Hiccups
Overview of Hiccups
Most people have experienced hiccups at some point in their lives.
Hiccups are involuntary, repetitive contractions of the diaphragm (the muscle separating the chest from the abdomen) followed by a sudden closure of the vocal cords. This results in a brief interruption of airflow, producing the characteristic “hic” sound.
Common triggers for hiccups include eating or drinking too quickly, consuming very hot or cold foods, spicy dishes, alcohol, and carbonated drinks. Babies may also develop hiccups after feeding, crying, or coughing. However, at times, the cause of hiccups cannot be identified.
In most cases, hiccups are harmless and resolve on their own within a few minutes. Techniques like holding your breath, drinking water, or eating sugar are commonly used to stop hiccups.
However, if hiccups persist for days or even weeks, it may indicate an underlying health condition. In such cases, it is important to identify the cause and address it appropriately.

Symptoms Of Hiccups
The primary symptom of hiccups is a slight tightening sensation in the chest, abdomen, or throat, followed by the characteristic hiccup sound.
The hiccup reflex involves the coordinated action of:
- Diaphragm: A large muscle beneath the lungs that helps with breathing by contracting rhythmically.
- Windpipe muscles: These muscles control the opening and closing of the windpipe.
- Nerves: These nerves act upon the diaphragm.
If any of the nerves in this system are triggered, the diaphragm contracts involuntarily, drawing air into the lungs. This causes the epiglottis (the top of the windpipe) to close, producing the distinct “hic” sound.
Triggering Factors Of Hiccups
I. Common Causes of Acute Hiccups:
- Eating too quickly or overeating
- Consuming very hot or cold foods
- Eating spicy food
- Drinking alcohol or carbonated beverages
- Swallowing air (e.g., chewing gum or sucking on candy)
- Indigestion
- Exposure to strong odors
- Inhaling toxic fumes
- Smoking
- Overstretching the neck
- Sudden temperature changes
- Nervousness or excitement
II. Causes of Persistent and Intractable Hiccups:
Nerve Damage or Irritation:
Conditions like Gastroesophageal Reflux Disease (GERD), sore throat, goiter, or tumors may irritate the nerves controlling the diaphragm.
Medications:
Certain drugs can trigger hiccups, such as:
- Antibiotics (e.g., azithromycin)
- Psychiatric medications (e.g., aripiprazole)
- Anesthetic drugs (e.g., propofol)
- Steroids
- Some epilepsy medications
Instrumentation:
Medical procedures involving instruments, such as abdominal or chest surgeries, can irritate the diaphragm’s controlling nerves, leading to hiccups.
Other Medical Conditions:
Several conditions may cause persistent or frequent hiccups, including:
- Oesophagitis (inflammation of the food pipe)
- Overactive thyroid
- Pleurisy (inflammation around the lungs)
- Pneumonia
- Tuberculosis
- Influenza
- Pericarditis (inflammation around the heart)
- Diabetes
- Malaria
- Hernia
- Uremia (high waste levels in the blood)
- Hypocalcemia (calcium deficiency)
- Chronic kidney failure
- Multiple sclerosis
- Stroke
- Cancer
III. Causes of Hiccups in Infants:
Hiccups are quite common in babies under 12 months. Infants may experience hiccups more frequently during or after feeding due to swallowing food too quickly or overfeeding. This can cause the stomach to expand, which presses against the diaphragm and triggers hiccups.
Hiccups can also indicate that the baby is full. Pediatricians often recommend shorter feeds with breaks for burping. Typically, a baby's hiccups will stop within 5 to 10 minutes. However, if they persist for more than a couple of hours, it is advisable to consult a doctor.
Note: Generally, hiccups in infants are a sign of normal growth and development.
Types Of Hiccups
Hiccups can be classified based on their duration:
- Acute Hiccups: Last less than 48 hours.
- Persistent Hiccups: Last more than two days.
- Intractable Hiccups: Persist for over a month.
