What a health coach is, and why people with chronic illness and pain need one

The doctor has eighteen minutes. Your illness has the rest of the year.

The visit is over in eighteen minutes. You walk out with a name for what you have, a prescription, and a follow-up in three months. In the car, half of what was said is already gone. At home, the illness is still there, and so is everything around it: the nights you don't sleep, the job, the food, the people, the worry. Nobody is in the room for any of that.

That is the room a health coach works in. A health coach is not a diet plan. Food is part of my work, but it is one piece of the picture, not the whole job. Not a hoax, not a doctor, not a scam. Those are the four things people tell me they thought before we met, and I understand all four. Researchers who asked fifty adults what the word "coach" meant to them found a fifth: it sounded like sports, not like someone professional. They wanted an expert who also understood their life as a whole. That is the whole job. So let me tell you what a health coach is, what one does, and what the research says.

The health care system is not one person who does everything

Doctors diagnose and prescribe. Nobody in the system is paid to help you live with the diagnosis. A doctor is trained to find the disease and treat it. In most visits that means: name it, prescribe for it, next patient. Not because doctors are bad, but because they see hundreds of patients, and that is how they were trained. The same goes for the dietitian with food, and the therapist with mental health. Everyone works inside their own specialization, and nobody can do another's job. You would not ask a physical therapist to be your personal trainer.

A group of doctors at the University of California, San Francisco, put it better than I can. Doctors, they wrote, are "well-trained to 'give patients a fish', curing an acute problem or prescribing medications for a chronic condition." Health coaching "teaches patients and families 'how to fish'."

The founder of the Functional Medicine Coaching Academy, Dr Sandra Scheinbaum, said the same thing from the other side: "doctors often don't have the time to guide patients in how to implement these changes, a process typically consisting of finding motivation, setting realistic goals, and planning for overcoming obstacles. That's where health coaches come in."

What the research says

Your diagnosis is written in eighteen minutes. Your illness is lived in the other five thousand hours. Your doctor's visit lasts about eighteen minutes. That is the measured average in the United States; in Britain it is nine. Doctors writing in the New England Journal of Medicine put it this way: even people with chronic illness spend only a few hours a year with a doctor or nurse, and about 5,000 hours a year, awake, with everything else. Half of what the doctor says is forgotten by the time you reach the car. Half of the plan is never followed. Not because people don't want to, but because nobody is there to help or show them.

Dr Mark Hyman, who built the Center for Functional Medicine at Cleveland Clinic with health coaches on every care team, said it in one line: "80% of health happens outside the doctor's office."

The numbers behind the graph are not opinions. In a trial of 299 people with diabetes, those with a coach brought their blood sugar down three times as far as those without, in six months. In a trial of 441 people, those with a coach reached their health goals 46% of the time against 34% without. In the largest chronic pain trial of its kind, published in JAMA in 2026, 764 veterans were given either a care team with a health coach, group therapy, or usual care; after a year, the team with the coach had the biggest drop in pain interfering with daily life. And in a 2026 trial of people with Long COVID, after twelve weekly coaching sessions, the number of people who still had chronic fatigue at the end fell from 76% to 4%; with usual care it was still 60%.

Across all chronic illness, a Mayo Clinic team pooled thirty randomised trials in 2023 and concluded: "HWC improves QoL, SE, and depression across chronic illness populations." In plain words: quality of life, confidence to manage the illness, and mood. The confidence moves first, within about six weeks. Quality of life within three months. The mood gain holds for a year.

The research is promising, and it is growing: more than 140 randomised trials so far, and the largest chronic pain trial ever run came out this year with a coach on the team.

What a health coach actually does

A health coach starts where the visit stopped: with your life. A health coach meets you where you are. First, what is your condition, and what has your doctor said. Then the part no visit has time for: your life. What is holding you back from getting better. The things you have not shared with your doctor, or with anyone.

From there we organize, one piece at a time: your days, your thoughts, your habits. We look for what is really holding you back, and we dig. Sometimes the digging ends at your doctor's door, with a question you did not know you could ask: a specific blood test, a medication you are not happy with. A health coach does not answer those questions. A health coach makes sure you walk in and ask them, without doubting yourself, and speak to your doctor with confidence.

And a health coach can follow up with you every day. Your doctor cannot.

Mayo Clinic, which has run wellness coaching inside its own hospital for years, describes the work like this: "wellness coaching does not pathologize or diagnose problems." The coach helps you "feel like a normal person with a normal problem," and then builds the plan week by week. Three months after their coaching ended, Mayo's own patients "not only maintained the changes, they exhibited signs of further improvement."

Who already hires health coaches

The largest health systems in the world have stopped asking whether coaching works and started hiring.

"coaching is the lynchpin of the transformational model."

Dr Kavitha Reddy, who leads the Whole Health program at the US Department of Veterans Affairs, where more than two thousand trained health coaches work in its hospitals and clinics

"They are experts in behaviour change and focus on improving health related outcomes by working with people to set personalised goals and change their behaviours."

NHS England, on the health and wellbeing coaches it employs inside GP practices

"I've been telling the CFO of Cleveland Clinic that we need to hire 10,000 health coaches there."

Dr Mark Hyman, founder of the Center for Functional Medicine at Cleveland Clinic

What a health coach is not

A health coach never replaces your doctor, and never tries to. A health coach never replaces medical advice. A health coach does not prescribe medication and does not tell anyone to stop taking it. What a health coach can say is: you are feeling better, so take that to your doctor and ask whether the dose can change. The decision stays with your doctor. The confidence to ask comes from the work we do together.

Bottom line

A doctor treats the illness. A health coach works on the life it sits in: the sleep, the food, the stress, the habits, the questions you never get to ask. The research is promising, and the first thing it shows changing is confidence; everything else follows from that. If you live with chronic illness or pain, you need someone who understands the moments that nobody else can, and helps you through them. Someone you can share everything with, who always wants the best for you. Someone who turns the habits and the mindset that hold you back into the ones that move you forward.

Your diagnosis is written in eighteen minutes. Your illness is lived in the other five thousand hours.

That is where a health coach works. That is where I work.
