Hello, I’ve Been Sick For About Two Weeks Now.. I
Thank you for trusting "Ask A Doctor" service for your query,
The symptoms you are describing are mostly suggestive Gastroenteritis, which is the infection and inflammation of the intestine.
Stool analysis and culture are required to confirm the diagnosis. Management is with antibiotics (usually a combination of Ciprofloxacin and Metronidazole) for which you will need a prescription. So please be advised to follow up with the urgent care.
Meanwhile, drink plenty of water and electrolyte-containing drinks like Gatorade for overcoming weakness and dizziness.
Follow a soft diet. BRAT (Banana, Rice, Applesauce, and Toast) diet will be easier on your tummy to digest.
For loose stools take Imodium 4mg three times a day.
You can also take Buscopan 10 mg thrice daily for controlling loose motions.
Hope this answers your query
Please let me know if you need further clarification
