Have gastropatesis and my t 1/2 time is 345min. what is the t 1/2 time on a gastric emptying study and how bad is a t 1/2 time of 345 min? appt in am.

Time for 1/2: The t 1/2 is the time it takes for your stomach to empty half of its contents. The normal value is approximately 120 minutes.

Slow: Gastroparesis, delayed gastric emptying, is a medical condition resulting in food remaining in the stomach for a longer time than normal.Cause include neuropathy, diabetes, connective tissue disorders, and eating disorders.Treatment includes change in diet and some medications. Should see doctor for advice and treatment. 345 min. Is slow gastric emptying.

It's complicated...: Each institution has its own standard meal ; imaging protocol for gastric emptying studies. Each institution also has it's own normal database to compare to. Therefore, there is no exact number for normal t1/2. It depends on the meal and normal database for that institution. Currently a newer standardized meal / protocol is being implemented so values can be compared across institutions.
