Hypnosis

Overview

Hypnosis is a natural state of deep focus and relaxed attention. When you are in this state, your mind is more open to suggestion, and a trained practitioner can guide your thoughts and feelings in a helpful direction. Despite what you may have seen on stage shows, hypnosis is not sleep and it is not mind control. You stay awake, you can hear what is going on, and you can stop at any time. When hypnosis is used as a treatment, it is often called hypnotherapy. A session usually starts with a calm conversation, then the practitioner helps you settle into a relaxed, focused state, and then offers gentle suggestions — for example, about feeling calmer, coping with pain, or changing a habit. You are always the one in charge.

Hypnosis has been used in medicine for well over a century, and it is used in many countries today. There is no reliable count of how many people try it, but it is widely available privately, and some NHS services — for example, gut-focused hypnotherapy for IBS — offer it as part of care. Most people find it a pleasant, relaxing experience.

Symptoms

Common symptoms

• A feeling of deep calm and physical relaxation, sometimes with heavy or floaty limbs
• Narrowed attention — everyday worries or background noise may fade into the background
• Losing track of time, or feeling that time has passed more quickly or slowly than usual
• Vivid daydream-like images or colours behind closed eyes
• A sense that suggestions feel easy to accept, while still knowing you could resist them
• Awareness of the practitioner's voice and your surroundings throughout
• Afterwards, feeling rested, sleepy, or pleasantly 'spaced out' for a short while

Symptoms in children

• Children often enter a hypnotic state very easily through imagination and play, and may not need a formal 'induction'
• They may describe it as daydreaming, pretending, or 'being in a story'
• It is often used to help with needle fear, dental visits, tummy pain, anxiety and habit problems such as bedwetting
• A parent or carer is usually welcome to stay in the room
• Look for signs of distress; children should never feel pushed or pressured to continue

Symptoms in older adults

• Hypnosis may be used for long-term pain, sleep problems, anxiety or coping with tests and procedures
• Memory or hearing difficulties may mean the practitioner needs to slow down, speak clearly and repeat suggestions
• It is worth reviewing your medical conditions and any medicines with your doctor first, so everyone is clear about what hypnosis is and is not for
• Sessions can be made shorter and more gentle if needed

Causes

Main causes

• Hypnosis is a technique, not an illness, so it does not have causes. People usually seek hypnotherapy for a problem rather than for hypnosis itself.
• Common reasons include long-term pain, anxiety and stress, irritable bowel syndrome (IBS), trouble sleeping, fear of medical or dental procedures, childbirth preparation, and wanting to stop smoking.
• Some people try it because other treatments have not helped enough, or because they prefer a non-medicine approach alongside their usual care.

Risk factors

• A history of psychosis or other conditions where contact with reality can become shaky — talk to your doctor first
• Severe dissociative symptoms (feeling disconnected from yourself or your surroundings)
• Being under the influence of alcohol or drugs during a session
• A history of trauma or abuse — it is important to tell the practitioner so sessions can be handled sensitively
• Epilepsy or a history of seizures — check with your doctor first
• Choosing an untrained or unregulated practitioner

When to see a doctor

See a doctor urgently if:

• You have a new physical symptom such as chest pain, severe headache, sudden weakness or breathlessness — get medical help first, before considering hypnosis
• You feel unsafe, very distressed or unable to cope after a session
• You have been using hypnosis to manage a serious condition and your usual medical care has slipped

Book a routine appointment if:

• You are thinking about hypnotherapy and have an ongoing health condition, so you can talk through whether it is suitable
• You have persistent pain, anxiety, low mood, sleep problems or gut symptoms that have not been properly checked
• You want to know whether hypnotherapy is available through your local health service
• You are unsure whether a practitioner is properly trained and registered

Diagnosis

There is no test or diagnosis for hypnosis — it is something you do, not something you have. If you see a clinical hypnotherapist, they will usually start with a conversation about what you want help with, your health history and your medicines. Your GP may first check for other causes of your symptoms — for example, blood tests or a review of your gut symptoms — so that treatable conditions are not missed. The practitioner should explain what will happen, answer your questions, and get your clear consent before starting.

Tests that may be done

• No medical tests are needed to 'measure' hypnosis
• Your GP may arrange routine tests to look into symptoms such as pain, tiredness or bowel problems before suggesting hypnotherapy
• You may be asked to fill in a short questionnaire about your mood, anxiety or symptom severity, so progress can be tracked

What to expect at your appointment

A session usually lasts around 30 to 60 minutes. You will sit or lie comfortably while the practitioner speaks in a calm, steady voice, guiding your attention — often with breathing, imagery and muscle relaxation. You stay awake and aware. Afterwards you may feel sleepy for a few minutes and can sit quietly with a drink before you leave. Courses typically run for several weekly sessions, and you should feel free to ask questions or stop at any point.

