What should you know about continuous hiccups?

A hiccup is an involuntary spasm of the diaphragm followed by sudden closure of the voice box. Eating quickly, swallowing air, fizzy drinks, alcohol, sudden temperature changes, and emotional excitement can trigger short episodes. Ongoing hiccups may reflect irritation from acid reflux or gastritis. Less commonly, medicines or problems affecting the chest, abdomen, metabolism, or nervous system may be involved. The duration and associated symptoms help a clinician decide how widely to investigate.

Take small sips of water, eat slowly, and avoid fizzy drinks, alcohol, large meals, and foods that clearly trigger symptoms. Sit upright after eating and keep a note of the start time, frequency, sleep disruption, and any reflux, pain, or vomiting. Do not try frightening or forceful remedies. If the episode continues or interferes with drinking, eating, or sleeping, arrange a medical review; treatment depends on the cause and may include prescribed medicine.

Seek urgent help if hiccups occur with severe chest or abdominal pain, difficulty breathing, repeated vomiting, inability to swallow fluids, confusion, weakness, trouble speaking, or a sudden severe headache. Prompt assessment is also needed when ongoing spasms prevent hydration, nutrition, or sleep.

Ask whether reflux or gastritis could be irritating the diaphragm, whether a medicine may be contributing, and what examination or tests are appropriate. Explain what you have eaten, any recent illness, and how the hiccups affect sleep and swallowing.
