Carbonated Drinks and Weight Loss Surgery

August 11, 2012 3:56 pm

The consumption of carbonated drinks is discouraged after weight loss surgery. In fact, there is a wealth of information that documents the detrimental health effects of carbonated drinks for each individual. These include osteoporosis, obesity, and premature dental decay, just to name a few.  Indirectly, carbonated drinks have been found to increase risk of stroke and Cardiac events. There are studies that show a 48% increase in heart attack and stroke rates for individuals who drink diet sodas vs. those who drink it rarely or not at all.

There is also no health benefit to diet carbonated drinks.  In fact, there are animal studies that show that rats who consume no-calorie sweeteners found in diet sodas experience an increased appetite (Susan Swithers, PhD- 2004).

There are also other factors to consider. The carbonation comes from a mixture of dissolved gasses that are released when the container is opened.  The Carbon Dioxide gas dissolved in the drinks, amongst others, can distend the stomach. Potentially, stretching your stomach. There is also acidity that needs to be corrected by the body. This has been shown to result in changes in the bacterial population in the GI track, resulting in significant bloating and reduced absorption of nutrients.

Calcium loss is caused by the leaching of the calcium from the bones with carbonated drinks, which can cause osteoporosis.

Nasal Methicillin Resistant Staphylococcus Aureus Predicts Site Infection In GI Surgery

August 06, 2012 12:27 am

Dr. Papaconstantinou of White Memorial Hospital in Temple, Texas has studied the relationship between the presence of colonized nares with Methicillin Resistant Staphylococcus Aureus (MRSA) and the incidence of the type of the infection after a gastrointestinal surgery.

He studied 1137 patients. He compared the postoperative infection rate of patients that were positive for MRSA, Negative for MRSA and a third group that was Methicillin Sensitive Staphylococcus Aureus (MSSA). He found that the infection rate for MRSA group was 14%, the highest of all the groups. There was no correlation however when other risk factors were accounted for.

The most significant finding however was the type of the infection present in MRSA patients. With positive nasal swab for MRSA, the most common organism causing the wound infection was MRSA (70%). In patients that were MRSA negative for the nasal swabs, the rate of MRSA wound infection was low at only 8.5%.

An additional finding was that the finding of MRSA positive nasal swab was a predictor for prolonged hospitalization.

There was no reported difference in the postoperative death rate in the MRSA positive or negative group.

It is important, however, to remind ourselves that this is a single study and more studies are needed to look at these variables in different surgical procedures.
