Restrict Caffeine After Bariatric Surgery

NutritionRestrict 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 the gastric sleeve. 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 individuals. 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.
