The frequency of Internet use for self-directed medical care in different patient populations is increasing. We evaluated Internet use by patients presenting for bariatric surgery.

Surveys were completed by 136 patients (109 women, 22 men) presenting to a private academic clinic for bariatric surgery. Data collected included age, gender, education level, household income, and pattern of Internet use. Comparisons were made with a group of 135 patients who visited a colorectal surgery clinic in the same institution.

Bariatric patients who used the Internet were more likely than colorectal patients to inform themselves about their medical problem (76% versus 49%, p < 0.001) and tended to use the Internet more overall (85% versus 78%, p = ns). Use of the Internet to research bariatric surgery was associated with education level (p = 0.002) and household income (p = 0.01), but not with age or gender. Bariatric patients were more likely than colorectal patients to search our institution’s Web site (40% versus 17%, p < 0.001) and to use the Internet to find out about their surgeon (47% versus 31%, p = 0.01). Only 9% of bariatric patients used a chat room. Ninety-six percent of bariatric patients found the information on the Internet easy to understand and 58% described it as very helpful.

Bariatric patients are especially likely to use the Internet to gain information about their medical condition, possibly reflecting their limited mobility. This represents an educational opportunity for the surgical community.
