SIPS-SADI and ASMBS

December 31, 2023 1:21 pm

I was asked if my opinion of SIPS-SADI has changed since ASMBS endorsed it. Let me remind everyone that ASMBS also endorses Adjustable Gastric Banding. We know what happened to the story. Is anyone considering Lap Band, even though ASMBS endorses it? I am a member of ASMBS. The endorsement of the ASMBS does not unequivocally validate the outcome of a procedure; it only states that is an available alternative. As stated previously, patients should be clear that SIPS-SADI procedures are not Duodenal Switch operations. Any suggestion is misleading. The physiology of SIPS-SADI is very different than that of the duodenal switch operation. Complications are associated with them, as reflected by the revisions we do to convert them to a Duodenal switch with percentage-based measurement of the small bowel. In our practice, we have had to revise SIPS-SADI to duodenal switch operation due to compilation such as bile reflux gastritis and inadequate weight loss.

Weight Loss Injection

May 10, 2023 1:06 pm

Semaglutide (Ozempic, Rybelsus, Wegovy, Saxenda) and tripeptide (Mounjaro) treat type II diabetes. They work thru several complex pathways. An observed side effect that has been noted in diabetic patients has been weight loss.

Some have been advocating using the class of medications for weight loss. However, Wegovy is the only medication approved for weight loss in non-diabetic patients.

There is a lot to be discussed here:

1-the use of the medications for weight loss is an off-label use (except Wegovy)- meaning that the FDA did not approve the medication as a weight loss drug.

The practical implication is that the medication’s safety and complication profile in non-diabetic patients looking to lose weight may be unknown and has not been studied.

2-The medication has become available thru compounding pharmacies. It is crucial to appreciate that compounding medications do not meet the same rigor and standards and may, in fact, not be the same formula as the FDA has stated.. This also means that a compounding pharmacy does not approve the medications in several states.

3-The most critical issue for me is the lack of a “long-term plan.” It is not clear what would happen when the patient stopped the medication. Will the patient experience weight regain? Will the patient require higher doses of the medication to maintain the weight loss, or will the medication stop working altogether? Unfortunately, we do not have these answers. For those skeptical about my questions, let me remind you that phentermine has significant side effects, and almost all patients experience weight gain when they have to stop the medication because of the cardiovascular complication of medication.

Over the Counter Vitmain D3 better than the Prescription Vitamin D2

August 30, 2021 10:41 am

Vitamin D absorption is based on a complex series of pathways in the human body. We have discussed the significance of Vitamin D in a broad health condition, including Covid-19, immune system and bone structures. These articles explain the differences in detail. https://www.dssurgery.com/wp-content/uploads/2021/08/jcem5387.pdf https://www.dssurgery.com/wp-content/uploads/2021/08/jcemE447.pdf We have no finaicial insterst in the recommendations made on our site.

Sleeve Gastrectomy in Adolescent patients

September 23, 2020 5:44 am

The benefits of weight loss surgical procedures are undisputed. Over the last decades, as the incidence of obesity has increased, so has the need for effective long-term treatment options. It is no secret that diet and exercise plans are only short-term remedies since none of them provide realistic long-term alternatives. Let’s be clear that a healthy diet and activity level are critical to a healthy body and mind and to the long-term success of weight loss surgery. A frequent question: How young is too soon for weight loss surgery? We work with our patients to ensure that weight loss surgery will not affect the growth of an adolescent patient with regard to height, bone formation, and hormonal status. Specifically, there are concerns about a female patient’s ability to get pregnant and have children. All the scientific evidence points to the benefits of weight loss surgery and the improved ability to get pregnant and bear the pregnancy to completion. Weight loss positively impacts the ability to get and have a healthy pregnancy leading to a non obese child. An article recently published demonstrated the benefits of early intervention. Specifically, it showed the improved odds of resolution of diabetes in the younger patients  (100% in adolescents, Vs. 75% in adults ) at 24 months post-op. Sleep apnea resolved at the same rate. These early interventions can mean there may be lower long-term risk and associated conditions for these teens as they age. A recent article was written from several adolescent weight loss surgical patients’ perspectives: This included their feelings of hope for their futures and health.

