Can Stress Cause Physical Symptoms? What the NHS, Mind and the HSE Each Say — and When Not to Blame Stress

Yes — but the NHS names five physical symptoms of stress and Mind names fifteen. Both lists, the mechanism, the look-alike causes and the 999 rules.

Yes. The NHS states plainly that stress “can cause many different symptoms” affecting how you feel physically as well as mentally. What almost no article tells you is how much the authoritative UK sources differ on the detail: the NHS names five physical symptoms of stress, Mind names fifteen, and the Health and Safety Executive names none at all — it lists behavioural signs instead. All three lists are below, side by side, with the symptoms that must never simply be put down to stress.

Last reviewed: 22 September 2026.

This page is general information, not medical advice, and nobody here is a clinician. It sets out what each named UK source says, with the date that source last reviewed its page. It cannot tell you what is causing your symptoms — that is what a GP appointment is for, and there is a sourced section below on when to make one, when to call 111, and when to call 999.

The three UK lists, side by side

These are the physical symptoms each source publishes. Nothing here is merged or paraphrased into a single invented list.

Physical symptom NHS Mind
Headaches yes (“headaches or dizziness”) yes (“muscle aches and headaches”)
Dizziness or fainting yes (“headaches or dizziness”) yes (“feeling sick, dizzy or fainting”)
Muscle tension or pain yes yes
Stomach problems yes “indigestion or heartburn”; “constipation or diarrhoea”
Chest pain or faster heartbeat yes “chest pains and high blood pressure”
Sexual problems yes —
Difficulty breathing — yes
Panic attacks — yes
Blurred eyesight or sore eyes — yes
Sleep problems listed under behaviour yes
Fatigue — yes
Sudden weight gain or loss listed under behaviour, as eating too much or too little yes
Rashes or itchy skin — yes
Sweating named in the causes section yes
Changes to periods or menstrual cycle — yes
Existing physical health problems getting worse — yes

The HSE’s list is different in kind. Writing for managers rather than patients, it names changes in how someone acts — taking more time off, arriving for work later, being more twitchy or nervous — and changes in how they think or feel: mood swings, being withdrawn, loss of motivation, commitment and confidence, and “increased emotional reactions – being more tearful, sensitive or aggressive”. At team level it lists arguments, higher staff turnover, more reports of stress, more sickness absence, decreased performance, and more complaints and grievances.

Why the difference matters: if you go looking for a definitive UK list of “the physical symptoms of stress”, there isn’t one. There is a short clinical list from the NHS, a longer patient-facing list from a mental health charity, and an occupational list from the workplace regulator. A page that gives you one number of symptoms and calls it settled is flattening a real disagreement about scope.

What is actually happening in the body

The NHS gives the mechanism in two sentences, and it is worth having them exactly:

“When you’re feeling anxious or scared, your body releases stress hormones such as adrenaline and cortisol. This can be helpful for some people and stress might help you get things done or feel more motivated. But it might also cause physical symptoms such as a faster heartbeat or sweating. If you’re stressed all the time, it can become a problem.”

Mind frames it the same way: “Our bodies produce hormones to respond to stressful situations. These hormones can have many physical effects.”

Two things follow from that, and both are in the sources. First, stress is not by definition harmful — the NHS says some people find it helpful or even motivating. Second, the problem is duration: the NHS’s condition is “if you’re stressed all the time”, and Mind’s is that the physical effects “can get worse” if we experience high levels of stress, or stress for a long period of time.

The NHS also says something that explains why people arrive at this question at all: “It’s not always easy to recognise when stress is the reason you’re feeling or acting differently.”

Symptom by symptom: what else it could be

This is the section the question really needs, because “yes, stress can cause that” is only half an answer. For each of the common physical symptoms, here is what else the NHS says can cause it.

Chest pain

The NHS publishes a table matching chest pain patterns to possible causes. Its anxiety row reads: “An often sharp, continuous pain triggered by worries or a stressful situation, heartbeat gets faster, sweating, dizziness” — possible cause: anxiety, depression or panic attack.