Potential Risks for Hiccups
- Men are more likely than women to experience long-term hiccups.
- Anxiety, stress, and strong emotional reactions.
- People who have undergone general anesthesia.
- Post-operative patients, particularly those who have had abdominal or chest surgery.
- Pregnancy.
Diagnosis Of Hiccups
Although no specific test is required for hiccups, in cases of persistent or long-lasting hiccups, it is crucial to identify any underlying medical conditions.
History
The doctor will inquire about the duration of your hiccups, any treatments you have tried, and whether they are linked to recent events or procedures. They may also ask for details about your medical background, including any gastrointestinal or neurological disorders, and your drug history, which may include alcohol use.
Physical Examination
During the exam, the physician may perform a neurological check to assess:
- Balance and coordination
- Muscle strength and tone
- Reflexes
- Vision and sense of touch
Laboratory Tests
While no tests are needed for short-term hiccups, the following blood tests may be suggested for persistent ones:
- Serum electrolytes
- Calcium levels
- Blood urea nitrogen (BUN) levels
- Creatinine levels
- Lipase levels
- Liver function tests
Imaging Techniques
These tests can help identify potential issues within the chest, neurological changes, or lesions that may be causing hiccups:
- ECG (Electrocardiogram)
- Chest X-ray
- CT scan (Computerized Tomography)
- MRI (Magnetic Resonance Imaging)
Specialists to Consult
Most hiccups resolve on their own, but if they persist for more than two days, it could indicate an underlying issue. The following specialists can help in diagnosing and treating persistent hiccups:
- General physicians
- Otolaryngologists (specializing in head and neck conditions)
- Gastroenterologists (specializing in digestive disorders)
- Neurologists (specializing in brain, spinal cord, and nerve issues)
- Pulmonologists (specializing in lung conditions)
When to Seek Medical Help
Seek medical attention if your hiccups persist for more than 48 hours, recur frequently, or are disrupting your daily life. Also, consult a doctor immediately if you experience any of the following symptoms along with hiccups:
- Headaches
- Balance problems
- Numbness throughout the body
Preventive Measures Of Hiccups
Although hiccups are common and usually resolve without intervention, you can make some lifestyle changes to minimize their occurrence:
Do's:
- Eat smaller meals
- Take cold showers
- Manage stress and anxiety
- Protect yourself from sudden temperature changes
Don'ts:
- Eat too quickly
- Consume spicy foods
- Drink alcoholic, carbonated, or fizzy beverages
- Eat or drink something very cold right after something hot
- Chew gum
- Smoke
- Stretch your neck excessively
- Inhale harmful fumes
Treatment Of Hiccups
Your doctor will first determine if the hiccups are caused by a medical condition or medication. If so, treating the underlying issue or switching medications should stop the hiccups. The specific treatment will depend on the cause and may include:
I. Medications for Specific Causes:
- For nasal symptoms: Nebulized 0.9% saline (2 ml over 5 minutes).
- For gastric irritation: Proton pump inhibitors like omeprazole, pantoprazole, or lansoprazole.
- For gastric distension: Medications like metoclopramide, domperidone, and itopride.
- For excessive intestinal gas: Antiflatulents like simethicone, peppermint water, or carminative agents.
II. Medications for Persistent Hiccups:
- Dopamine Antagonists: These drugs help relax the diaphragm muscle and include haloperidol, olanzapine, chlorpromazine, and methylphenidate.
- GABA Agonists: Baclofen is a common treatment as it relaxes muscles. Caution is advised for older patients and those with kidney issues.
- Local Anesthetics: Low-dose lignocaine infusion or nebulization can help stop hiccups.
- Antiepileptics: These help relax the diaphragm’s nerve supply, with gabapentin and sodium valproate being commonly used.
- Calcium Channel Blockers: Nifedipine can help manage hiccups.
