Vomiting, diarrhoea, and excessive gas are most often due to a stomach infection or food-related irritation, and the main focus is to prevent dehydration. Start taking oral rehydration solution (ORS) in small, frequent sips, drink plenty of fluids like water or coconut water, and eat light foods such as rice, curd, and bananas while avoiding oily, spicy, and outside food; rest well and avoid self-starting antibiotics, though a doctor may suggest medicines to control vomiting or probiotics if needed. Most cases improve within 1-2 days, but you should seek medical care if symptoms are severe, persist beyond 2 days, or if you notice warning signs like high fever, blood in stool, inability to keep fluids down, or reduced urination.

Having loose motions for a month is considered chronic diarrhoea. Since temporary medication didn't cure it, we need to find the root cause rather than just taking another quick-fix medicine. It could be due to a persistent infection, food intolerance, or gut inflammation. Please do not self-medicate with antibiotics. Instead, consult a doctor who will likely recommend a stool test to pinpoint the exact cause. For immediate relief and safety, stay well-hydrated with Oral Rehydration Salts (ORS) and consider taking a generic probiotic to help restore your healthy gut bacteria. Rest assured, this is very treatable once the correct cause is identified.