Vitamin D and COVID 19

June 13, 2020 4:40 pm

There has been extensive discussion on the importance of Vitamin D published over the last few years in regards to bone health, immune health and Calcium physiology. The importance of vitmain D and bone structure has been discussed extensively. It is also important in the absorption of Calcium. It further plays role in immune modulation.

What is new is the possible correlation of Vitamin D and COVID 19. Recently it is been shown that low vitamin D may increase the risk of a poor outcome with Covid-19 exposure and infection.

There are different standard recommendation for the Vitamin D levels.

In our practice we aim to maintain a Vitamin D level of 0ver 60 in post weight loss surgical patients.

There are a number of theories as to how the Vitamin D deficiency may play a role in this. An emerging observation is that low Vitamin D may cause abnormal and excessive blood clot formation. Mohammad et. al. in 2019 published a study on the association of low vitamin D and “…Pathogenesis of Thrombosis”

This pathologic blood clot formation in COVID-19 patients may explain the extensive lung injury and  multi system organ failure in some patient. It is also one of the reason that some COVID-19 patients have loss limbs or appendages.

Please follow all supplement recommendations based on your laboratory studies and all COVID-19 recommendations. We would recommend frequent hand washing, surface cleaning, social distancing, and wearing face masks as the most basic precautions and increase precautions based on your health status.

Fat Soluble Vitamins

April 26, 2020 10:20 am

Written By: Maria Vardapetyan, Eric Baghdasaryan, Osheen Abnous

Vitamins are chemicals that facilitate many processes in the human body such as blood clot formation, good vision, fight infections etc. There are two classes of vitamins. Water soluble vitamins and fat soluble vitamins. Water soluble vitamins dissolve in water. This makes it possible for them to be absorbed through all mucous membranes. Fat soluble vitamins on the other hand do not dissolve or pass through mucous membranes. Fat-soluble vitamins are absorbed in the intestine along with fats in the diet. These vitamins have the ability to be stored in the fat tissues of the human body. Water-soluble vitamins are not stored in the body and have to be taken in daily with the food and dietary supplements. Solubility of a vitamin is not a function of its physical state. There are fat soluble vitamins that have a liquid form and almost all of the water soluble vitamins come in form of pills or powders.

In this article, we are going to focus on fat soluble vitamins. They are all complex molecules made of carbon, hydrogen, and oxygen in different arrangements (see figures 1, 2, 3 and 4). These fat soluble vitamins are vitamin A, D, E and K.

Vitamin A

Vitamin A has a major role in vision, immune function, cell growth, and maintenance of organs such as heart, kidneys, lungs, etc. It plays a pivotal role in the health of our eyes, specifically the retina1. Rhodopsin protein, a major protein that has the leading role in the process of vision, is found in the retina where it allows us to perceive light. This protein requires vitamin A to function properly. Without vitamin A, rhodopsin cannot sense light and thus cannot initiate the process by which vision occurs.

Vitamin D

Vitamin D regulates different chemical reactions that are associated with bones, muscles, and the immune system. The simplified way it does this regulation is it helps absorb calcium from dietary nutrients which in turn strengthens the bones, helps neurons exchange signals to move muscles and helps the immune system to fight against viruses and bacteria2. 

pastedGraphic_1.pngFigure 2: Chemical structure of Vitamin D molecule

Vitamin E

Vitamin E acts as an antioxidant. Antioxidants are naturally occurring chemicals that neutralize toxic byproducts of many chemical reactions in the human body. When food is consumed and digested, the human body converts it into energy. As a result of metabolism free radicals (toxic byproducts) are formed and are neutralized with the help of vitamin E. In addition, free radicals are also in the environment. Furthermore, vitamin E stimulates the immune system to fight against bacteria and viruses3.

