Hi. Thanks for your query. Distended stomach can cause lots of restlessness, difficult in breathing and pain in the abdomen. Plan of action as you asked for is :: -Continue Syndopa Plus and Syndopa CR as before as this is a must for the control pf Parkinsonism. -Get an X-ray of the abdomen in standing position. This will help to see which part is distended to plan a treatment and further investigations accordingly. -Barium meal and follow through to see the interior of the stomach and intestines. -Upper GI Endoscopy to see for ulcer / cancer / duodenal stricture. -CT scan of the abdomen. -Tests of blood- particularly for Diabetes and Hypothyroidism which can cause this problem. - -Treatment plan. Start with prokinetic like Domperidone. Find the cause and treat according to the reports. Reduce the stress and anxiety as these are one of the most important causes of your problem. Avoid foods and beverages which cause gases and increase the problems.
