Gas and bloating can still occur even without oily food due to slow digestion, eating habits, stress, or certain foods that produce more gas. Try eating slowly and chewing well so less air is swallowed, and take smaller meals at regular times to keep digestion steady. Avoid foods that commonly cause gas, like beans, cabbage, fizzy drinks, and very heavy meals, and stay active with a short walk after eating to help gut movement. Drinking warm water throughout the day can also ease bloating. Notice if symptoms worsen after specific foods or during stress. Consult a doctor if it keeps troubling you or becomes severe.
