What You'll Learn
Hiccups can disrupt sleep onset but not established sleep
Hiccups can be a nuisance and, in some cases, a cause for concern. While hiccup usually go away on their own, they can sometimes last for prolonged periods, disrupting daily life and sleep patterns.
Hiccups are caused by the involuntary contraction of the diaphragm, the muscle between the chest and stomach that regulates breathing. When the diaphragm contracts out of rhythm, it causes the vocal cords and voice box to close suddenly, resulting in a rush of air into the lungs and the characteristic "hic" sound.
While hiccups typically do not require medical attention, they can sometimes indicate an underlying medical condition, especially if they persist while sleeping. In rare cases, prolonged hiccups can lead to sleep problems, weight loss, and even more severe complications such as heart arrhythmias or gastro-oesophageal reflux disease (GORD). Therefore, it is recommended to consult a doctor if hiccups last for more than 48 hours or interfere with eating, drinking, or sleeping.
Research has been conducted to explore the effect of sleep on hiccups and vice versa. One study found that the incidence of new bouts of hiccups and the likelihood of hiccups being present were highest during wakefulness and decreased through the stages of slow-wave sleep (SWS) to rapid eye movement sleep (REMS). There was a notable tendency for hiccups to disappear at sleep onset and REMS onset. The frequency of hiccups within a bout also slowed as individuals progressed through the sleep stages.
In conclusion, while hiccups can disrupt sleep onset, they do not appear to interfere with established sleep. The neural mechanisms responsible for hiccups are strongly influenced by the sleep state. Therefore, while hiccups may prolong the time it takes to fall asleep, they are less likely to cause arousals or awakenings once sleep is established.

Hiccups are often caused by irritation to the diaphragm muscle
Hiccups are usually harmless and often go away without any treatment. They occur when the diaphragm, a muscle between the chest and stomach, contracts suddenly. This muscle plays a role in controlling breathing. When you breathe in, the diaphragm contracts and moves downwards, and the vocal cords at the top of the throat close to control the intake of air. When you breathe out, the diaphragm relaxes and air passes out of the lungs.
Hiccups are caused by irritation to the nerves that control the diaphragm, including the vagus nerve and the phrenic nerve. These nerves make up a pathway called the reflex arc, which manages the body's involuntary functions, such as breathing, digestion, and heart rate. Irritation of these nerves can cause the diaphragm to contract involuntarily, resulting in a spasm and the characteristic "hic" sound produced by the closing of the vocal cords.
Several factors can irritate the diaphragm and trigger hiccups. This includes eating or drinking too quickly, consuming large meals, drinking carbonated or alcoholic beverages, or experiencing anxiety, excitement, or stress. In some cases, certain health conditions, surgeries, or medications can also irritate the diaphragm and lead to hiccups.
If hiccups persist for an extended period, such as longer than two days, it is recommended to consult a healthcare provider. Persistent hiccups can interfere with essential functions such as eating, drinking, and sleeping, potentially leading to unintentional weight loss or sleep disturbances. In rare cases, severe and prolonged hiccups can result in heart arrhythmias or gastro-oesophageal reflux disease (GORD). Therefore, seeking medical advice is crucial to identify and address any underlying causes.

Hiccups can be a symptom of gastro-oesophageal reflux disease (GORD)
Hiccups are usually harmless and short-lived, but persistent hiccups can be a symptom of an underlying medical condition such as gastro-oesophageal reflux disease (GORD). GORD, also known as GERD, is a chronic acid reflux condition that affects the oesophagus. It occurs when the mechanisms that typically keep acid out of the oesophagus do not function correctly, resulting in the backflow of acid, food, or liquid from the stomach into the throat.
GORD can be challenging to diagnose, and it is essential to rule out other potential causes of persistent hiccups. In some cases, hiccups may be associated with reflux disease, as evidenced by a case study of a 23-year-old female who presented with protracted hiccups. Endoscopy and conventional pH-metry confirmed a diagnosis of non-erosive reflux disease as the underlying cause.
The association between GORD and hiccups is not always clear-cut. In one case, a 62-year-old man with severe heartburn and persistent hiccups underwent various diagnostic tests and treatments. While the Nissen fundoplication procedure improved his heartburn, it did not resolve his hiccups. This suggests that the presence of GORD and hiccups may not always have a direct cause-and-effect relationship.
However, it is important to seek medical advice if hiccups persist for an extended period, as they may indicate an underlying condition such as GORD. A gastroenterologist may evaluate the oesophagus using tests such as an esophagram (a type of X-ray exam) or an upper endoscopy, which involves inserting a tiny camera into the throat to examine the oesophagus directly. Treatment options for GORD may include medication or addressing the underlying problem causing the hiccups.
While hiccups themselves are usually harmless, persistent hiccups can be a symptom of GORD, a more serious condition that requires medical attention. Therefore, it is always advisable to consult a healthcare professional if hiccups persist or interfere with daily activities such as eating, drinking, or sleeping.

