Restrict Caffeine After Bariatric Surgery

People who are morbidly obese may choose bariatric surgery as a means to lose excess weight. Surgical approaches for weight loss surgery include gastric bypass, Roux-en-Y, laparoscopic adjustable gastric banding or a gastric sleeve surgery. Each type of surgery poses special dietary restrictions after surgery. Limiting certain foods and beverages is necessary to prevent postsurgical complications.

Effects of Caffeine

People who have had this type of surgery are at risk of dehydrating due to the need to limit liquids at mealtimes, often making it difficult to consume the necessary amount of liquid per day. Caffeine also inhibits the absorption of iron and may contribute to iron deficiency anemia. Caffeine increases the amount of gastric acid in the stomach, causing acid reflux for some iniduals. This is one of the reasons why patients should restrict caffeine after bariatric surgery.

Beverages High in Caffeine

Many beverages contain caffeine but differ in amount depending on product and brand. Usually, a regular 8-oz. cup of coffee ranges from 100 to 200 mg of caffeine. Tea contains 18 to 120 mg of caffeine per 8 oz. Soda contains 23 to 71 mg of caffeine in each 12-oz. can. Energy drinks vary from 74 to 160 mg of caffeine per serving.

Other Sources of Caffeine

Food and medicine may also contain caffeine and should be limited in the postsurgical diet. Chocolate may contain 9 to 31 mg of caffeine per oz. Dark chocolate contains more caffeine than milk chocolate. Coffee-based ice cream contains 58 to 84 mg of caffeine per 1/2-cup serving. Medication such as Anacin, Excedrin and No-Doz contain up to 200 mg of caffeine per dose.

Special Considerations

Products that are labeled decaffeinated may still contain caffeine. For example, decaffeinated coffee and tea contain 2 to 12 mg of caffeine per 8 oz. Green tea may contain upwards of 25 mg of caffeine per cup. If you have questions, contact Obesity Control Center in Tijuana Mexico today.

OCC’s epidemiologist is closely monitoring the COVID-19 status and is actively issuing updates as they are available. The Centers for Disease Control and the World Health Organization are the most trusted sources online.  While the CDC has announced new mask protocols for vaccinated individuals, there will be no changes for our office protocols for patients, guests, and staff members as the announcement does not apply to hospitals or medical facilities. Masks are still a requirement for all patients, guests and staff at our facility.

As we reinitiate weight loss surgery, we are constantly adapting and installing new and updated safety measures.

Bariatric Surgery and the clash of two pandemics.   

Major metabolic and bariatric surgery Societies and colleges globally are now calling for the safe resumption of bariatric and metabolic surgery before the COVID-19 pandemic is declared over. 

The sooner bariatric surgery can be safely performed, the quicker obesity, type 2 diabetes, and other diseases can be reduced or resolved as they are not only chronic they are also progressive.  Obesity is also linked to more than 40 diseases including type 2 diabetes, hypertension, heart disease, stroke, sleep apnea, osteoarthritis, and at least 13 different types of cancer.

A recent statement from the ASMBS says “Before COVID-19 began, it was clear that patients with obesity were ‘safer through surgery.’ In the era of COVID-19, ‘safer through surgery’ for patients with obesity may prove to be even more important than before.” Obesity and Metabolic syndrome have been identified as an independent risk factor for adverse outcomes including death among COVID-19 patients.
