7 Days of Diarrhea, Dizziness, and Near Fainting: Possible Causes?

I'm concerned about your symptoms, especially given their duration and the recent episode of dizziness and near-fainting. Your situation requires prompt medical attention. Based on your description, some possible conditions could include:

• Severe dehydration from prolonged diarrhea
• Viral or bacterial gastroenteritis
• Inflammatory bowel disease (like Crohn's or ulcerative colitis)
• Parasitic infection
• Food poisoning or intolerance
• Medication side effects

The dizziness, weakness, and near-fainting episode you experienced are particularly worrying as they could indicate severe dehydration or electrolyte imbalance, which can be life-threatening if left untreated.

I strongly recommend seeking immediate medical care, either at an urgent care center or emergency room. You need a proper evaluation, likely including blood tests and possibly stool tests.

In the meantime, try to stay hydrated with water and electrolyte solutions. Avoid dairy products, caffeine, and alcohol.

Remember, prolonged diarrhea and symptoms of dehydration are serious. Please don't delay in getting medical attention. Your health and safety are paramount. Take care, and I hope you get the care you need soon.
