Gastric disorders play an important role in digestive system of a human subject. Gastric disorder is due to the gastric dysmotility due to delayed gastric emptying and other motor dysfunctions like impaired fundic distention. Nowadays invasive technique like laparoscopy procedure, endoscopy procedure and surgery procedure plays a vital role in investigation of gastric disorders. Electrogastrogram is a noninvasive technique for analyzing digestive system disorders. In this proposed work, stimulation is delivered with the electrode package with camera, which travels through an esophagus to reach stomach and stimulate the interstitial cajal cells. Due to this stimulation the stomach starts, its activity a potential is provided that is recorded with electrode setup, which is called electrogastrogram. It is verified with its normal range 3 cpm. The stimulation includes pulses mode and continuous mode. Stomach function is recovered and its frequency is measured and the same is compared with normal range value. Depending upon the subject condition, the gastric activity is improved by setting different values of duty cycle. By this procedure the subject avoid painful procedure, stay in hospital, frequently and the cost is minimum.