Vitamin K

Vitamin K can be obtained from food and dietary supplements. There are two forms of vitamin K: phylloquinone (Vitamin K1), which is found in spinach, kale and other greens and menaquinone-4 (Vitamin K2), which is found in animal products. Vitamin K1 is involved in blood clotting, and Vitamin K2 is involved in bone tissue building. Vitamin K1 is the main Vitamin K in human diet (75-90% of all vitamin K consumed), however, it is poorly absorbed in the body4,5.

Absorption of fat soluble vitamins

Polarity describes the inherent charge(positive or negative) or lack of charge for any given substance or molecule.  Molecules that are charged are referred to as “polar”, while those that lack charge are “nonpolar”. When discussing solubility, it is important to remember the phrase “like dissolves like”. That means polar (charged) substances like to interact with a polar environment like water, since water contains a slight negative charge. Hence, charged substances are water-soluble. Nonpolar substances on the other hand readily interact with nonpolar environments such as fat, which contains no charge. Therefore, molecules that lack a charge such as vitamins A, D, E, and K are referred to as fat soluble. 

 

Due to their water fearing nature, these fat soluble vitamins cannot simply be absorbed directly into the bloodstream (which is mostly water) like the sugars and amino acids in our diet. As their name suggests, these fat soluble vitamins like to be embedded in fatty droplets, which facilitate their absorption in the following way. Fat soluble vitamins group together with other fat molecules to form fatty droplets, effectively reducing the amount of interaction with the watery environment of the intestines. Therefore, without an adequate amount of fat in your diet, your body is unable to effectively absorb these fat-soluble vitamins. This may be true in an intact anatomy, however, post weight loss surgical patients can not increase their fat soluble vitamin levels by increasing their fat intake. This is due to the fact that a high fat diet causes excessive bowel movement which in turn washes away any vitamins taken by mouth. DS limits fat absorption (thus the great weight loss) which can cause vitamin A and D deficiency that can not be easily corrected with oral supplementation.

As mentioned before, fat soluble vitamins are hydrophobic and nonpolar, which means they are also fat loving or lipophilic. Excess fat soluble vitamins can be stored in the liver and fat tissue. Therefore, these vitamins do not need to be eaten every single day since stores of these vitamins can sustain a person for some time. It may take several weeks or months for our body to deplete these stores of fat soluble vitamins which is why it generally takes a longer amount of time for fat soluble vitamin deficiencies to manifest themselves. The ability to store these fat soluble vitamins in tissues can also lead to vitamin toxicity – marked by an excess of vitamin stores in our body.

Vitamin D Metabolism and Deficiency file

March 28, 2020 8:17 am

It’s important to understand Vitamin D metabolism and deficiency potential following weight loss surgery Vitamins after DS need to be followed via laboratory blood studies. There are basic vitamin needs but individual needs should be based on medical history, genetics, alimentary limb length, common channel length and other surgical and physiologic determinations. Vitamins after DS are a life long commitment as well as protein needs and hydration. Duodenal Switch is a malabsorptive procedure which requires at least yearly laboratory blood studies, daily vitamins/minerals, daily high protein and daily hydration intake. There is not an all in one vitamin that is adequate for a DS patient or tailored to your individual needs. (example: you may need more Vitamin D and less Vitamin A if you are taking a all-in-one vitamin you can’t get more of one and less of another vitamin)

DS patients are recommended to take Dry forms (water miscible form) of Vitamin A, D3, E, K due to the fat malabsorption after DS. Dry formulations by Biotech are processed so they can be absorbed by a water soluble method after the DS procedure. Vitamin D seems to be the vitamin that can become deficient the easiest, followed by Vitamin A. Take these vitamins away from dietary fat.

In some cases, patients may need injectable Vitamin A or D to improve vitamin levels.
