Hiccupping is a symptom. It may sometimes be accompanied by a slight tightening sensation in your chest, abdomen or throat.
When to see a doctor
Make an appointment to see your doctor if your hiccups last more than 48 hours or if they are so severe that they cause problems with eating, sleeping or breathing.
The most common triggers for hiccups that last less than 48 hours include:
- Drinking carbonated beverages
- Drinking too much alcohol
- Eating too much
- Excitement or emotional stress
- Sudden temperature changes
- Swallowing air with chewing gum or sucking on candy
Hiccups that last more than 48 hours may be caused by a variety of factors, which can be grouped into the following categories.
Nerve damage or irritation
A cause of long-term hiccups is damage to or irritation of the vagus nerves or phrenic nerves, which serve the diaphragm muscle. Factors that may cause damage or irritation to these nerves include:
- A hair or something else in your ear touching your eardrum
- A tumor, cyst or goiter in your neck
- Gastroesophageal reflux
- Sore throat or laryngitis
Central nervous system disorders
A tumor or infection in your central nervous system or damage to your central nervous system as a result of trauma can disrupt your body's normal control of the hiccup reflex. Examples include:
- Multiple sclerosis
- Traumatic brain injury
Metabolic disorders and drugs
Long-term hiccups can be triggered by:
- Electrolyte imbalance
- Kidney disease
Men are much more likely to develop long-term hiccups than are women. Other factors that may increase your risk of hiccups include:
- Mental or emotional issues. Anxiety, stress and excitement have been associated with some cases of short-term and long-term hiccups.
- Surgery. Some people develop hiccups after undergoing general anesthesia or after procedures that involve abdominal organs.
Prolonged hiccups may interfere with:
- Wound healing after surgery
