Opening
"I know it's silly. But my mind won't stop planning disasters."
Anjali was thirty-two, an operations coordinator for a logistics firm in Patna. She had been a worrier since school, but over the past two years the worry had moved in permanently. She checked whether the gas was off four times before leaving the house. She rehearsed every email before sending it. She lay awake listing everything that might go wrong at work, at home, with her parents' health, and with her son's school. "The strange thing," she told me, "is that nothing bad has actually happened. I just can't believe that it won't."

Generalized anxiety disorder (GAD) is a long-lasting condition in which a person experiences excessive, hard-to-control worry about many everyday matters, on more days than not, for at least six months. The worry is accompanied by physical tension and restlessness, and it causes significant distress or impairment. "Generalized" means the worry is not tied to one specific object or situation; it roams from health to money, from family to work, and often settles on whatever is next.
In medical language, GAD is one of the most common anxiety disorders, and studies report lifetime prevalence estimates ranging from around 8% to 13% in some populations, with substantial variation between countries and methods. It is more common in women, and often begins in childhood or early adulthood. Because the symptoms feel like "just being a worrier", many people carry GAD for years before they seek help.
GAD, in one sentence each
| Term | Plain meaning |
|---|---|
| GAD (full form) | Generalized Anxiety Disorder: persistent, excessive worry across many areas of life |
| GAD definition | Excessive anxiety and worry occurring more days than not for at least six months, hard to control |

| GAD in psychiatry | A recognised diagnosis requiring assessment, with treatment options similar to other anxiety disorders |
Normal worry or a disorder?
Worry is a dial, not a switch
Everyone worries. Worry helps us prepare for exams, plan for money and notice risks. The question is whether worry is proportionate, whether it can be put down, and what it costs.
Useful worry: short, solvable, endsMostly usefulStickyHard to put downDisordered worry: endless, vague, stuck
| Feature | Ordinary worry | GAD |
|---|---|---|
| Focus | A specific problem with a possible solution | Many topics, often hypothetical, rarely resolved |
| Duration | Ends when the issue is dealt with | Most days, for six months or longer |
| Control | Can be set aside | Feels impossible to stop, even when recognised as excessive |
| Body | Brief tension | Persistent tension, restlessness, tiredness, poor sleep |
| Impact | Temporary, manageable | Affects work, family, sleep and decisions |
The alarm analogy
A smoke alarm protects the house. But one that goes off every time someone makes toast does not make the house safer; it wears everyone out. GAD is a threat-detection system that keeps sounding, even when there is no fire.
Symptoms
The six signs that travel together
DSM-5-TR describes GAD using five core features.1 For adults, the diagnosis requires excessive worry on most days for six months, difficulty controlling the worry, and at least three of six associated symptoms. The worry must cause clinically significant distress or impairment, and it must not be better explained by another condition or by a substance or medical cause.
Restlessness
Feeling keyed up or on edge; difficulty settling
Fatigue
Easily tired, even without physical effort
Concentration
Mind goes blank; hard to focus on reading or tasks
Irritability
Short-tempered, snapping at people you love
Muscle tension
Neck, shoulders, jaw; headaches from clenching
Sleep disturbance
Trouble falling or staying asleep; unrefreshing sleep
Physical signs that bring people to the doctor first
Many people with GAD first see a general physician or a gynaecologist, or a gastroenterologist for stomach symptoms. Common physical features include palpitations, breathlessness, sweating, dizziness, frequent urination, stomach discomfort, nausea, and chest tightness. These are real symptoms of the body's stress response, not signs of a heart or stomach disease, but they should be checked medically at least once, especially when they are new.
The mind's signs
The worry itself often takes the form of "what-if" questions: What if I lose my job? What if my child is hurt? What if I forget the medicine? Anticipating disaster, seeking reassurance, asking the same question repeatedly, and imagining worst-case scenarios are typical. Many people also describe a feeling of dread that has no clear object. When the same thoughts circle for hours, it overlaps with what psychologists call rumination, the habit of replaying the same thought.
Why worry persists
The loop that keeps the alarm ringing
Researchers have studied worry for decades. Thomas Borkovec and colleagues showed that worry often works as a mental attempt to solve problems and prevent harm.4 The trouble is that it rarely produces answers, and the relief it brings is brief. Michelle Newman and Sandra Llera later proposed that worry is also a way of avoiding uncomfortable emotions and uncertain outcomes, a shortcut that feels protective but keeps the fear going.5
- 1 · TriggerUncertainty: a message unanswered, a test result pending
- 2 · Worry"What if...?" Planning for every possible outcome
- 3 · ReliefBrief calm from reassurance, checking or avoiding
- 4 · ReinforceThe brain learns uncertainty is dangerous, and worry returns
Problem or worry? Sort it in one minute
It is a problem if...
you can name one concrete next step; the outcome depends on an action you can take today; a decision is due; a deadline is real.
