly. You may find that spicy and/or crunchy foods can be difficult to tolerate. Eat one new food at a time and give yourself time to digest. You’ll be surprised at how full you will feel. This is a great opportunity to start new eating habits. Eat slowly. Enjoy every bite of your food. Check out our list of recommended books. Some of them offer great recipes for bariatric surgery patients.

You should have found, by now, a dietician to regularly follow-up with. This is important because they will know more about how to prepare meals for your family, how to strategize for trips to supermarkets/restaurants, and how to cope with large family dinners like Thanksgiving than your surgeon will.


Talk to your doctor about starting a more rigorous exercise routine. You’ll probably want to get into the gym or start a regular exercise routine. This is good but make sure your surgeon is aware of your routine. Most surgeons suggest waiting until about 6 months before adding weights into your exercise routine. Your aerobic exercise can be increased, and you’ll probably want to take longer and longer walks, and even jogs! Do not stop exercising. This is an important aspect of your new life. Every day is a new day. Whether or not you exercised yesterday or the day before, today you can make yourself a little healthier and happier.