But that row sits alongside these, from the same table:

What the chest pain is like What the NHS says it might be
Starts after eating, bringing up food or bitter tasting fluids, feeling full and bloated Heartburn or indigestion
Starts after chest injury or chest exercise, may get worse when you breathe in, feels better when resting the muscle Chest sprain or strain
Often sharp, continuous, triggered by worries or a stressful situation, heartbeat faster, sweating, dizziness Anxiety, depression or panic attack
Gets worse when you breathe in, coughing up yellow or green mucus, high temperature Chest infection, pneumonia or pleurisy
Tingling feeling on skin, skin rash appears that turns into blisters Shingles

The NHS’s own instruction on that page, verbatim: “Do not self-diagnose – see a GP if you’re worried.” And it opens the page with: “In most cases, chest pain is not caused by a heart problem.”

A racing or thumping heart

The NHS lists “stress and anxiety” among the common causes of heart palpitations — alongside strenuous exercise, lack of sleep, medicines, and alcohol, caffeine, nicotine and recreational drugs.

It also lists causes that are not stress and need finding: iron deficiency anaemia, an overactive thyroid, a heart rhythm problem or other heart problems such as heart valve disease. It notes that palpitations can be a sign of the menopause, and that some people get them during pregnancy.

Its framing: “Heart palpitations are common and not usually a sign of anything serious.”

Stomach problems

The NHS’s page on a healthy tummy — reviewed on 21 July 2026, the most recently checked source on this page — puts it directly: “In some people, stress slows down digestion, causing bloating, pain and constipation, while in others it speeds it up, causing diarrhoea and frequent trips to the toilet. Some people lose their appetite completely.” It adds that stress can worsen symptoms of digestive conditions like stomach ulcers and irritable bowel syndrome.

That cuts both ways, which is the useful part: the same symptom can be stress in one person and speeding-up in another. If gut symptoms are the main event, our guide to the best foods for gut health in the UK covers what the NHS, Guts UK and the British Dietetic Association each recommend, and the bowel symptoms that need a GP rather than a diet change.

Headaches, and waking with one

“Headaches or dizziness” is first on the NHS’s physical list, and Mind lists “muscle aches and headaches”. If the headache is specifically there when you wake up, that narrows the field considerably, and our guide to waking up with a headache every morning works through the shortlist of NHS-listed causes and how to tell them apart.

Tiredness

Mind lists fatigue; the NHS’s stress page lists “sleeping too much or too little” under changes in behaviour rather than as a physical symptom. Persistent exhaustion has a long list of causes the NHS checks for with blood tests, and attributing it to stress without ruling those out is the mistake this page exists to prevent — the tests to ask your GP for when you are always tired sets out what each one rules out.

The most important sentence on this subject

It comes from the HSE, in guidance written for managers, and it applies just as well to anyone reading their own symptoms:

“These signs can be symptoms of other conditions.”

The HSE’s instruction that follows is the correct action: “If managers are worried that a worker is showing some of these signs, they should encourage them to see their GP.”

That is the whole safety argument of this page in two lines. Stress can cause physical symptoms. It is also the most available explanation for almost any symptom, which makes it the easiest thing to hide behind while something treatable goes unchecked — anaemia, a thyroid problem, a heart rhythm problem, a digestive condition. None of those are ruled out by the fact that you are also under pressure.

What stress can do that is more than a symptom

Mind names two outcomes that are more serious than the ordinary list, and both are worth knowing about precisely because they are so often left out.

  • Takotsubo syndrome, “sometimes referred to as broken heart syndrome or takotsubo cardiomyopathy”. Mind says “This can feel similar to a heart attack” and points to British Heart Foundation information on it.
  • Secondary amenorrhoea — “when you don’t get your period for 3 months or more”. Mind points to NHS information on missed or late periods.

Mind’s framing for both is careful and we keep it: these are things stress “may cause” “in some cases”, if we experience high levels of stress or stress over a long period.

