The internet is increasingly used as a source of medical information, not only by healthcare professionals but by patients as well. We describe the case of Patient A, a 32-year-old male with symptoms of sinusitis. He found a treatment on the internet and was informed when to consult a general practitioner. We also describe Patient B, a 31-year-old female with symptoms of fatigue after the delivery of her second child. Her search on the internet led to several referrals to a medical specialist due to her conviction that her symptoms were caused by a hormonal imbalance. We conclude that medical information on the internet can support both the doctor and the patient, or it can present an obstacle to proper communication during a consultation. Awareness by medical professionals of the Googling behaviour of their patients may be helpful in detecting the underlying question and worries of the patient.