Hiccups can be caused by stress, excitement or anxiety
Hiccups are caused by the diaphragm involuntarily contracting. The diaphragm is a muscle that separates the chest and belly and regulates breathing. When the diaphragm contracts, the lungs take in oxygen, and when it relaxes, the lungs release carbon dioxide. Hiccups occur when the diaphragm contracts out of rhythm, causing the larynx (voice box) and vocal cords to close suddenly. This results in a sudden rush of air into the lungs, creating the characteristic sound of hiccups.
While the causes of hiccups vary and there is no definitive list of triggers, emotional stress, excitement, or anxiety can be contributing factors. Hiccups stemming from these emotional triggers usually don't last long, ranging from a few minutes to a few hours at most. In rare cases, persistent hiccups may be a sign of an underlying medical condition.
Stress, excitement, or anxiety can irritate the phrenic nerve, which relays information from the brain to the diaphragm to control breathing. This irritation causes the diaphragm to spasm, resulting in hiccups. Additionally, heightened anxiety can lead to increased alcohol consumption, which can irritate the diaphragm and trigger hiccups.
If you experience hiccups for two full days without relief, it is recommended to seek medical attention. A doctor can determine the severity of the hiccups in relation to your overall health and identify any underlying conditions that may be causing them. In most cases, hiccups should go away on their own or with simple interventions within a few minutes.

Hiccups can be treated by breathing into a paper bag
Hiccups are usually harmless and go away on their own. However, if hiccups are persistent and disrupting your sleep, eating, or drinking, it is advised to see a doctor.
To perform this technique, slowly inhale and exhale into the paper bag to make it inflate and deflate. Stop if you feel lightheaded. It is important to note that this method should not be done with a plastic bag, as it is not porous and can lead to breathing in too much carbon dioxide.
In addition to the paper bag method, there are other breathing techniques that can help stop hiccups. One technique involves inhaling slowly and silently counting to five, then exhaling for a count of five. This slow breathing pattern can be repeated several times. Another technique is to simply hold your breath. Inhale until your lungs are full, hold your breath for 10-20 seconds, and then exhale slowly.
While hiccups usually do not require medical attention, persistent hiccups can be a sign of an underlying medical condition. If your hiccups are impacting your daily life, it is important to consult a doctor for proper diagnosis and treatment.

Frequently asked questions
Hiccups rarely cause complications as they usually go away on their own. However, if you have severe or persistent hiccups that disturb your ability to eat, drink or sleep, you may unintentionally lose weight or develop sleep problems. In rare but severe cases of hiccups, heart arrhythmias or gastro-oesophageal reflux disease (GORD) may occur.
Try breathing into a paper bag or holding your breath for a few seconds. Both of these actions cause carbon dioxide to build up in the lungs, which might encourage the diaphragm to relax.
Hiccups happen when your diaphragm, a muscle between your chest and stomach, suddenly contracts. Anyone can get hiccups, even a foetus growing in the womb. However, men are much more likely than women to get long-term hiccups. You might get hiccups if you have recently eaten a large or spicy meal, eaten too quickly, drunk a fizzy or alcoholic drink, or if you are feeling anxious, excited or stressed.
Hiccups disrupt sleep onset but not established sleep. Sleep efficiency is poor because of long waking periods, and there are deficiencies of both slow-wave sleep and rapid eye movement sleep.
See your GP if your hiccups last for more than 48 hours, keep coming back, or are making it harder to eat, drink or sleep normally.