Neither is a reason to treat chest pain at home. The NHS’s 999 advice below applies whatever anyone believes the cause to be.

Stress and anxiety are not the same page

The NHS keeps them apart, with different symptom lists, and the difference is useful for working out which advice applies to you.

NHS “Stress” NHS “Anxiety, fear and panic”
Physical symptoms listed 5 11
Includes breathlessness no yes
Includes shaking no yes
Includes loss of appetite listed under behaviour, as eating too much or too little yes
Includes constipation or diarrhoea under “stomach problems” yes, named separately
Separate panic-attack list no yes
Described as “usually a reaction to mental or emotional pressure… often related to feeling like you’re losing control over something” anxiety, fear and panic as feelings and symptoms

The NHS’s panic attack list is specific: a racing heartbeat; feeling faint, dizzy or light-headed; feeling that you’re losing control; sweating, trembling or shaking; shortness of breath or breathing very quickly; a tingling in your fingers or lips; feeling sick. It adds the two facts people most need in the moment: “A panic attack usually lasts 5 to 20 minutes” and “They can be frightening, but they’re not dangerous and should not harm you.”

What causes stress, in the NHS’s own categories

The NHS says stress is “usually a reaction to mental or emotional pressure”, often related to feeling like you’re losing control over something — “but sometimes there’s no obvious cause”. The examples it gives:

  • work — feeling pressure at work, unemployment or retirement
  • family — relationship difficulties, divorce or caring for someone
  • financial problems — unexpected bills or borrowing money
  • health — illness, injury, or losing someone

And the one that surprises people: “Even significant life events such as buying a house, having a baby or planning a wedding could lead to feelings of stress.”

What the NHS says to try

Its “do” list, in its own words: talk about your feelings to a friend, family member or health professional; read its 10 stress busters, including getting started with exercise and setting aside time for yourself; use easy time-management techniques; use breathing exercises for stress; plan ahead for stressful days or events; consider peer support; and listen to its free mental wellbeing audio guides. It names Samaritans, on 116 123, as a number to call if you need someone to talk to.

Its “don’t” list matters at least as much: do not try to do everything at once — set small targets you can easily achieve; do not focus on the things you cannot change; try not to tell yourself that you’re alone; and “try not to use alcohol, cigarettes, gambling or drugs to relieve stress – these can all contribute to poor mental health”.

When to see a GP, call 111, or call 999

This section is the NHS’s own wording, not a summary of it.

See a GP if:

  • you’re struggling to cope with stress
  • things you’re trying yourself are not helping
  • you would prefer to get a referral from a GP

Call NHS 111 or ask for an urgent GP appointment if:

  • you need help urgently, but it’s not an emergency

NHS 111 can tell you the right place to get help if you need to see someone. You can call 111 or get help from 111 online.

Call 999 or go to A&E now if:

  • you or someone you know needs immediate help
  • you have seriously harmed yourself — for example, by taking a drug overdose

The NHS adds: “A mental health emergency should be taken as seriously as a physical emergency.” And: “Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance. Bring any medicines you take with you.”

You do not always need a GP first. The NHS states that NHS talking therapies for anxiety and depression may be able to help with stress, and that “If you’re 18 or over (or 16 or over in some areas), you can refer yourself directly without talking to a GP.” If you’re under 18, it points to its mental health support for children and young people.

The physical emergencies that override all of the above

If a symptom on the list below is present, the NHS’s instruction is to call 999 — regardless of how stressed you have been.

Chest pain. Call 999 if you get sudden pain or discomfort in your chest that does not go away — “the pain can feel like squeezing or pressure inside your chest, burning or indigestion”; if you get pain that spreads to your left or right arm, or your neck, jaw, stomach or back; or if you have chest pain and you feel sweaty, sick, light headed or short of breath. The NHS says: “You could be having a heart attack. Call 999 straight away as you need immediate treatment in hospital.”