It is worry if...
the question is "what if" with no clear answer; you have already checked it many times; it returns after reassurance; it is about someone else's future.
A practical rule
Act on problems; practise letting go of worries. For a problem, plan one step. For a worry, notice it, name it, and return to the present task. The skill is in the sorting, which improves with practice.
Intolerance of uncertainty: the hidden engine
A consistent finding in research is that people with GAD find uncertainty very hard to tolerate. They treat "maybe" as "probably bad", and they respond by checking, reassurance-seeking or avoiding decisions. This is why medical test results, job offers and family news can set off days of tension even when the outcome is not yet known. Treatment therefore often teaches people to live with reasonable uncertainty, rather than trying to eliminate it.
Causes
A combination, not a single cause
GAD develops through several overlapping routes. No single gene, brain chemical or life event explains it. Some people are born more sensitive to threat; others learn anxiety from families and experiences; many carry both. Older explanations often spoke of a simple "chemical imbalance". Current research describes it instead as changes in how several brain systems, including those for threat detection, emotional regulation and learning, work together. This is a more accurate picture, and it also explains why therapy can change the brain as well as medicines can.
| Factor | What research suggests |
|---|---|
| Temperament | Early cautiousness and sensitivity to novelty, sometimes called behavioural inhibition, increase risk |
| Family and genes | Anxiety disorders run in families; the inherited part is moderate, not fixed |
| Learning | Over-protection, modelling of worry by parents, and learned avoidance all contribute |
| Life stress | Financial pressure, illness, bereavement, unstable work and trauma can trigger or maintain GAD |
| Thinking style | Intolerance of uncertainty, perfectionism and overestimation of threat are central features |
| Substances and medical | Excess caffeine, nicotine, alcohol withdrawal, cannabis, thyroid disease and some medicines can produce GAD-like symptoms |
A note on caffeine and tea
Many people in India drink several cups of chai or coffee a day. High caffeine intake can cause palpitations, restlessness and insomnia that look exactly like GAD. Reducing it is often one of the first steps, and it should be considered before adding medicines.
Diagnosis
How a psychiatrist makes the call
There is no blood test or scan for GAD. Diagnosis rests on a careful clinical interview, supported by screening tools and a check for other causes. A good assessment asks not only about worry but about its pattern, its effect on daily life, past episodes, family history, substance use and medicines. If you are unsure what a first appointment involves, read what happens at your first visit to a psychiatrist.
Step 1Interview
Detailed history of worry, its content, duration and control, plus body symptoms and daily functioning.
Step 2Screening
Questionnaires such as the GAD-7 help measure severity and track change. They support, but cannot replace, a diagnosis.
Step 3Medical check
Thyroid, blood count, glucose and sometimes ECG or other tests, depending on symptoms. Caffeine, alcohol, cannabis and medicines are reviewed.
Step 4Differential check
Consider depression, panic disorder, social anxiety, OCD, health anxiety, PTSD and adjustment disorder, which can co-exist.
The GAD-7: a quick screen, not a verdict
The GAD-7 asks seven questions about how often, over the past two weeks, a person has been bothered by feeling nervous, unable to stop worrying, worrying too much, trouble relaxing, restlessness, irritability and fear that something awful will happen.6 Each item is scored from 0 to 3. A total of 5 or more suggests mild anxiety, 10 or more moderate, and 15 or more severe. A high score merits a proper assessment; a low score does not rule out distress that a conversation might reveal.
Some conditions look similar from the outside. Fear of being judged in company is social anxiety rather than GAD, and constant worry with loss of interest and low mood may point to depression, explained in our guide to overthinking and depression.
Treatment
What works, and what the evidence says
A 2024 network meta-analysis of randomised trials, published in European Psychiatry, compared psychotherapies for GAD in adults.2 Cognitive behavioural therapy was the only approach that remained significantly better than usual care for anxiety severity at three to twelve months after treatment. Third-wave approaches and relaxation therapy showed short-term benefit. CBT is therefore the reasonable first-line psychological treatment; our explainer on how CBT works shows what happens in the sessions.
The treatment ladder
- 1Self-help and lifestyle
Regular sleep and wake times, moderate exercise most days, reducing caffeine and alcohol, a fixed "worry time" of 20 minutes earlier in the day, and writing worries down with a next step. Helpful for mild GAD, and always part of treatment.
- 2Psychological therapy
CBT, in person or guided online, usually 12 to 20 sessions. Work includes identifying worry patterns, testing predictions, planned exposure to uncertainty, and reducing checking and reassurance-seeking.
