Gas formation along with vomiting, dehydration, and weakness is commonly caused by stomach infections, food poisoning, indigestion, acidity, contaminated food or water, or a viral illness affecting the digestive system. Vomiting and poor intake of food or fluids can quickly lead to dehydration, which may cause tiredness, dizziness, dry mouth, low urine output, and weakness. To help recovery, the most important step is to drink fluids slowly and frequently, such as ORS (oral rehydration solution), coconut water, rice water, lemon water with a little salt and sugar, or plain water in small sips if vomiting continues. Eat light and simple foods like rice, bananas, toast, khichdi, curd, apples, or soup, and avoid oily, spicy, heavy, or outside food until you feel better. Rest is also important because the body needs time to recover. Avoid taking medicines for vomiting, gas, or antibiotics on your own without medical advice, because the treatment depends on the exact cause. If you develop severe stomach pain, high fever, blood in vomit or stool, inability to keep fluids down, confusion, reduced urination, chest pain, or symptoms lasting more than one or two days, you should see a doctor immediately because dehydration and stomach infections can sometimes become serious. In many mild cases, proper hydration, rest, and careful eating help symptoms improve gradually within a few days.

Stomach infection with loose motions and pain is often caused by a food or water-related infection. It is important to stay well hydrated, take light meals, and maintain hygiene to prevent worsening. Avoid self-medication and do not take any medicines without proper advice. Consult a doctor to get the right treatment based on your condition.
