I'm taking ranitidine for acid reflux and my doctor mentioned I should take it twice a day, but she didn't specify how many hours apart. The capsules are 150 mg each. Could you tell me when exactly I should be taking them? I've tried looking it up online but didn't find a clear answer.

For optimal effectiveness, you should take the 150 mg ranitidine capsules about 12 hours apart. This means taking one dose in the morning and another in the evening, ideally after meals or as directed by your doctor. If you're unsure, it's always a good idea to check back with your doctor for specific timing instructions.

My endoscopy impression LAX LES. Narrowing noted at D1 D2 junction. Scope could not be passed beyond. BC taken. Doctor suggested bypass surgery.

The endoscopic finding of a narrowed area at the D1-D2 junction (duodenal junction) and the inability to pass the scope beyond this point suggest a potential blockage in the duodenum. The doctor's recommendation of bypass surgery likely refers to a surgical procedure to create a new pathway for food and fluids to bypass the obstruction, potentially a duodenojejunal bypass. This could be necessary to relieve symptoms like nausea, vomiting, or abdominal pain caused by the blockage
