Before surgery, every patient must have several pre-op studies, have a psychological evaluation, and, in some cases, a psychiatric evaluation. You will also need a complete pre-op evaluation by internal medicine, endocrinology or cardiology. It is important that you understand what happens before, during, and after the surgery.

Pre-Op Diet Plan and Its Importance

According to Dr. Rey Romero and his multidisciplinary team’s experience, along with several publications that remark it, before any bariatric procedure, you will have to follow a special pre-op diet plan. The number of days needed to complete this plan will vary according to your Body Mass Index (BMI).

Generally, a patient with 30-40 BMI should have a 3-day diet plan; patients with a 41-45 BMI, a 5-day diet plan and patients with a 46-55 BMI a 7-day diet plan. In some cases, patients could require a 10-day diet plan. Remember that everyone is different and the number of days required will be determined by our dietician, by a previous evaluation and your medical record.

The diet plan before your surgery is extremely important for a successful outcome. Sticking to the diet plan is fundamental because it causes a fast abdominal weight loss, which reduces the size of the liver and the fat in the abdomen. These changes cause a bigger space inside the cavity, which makes it easier for us to have a better vision and thus an easier technical procedure.


How does this benefit the patient?

When the diet plan is followed, the procedure is easier. Additionally there are several benefits for the patient:

  • Fewer incisions needed, since fewer instruments are required.
  • Fewer incisions also mean better esthetic results.
  • With fewer incisions, there is less post-op pain.
  • Complication rate is reduced (bleeding, intra-abdominal organ injury).
  • Surgical time is reduced, which means less anesthesia, nausea and discomfort after the procedure.
  • All of this means a faster recovery


What would happen if I do not follow the diet plan?

First of all, we strongly recommend that you follow the diet plan as instructed, since this is a fundamental step. If you do break this diet plan, as little as it may seem to you, you need to let someone in our team know, so we can evaluate if the plan needs some adjust or the surgery to be rescheduled.

Note that if we need to reschedule your surgery or even to cancel it because you did not follow the recommended diet plan, we cannot assure that we will be able to issue a full refund. This is why you should follow this diet plan exactly as recommended. If you think you will not be able to follow it, we could hospitalize you a few days before your surgery to help you complete this plan adequately. Remember, you can always talk to anyone of our team members. We will be happy to assist you.



Can I smoke?

You should not smoke 10 days prior or 1 month after surgery. If you can abstain from smoking for a longer period of time, it would be so much better. This is important because smoking inhibits a correct tissue healing, which increases the risk of complications such as leaks. It also increases the risk of thrombus and some other lung problems.

What medications am I able to take before surgery?

Ten days before surgery, you must inform your surgeon or our Medical Coordinator what medications you are on, so we can make you a list on the ones you can and cannot take. You must stop taking any dietary or vitamin supplement at least 10 days before the surgery because they could interfere with proper coagulation during the procedure.

To sum up, everything you take the previous 10 days of your surgery must be reported to our team.

Can I exercise before surgery?

Yes, you may take short walks or do some stretching. But 10 days prior to surgery, you should avoid great physical exert like sports, running, swimming, or any other heavy activity. Otherwise, you could have an inadvertent injury that could prevent us from performing this procedure.

Is alcohol allowed?

It is strictly prohibited to drink alcohol 10 days prior to surgery, not even wine. It is also prohibited for at least two months after the surgery. After this period, you will be able to drink it in a controlled and restricted manner.

What should I do the day before my surgery?

Relax. Take a walk. You could visit a museum, sit on the beach, or go to the movies. You could just stay at home or at your hotel and watch a movie or do some office work. If you decide to go to work, we suggest that you stay away from temptations. Remember that it is fundamental to follow your diet plan. If you have any skin problems, be sure to let your surgeon know.

If you are from another city, you will probably have pre-op studies and a scheduled doctor’s evaluation (internal medicine and psychology). If this is the case, make sure to wear comfortable clothes and fast for six hours. We will pick you up at your hotel and take you to the hospital for your studies and evaluations. You will be in constant communication with our coordinator (by phone or WhatsApp).

The day of the surgery, we will pick you up from your hotel and take you to the hospital. After you are discharged, we will take you back to the hotel and once you are ready to go home, we will take you to the airport or bus station.

As you can see, you will not be alone for one second. There will always be some member of our team with you.

The day before surgery, try to wake up early, so you can go to bed early and get a good night’s sleep. If you are nervous and cannot sleep well, you could try taking 5mg-tablet of Melatonin or two 3mg- tablets, 15 minutes before going to bed. In Mexico, you can buy them at any drug store without a prescription. The most common branded commercial names are Benedorm, Normolem or Melatol.

When you wake up, do not drink or eat anything; if you normally take your hypertension or diabetes pills in the morning, you can take them with as little water as possible. You may wash your teeth but remember you may not swallow the water. Take a shower with your usual soap.

It is best if you arrive to the hospital an hour before the surgery. Remember that if you are from another city and you are staying at a hotel, we will pick you up at an established time.

Also, remember the more people involved, the better you will feel

  • We have seen that if your friends, family and relatives know about the surgery, the process may be easier.
  • There are both individual therapies and group therapy to help you to get through the whole process.
  • Whether you decide to tell your friends and family is completely up to you. However, you should take into account that we strongly suggest as well as other bariatric surgery institutions to tell the truth. Tell them that you have had the surgery! This will make everything easier (weight loss, less stress, avoid lies).
