Hiccups persistent

Overview

Hiccups are sudden, involuntary contractions (tightenings) of the diaphragm muscle followed by a quick closing of the vocal cords, which makes the 'hic' sound. Persistent hiccups last longer than 48 hours and may be a sign of an underlying health condition.

Short hiccups are very common - almost everyone gets them. Persistent hiccups are less common, affecting about 1 in 1,000 people each year.

Persistent hiccups can affect anyone but are more common in men, older adults, and people with certain medical conditions such as acid reflux, stroke, or kidney disease.

Symptoms

Common symptoms

• Repeated 'hic' sounds every few seconds or minutes
• Involuntary twitching of the upper belly area
• Discomfort or fullness in the chest or throat

Symptoms in children

• Same 'hic' sound and belly movement as adults
• May be more distressing or cause crying
• Often stop on their own without treatment

Symptoms in older adults

• Hiccups may last longer and be harder to stop
• More likely to be caused by an underlying medical condition
• Can interfere with eating, sleeping, and daily activities

Causes

Main causes

• Irritation of the nerves that control the diaphragm (such as from acid reflux, a swollen stomach, or a hiatal hernia)
• Conditions affecting the brain or spinal cord (such as a stroke, tumour, or multiple sclerosis)
• Metabolic problems (such as kidney failure, electrolyte imbalances, or diabetes)
• Certain medicines (for example, steroids, some sedatives, or chemotherapy drugs)

Risk factors

• Drinking alcohol or carbonated beverages
• Eating spicy or very hot food
• Stress or strong emotions
• Smoking
• Having a condition that affects the stomach, esophagus, or nerves

When to see a doctor

See a doctor urgently if:

• Hiccups lasting more than 48 hours
• Hiccups so severe you cannot eat, drink, or sleep
• Hiccups with other worrying symptoms like chest pain, trouble breathing, or weakness

Book a routine appointment if:

• If hiccups happen often and bother you
• If you have a known medical condition and hiccups start suddenly
• To discuss any medications that might be causing them

Diagnosis

Your doctor will ask about your hiccups: when they started, how often they happen, and what makes them better or worse. They will also review your medical history and any medicines or supplements you take.

Tests that may be done

• A physical exam, including listening to your chest and belly
• Blood tests to check for infections, kidney or liver problems, or electrolyte imbalances
• Imaging tests such as a chest X-ray, CT scan, or MRI to look for causes in the chest or brain

What to expect at your appointment

Most people with persistent hiccups will have a careful evaluation to find the cause. This may take a few visits or tests. The doctor will explain each step and involve you in decisions about your care.

Treatment

Treatment first aims to fix the underlying cause. If no cause is found, or if hiccups are very bothersome, there are medicines and other therapies that can help reduce them.

Self-care at home

• Hold your breath for as long as is comfortable
• Drink a glass of cold water slowly or sip iced water
• Swallow a teaspoon of granulated sugar (dry)
• Breathe into a paper bag (not plastic) for a few breaths
• Pull your knees to your chest while leaning forward

Medical treatments

If simple steps do not help, your doctor may suggest a medicine that can calm the diaphragm or change nerve signals. These are usually taken as tablets for a short time. Other options include nerve blocks or injections for very stubborn cases. Treatment is always tailored to the individual.

When is surgery considered?

Surgery is rarely needed for hiccups. It might be considered if the hiccups are caused by a physical problem like a diaphragm pacemaker or nerve compression that can be fixed with an operation.

Living with this condition

Persistent hiccups can make eating, talking, and sleeping difficult. It helps to eat smaller meals, avoid very hot or cold food, and find ways to relax. Keep a diary of when hiccups happen to identify triggers.

Lifestyle tips

• Avoid carbonated drinks and alcohol
• Try stress-reducing activities like deep breathing, meditation, or gentle exercise
• Quit smoking if you smoke – ask your doctor for support

Diet and exercise

Eat smaller, more frequent meals. Avoid spicy, acidic, or very hot foods that can trigger hiccups. Gentle exercise such as walking may help reduce stress and improve digestion.

Mental health and emotional wellbeing

Having persistent hiccups can be frustrating, embarrassing, and tiring. It is normal to feel anxious or stressed about it. If hiccups interfere with your mood or daily life, talk to your doctor. You are not alone.

Prevention

Not all hiccups can be prevented, but you may be able to reduce how often they happen by avoiding common triggers like alcohol, carbonated drinks, spicy foods, and eating too quickly.

Complications

If left untreated

• Difficulty eating and drinking, leading to weight loss or dehydration
• Exhaustion from lack of sleep
• Strain on relationships or work due to embarrassment
• The underlying cause (if serious) may not be found and treated

Long-term outlook

Most cases of persistent hiccups get better once the cause is treated. Even when no cause is found, treatments are often effective at stopping or reducing hiccups. The outlook is generally very good, and serious complications are rare.
