Summary Summary

Chronic hiccups are unintentional movements (spasms) of the diaphragm followed by rapid closure of the vocal cords that persist for an extended period of time. Hiccups often develop for no apparent reason and typically go away on their own after a couple minutes. However, chronic hiccups last over two days and in rare cases, may continue for over a month. Hiccups that recur over long periods of time are also considered "chronic." Depending on how long the hiccups last, affected people may become exhausted, dehydrated and/or lose weight due to interruptions in sleep and normal eating patterns. Other complications may include irregular heart beat and gastroesophageal reflux.^[1] The exact underlying cause is often unknown; some cases may be caused by surgery, certain medications and/or a variety of health problems such as central nervous system (brain and spinal cord) abnormalities, psychological problems, conditions that irritate the diaphragm, and metabolic diseases. Treatment of chronic hiccups varies but may include medications and/or surgery.^[2]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

Although the exact underlying cause of chronic hiccups is often unknown, many factors can contribute to the development of hiccups. For example, common triggers for hiccups include hot or spicy foods and liquids; harmful fumes; surgery; and/or certain medications.^[3] Chronic hiccups can also be associated with a variety of health problems including:^[1]^[2]

Pneumonia, pleurisy and other conditions that irritate the diaphragm
Brain abnormalities (i.e. strokes, tumors, injuries, infections)
Metabolic disorders
Gastrointestinal (esophagus, stomach, small/large intestines) diseases
Psychological problems such as hysteria, shock, fear, and personality disorders
Liver abnormalities
Kidney disorders

Inheritance Inheritance

Chronic hiccups are not thought to be inherited. Most cases occur sporadically in people with no family history of the condition.^[2]

Diagnosis Diagnosis

A diagnosis of chronic hiccups is usually obvious based on symptoms. However, a complete physical exam with various laboratory tests and imaging studies (i.e. chest X-ray, CT scan, MRI scan, and/or fluoroscopy of the diaphragm) may be performed to determine the underlying cause.^[1]^[2]

Treatment Treatment

Treatment for chronic hiccups often varies based on the underlying cause. In many cases, medications can be prescribed to treat chronic hiccups. These may include:^[1]^[2]

Tranquilizers such as chlorpromazine and haloperidol
Muscle relaxants
Anticonvulsant agents including phenytoin, valproic acid, and carbamazepine
Sedatives
Pain medications
Stimulants

Rarely, medications may not be effective in the treatment of chronic hiccups. In these cases, surgery to temporarily or permanently block the phrenic nerve may be performed. The phrenic nerve controls the diaphragm.^[2]

Prognosis Prognosis

The long-term outlook (prognosis) for people with chronic hiccups depends on the cause. Chronic hiccups are often associated with underlying medical conditions that vary in severity.^[2]

Depending on how long the hiccups last, affected people may experience the following complications regardless of the underlying cause:^[1]^[2]

Irregular heartbeat
Gastroesophageal reflux
Exhaustion
Dehydration