Palpitations. Call 999 or go to A&E if you currently have heart palpitations and they do not go away, or you also have chest pain, shortness of breath, or feeling faint or fainting. If you’ve had these symptoms but they have now stopped, the NHS says to ask your GP surgery for an urgent appointment, call 111, or get help from 111 online.

See a GP about palpitations if you feel well but they keep coming back or are happening more often, they last longer than a few minutes, you have a heart condition, or you have a history of heart problems in your family.

What we left out, and why

Several claims appear on most “physical symptoms of stress” pages and are absent here because no NHS, Mind or HSE source we fetched supports them.

  • A percentage of GP appointments that are stress-related. Widely quoted, not in any of the sources above.
  • Cortisol levels you can measure, or “adrenal fatigue”. The NHS names adrenaline and cortisol as the hormones released. It does not describe a testable cortisol level for stress, and none of our sources recognises adrenal fatigue as a condition.
  • Stress as a cause of a specific named illness, beyond Mind’s two examples and the NHS’s statement that stress can worsen symptoms of stomach ulcers and IBS.
  • A number of days or weeks after which stress becomes “chronic”. Neither the NHS nor Mind publishes a threshold.
  • Supplements, adaptogens or specific breathing counts. The NHS points to its own breathing exercises for stress rather than prescribing a ratio, so we do too.

Once you know it is stress, what do you do about the cause

Recognising a symptom is one thing; changing what produced it is another, and in the UK that has a framework behind it. Your employer has a legal duty to assess the risk of work-related stress and act on it, using the six HSE Management Standards — demands, control, support, relationships, role and change. Our guide to managing work stress quotes all six in full and sets out what to ask for.

Frequently asked questions

Can stress cause chest pain?

The NHS lists “chest pain or a faster heartbeat” among the physical symptoms of stress, and its chest pain page lists anxiety, depression or a panic attack as a possible cause of “an often sharp, continuous pain triggered by worries or a stressful situation” with a faster heartbeat, sweating and dizziness. But the NHS also says not to self-diagnose, and gives 999 rules for chest pain that apply whatever you think is causing it.

How long can stress symptoms last?

The NHS does not publish a duration. Mind says that if we experience high levels of stress the physical effects can get worse, and that this can also happen if we experience stress for a long period of time. The NHS’s own trigger for seeing a GP is not a length of time — it is that you’re struggling to cope, or that the things you’re trying yourself are not helping.

Can stress affect your periods?

Mind lists “changes to your periods or menstrual cycle” among the physical signs of stress, and separately names secondary amenorrhoea — not getting a period for 3 months or more — among the more severe or long-term physical health problems stress may cause in some cases. It points readers to NHS information on missed or late periods.

Is stress the same as anxiety?

The NHS treats them as separate topics with separate symptom lists. Its stress page names five physical symptoms; its anxiety page names eleven, including breathlessness, shaking, loss of appetite and constipation or diarrhoea, and adds a separate list for panic attacks. The NHS describes stress as usually a reaction to mental or emotional pressure, often related to feeling like you’re losing control over something.

Can I get therapy for stress without seeing a GP first?

In England, yes. The NHS states that NHS talking therapies for anxiety and depression may be able to help with stress, and that if you’re 18 or over — or 16 or over in some areas — you can refer yourself directly without talking to a GP. If you’re under 18, the NHS points to its mental health support for children and young people.

Can stress cause a heart problem, or just feel like one?

Mind names takotsubo syndrome, sometimes called broken heart syndrome, among the more severe physical health problems stress may cause in some cases, and says it can feel similar to a heart attack, pointing to British Heart Foundation information on it. That is not a reason to treat chest pain as stress. The NHS’s 999 advice for chest pain applies regardless of what you believe the cause to be.

My manager says I look stressed. What does the HSE expect them to do?

The HSE says employers must assess the risks of work-related stress in the workplace and take action to protect workers. Its guidance for managers lists signs to watch for in a worker, then adds the caveat that matters: “These signs can be symptoms of other conditions.” Its instruction is that if managers are worried a worker is showing some of these signs, they should encourage them to see their GP.