Treatment

Hypnosis is used as a form of focused talking therapy. A typical course involves several sessions with a trained practitioner, often weekly, with the aim of teaching your mind and body to respond differently — for example, to feel calmer, to turn down the volume on pain, or to break a habit. It is usually used alongside, not instead of, standard medical care. Self-hypnosis, which you practise on your own, is often taught so you can keep using the skills after the sessions end.

Self-care at home

• Ask your GP or pharmacist about reputable local practitioners, or look for a professional body that keeps a register of trained hypnotherapists
• Practise the relaxation or self-hypnosis exercises you are taught — little and often works better than one long session
• Choose a quiet, comfortable time and place for practice, and avoid doing it while driving or doing anything that needs your full attention
• Keep a simple diary of your symptoms, sleep and mood so you can see whether it is helping
• Tell your practitioner about all your health conditions, medicines and past experiences that might matter
• Keep up your usual medical appointments and treatments

Medical treatments

Hypnotherapy is usually delivered as a structured course of sessions, either privately or through some health services. It may be combined with other approaches — for example, gut-focused hypnotherapy alongside dietary advice for irritable bowel syndrome, or relaxation and hypnosis as part of a pain management programme. Some psychological therapy services offer hypnosis-based relaxation as one part of a wider talking therapy plan. Your doctor can discuss whether it fits with your other care; hypnosis should never be used to replace necessary investigations or treatment.

When is surgery considered?

Hypnosis is not a surgery, and it never replaces an operation or anaesthesia. It is sometimes used alongside standard care — for example, to help people feel calmer before an operation, or as part of pain relief afterwards. If you are offered it around the time of surgery, it will be as an add-on to your usual anaesthetic and surgical team's plan, not instead of it.

Living with this condition

If hypnotherapy helps you, the aim is usually to build a short daily or near-daily practice of self-hypnosis or relaxation — often just 10 to 20 minutes. Many people use it at the same time each day, such as before bed or after breakfast. Progress can be gradual, so it helps to think in weeks rather than days, and to keep doing the other things that support your health.

Lifestyle tips

• Build a calm wind-down routine in the evening to support sleep
• Be realistic about what hypnosis can do — it works best alongside other healthy habits, not as a quick fix
• Avoid relying on hypnosis alone for symptoms that need medical checks
• Try gentle movement such as walking, stretching or yoga to ease tension
• Keep alcohol low, as it can interfere with sleep, mood and relaxation practice

Diet and exercise

There is no special diet for hypnosis. If you are using it for gut symptoms such as IBS, your doctor or dietitian may suggest dietary changes alongside it — for example, adjusting fibre or trying a guided elimination approach with professional support. Regular gentle activity, such as a daily walk, can help with mood, sleep and pain, and it pairs well with relaxation practice. Avoid big lifestyle overhauls all at once; small, steady changes tend to last.

Mental health and emotional wellbeing

Hypnosis can help some people feel calmer and more in control, and it is sometimes used for anxiety and low mood as part of a wider plan. It can also stir up strong feelings or memories, so a trained practitioner will check in with you and go at your pace. Hypnosis is not a substitute for proper mental health care. If you are struggling with your mental health, please reach out — talk to your doctor, and if you are in crisis or having thoughts of harming yourself, contact your local crisis service or your local emergency number straight away, or ask someone to stay with you while you get help.

Prevention

Hypnosis is not a disease, so there is nothing to prevent. What you can do is use it safely: choose a trained, registered practitioner, be honest about your health history, keep up your usual medical care, and treat hypnosis as one part of a wider plan rather than a replacement for diagnosis and treatment.

Complications

If left untreated

• Hypnosis itself does not need to be 'treated'. The main risk is delay — using hypnosis instead of getting a symptom checked could mean a treatable condition is missed.
• Rarely, sessions can stir up upsetting memories or emotions, or leave someone feeling unsettled for a while.
• Some people report vivid or confusing memories arising during or after sessions; memories recalled under hypnosis are not always reliable, so they should not be treated as proof of what happened.
• Private hypnotherapy costs money and time, and unregulated practitioners may make unrealistic claims.
• Feeling disappointed if it does not help — this does not mean you failed, only that it was not the right approach for you.

Long-term outlook

For many people, hypnosis is a safe, pleasant and genuinely useful tool — particularly for irritable bowel syndrome and for pain, where the research is strongest. Others find it makes little difference, and that is common too. It works best alongside good medical care, a supportive practitioner and a bit of regular practice. There is every reason to be hopeful about finding a combination of approaches that helps you, and your doctor can help you review what is working.
