<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Ive been having severe diarrhea and stomach cramps for the past two days.  <response>: It sounds like you have infectious gastroenteritis. I would recommend some medications to help alleviate your symptoms. You will need to take Antibiotic metronidazole to fight off the infection causing the gastroenteritis. Additionally, I suggest taking Loperamide Imodium to reduce diarrhea, Trimethobenzamide Tigan to relieve nausea and vomiting, and Bismuth Subsalicylate Pepto-Bismol to soothe the stomach. You should also include Sodium Citrate in your diet and take Lactobacillus Acidophilus and Bulgaricus pro-biotics to help balance the gut bacteria, and topical application of Sodium Hypochlorite to sanitize the affected areas. To manage dizziness, you should use Dimenhydrinate Dramamine. Lastly, Pepsin A will help digest your food, and Betamethasone will reduce inflammation.
