About Hiccups

Overview
Hiccups, also known as singultus, are sudden and involuntary contractions of the diaphragm muscle. The diaphragm is a large muscle located beneath the lungs that helps with breathing. During a hiccup, the diaphragm contracts forcefully, causing a quick intake of breath. This contraction is followed by the closure of the vocal cords, resulting in the characteristic "hic" sound. Hiccups can occur for various reasons, such as eating too quickly, swallowing air, consuming carbonated beverages, or experiencing emotional stress. While hiccups are usually harmless and short-lived, lasting only a few minutes, in some cases they can persist for longer periods. Prolonged hiccups lasting more than 48 hours may require medical attention as they can be associated with underlying health conditions or complications.
Causes and Risk Factors

The root causes of hiccups are related to stimulation or irritation of components in the hiccup system. These causes can be classified into different categories, including central nervous system, psychiatric, metabolic, toxic and infectious, ear-nose-throat disease, thoracic, and abdominal factors. While hiccups are mainly thought to be related to the brainstem, cases have also been reported where damage to the upper part of the brain, known as the supratentorial cortex, caused hiccups.

Non-modifiable risk factors for hiccups cannot be changed or controlled. These include neurological disorders, masses and GERD (gastroesophageal reflux disease). Even heart attacks can be associated with hiccups.

Modifiable risk factors for hiccups can be influenced or changed. These include:

  • A stomach that’s too full from food, alcohol, or swallowed air
  • Sudden changes in temperature
  • Smoking cigarettes
  • Strong emotions like excitement or stress

Symptoms

Hiccups can have different effects. Some cases go away on their own, while others can last a long time, which might signal a health issue. Here are the common symptoms associated with hiccups:

Early symptoms:

  • Sudden, uncontrollable tightening of the diaphragm and the muscles between the ribs (intercostal muscles)
  • Rapid inhalation followed by a "hic" sound

Later stages/higher severity symptoms:

  • Irritability: Hiccups may cause irritability in babies, children, and adults.
  • Decreased appetite: Some individuals may experience a decreased desire to eat during hiccups.
  • Difficulty sleeping: Hiccups can disrupt sleep patterns and make it challenging to fall asleep or stay asleep.
  • Gastroesophageal reflux symptoms: Hiccups may be a symptom of gastroesophageal reflux, which is the flow of stomach contents into the esophagus, causing regurgitation.

It's important to note that if you or your baby have hiccups that won’t go away along with other symptoms like a stuffy nose or cough, it's best to consult with a healthcare professional for further evaluation and guidance. Hiccups aren’t usually a sign of a cold, but cold symptoms can sometimes trigger them.

Diagnosis

To diagnose hiccups, healthcare providers may perform the following examinations, tests, and procedures:

  • Physical exam: The healthcare provider will look for signs that might explain ongoing hiccups, such a stomach tenderness, breathing issues, or any swelling in the neck or throat area. They may also check for muscle weakness or trouble with body movements to see if an underlying health condition could be causing the hiccups.
  • Medical history: The healthcare provider will gather information about your medical history and any previous diagnoses.
  • Lab tests: Blood tests may be ordered to check for infections, heart problems, kidney disease, or diabetes. The specific tests ordered will depend on your symptoms and the diseases being considered.
  • Imaging studies: Imaging tests like X-rays, CT (computed tomography) scans, or MRI (magnetic resonance imaging) scans may be recommended to look for any unusual structures in the body that could be affecting the nerves or diaphragm.
  • Endoscopic test: In some cases, a healthcare professional may perform an endoscopic test by passing a flexible tube with a small camera down your throat to check the windpipe or esophagus.

Additional examinations, tests, and procedures may be recommended based on initial findings or individual factors. If necessary, your primary care provider may refer you to specialists who can provide more in-depth evaluations and treatments tailored to your condition.

Treatment Options

The goals of treatment for hiccups are to alleviate the symptoms and resolve the underlying cause. Here are the different treatment options and how they work to achieve these goals:

  • Medications:
  • Antispasmodic medications: These medications help stop smooth muscle tissue from twitching or cramping, which can help alleviate hiccups.
  • Medications used to treat GERD: Some medications used to treat gastroesophageal reflux disease (GERD) may also be prescribed for chronic hiccups.
  • Therapies:
  • Injections: In some cases, when medications are not effective enough, an injection of bupivacaine may be necessary to block the nerve that causes hiccups.
  • Therapeutic procedures:
  • Surgery: If medications and injections do not help, surgery may be considered. This involves inserting a device that uses electrical stimulation to stop the hiccups.
  • Self-care and health behavior changes:
  • Breathing into a paper bag
  • Drinking or sipping a glass of cold water
  • Holding your breath
  • Gargling with ice water
  • Other treatments:
  • Treating the underlying health condition causing the hiccups: If there is an underlying health condition contributing to the hiccups, treating that condition may help alleviate the symptoms.

It's important to note that each treatment option may be recommended based on the individual's specific situation and underlying cause of hiccups. It's always best to consult with a healthcare professional for personalized advice.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
