Information was received from a friend/family member regarding a patient who was implanted with an implantable neurostimulator (ins) for gastric stimulation.It was reported that the patient was doing well for about 4 years.The patient was up to they thinks (b)(6) pounds.In (b)(6) 2020 it seemed to have stopped working, and they went to the doctor and they recalibrated it 3-4 times.They went back to the doctor a couple more times to the surgeon. they then went to a new doctor and that doctor calibrated it once.The patient has been able to see a flutter in her stomach since they got the implant.If she puts a quarter on their stomach their can see it move or flutter every four minutes since the return of symptoms, and then the fluttering stopped and just happened once and a while.Prior the patient could see their stomach move more frequently.The second doctor saw the flutter or moving of their stomach and said it was not supposed to be able to feel the stimulation or see their stomach moving that something was wrong.Caller wanted to know if that was true because they are getting conflicting answers.Patient has lost (b)(6) pounds in the last six months and was down to (b)(6) pounds and has vomiting.No x-ray had been performed.They never mentioned anything about how to read the battery level so they don't know.It was explained that if the battery was low or dead they could have return of symptoms.They had not had any falls or accidents but was not aware of but will ask the patient.The issue was not resolved through troubleshooting.Representative stated that most patient's don't feel the stimulation but they can report they feel the stimulation and typically don't see stomach movement but due to the nature of stimulating a nerve and the stomach it is not to say it can't happen.Recommendations to determine the issue could be x-ray, run impedances, and check battery level of stimulator.
