My experience at Tijuana Bariatric was good from beginning to end. I would recommend their services if you are considering Bariatric surgery. ​A standout for me was Medical Coordinator Lanelle DeCaire. It was a pleasure to work with her.* View On Google +


With limited space in the stomach, it is often difficult to consume sufficient liquids. Because water plays such an important role in our body, the effects of dehydration can be catastrophic: not only can it lead to bladder or kidney infections, it can leave patients weak, dizzy, and confused. If you are experiencing lower back pain or notice deep yellow or amber urine, you may be dehydrated. Fortunately, there are a number of simple ways to ease this discomfort:

The average person needs at least 1.5 to 2 liters of water a day – about four bottles’ worth. If nausea makes drinking difficult, sucking on ice cubes can also be beneficial. However, patients should avoid drinking caffeinated beverages altogether.

Diarrhea and Constipation

Because your digestive system undergoes drastic changes, it can take your body a considerable amount of time to adjust after bariatric surgery. On the one hand, an altered diet and reduced caloric intake can cause patients to experience fewer bowel movements, which can make them more prone to constipation. But on the other hand, eating fatty or sugary foods can easily upset the stomach and cause diarrhea. Unfortunately, both side effects are particularly common. Patients should only become concerned if an individual episode lasts more than two days.

We Can Help You Prepare

Handling the side effects that result from bariatric surgery can be overwhelming, but the doctors and nutritional counselor working through the Tijuana Bariatric Center can help you prepare for any potential complications. Contact the center today to take advantage of our support and learn more.*
