Sulfur burps and diarrhea can be caused by various factors, including:

• Food and drink-related causes: Certain foods and drinks can cause sulfur burps and diarrhea, such as broccoli, brussels sprouts, cauliflower, garlic, dairy products, milk, beer, and carbonated drinks.

• Gut infections: Infections in the digestive system caused by H. Pylori bacteria and Giardia parasites can lead to sulfur burps and diarrhea. Other symptoms of these infections include stomach cramps, nausea, vomiting, and bloody diarrhea.

• Indigestion: Eating foods rich in sulfur or indigestion can also cause sulfur burps and diarrhea.

• Chronic disorders: Chronic disorders such as irritable bowel syndrome (IBS) can cause sulfur burps and diarrhea.

To alleviate the symptoms of sulfur burps and diarrhea, you can try the following:

• Drink more fluids such as water, diluted fruit juice, or flat soda to avoid dehydration.
• Sip on ice chips if you cannot hold the fluids down.
• Avoid greasy and spicy foods that may be causing the problem.
• Eat bland foods such as potatoes, noodles, rice, toast, cereals, or crackers that do not stir the stomach.
• Keep a food diary to identify the specific triggers of sulfur burps and avoid them.
• Consult a gastroenterologist for proper diagnosis and treatment if your symptoms are consistent with H. Pylori or Giardia parasite and do not seem to be improving, or any new symptoms develop.