- 3Medicines
SSRIs and SNRIs are first-line medicines. They take 4 to 6 weeks to work, must not be stopped suddenly, and people under 25 need closer monitoring in the early weeks. Buspirone is an option for some. Pregabalin showed favourable efficacy and tolerability in a 2025 meta-analysis of trials,3 but it carries a risk of dependence and misuse and is controlled in several countries, including India; it should be prescribed with care. Benzodiazepines may ease acute symptoms for a short time but carry dependence risks and are not suitable for long-term use.
- 4Combined or specialist care
For severe or long-standing GAD, or where depression or substance use co-exist, a combined plan may be needed. Specialist review is important when several medicines are considered or when response is poor.
How a psychiatrist chooses between these medicines, and why doses are started low, is explained in how psychiatrists in India decide which medicine to prescribe. At the clinic, talking treatments are offered through psychology and counselling and the behavioural therapies service.
Living with it
Everyday tools for a quieter mind
Schedule a worry time
Choose 20 minutes earlier in the day. When a worry appears at other times, note it and return to it then. Most worries lose force by the time the slot arrives.
Reduce reassurance
Asking family or the internet "is it going to be okay?" feeds the loop. Try waiting a few minutes before checking, and notice what happens.
Name the worry
"This is worry about the report, not a fact about tomorrow." Labelling thoughts as thoughts reduces their grip, in research and in practice.
Protect your sleep
Worry and poor sleep feed each other. A consistent routine and a wind-down period without news or messages can break the cycle.
Move your body
Brisk walking, yoga or cycling reduce physical tension and improve sleep. Regular exercise is one of the most consistently recommended lifestyle steps.
Limit news and scrolling
Constant exposure to alarming content keeps the alarm sounding. Set fixed times for news and avoid it late at night.
For quick calming techniques sorted by the time you have, from a 60-second breath to a 20-minute walk, see how to relax your mind from stress.
Indian pressures that often sit under GAD
Exams and competitive jobs
Long, uncertain selection processes and repeat attempts can keep the mind in "what if" mode for years. Name the uncertainty and plan what you can control. Students will find more in exam stress: when pressure helps and when it harms.
Family responsibility
Caring for ageing parents, financial obligations and joint-family expectations often carry constant low-level worry. Share the load where you can, and look after yourself too.
"Tension tablets" and home remedies
Some people take sedatives or antihistamines for nerves, or use herbs in large doses. Sedatives cause dependence; some herbal products have interactions. Always check with your doctor before starting or combining anything.
Stigma and silence
Many people call their anxiety "tension" to avoid the word "mental". Naming it accurately makes it easier to get the right help.
What progress looks like
Anjali's twelve weeks
Anjali started CBT with a weekly 50-minute session, combined with a daily worry slot and gradual exposure to uncertain tasks, such as sending emails without rereading them more than once. She did not take medicine initially; after the first assessment we agreed to review that choice at week six. Her GAD-7 score was tracked at each session. The chart is illustrative, based on common patterns in our clinic, not a single patient record.
What changed
By week four Anjali was checking the gas once, not four times. By week eight she was sending work emails with a single review, and she had begun to say "I don't know yet" aloud in meetings without feeling that she had failed. Her sleep improved first, then her shoulder tension eased. The worry did not disappear, and she has said that she still notices it. What changed was her relationship to it: the alarm now sounds, she says, and then she decides whether there is a fire.
What we did not do
We did not prescribe tablets to "switch off" anxiety, we did not promise a cure, and we did not ask Anjali to avoid the things she feared without first building the skills to face them.

Your questions
Frequently Asked Questions
What is GAD?
Generalized anxiety disorder is a long-lasting condition in which excessive worry about many everyday matters occurs on most days for at least six months, is hard to control, and causes distress or impairment.
What is the full form of GAD?
Generalized Anxiety Disorder. It is a recognised psychiatric diagnosis in DSM-5-TR and ICD-11.
Is GAD a mental illness or just a personality trait?
It is a diagnosable mental health condition. Worry-prone temperament can be a risk factor, but GAD causes persistent impairment that needs assessment and treatment.
What are the symptoms of GAD?
Excessive worry most days, difficulty controlling it, plus at least three of: restlessness, fatigue, poor concentration, irritability, muscle tension and sleep disturbance in adults.
What causes generalized anxiety disorder?
A combination of temperament, genetic risk, learning, life stress, thinking style, and substances or medical conditions. No single cause explains it.
Can GAD be cured?
Many people improve substantially and some recover fully with CBT, medicines or both. Some keep mild worry as part of life, and the goal is that worry no longer runs their lives.
Are anxiety tablets safe for long-term use?
SSRIs and SNRIs are used long term under review. Benzodiazepines are not suitable for long-term use because of dependence. Any medicine should be started, reviewed and stopped only with your doctor.
When should I see a psychiatrist?
When worry lasts more than a few weeks, affects sleep, work or relationships, or comes with panic, low mood or substance use. Seek urgent help if you have thoughts of harming yourself.
