Causes of hiccups and treatment

Hiccups begin when the diaphragm contracts suddenly and the vocal cords close. Common triggers include eating a large meal, swallowing air, fizzy drinks, alcohol, spicy foods, emotional excitement, laughter, or abrupt temperature changes. Repeated episodes may accompany [Acid Reflux](/conditions/acid-reflux/) or [Gastritis](/conditions/gastritis/), particularly when there is burning, nausea, bloating, or upper-abdominal discomfort. Persistent hiccups can sometimes be linked to a medicine or an underlying illness, so the pattern and accompanying symptoms matter more than the sound or intensity alone.

For a brief episode, stop eating, sit upright, breathe slowly, and take small sips of water. Reduce swallowed air by eating slowly and avoiding straws, chewing gum, and carbonated drinks while symptoms are active. Treating a trigger can help: a clinician may recommend a plan for reflux or stomach inflammation and may review medicines that could be involved. [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) should be used only as directed, with extra care during pregnancy or when you take other medicines. Persistent hiccups may need prescription treatment after an examination identifies the likely cause.

Contact a clinician when hiccups persist, repeatedly return, disturb sleep, make eating difficult, or come with vomiting, trouble swallowing, ongoing heartburn, or abdominal pain. Seek urgent care for breathing difficulty, severe chest pain, confusion, new weakness, or a sudden severe headache. Do not try to stop severe hiccups with unsafe swallowing challenges or forceful manoeuvres.

Ask what is the most likely trigger in your case, whether reflux or stomach irritation needs treatment, and whether any medicine should be changed. Bring a list of medicines and note when episodes start, how long they last, and what relieves them.
