Causes of hiccups in adults

A hiccup is a reflex spasm involving the diaphragm and vocal cords. A full stomach, rapid eating, fizzy drinks, alcohol, spicy food, laughter, stress, or sudden temperature shifts can start a short episode. Ongoing hiccups may occur alongside [Acid Reflux](/conditions/acid-reflux/) or [Gastritis](/conditions/gastritis/); these conditions present with hiccups in some people, often alongside burning, nausea, bloating, or upper-abdominal discomfort. Medicines, chest or abdominal irritation, and problems affecting the nerves or brain can also be considered when episodes are prolonged or accompanied by other changes.

Eat slowly, use smaller portions, and avoid fizzy or alcoholic drinks during an episode. Remain upright after meals and take calm breaths rather than repeatedly forcing a breath hold. Note the timing, recent foods, medicines, and symptoms such as heartburn or pain. A clinician may review your medicines and examine your chest, abdomen, or nervous system if hiccups continue. Do not borrow prescription treatment. If reflux is suspected, ask whether [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) fits your health history.

Book an appointment if hiccups recur often, last long enough to affect sleep or meals, or accompany persistent reflux, vomiting, trouble swallowing, abdominal pain, or unexplained weight loss. Get urgent help if they occur with difficulty breathing, severe chest pain, confusion, new weakness, or a sudden severe headache. The urgency comes from these associated warning signs, not from hiccups alone.

Ask whether your pattern suggests a digestive trigger, a medicine effect, or another source of irritation. Tell the clinician when the first episode began, its longest duration, and whether changing position, eating, or drinking alters it.
