Vitamin D And A -Dry (Water soluble) Formulary

August 24, 2013 7:57 pm

Vitamin A and D are fat soluble vitamins. This means that in order for them to be absorbed by the GI track, them need to be absorbed by fat globules (chylomicrons). These are then taken up by the lymphatics of the GI track and taken to the blood stream. With the anatomical changes of the Duodenal Switch, the fat absorption capacity is significantly reduced. This results in excellent weight loss. It also results in much diminished absorption of the Fat soluble vitamins A, D, E and K. It is essential to use Dry Water Soluble forms of Vitamins A, D, E, and K.  Bio-Tech is a brand that is formulated in this manner.

We recommend specific dosages of dry (water soluble) Vitamin A and D. These are not available at most pharmacies. In fact when our recommendations are presented at most pharmacies they are incorrectly dispensed with the fat soluble variety with is worth less becasue it is not absorbed by the duodenal switch patients.  It is also important to not that this type of vitamin should not be taken with any dietary fat.  Fat can inhibit the absorption of this type of vitamin. When ordering online, please make sure that the “Dry” or “Water Soluble” formulary is ordered.




Bloating and Excessive Gas

April 17, 2012 7:36 am

The relationship between the consumption of food, bloating, and excessive gas is a subject that comes up frequently. In our practice, this is a complaint usually raised 3 or 4 years after receiving the duodenal switch operation. It appears that patients eventually disregard the recommendations made for a healthier diet of low carbohydrate, high protein, hydration, supplements, and then everything else.

In general, carbohydrates, carbonated drinks, artificial sweeteners (such as Splenda®, sugar alcohols, etc.), vegetables, excessive amounts of food, and an intake of fat will cause significant gas and bloating. This is not to be taken out of context and assumed that one cannot consume any of these products. However a diet that has fruits and vegetables will cause significant gas and bloating. These can not be controlled by probiotics, antibiotics, or other products such as Beano.

Simple carbohydrates/sugars (sugar, candy, cakes, cookies, pies, regular soda pop, jelly, jam, syrup, ice cream, sherbet, and sorbet, etc.) are easily absorbed. Simple carbohydrates/sugars can increase diarrhea due to the Duodenal Switch allowing more undigested sugars/fuel for intestinal bacteria to feed upon, multiply and form gas. The end result can be gas, bloating, and diarrhea.

Complex carbohydrates have more structure than simple carbohydrates/sugar which are harder for the intestinal bacteria to break down and may cause less bloating, gas and diarrhea. Also, complex carbohydrates usually contain higher fiber content.  The fiber in the colon will help to absorb water from the stool and can reduce diarrhea.  However, this is not the case for all Duodenal Switch patients.

When a patient reports these problems, I recommend that the consumption of all carbonated drinks should be stopped. No patient should consume carbonated drink of any sort. Artificial sweeteners should also be avoided all together. A good alternative would be honey, maple syrup or Stevia. Minimize or reduce the carbohydrate intake.

It has been our experience in the majority of cases that excessive gas and bloating is a result of dietary indiscretion. In some patients, once the dietary sources have been ruled out, it should be further evaluated by a barium enema to rule out the diagnoses of a redundant colon.

The best approach would be to first go back to a high protein and low carbohydrate. This should allow a patient to rule out any dietary sources for the bloating and excessive gas. It is recommended to next be seen by your physician for a further workup.

To summarize, when a patient has excessive amount of gas, diarrhea and bloating, the first line of treatment is elimination of all of the possible causes. These include carbohydrates, fruits, vegetables, artificial sweeteners, carbonated drinks and milk products. I can not overemphasize the importance of this step prior to anything else such as antibiotics or probiotics.