III. Invasive Procedures: In extreme cases, when other treatments fail, the following invasive methods may be considered:
- Nasogastric Intubation: A tube is inserted into the stomach via the nose.
- Phrenic Nerve Block: An anesthetic is used to block the nerve that controls the diaphragm.
- Diaphragmatic Pacemaker: A surgically implanted device that stimulates the nerves controlling the diaphragm.
Health Complications Of Hiccups
Frequent bouts of acute hiccups or persistent, long-lasting hiccups can severely affect one's quality of life, causing physical discomfort, embarrassment, and emotional distress. The following complications are commonly associated with these conditions:
- Dehydration
- Malnutrition
- Fatigue
- Insomnia
- Weight loss
- Anxiety and depression
- Slower healing of scars from abdominal surgery, increasing the risk of wound complications.
Strong, persistent hiccups may also lead to:
- A decrease in heart rate
- A drop in blood pressure
- Pneumothorax (lung collapse) due to air or gas accumulation between the lungs and chest wall.
Alternative Therapies For Hiccups
Acupuncture
Acupuncture may serve as an alternative treatment for persistent and intractable hiccups. It works by stimulating the nerves responsible for hiccup reflexes. Some case studies suggest that acupuncture can be effective in managing chronic hiccups, even when conventional treatments fail. While more research is needed on its safety and efficacy, there have been instances where people have successfully stopped long-term hiccups using this method.
Massage
A carotid sinus massage may be recommended for chronic hiccups. This technique involves gently rubbing the carotid artery in the neck by a trained healthcare provider.
Homemade Remedies for Hiccups
Though hiccups usually go away on their own, here are some remedies that may help if they persist. These methods are commonly suggested based on anecdotal evidence and aim to stimulate the vagus or phrenic nerves, which are involved in diaphragm function.
1. Posture and Breathing Techniques:
- Pull your knees toward your chest and lean forward.
- Hold your breath for several seconds or longer.
- Breathe out against a closed mouth and nose.
- Breathe into a paper bag (do not cover your head).
2. Pressure Point Techniques:
- Pull your tongue gently.
- Apply pressure to your diaphragm.
- Pinch your nose closed while drinking water.
- Use your thumb to apply pressure to the palm of your other hand.
- Massage your carotid artery gently on both sides of your neck.
3. Dietary Tips:
- Swallow a teaspoon of sugar.
- Drink a glass of warm water slowly, without stopping to breathe.
- Sip ice-cold water or gargle with ice water.
- Bite on a lemon or taste vinegar.
4. Other Tips:
- Distract yourself with an engaging activity.
- Tap or rub the back of your neck.
Home Care Tips for Infant Hiccups:
Feeding Tips:
- Encourage burping during or after feedings.
- Keep the baby upright for 20-30 minutes after feeding.
- If the baby is bottle-fed, use a tilted bottle to reduce air swallowing.
Other General Tips:
- Offer cold water or herbal teas like fennel, chamomile, or peppermint (using a dropper).
- Gently rub the baby’s back.
- Apply light pressure on the baby’s upper stomach.
- Tickle to distract the baby from the hiccups.
It’s important to consult your child’s pediatrician before trying these methods.
What Not to Do:
- Do not startle or scare the baby.
- Never attempt to hold the baby's breath.
Lifestyle Modifications Hiccups
While most hiccups are harmless and resolve on their own, chronic or prolonged episodes can be very distressing and disruptive. They can interfere with daily activities, including sleep, and if they persist, can lead to exhaustion due to lack of rest. Over time, this can severely impact an individual's quality of life.
To manage the condition, it's essential to rest well, eat and drink in small portions throughout the day, and be mindful of potential complications. Regularly taking prescribed medications and keeping yourself engaged in activities to distract from the discomfort can help. Finding hobbies and joining support groups with others experiencing similar issues may also provide relief.
Staying in touch with your healthcare provider during treatment is important to prevent the recurrence of hiccups and mitigate the risks associated with chronic episodes.
