Vomiting and loose motions since morning are commonly caused by stomach infection, food poisoning, viral illness, or indigestion, and the most important thing is to prevent dehydration. Drink plenty of fluids in small amounts frequently, such as ORS (oral rehydration solution), clean water, coconut water, rice water, or clear soups, because the body loses a lot of water and salts through vomiting and diarrhoea. Avoid oily, spicy, heavy, or outside food for some time and eat light foods such as bananas, curd, rice, toast, khichdi, apples, or boiled potatoes once vomiting starts settling. Rest is also important to help the body recover. Probiotics may sometimes help improve gut balance and reduce diarrhoea, while medicines for vomiting or stomach cramps may be needed in some cases under medical guidance. Avoid taking antibiotics on your own because many stomach infections improve without them, and unnecessary use may cause side effects. You should seek medical attention if you develop a high fever, severe stomach pain, blood in stools or vomit, dizziness, reduced urination, severe weakness, repeated vomiting preventing fluid intake, or if symptoms continue beyond a couple of days, as these may indicate dehydration or a more serious infection. Most mild cases improve within a short time with fluids, rest, and proper diet.
